    I am going to be doing a complete fluid change on my 01. I am looking for a recommendations on what fluid you guys are running or what works best in these 24 valves. I will be doing coolant, engine oil, atf fluid, and rear diff. Should I run any additives? Manual says to run something in the rear diff. Truck has a little over 80,000 miles on it and is an auto trans. It is a tow rig 75% of the time but not a daily driver. Looking for good quality stuff that is affordable and readily available. Is there anything else I need to do while I am doing all this??

    Alright so I was curious as to know what that meant, to over spin a turbo. Well, I dunno if my circumstances will make that an instance or not. But looking it up, I found this: I have seen more than once, our trucks produce a puff of smoke. Sometimes my smoke is white, sometimes black. I just associated it with the diesel. But then again, how relevant is this to us? Makes me wonder if I have overspun or of the previous owners have overspun the turbo?

    They are convenient at times, but while towing I find myself under throttling to keep it from kicking down a gear. I like to lug a bit, but give it a little more pedal and verooooom she kicks into a higher gear. Since Trans swaps are expensive and time consuming. Is there any kind of mod that can be done to go through the gears manually? I don't even know what wide open throttle is. If I go that far it will go into a lower gear and rev up like crazy.

    Alright, someone please tell me this is about normal? I switched to Amsoil on my last oil change. I'm now about 4300 miles into it, and I checked the oil level recently before I went down to see my parents for christmas. Its a good thing I checked! The level was below the add mark and I had 2 quarts left of this liquid gold to add back into the safe area. I noticed the oil pressure gauge showed a little bit longer of a delay in building pressure on initial startup and pressure was a little lower than normal. Nothing that raised a red flag, but now I know why it was so. I have noticed since the change that the blowby vapor looks as though it has increased and there is …

    I asked this before...but after 6 months of 2 cycle oil use I've still got ticking going on. Sound comes out of both front wheel wells. No difference one side to the other. I try to listen to other 24 valve rigs out there and some have the clicking sound and others don't. I adjusted my valves, but should probably look at them again. Maybe one was way out and I adjusted at 20 rather than 10? Other than excessive lifter noise, could a bad injector cause the sound? Idle is smooth, but power and torque seems lower than I feel should be, but that's not backed up with any kind of inpherical evedence. Oil pressure good, fuel pressure optimum, fuel economy around 14 when towing a…

    I recently installed an edge insight with the expandable egt harness. I was looking at adding lift pump pressure, but by the time I buy the sensor adapter with the proprietary connector and their pressure sender I'm looking at almost $300. Has anyone found an off the shelf sender that will work with the insight? $100+ seems awful steep to me.

    Damn. Recently pressurewashed and thoroughly degreased my engine. Yea, I know once the engine is squeaky clean this the best way to spot leaks. So, I have an oil leak where the vac pump / ps pump flange mounts to the rear of the timing case. Dammit! Hard to get to. Has anyone taken this assembly off to change the gasket & resolve an oil leak? My first gen has a leak in the SAME EXACT area. I tried to remove the assy on that truck and ended up frustated. I'm not fixing this issue on the old first gen, but my 02 is one sweet truck so I'm inclined to fix and keep it clean. Any tips or step by steps? Picture attached. (picture taken while i was …

    Ok, the other day I changed the oil and filter and every other oil change I change the fuel filter. This time I notice a litte dirt inside the housing so I drain the housing and clean out the dirt. It was cold out so I left the fuel bowl empty. In the past I've just filled it up to the top of fuel stem and rolled the key a couple of times and it would start. I forgot to fill the fuel bowl back up today and just rolled the key, and now it won't start. Pulled the filter and the bowl has fuel but it won't fire. I seen an article on here before about loosening fuel lines in a certain order but cannot find it. A little help would be appreciated.........

    Around 2000 rpm upon acceleration it sounds like I have a boost leak coming from the back of the engine in the center of my dash. The head gasket isn't noticeably leaking anywhere and my coolant level is good. I replaced the intake horn gaskets, intake manifold gasket and put new intercooler boots on. I'm thinking the head is lifting, due in part because I swapped my HY35 for WH1C with an aftermarket wastegate set at 35 psi. And no gauges...yet...maybe it's just more air sound I don't know, wastegate?. Any thoughts?

    Not too worried in fact I kind of like it but I'm wondering what causes my problem. My TC doesn't unlock when I let off the throttle. Go on the brakes and it works OK. when it gets down to about 20mph (in 3rd) it unlocks by itself and sometimes if I blip the throttle it will unlock. It's like having a free ATS Copilot. It did this awhile ago and then cleared up for a year and now it's back. Shifts fine otherwise. I'm thinking APPS or something throttle related. Any idea's?

    I was on my way to vist my brother today and while accelerating the clutch slipped in 5th. I realized my toe was on the clutch pedal and removed it right away and let off the throttle. Got back in the throttle(about 75%) and it slipped again. Did this 3 times in a row. Got done with my visit and took off to my daughter house. I had to drive across the mountains from Hickory nc to Johnson city Tn and never slipped the clutch once and I was trying to. The valair clutch is about 2.5 years old with about 65k on it. Anybody ever had this happen to them? It was strange,

    My truck usually fires right up '99 4x4. 160k miles It started cranking longer a while back, but if I turn the ignition on and wait a few seconds for the lift pump to start it will fire right up I thought it was the fuel filter heater grommet Oring(stock fuel filter). slight seegage Well I finally resealed the grommet. But I still get long cranking if I jump right in and try and start, unless Im patient and wait a few seconds for the lift pump to run then it starts right up. Went over the whole truck fuel fittings checking for leak/seepage, top fuel tank etc. Everything looks clean and no sign of leaks Truck is stock, has all gauges, fuel press, boost, t…

    I have a 2001 Dodge Ram diesel 4x4 that has developed a transmission fluid leak at the transmission cooler line to hose "quick disconnect" connection, once I finally got the connection apart, there is an o-ring inside the hose side connector. Is the o-ring available and where? Anyone have the part number for the hose line with the connector, I have searched and cannot find a part number. I prefer a good quality part, as it is very difficult to get to the trans cooler end and I don't want to have to replace it again. There are two hoses and I can't remember now which one I need, I think it is the hose closest to the driver side, but if I had both part numbers I could fig…

    I replaced my water pump last year. It is leaking out of the weep hole again. The thing is when I was trying to check I didn't see anything come out of the weep hole. I could see where it had leaked out of it, there was evidence of it at the weep hole. There Is antifreeze under the pump that pooled there. But when I get the truck to temp and watch it I never saw any leak.Would the pump just leak intermittently? It just seems to me if it is going bad it would leak all the time. Is there anything else that would cause it to leak from the weep hole besides the pump goin bad?My truck is a 2002 6 speed 4x4 Thanks to anyone that can helpJason

    I can't find my earlier posts on this... Every once in a while, the truck would not more than grunt. I'm only using it intermittently every couple of weeks. I have a 1.8A solar trickler on the dash into the always on lighter plug. The thing is, a hour on charge or a jump will fire it right up. The batteries don't seem to take much charging to spin it over. My first thought is dirty connections. We caught a nice warm day yesterday & I cleaned all the battery terminals with wire brushes. They weren't really bad as I have the treated felt washers under them all. I did see a spot on one that just looked a bit oxidized. I found one terminal (Pos on Driver's…

    When I tried to start my truck this morning the WTS was flashing. The truck will crank but will not start. I think it may be the ECM. The fuel pump will not run when i bump the starter, but will work off the battery on a switch. I have checked all relays, fuses and battery connections. There are three codes P0123, P17656, P1694. Does anyone have any ideas what else I can check?
