Compression test help
I have a blacktop sr20 (I believe it's stock as that's what I was told) the car never gets driven as it's a project car.
Anyways i live in jersey and its been sub 30 degree weather lately. I decided to do a compression test to have an idea of how healthy the engine is. Well I'm a bit thrown off and confused.
Compression test cold
1 - 124 psi
2 - 119 psi
3 - 125 psi
4 - 125 psi
Now I also decided to do a warm test (this is where I'm confused) the compression numbers are very similar to the cold test. So I decided to put some oil in each cylinder to see if the numbers jump.
1 - 150 psi
2 - 145 psi
3 - 150 psi
4 - 150 psi
Now I know that when the compression numbers jump it usually means bad rings, however I'm confused as to why the compression remained the same between cold and warm. 🤔 Maybe I didn't wait long enough for the engine to warm up?
no prior symptoms no lack of power or anything to have me question the compression I did it just so I know where I'm at.
Any input is appreciated 😬
