To close out the question of leaking PF-48 Oil filter: This van went through FOUR oil filters all leaking/loose before one year or an oil change light tripped (generally less than 3000 miles for a leak.) AMSOIL, Wix, AC Delco, brands all leaked. All GM Dealer installed during an oil change or...

It's got 200K on it, PERIOD. At 250K the truck starts to fall apart around the engine. It's frugal to run older vehicles, but, at some point you may want to get it down to two reliable vehicles and spend your time doing something else than major repairs like collectively we do on the 6.5TD rigs...

Watch the return line during the first crank of the day. It can be full of fuel, but, turn to air as the IP gets purged of air during cranking.

Look what showed up in the mail today! Now to figure out doing the actual job of putting them in... The "oil" preservative was a nice touch. Had to look close at these small parts to see the coating.

No. Check the oil level if you suspect something. Simply find where the leak is coming from. Warning high pressure diesel leaking (fine high pressure spray) will puncture your skin and you can loose your hand or die from the injury. Yes it's serious and dangerous. Use cardboard or a broom...

Again as I wrote in post #268: look for bubbles to see what side or both be the problem with T stat crossover removed. Remove valve covers and see if you find the coolant leak plain as day around a stud. We are assuming it's head bolts or gaskets vs. cracked block, cylinder, head. Coolant in...

ATT, CKO HX40II, and something off a 4 banger ... oh wait that's a GM3 Asthma Attack turbo. I believe the ATT kit isn't made anymore. The Mitsubishi TD-07 turbo and knock-offs without mods to fit a 6.5TD still is. It was a hellva stigma to break "use a better bigger turbo" Neither the ATT...

I read combustion pressure in the cooling tank not water in oil. Do you have both problems?

@JiFaire The following thread needs to be a sticky in the technical reference library. I have suggested it before years ago and it was overlooked. It may have just cost Rodd a re-do on the head gaskets. https://www.thetruckstop.us/forum/threads/head-studs-what-will-stop-the-leak.47879/ @Rodd...

If that's the case... that's CAT's disposable engine...

The fun part: The retaining ring requires a special tool, easy to make I read , to install with a press.

Wasn't really looking just checking if it was even available and I tripped over a NOS IP gear. I ordered both gears as NOS as the cam gear is more common to find. Do you coat both gears? Does the coating affect the clearance of the gears? If so I would need to add a shim. Cam gear major...

Can they also run this off the oil pump drive sensor the 1993's had? (And used for the factory ECM controlling the 4L80E) Maybe whatever parts are in the best shape is the question as the oil pump drive sensor would crack the housing. (I sealed mine up with RTV.)

1993 doesn't need it. The water pump, reverse rotation or not, and it's backplate are a different. I have run a 6.2L cover on a 1993. I believe the chain oil splash deflector for the CDR was the only thing I left out of the 6.2 dropped into the 1993 because it wasn't needed. Other than the water...

If it's still a no start... Or the next time it doesn't: Offhand you need 9V at the small wire and 11V at the large wire minimum for the starter to work. Measure with a voltmeter. 9V or more at the small wire eliminates the ignition switch. (With the ign switch in start of course.) Likely the...

Use two exhaust manifold gaskets and header wrap the manifold. Then the 6.2 injectors will work. Not easy to remove, but, will work. This way you have matched injectors IF the 6.2 injectors are good. That's a lot of blowby. Combined with the rear main oil seal leak the engine could have worn...

Ah HAHAHAH, Gasp Choke, Ah HAHAHA!!! I missed this years ago. 🤪 HX40II and ATT with a spool valve in hot AZ heat on a 6.2 longblock... NA small precups and plain non-coated pistons. I ran synthetic engine oil: Otherwise lack of piston coating WILL ruin the engine oil in 1000 miles. (Out of...

Did you replace the HVAC blend doors? Is the fan clutch less than 5 years old and a MOPAR unit? (Not iffy aftermarket or parts store trouble.) Is the compressor turning? If so are the A/C lines at the firewall both getting cold? If you don't have voltage to the compressor coil, not turning...

Common problems: Brake light switch stuck "on". It's not that? Then... Glove box light on. Dome lights on from bad switch. Underhood light. Aftermarket radio gone bad. Or wiring problem. Trailer Brake controller. Horn switch stuck on (relay taking power) and burnt out the horn. And an oddball...

Bad Idea. Good way to experience a diesel engine runaway when the oil flows backwards from the drain into the intake! The turbo flows a lot of oil. Little intake vacuum and you have a flooded Pro-Vent... Take an example from Cummins who uses a separate drain into the block/oil pan from the oil...
