Very low compression

paulmicin · 03-23-2008, 11:15 PM

i recently bought a 89' turbo and i ran a compression test to find out why its smoking. no. 1 cylinder has 50 psi while the rest are within spec. I poured some oil in no.1 and it jumped to 70 psi so im pretty sure its a bad piston ring. So i was just wondering what are my options. How hard is it to change piston rings myself or how much would a mechanic charge. Also would it just be cheaper to buy a new engine? I can get one for about 1k.
