You are correct. For whatever reason I thought you were dealing with the FRRP. I also did not realize the Raptor 100s were seeing high failure rates. I wonder if installing a catch all type inline filter before the Raptor would help prolong the pump.JR

The Raptor and the AD100 use the same motors. I believe the biggest contributing factors that lead to the AD100 lasting longer are that it is mounted on the frame rail rather than the engine. No heat or vibration to deal with, and the pump is pushing fluid rather than pulling. The AD100 also draws fuel through the f/w separator before going through the pump so any debris is caught in the filter before going through the pump. The Raptor only has a small screen in the inlet of the pump. A fella I know was going to trash his AD100 because the motor was burned up, so I mated my Raptor motor to the AD100 frame with 1/2" fuel line from top of tank to OEM canister to VP. 18 psi at idle and 15-16 psi under heavy engine loads.

Boy does that bring back memories! Kid was 3 months old when I brought him home, he's now 14. My sons are 10 and 8 and they have been very close to Kid ever since they were old enough to crawl. The bond they both have with him is pretty special. Enjoy every minute with that little puppy the time we have with them is much too short. JR

Some builders will put a sticker on the top of the pump but other than something like that no way that I know of.JR

If the VP has high miles then it could be a part of it. Usually the ecm will not effect mileage though unless there's some real driveability issues. Generally you will get a check engine light if the VP is maxed out on advancement but not always. Injectors you can always pull and have them pop tested to verify before you spend money on new ones unless your wanting to upgrade anyway.JR

It depends on what the intake temps are. If you start your truck for a minute, let the grid heaters cycle a few times, then shut it off and restart it the wts light is not going to stay on as long as before because the intake temps are still warm. Is there an issue with the way the truck is running?JR

Hey Dennhop, glad you got it figured out. Not sure what part of Indiana your moving to but the further north you go the more your going to need it, especially with the humidity they tend to see. Good luck with your move and be safeJR

Tom why isn't your truck in that nice big shop of yours? She looks mighty cold sitting out there! You look like you've got your hands full, it was 56 degrees in good ol Ashtabula County today! Shorts and t shirt weather! JR

We have lots of Toluene on site as well. NASTY stuff. They show that video every year in our HAZMAT refresher. - - - Updated - - - A little off track but this one has always amazed me. I forget how many miles away the guy video taping was but it was taken from a ways out. Heres the same video but without all the bs commentary. Much better to watch this one, puts it into perspective how big it really was. https://www.youtube.com/watch?v=gSflyJ_r77k&feature=youtube_gdata_player

There are alot of mixed reviews about them for sure. People either love em or hate em. I havent had them long enough to form an opinion but so far I have no complaints. They would not have been my first choice but tire choices are very limited in 285/75/17. Interesting yours were loud I can't even hear mine over the engine going down the road. As far as the tread pattern if you need an agressive tire then a M/T is the way to go, these are not considered a M/T. They do grab much better than the OEM BGFs that came on my 12 wheels though. The other day I pulled my trailer loaded with my dads broken down Massie up out of the field next to his house and barely spun a tire in 2 wheel drive. With the tight tread pattern I could see thick clay type mud being a problem, but we don't have much of that around here.

I work at Cristal Global in Ashtabula. You probably don't recognize the name, it used to be Millennium and before that was SCM Chemicals back in the 80s. I think before that it was called Gulf Western. Plant 1 down the road from my plant was originally built and operated by Sherwin Williams in the 70s I believe. Now we are all the same company. We make Titanium Tetrachloride (base ingredient in all titanium products) and Titanium Dioxide (white pigment found in paints and plastics). I work in maintenance and mainly weld and fit pipe or run the cranes so I'm not on the battle field very often like the operators or the field mechanics are. LOLJR

