I recently bought this car, it had been stored for 6 years. When I got it home I cleaned out the fuel tank and put fresh gas in it but still idles very rough and has a tremendous amount of blowby. I did a compression test and have even numbers on 3 cylinders(about 125 psi) and one at 60. I'm hoping it just has stuck rings but don't think thats the case. Probably changing rings if not piston. I doubt oil was put in cylinders before started after storage. In your expert opinion, do you think it needs rings or can I try driving them free, also going to try Marvel Mystery oil soak to free them. Thank you
have the same problem?
