Is this a blown head gasket?
It has 133,000 miles on it. Problem is it puffs air out of the oil fill when the cap is off, it also has a major miss.
It doesn't have and coolant in the oil or oil in the coolant.
I just got it and haven't had much time to look into it. Could it be a head gasket? Maybe a piston problem, I heard rumor the guy who used to own it used to put junkyard gas in it so it probably had a lot of detonation.
Would this cause air to puff out though?
Tomorrow I guess I'll do a compression check.
