That's what the one I pulled look like at ~200k miles.

Agree'd with everything above. Your trans is fine and the clutch replacement should fix your problems.

But DeCaff2007 said to replace the flywheel as well, I just want to repeat that. Its fairly cheap and since your in there its worth it to know that everything is new and straight. I always consider the flywheel as part of a standard clutch replacement.

I look at it the same way, I always replace the flywheel and the one in the truck now has some pretty significant hotspots. I have a complete clutch kit and flywheel laying around that was installed in my old truck that has right around 1,000 miles on it. I was thinking about using that clutch/flywheel and just buying a new throwout bearing but the old truck had a 5.7L and one thing I noticed is the 4.3L flywheel is much heavier. Is this for balance purposes or? Think it would do any harm if I used the V8 flywheel on a V6?

A heavier flywheel is easier to take off from a stop. The 4.3 makes less torque and you would probably have to ride the clutch more to get going.

That makes sense. Guess it would give me an excuse to yank the 4.3 out and add two more cylinders.

Find yourself a nice, used 8.1L.

Might as well bore and stroke that puppy while you're at it.

Ok am I the only seeing the rear main seal issue here? That's more than just friction disc material. That's oil soaked.

I like the way you think.

Unfortunately gas is $5/gal and I'm already broke daily driving my Volkswagen.

I hear you. I haven’t driven my Suburban since last fall b/c of fuel prices).

But think about this: An 8.1L punched and stroked to 8.6L would give you twice the engine you already have… safe and effective, all in one easy to swallow package.

Yeah it is a bit wet, the oil pan definitely leaks as well but I'm not to keen on putting any money into this truck that I don't have to. I bought this thing for $400 to use temporarily until I finish putting my '95 together. Previous owner hit a deer with this one (the '92) at ~70mph on I-380 and the front end was fubar. I was ready to scrap my old '96 due to extreme rust issues anyways so I pulled the parts I needed and fixed this one before doing so.

Good call.

If there's oil saturating the friction disc - or any other part of the clutch for that matter - a new clutch kit will suffer the same fate, sooner than later.

Now I'm wondering if that's the problem with my own junk. I hope not. I don't want to have to pull the friggen engine this close to being ready for inspection.
