The 4L80E is controlled by a Transmission Control Module. Full range of travel by the shift lever on the column can't be used unless the shift rod from the column to the transmission is lengthened a bit and maybe bent a bit. The arm on the 4L80E will have to be swapped with the arm originally...

Do the vent test procedures posted above. If it still happens and if running with the tank cap off causes you to drive ok and then start loosing power and top speed progressively. Use a pair of pliers to pull the red clamp up off the hose on the radiator end of the IP. Pull the hose off the...

Good. Accessories turned by the grooves in the serpentine belt with grooved pulleys turn crank shaft direction. Those turned by the smooth side of the belt with smooth pulleys are counter rotating.

I like Permatex Number 2 gasket maker for those plugs. The white tube with the really sticky black goo. Being NPT, they shouldn't need sealant, but as pointed out sometimes they do. I have never used it on my fuel tanks though. Just the gear oil plugs.

Have you pulled the return check valve from the top of the IP to see if the glass ball is covered in little bits of black things? It sounds like you have a fuel system vent issue, however. It could also be an IP issue.

Power steering pumps turn the same direction as the crank shaft on both systems. Only the water pump is backward.

Yep, that is the one. I thought since it was in a flat rate box it was good. So Chris, I have a DS4 core.

Yes Joe, that is the manual for the digital version. Amazingly enough, the post office actually delivered things early yesterday. The analog 480 and the 160 luminosity probe both showed up yesterday afternoon. The power leads were without insulation. Once I replaced that. I put in the probe...

Oh, here is the new ip and injectors last week before I put them in.

The drive went great over there. It attacked the hills with more power than before and did great running around town with Colton. But, since I had retarded the timing since the initial test drive I wrote about above. I didn't have the power I had on that one drive. Then coming home in 93°...

You might find one that hasn't been exposed to engine heat for the past 30 years and isn't ready to crack as soon as you look at it wrong. Chances are low however. If you want to stay all original, then you may go through a few until you find one that holds coolant. JBWeld does fix the...

I went through the exact same thing last month on RED Andy. Under dash relay click, nothing under the hood. Put a meter on the purple wire at the solenoid and power was getting to it. Pull the starter, test it and all good. Put it back on and it worked. Once. Then back to under dash click...

Just remember 4.25-4.8 mpg no matter how you drive with the OA331. At least that has been my experience. Something to keep in mind before you throw the high bid.

I have had the same issues Andy. Just be glad the solenoid is not contacting instead of sticking on.

I have a pulse adaptor for a timing light that works by clamping onto the injector metal line. I have found it has to be on a straight section of line, not even near a bend. How the ground clip is attached and how far from the clamp makes a difference as well. Calling Tiny Tach does seem like...

I have done enough IP replacements that I really wasn't looking forward to the sore arms and shoulders that result from doing one arm pushups for a few hours. So I built up a nice thick row of seat cushions on the valence. It worked great. Except, now my ribs hurt. Oh well, the IP and...

Thank you again for collecting such a good set of injectors Joe. I agree about not being able to do all of this while I built the engine and truck up. However, I couldn't afford to. Plus, I now know more about the way a pump can go bad, ip timing and hopefully, will be able to say how much...

The "boss" or rather dad/owner of the injection place called me last week. He apologized several times that it wasn't done yet. Then he asked me what I meant by "4911 settings" on the ip calibration. I explaned what I had and what it was in. He was kind of hesitant talking until then. Once he...

Yes on the motor mounts.

Yes, the Gen IV sure fit for the non a/c Chevy trucks.
