Occasional rod knock?

I'm tempted to just pull the engine, probably be easier
than pulling the drivers side head in the frame. :mad2:

Probably a good idea, you'd just be mad at yourself after pulling the drivers side head. #6 & #8 are on the pass. side:smile5:

Now there's a point that holds a little weight!

I did head work in truck and it sucks. If you have the means and the know how, I think you already know the answer to your question.

Did a quick look up on Google, it said #1 was front PS,
anyway the rear 2 on DS are low compression, whatever
number they are.
I quit for today, got all the injectors out, lower manifold off,
all the injection lines off, and removed the exhaust crossover.
If I pull the engine, and it just needs a head gasket, I can still
clean it up, change the timing chain and fix the oil leak coming
from the cover - and if it's worse than a head gasket, I'm
ahead of the game with the engine out in the open....
I been looking around, I could put a 383 stroker crate
engine in it for less than a new 6.5, and have more
horsepower and torque, and be more reliable.
The only thing that would be worse would be MPGs
 
I appreciate the words of encouragement. It's not the end of
the world, I guess if you run a 6.5 long enough you can
expect something like this. At least I don't have to pay
someone to work on it.
I would have liked to get another100,000 miles out of it
though. And I don't know yet, it could be as simple as
a head gasket.... Can a head gasket go out, and
put fuel in the oil, without coolant being comprised?
Except for PMDs, it's been relatively trouble free.
The truck is too nice to scrap it, but it's tempting. :D
I see ads for Dodges all the time with 3, 4hundred thousand
miles. Of course I don't know how trouble free those miles were.
I do know that my next truck, unless I get a screamin' deal
on a D'max, will be a Dodge.

Did the cylinders hold the compression?

What recent work was done? Anything with the IP?

I didn't do a leakdown test, just compression.
Only recent work was new injectors, to try to avoid
something like this happening. :sad:
Worst part about this is gonna be using the Jeep as a DD.
I go back to work tomorrow night, probably be Friday
or Saturday before I look at truck again, but I'm bringing the
injectors for the bad cylinders to be tested tomorrow.
 
Thats alot of miles on an injector pump too. Is there anyway the pump itself can breach the oil/fuel seals internally causing excess fuel in oil?

400 - 425# on all except 6 (175#) & 8 (300#)
This is getting ugly :D
Heads gotta come off, best case scenario is a head gasket....
but I doubt it.
Make me an offer, I might bite.... before I pull the head off

I wasn't kidding, just so everyone knows.
Somewhere around 2500 and it could be yours! :D
Probably pulling the engine this weekend, then it's no go
 
Tookie said:
Don't know about that, but I think with 175 PSI on one
cylinder, there's not much doubt about how the fuel got in.

It would take a very long time for one injectors worth of fuel to overfill your crankcase I would think.

Do you still have your heatshield in between the turbo and cylinders 6 & 8?

40 miles wouldn't do it?
I got some bad info in regard to cylinder order, the low readings
apparently are #5 & #7 - rear two on driver side
 
Driver's side head work/removal in the truck isn't that terrible. The passenger side is the one that's a real PITA. Trust me there. I've pulled/installed the passenger side head 4 times on the 94 i'm working on because the company that supplied it can't seem to get it right.
 
Man, I wish a couple of you guys that like to work on these
trucks lived a little closer to me! :D
Wouldn't be as bad if I had my shop built already, I am
working on a crushed concrete (gravel) drive, in the open.
Gonna have to build a mat from 2X8s for the engine hoist
to roll on. I'm only 30 minutes away from having DS head off,
if nothing goes wrong, so I'll probably pull that Saturday,
and see how bad it is.
Do y'all manhandle these heads into place, or use a hoist?
What are they, around 120# each?
 
I've always lifted them off. Engine in the truck, it's much harder than with the engine on a stand IMO. They weigh a ton, numbers don't matter really. I know the box from clearwater said "Heavy package over 70 lbs". How far over 70 lbs i don't know.

I've never used a hoist to lift heads, but between myself and my friend that i do car work with we carried a complete Honda 1.6 engine across the street to the car it was to go in. Guess you could say we are a little nuts. ):h