I'll offer my take...I ran a set of 285/75/16 Good Year Duratracs for 3 years and loved them. The only downfall was when hooking to a trailer north of about 8k lbs the truck really had to work hard. A combination of the 3.54 gears and taller tires. I would really love to do a 3.73 gear split and have even considered swapping to 4.10s for this reason. Early last year I came across a brand new set of take offs from 12 Laramie, wheels and tires for 400 bucks. I thought it was a smokin deal but the A/T tread design is very hindering for me. I run a lot of fields and soft oil well drives on my families farm and I find myself reaching for 4wheel drive everytime I leave the hard pan. I couldn't even pull my empty trailer up the slight incline of my back drive in 2wheel drive if it had been raining for any length of time. Very frustrating. I dealt with it up until a few weeks ago and when our first good snow storm hit I couldnt deal with them anymore. I would have loved to of gotten another set of the Good Year Duratracs but theyre only available up to 285/70 in a 17" wheel and I don't particularly like the way they look on the factory width rims, so I opted for a 285/75/17. I was really torn about what tread pattern to go with I really wanted another M/T but I settled for a balance of a M/T and an A/T and went with the TerraGrapplers. I've already tested them out a few times, got to drag a half ton Ford down a nasty lease road that has only been cut with a dozer and has no base yet. They are light years ahead of an A/T pattern but can not compare with a M/T like my old Duratracs. They balanced well with little weight and are super smooth up to 80 mph. I rarely drive over 70 on the freeway but wanted to get a feel for them and overall they seem pretty good. Time will tell how they hold up. My next step is going to be to find another set of wheels on the cheap and remount the 265/70s back up so I have a set of tires for towing season next summer. To answer your question if your running the back roads alot and find yourself on soft ground, I would personally stick with a 285/75 and stay away from the A/T patterns. You will lose a little fuel mileage but even when I was running my Duratracs I was still clearing 19 mpg empty highway driving. Where you will see more of a drop is hauling or lots of stop and go driving. Still worth the trade off IMO, yes I want to get as good of fuel mileage as I can but ultimately it doesnt do me any good if I can't get where I need to go.

Yep, H2S will desensitize you in under a minute...if you ever catch a breath of it in strong concentrations you better be heading the other way quick. We have a lot of it on site at work (it's actually a byproduct) and has been responsible for killing a few people. This was several years ago. Last year our sister company in Europe had a similar situation happen. They took delivery of a large vessel that had been padded with nitrogen because it was imperative the internals were kept dry. The maintenance guy popped the man way and then stood by as hole watch while an engineer went in to do inspections. He got down in the tank (man way at the top of a vertical vessel) and went down. Maintenance guy called the control room to call 911, supervisor heard the call on the radio and ran out to investigate. He took it upon himself to crawl in after the engineer and went down almost immediately. By the time the fire dept arrived they were both dead. There are lots of silent killers at the plant I work at, and we actually have our own first responder team that I am a part of. We train every 3 months on confined space rescue involving rappelling and ascending and the use of 3 and 4 to 1s. We recently had our annual refresher from a company out of Michigan and they taught us how to make a harness out of climbers rope. Pretty neat stuff. JR

That would put them at about 300% of their value, IMO. Even though the cool factor would be sky high I just cant see a 25 year old truck being worth anymore than about 5k, and at that it would have to be immaculate and well maintained....JR

I wonder if those 2 guys could have put their phones down if 7 people would have what it took to roll that car up on its side enough to get her head out of the water...On hard ground it would be no problem but hard to say being in the water like that. I do know that 7 people with their adrenaline pumping can do some pretty amazing things. Even if it were just enough to shove a log or something similar under the roof, it doesn't appear that she was under the water very much....Of course my first move would have been cutting the seatbelt (I ALWAYS carry a buck knife on my side). I heard mention of a knife mid way through the video so not sure where the hang up was....its hard to say what you would or wouldn't do in that situation but I would have went down fighting, that's for sure... JR

