Once the truck gets up to operating temperature when it returns to idle the oil pressure will "bobble" at the min oil pressure line. It never does this when it is cold and/or while coming up to operating temperature. When it does this I give it just a little rpm at idle (~900 rpm) and it...

Need to get my converter re-stalled as it is really tight from a previous setup I had on the truck. The new setup is a 64/67/14 over a S475 (1.32 A/R), 5x14's, 181/210, Marine style pistons (about 16:1 compression), and a mildly ported and matched head/manifold. Elevation is about 3000-4000 ft...

Quick question, anybody know if federal emissions laws will not allow swapping a class 2b (6001–8500 lb GVWR) motor into a class 2a (8501–10000 lb GVWR) truck? Was told this was not possible if you need to have your truck smog tested but wanted to make sure. Wanting to swap a 91-94 cummins...

Having some trouble reading the signal from the engine speed sensor to the PCM. Tried reading out DC voltage and frequency...got nothing for the DC voltage and the frequency was not correct at 587 hz (I would think it would be around 25 hz = 750 rpm taking into account the two pips on the...

Does anybody make a manifold that fits a 12 valve with the exhaust foot for the he351 cw and keeps the turbo in the same place as the stock manifold. Looking to change this out with my 64mm high pressure turbo. Thanks Adam

Want to buy a 4" tail section (muffler back) only...used or new (if the price is right)...for a 97' dodge extended cab. Will want the hangers with it. Will get shipped to Tucson AZ...so please try and keep it somewhat close. Let me know what you have and how much. Thanks Adam

Coming home from work tonight my 47re wouldn't downshift into first. Started out in second every time. All other shifts and lockup felt just like normal. Even putting it into first manually it won't downshift. However, going from drive to 2nd it tries to go into first and then right back into...

posting this for my cousin, He just got done installing brand new reman VP44, 90hp injectors, and 165 Air dog set at 15 psi. The problem is when he is coming to a stop light and pushes in the clutch to slow down the motor drops below the normal idle rpm and stumbles until it finally comes back...

Started checking the pop pressure on my injectors with my new tester. Injectors maybe have 3000 miles on them. I only tested the ones from cylinder#1 and #2 but both are cracking open and forming droplets on the bottom of the injector at about 3000 psi (~207 bar). Both were popping (I mean a...

Just finished up my motor and have put 70miles (hard miles) on it to seat the rings but it still has what I would call blow by (i.e. whitish smoke coming out the stock breather vent with the motor running). However when the truck is off and the oil fill in the front is open there is some whitish...

Who sells high pressure oil reliefs (i.e. the one that goes into the oil cooler assembly block)? Thanks Adam

Has anyone built an electric oil priming system that can be used to circulate oil before the motor is started? I was wanting to make one up before I finishing putting my motor back together and thought it would be useful for priming the oil system, for my first initial start, as well as using it...

How far down on the pan are you guys putting the atmospheric turbo's oil drain? Thanks Adam

What is the minimum piston to head clearance? I am around 0.038", is this enough? Piston protrusion from the surface of the block is 0.024" and I have a .010" thicker than stock head gasket. 12 Valve Motor. Thanks Adam

I bought some A1 connecting rod bolts because my old ones were stretching when I was torquing them. My question is, the manual says a final torque spec of 74 ft-lbs, and A1 recommends 90 ft-lbs. So should i torque them to 90 ft-lbs, or will the big end of the rod not be concentric anymore (i.e...

Has anyone every tried to adapt a variable valve timing (electronic type VVT-iE) unit to the p pump? Maybe using the unit made by Denso? DENSO DYNAMICS Adam

Rebuilding the motor on my 97' and when torque the rod bolts from 50 to 73 ft lbs the bolts seem as if they are stretching. They turn about a 1/4 turn from 26 to 50 but from 50 to 73 they turned over half a turn and still didn't make the torque wrench click. Are the rod bolts only supposed to be...

Is it ok to reuse the nuts for my head studs or should I get some new ones? Adam

Pulling the motor to drill the pan for a second oil drain, clean it up and paint it nice, and finally fix some leaks. Questions 1) should I put a new oil pump on it while I have the motor out? 2) What else should be done while I have it out? Thanks Adam
