ok guys i have a huge problem i was driving last night just for fun and i came off of a light and stepped on it. The car studdered a little bit then gave a huge backfire and barely idled, smoked like hell, and ran like ****. so i drove it home and did a compression check first i have 150 in no.1, 120 in no.2, 60 in no.3, and 0 on no.4. What would be the problem piston rings? valves. It never jumped timing i checked that. What should i do? Anything would be great thanks.

 

hey its me again the car is an ls turbo b18a with 8 psi.

 

well if you have no compression, leak down is the next likely, but with it that bad, if the initial timming is on, id just yuck it up and pull the head.
