Be aware a bad oil pressure sensor can foul the MAP sensor. This is a little secret from another member.

Ummm... P0216 code could be... If the timing piston is galled up and damaged there is no real electronic issue with the PSG but the timing piston can be jamming up because of expanding metal as the pump heat up it starts to jam and stick. Then when the ECM calls for advancement or retard the timing doesn't respond fast enough because the piston is stuck so the P0216 code is thrown.

44mV AC is borderline. (50 mV random problems start - 100mV is a fail.) 26mV AC is normal. (20 to 30mV) Now if you did the W-T ground mod it will drop even lower. Be warned do not do the ground mod to cover up bad diodes. Replace the diodes first or replace the alternator before doing the ground mod.

I'm not sure if the timing was the whole problem. I started having coolant leaks on the back of the passenger side of the head. No freeze plug issues. All head gasket. Now talking to local friends they informed me that 300k mark typically head gaskets start to show up. Like even Justin, down at Northwest Machine said the same thing 300k is like the end of the head gasket life and the head start to curl in the back and front. All right here...

In a nutshell all local driving still highway but limited to 55 MPH. Chevron Diesel fuel only. Be careful. Cetane is backwards to what you think. There is no benefit to using a higher cetane number fuel than is specified by the engine's manufacturer. The ASTM Standard Specification for Diesel Fuel Oils (D-975) states, "The cetane number requirements depend on engine design, size, nature of speed and load variations, and on starting and atmospheric conditions. Increase in cetane number over values actually required does not materially improve engine performance. Accordingly, the cetane number specified should be as low as possible to ensure maximum fuel availability." So where the lines cross is the cetane number but notice the BTU number of the higher cetane. This is why winterized fuel of 45 and up tends to produce less power and lower MPG's. Again this is all quoted from the ASTM test labs documents. I actually look for 40 cetane where I can the lower the better. This is why 2 cycle oil was a good part of the high mark too since 2 cycle oil reduced cetane more.

Being the Cummins is shredded in the shop I've been driving the 96 Dodge half ton. I love these 215's tires on this truck awesome performance. With the 46RE transmission having a tall overdrive gear you still find that you are grabbing the OD Off button in some areas. It pulls up the power great and backs off on the cruise again. Last tank I still hit 16.34 MPG even with hopping on the interstate and running 70 MPH to Boise to drop the head off in the shop. I could of pulled a bit better numbers if I was stuck in traffic and stop and go. Oh well... Still not complaining this is awesome looking back at the old numbers of 12 to 14 MPG it a good increase in power and economy.

Correct. But you might add just a touch more to them. When you are running a lot of timing there is more flame on the valves and the do expand a bit more. Remember stock ECM the timing dives out to about 12 to 14 degree range. Like myself in the 19 to 21 degree range. EGT's are much lower, boost is lower, but ECT is higher. This means more expansion of gases are working on the piston, cylinder head and cylinder walls. Might be part of my reason for head gasket failure. Well, I've got ARP studs coming.

Fluid level should be checked hot like 140F or better.

Basically you need to spend roughly 100 dollars for good meter that has 2V or 20mV setting on AC side.

Delivered...

Like I'm learning from this app I can safely now drop from 91 octane to 89 octane and not lose MPG but also still no knock or ping issues. The cost per mile is now down to 20 cent per mile on the 1996 Dodge and still able to shave a bit more off. I miss quoted the Cummins its actually 17 cents a mile so I'm close.

Like I said I was looking for commonplace fluids. Works out to $12.54 a quart. https://www.napaonline.com/en/p/VAA706035M Much cheaper than the OEM Mopar at $27 a quart. Which is no longer manufactured.

I'll mention @Dynamic name maybe he has feedback on this issue.

So what I would do is unhook the Quadzilla completely for a test and clear the codes and go for a drive for 10 to 20 miles and then check for codes again. If the codes are gone then the Quadzilla is at fault with a boost fooler issue. If the code returns the MAP sensor or wiring on the stock side is at fault.

Your wish is my command... This is a 2002 I'm not sure what your you have...

Welcome to the site... Hopefully we can get you the help you need and keep you moving forward.

Wish a had a little car for stuff like that but still come winter time I'm going to need the Cummins to run the 250 mile round trip for MoparMom's dialysis. So now that I've been investing effort into the little 96 Dodge I'm managed to reduce it operational cost considerable. Last two tanks are 20 cents a mile to operate. The Cummins still the winner at 16 cents a mile even though the price of diesel is more than gas. Just don't have the means to pay for another small vehicle, insurance, and registration. Being all I can do right now is work 2 days a week Wednesday and Friday. Being Tuesday, Thursday and Saturday I drive 13 hours for MoparMom's dialysis. Not many want to hire me for just 2 days a week. That leaves me doing odd jobs. Since the entire canyon was on fire and people more worried about the fire all my summer income (A/C work) never happened so I'm on a very tight budget. I've got a few tidbits of income but man this whole head gasket thing sure screw my budget up. I do have fall back savings so I'll be able to do the repair, just my personal needs are on hold until the funds are returned.

Awesome rides. Wow you need to add those to the Garage area... I'd love to see your current Cummins truck.

Nope, not happening... Not on my budget. Might be spending $1,000 to $1,800 just get the head to functional state. Then you figure I just spent $950 in tires just the week before.

Heck, you've not even done the first oil change yet have you?

Same here with my 31 foot. One main slide and lot of air space. Now back in the day doing my canopy camping. It only took one body in the back of the truck and the moisture would build so bad that you would have rain in the morning would you rolled over or got up.

Head is going to get packed up today so Tuesday trip down I'm going to drop the head off for rework. I'll keep you all posted.

Got you covered...

While I was getting the last few sensors out of the head and getting it cleaned up to load in the back of the 96 Dodge for its trip to Caldwell on Tuesday. I notice something and found out why my oil smoke on startup was occurring.

Still losing ground... Telsa over priced? https://www.theregister.co.uk/2017/12/01/germany_removes_purchase_incentive_for_model_s/ Then easy to steal? https://www.theregister.co.uk/2018/09/12/tesla_hack/
