The pickup has the 5.7L and about 163K miles. It needs tires, has just a little rust, but otherwise isn't too bad. It's also an extended cab 4x4, which is more desirable around here. It doesn't leak anywhere.
It has started to miss a lot in the last couple weeks. Sometimes (after it warms up) the miss isn't bad and it runs almost normal. Other times it misses bad.
I've narrowed it down to one cylinder (2nd from front on the drivers side). Compression test shows 20-25psi at idle max 90psi when revving slightly.
I'm trying to figure out it it's valves or rings. I squirted some clean oil into the cylinder and that didn't really change anything.
Any ideas ? If it's rings, I'll probably sell it for whatever I can get for it, since that's going to take some cash to fix. It would only be worth $2000 if I fixed it anyway. I really don't need it anymore (but I will miss it for mostly sentimental reasons because I like the roomy cab).
Thanks in advance.
