Compression Test:

170/175/175/170

Leak Down:

30/30/30/20


The car has been sitting for the good part of almost 2 years. It is turned on roughly once a month and driven even less.

So, I've been doing my research and I have heard that 20% leak down is marginal, and anything above 20% is a definite warning sign for trouble.

What should my expectations be for the motor at this point as far as how long is it going to last me? Are there ways to salvage what's left of the motor/prolong its life?

i wouldn't say its a huge issue, as our cars tends to have small leaks. the only thing that would be a huge issues is the head gasket (500$ish replacement if sum1 does it for u) DIY for 100$ish

depends how u drive it, compression is still good, headgasket cant be bad.

even my 5s-gte after less than 500 km 190/190/195/190 , 25/25/25/25

those are good compression numbers... is the leakdown cylinder leakage i suppose?

I'm not sure, I'm planning on having another shop do another leak down and see if they can pin-point where the leak is coming from.

The compression numbers are quite close which is a good thing. As far as leak down, no motor has a perfect seal and like you said 20 is marginal.
