[Vwdiesel] low compression

[Kenneth E. Oldrid]

I have a question regarding my 86 jetta 1.6 NA, 250k. The engine just stopped
working last fall, would not start. Compression test yeilded following values
in psi: 220, 350, 150, 240. I believe all values are supposed to be around 395
give or take 20%. So I removed the head, which looks great by the way, and
measured the bore of 2 cylinders, and they were out of round by .1mm, more than
the allowed .03mm. I'm wondering what my options are to bring it back to life.
How much would a machine shop charge to bore out a block? I would have to buy
oversized pistons and rings for this, correct? Could I get away with installing
new rings without replacing pistons or boring out the block? WHat do you guys
do in this situation? Everything else on the engine seems to be fine.
thanks,
Ken
