Out the oil cap? The oil cap should be tightly sealed. Are you sure the PCV system is working? The bores do not look spectacular in the photos, but it may be hard to see. If it was a head gasket, you would hear exhaust noise with the oil cap off.

Have you actually gone and given it a proper drive? EGTs over 1100 F?

While the head is off check the piston protrusion on all 4 just to make sure there rods are all straight.

Had it out for about 15 miles. Was able to get egt up to about 850. Yes, even with oil cap secured I get smoke past filler cap and if I disconnect the pcv from air filter I get the same smoke. I do think bores are a little shiny.

Well, the PCV system should make a big difference, so it sounds plugged. Check it out. The filler cap should be air tight, so it needs replacing. In a well loved engine, you can still see the honing even at high miles.

850 is not even warm. It is not hot enough to clear up any coke from the rings. Really best to see it over 1100 for a nice period of time.

If you have valve stem seals pushed up (per pm) it sounds like you need a valve job. I wouldn't suspect the rings first. Having a valve job done is fairly cheap <$200.
That said its a diesel and yours is a drafty military truck, you are always going to be able to smell it.
As John says 850 is low- cruising @ 55mph on level ground kind of temp.

Leaning towards getting the head sorted (its needed regardless), then install and see where I am at. If I am still loosing compression it will confirm rings and I will go down that road (later).

Machine shop provided same recommendation as above with taking care of head and see how lower end pans out. Great shop in Stafford va, looks and sound (reviews) to do good work.


Just heads up.. if purchasing a used motor its ideal to be in person when its run, not just a provided you tube video. Could have spotted some of the above warning signs instead of taking someone's word.


This was sold as "No problems with it" but.. I purchased a used motor.. New turbo$$ rebuilt head$$ possible rebore in near future$$


Learning has occurred

Can not possibly agree more.

Folks need to understand that these engines in unknown condition are not worth much.

I hate to say this but I have a problem with my rebuilt 4.6L for my disco2 from RoverlandParts.com about 5 months ago.


Rebuilt doesn't mean much I have learned, you are still taking another person's claim on it.

what has been their demeanor like when you told them their engine is not meeting expectations?

So apparently leaving the top bolt out of TC has the same symptoms as intermediate shafts oring failure.

Started removing drive shafts and shifter linkage to pull transfer case and noticed no bolt in the top hole above intermediate shaft(open to inside of case).

I didn't have any bolts left over but forgot the last transfer case had a stud in this location. So tc leak should be resolved.

Got the injectors tested today. Tested fine. Shop is a bosh and garrett dealer. 40$ and he threw in brass seals for injectors and spill line.

Machine shop did great work reassembling and going back in this evening. Cost me $225 for the valve job and skim with pressure check.

Head back on. Compression test done cold.

Probably improve a little once warmed up

Need a thermostat housing to head gasket then ready for drive.

Nice!!!

I think I am going to get the head done as well. My engine is on the engine stand and I already have the manifolds off.

Now, how do you do a compression test on the diesel engine?

Did they replace the valve seals as well?

Go to harbor freight. 25-30$ kit. It has the adapter you screw into the glow plug hole. Disconnect wire from back of IP. Turn engine over about 5 or 6 times to let pressure max out. record, move to next cylinder.


Yes the majority of the seals had lifted, for the price, might as well have the valves done and a skim while head is off.


Read my post further up about the flywheel housing gasket. Use the good one the first time!

Told ya.

Your numbers are low but within appx 10% ( ideal is within 10 lbs of one another) which is whats important. I'd suspect the HF gauge is just reading low.

I know I have a feeling mine may not be even like yours because I tried spinning mine a few times. Maybe 3~5 rev and there is only some high compression/resistant section of those rotations.

Thanks for the heada up on the gasket.

Did you start the engine? Did they check the fuel injs?