Sounds like a front main seal, or possibly the oil pump if it's not leaking directly around the crank. The oil pump is sealed to the cover with a large o ring. I would also love a diesel powered Toyota its something I've been looking at for a long time but they're pretty dang rare, at least here in the states. They were much more common south of the border and over seas....dang EPA. BTW, loose chains eat timing covers and guides ;)JR

Can you temporarily put your mechanical gauge into the port where your coolant sensor is to verify your seeing steady 190* there? Do you have any type of a high idle mod that plugs into the coolant sensor that may be giving you a fit? JR

I believe it became an option for the 00 and up trucks. At least my former 00 had one...It would be very nice to have one on my 98 but I think your right John you would have to have a receiver that is integrated into the vehicle to be able to control the locks and alarm and such. JR

Grinding in 4low is going to happen every time if your sitting still with the truck running. Either need to be rolling along at 2-4 mph, transmission to neutral, shift transfer case directly from high side to 4low, or if your sitting still, shut the truck off, shift t case to 4low, then start the truck back up. Going to 4 high is also best to be rolling gently but can usually be done at a stop also, just don't put the transfer case in neutral. Go right from 2 high to 4 high. If you are experiencing gear clash, it's best to briefly shut the truck off and switch to whatever you neeed. Now as far as intermittent problems with the 4wheel drive, there is a fork on the front axle that slides back and forth to engage the front axles. It is vacuum controlled so make certain the 2 lines going to it are in good condition. They are a combination of rubber and steel lines and run from the fork on the front axle up to the frame, 90 down and along the top of the skid pan and then connect to the top side of the transfer case. You should have vacuum to one of those lines at all times, then when you switch to 4wheel drive the other line should have vacuum. If everything checks out there you may have a fork related issue. It is very simple to remove from the axle and then you can shift back and forth between 4 wheel and 2 wheel drive (truck running) to see if it's actuating properly. JR

What's your first impression on the injectors?JR

Sheesh! I was lucky to scratch 13-14 out of mine. Of course every yota I owned had a minimum of a 4" lift and 33" or larger tires... But yes they are the strongest engine I have ever abused, they gotta rank right up there as one of the best engines ever built. I was out wheelin one night in my 89 with a straight axle swap and 38" Intercos and overheated it to the point the engine actually stalled out. half hour and a gallon of pond water later she cranked right over no questions asked. That engine got so hot it actually warped the hood to the point I had a hell of a time latching it. That night turned a lot of my wheelin buddies into yota believers. That hood hung on the wall in my garage for a long time. JR

A lower end TC is not going to last long behind 700+ft lbs. And without an upgraded valvebody to increase oil flow and the clutch apply pressures your going to be wearing out already tired clutches. Diesels are expensive to own and if your going to mod one, the basics really should be dealt with first or all too often the end result is a broken down truck with lack of funds to fix it... JR

There are several Cummins engines at the plant I work in. A p7100 5.9 in a 25T and a 55T Grove, an 8.3 in a 130T Grove, and 3 shuttlewagons with CR 5.9s. Sometimes they get plugged in in the winter, sometimes they don't. Regardless they almost always get started up, idled long enough to run through a prelim check, and then it's balls to the wall. Same with shutting them down, nobody cares enough to let them idle for a few minutes to cool down. They run em hard at a high idle for hours at a time right to idle then shut em down. I've tried explaining the detrimental effects of running them like this but I honestly don't think these guys believe me because in the case of the cranes that have been around since the late 90s/ early 2000s there has not been one engine related issue with any of them. Never in a million years would I treat my engine that way and whenever I do get in a crane I will go out and start it in advance or give it a few minutes of idle to cool down after running all day, but these engines have been continuously abused and have never missed a tick...yet. They are pretty tough platforms to say the least.

Were you still in Ashtabula COunty Tom?

I think you answered your own question if you read through the entire article. To quote them, "HO models offered higher compression, fuel refinements, and added timing". The added compression (17:1 HO vs 16.3:1 SO) was accomplished with slightly different pistons. There were no changes in the heads. JR
