Well I think it happened, got 0 pressure on the #4 cylinder. I'm thinking of replacing the whole motor with a new crate motor. But with all the extras already done( head studs, egr delete, oil cooler) the problem is I'm having a hard time finding any kind of literature that will guide me through the replacement. Any suggestions

 

Howdy,


Welcome aboard!

Well, Not much info to go on.

How many miles on the engine?, was there an "Event" that would suggest catastrophic failure? How was it running before all this happened, how many miles, temp, oil press, HPOP pressure, etc etc......

Now having said that, If it were me, I would pull the engine and remove the heads (at least) to have a look.


Regards,



Rick

 

0 pressure would indicate an extremely severe failure, like the piston failed at the wrist pin or the rod is no longer connected to the crank shaft. Even so, it's worth at least a partial tear down to inspect it before ordering a whole new engine. What kind of instructions are you looking for? Engine disassembly or engine replacement? We have threads here in the 6.0 section for both and some of them have some pretty decent pictures. Try the Search feature at the top of the page. Welcome to FTE and good luck with the truck!

 

Please define 0 pressure. 0 compression would be a home on the piston or similar. I would think you would hear a rattle and knock. I wouldn't think a missing head gasket would result in 0 compression.

How was it measured?

The bottom end of these engines are very robust.

 

One very useful tool when it comes to engine
health is a leak-down tester.
The big difference between gas and diesel is
how you get the air in. With Diesel you don't
have a spark plug. The easy way is to use the
glow plug hole and an adaptor so you can mate
the line to the hold. Also they say to check the
coolant for bubbles and I would also pop the fuel
filter cap and watch there also.








Here is a how to make a DIY one your self.

I was pulling a boat back from the lake, all the sudden a cloud of white smoke and a vibration from the motor, like an idiot I thought I could limp in the last 15 miles. Then a big puff of white smoke and she died. Took the truck to a mechanic and he informed me of the 0 compression. I don't know what or how he did the test. Temp and oil pressure were all good at the time of death. I've read that in order to pull the motor I have to pull the cab off. Is this true

 

It's possible to pull the engine out of the front without pulling the cab, but a good shop with a lift is likely to pull the cab. It can save time and make the job easier (possibly less $$) even though it sounds expensive. And again 0 compression sounds a little suspicious to me, a piston with a hole in it will still make a few pounds of pressure.

Here's a fairly recent thread with some good engine pictures and toward the end are pictures of the engine going in with the cab on.

I just finished rebuilding my engine, you don't have to pull the cab. In fact, it isn't that bad of a job. You don't even have to take the hood off. When I put it back in, it was about 20 minutes from the time I rolled it forward until I had a couple of bolts in the tranny. Yes, I got lucky, but it really isn't that bad. There are 8 motor mount bolts, they come off in minues with a ratchet. Bellhousing bolts are all easy to get at (take the tranny dipstick tube out first), rad support comes out easy... it's really not that bad. The only things that made me take the Lords name in vain were the converter nuts and the y-pipe. When I put it back together, I cut the end off of a wrecked 6" extension and welded it to my 9/16's socket so I had the right depth to get the nuts. (There are 6 of them). And as far as the y-pipe goes... I got it on the 3rd try with a crowbar beating it into place. (Use anti-seize on the clamp)
There are lots of us on here who would be willing to help you. Search "engine removal pics" and look at Anthony's pics. (It'll show up on the 3rd page, what a search engine we have on here )
