Hey everyone..so i did compression test on my car and here are the results...
1st cylinder 180 psi
2nd cylinder 210 psi
3rd cylinder 210 psi
4th cylinder 209 psi

So i was wondering if there is any way i can pinpoint what exactly is going wrong with cylinder 1..is there any way i can tell if it's the rings or valves or gasket without taking the engine apart??

Thanks for the help

 

Yank the number one plug and shoot some thick oil into the cylinder. Quickly retest the compression. If the numbers go up you have a ring issue, if they stay the same it's valve related.

so how much oil should i dump into the motor?? and i dump it into the spark plug hole right after the spark plugs removed

 

okay found out i have a ring issue. Thanks for the help

 

Dude, that's not bad unless you have major blow-by or get bad fuel mileage. Unless you plan on a rebuild anyways, I'd leave it as is for now...

 

just testing my signature

If it more than 13 psi difference is only going to get worse. Rebuild it you'll be happier in the morning.
