pressure check

[eur04lif3]

I just did a pressure check across all 4 of my cylinders....and i got 90psi for all 4.
I'm fairly knew to cars, only owned this car for 2 months, so i was wondering....it that good or bad? what pressure should i be having?

Also 2 of the 4 spark plugs were oily on the bottom, what can that be?

Any help and advice is appreciated!

cold ? no oil in the cylinders?

well at least the pressure was equal, if you had 3 at 90 and one at 30 Id think you were in big trouble

thats what my initial thought was...but shouldn't i have around 120psi? at least is what im hearing about m50 engines...

what do u mean by "cold"? sorry im pretty new to cars :/
while checking the pressure in each cylinder, i noticed that two of the 4 spark plugs were wet on the bottom, and the other two were dry...i don't know what it means

possibly a valve cover leak; replace the gasket.

or actually the gaskets at the plugs, which come in a it, or individually, but dont get tempted to buy a gaskt for the valve cover without the plug seals,

truth! i forgot to mention those. Most gasket kits will include them or ask if you want them.

Is the engine running? Let it idle for a bit, then check it.


You should have 190+ on all four.
