Thread: Ok, so I did a compression test!

if i am correct ....valve stem seals would cause gryish color smoke at cold start....after car is warmed up th smoke stops

no guey... pero es q aca hay mas gente q le sabe jajaja es el motor stock nomas q lo traigo amolado y pss pa dejarlo bien!



never had issues with these before... mmm... guess the best thing to do is check everything on the head right?... might have to get another one so i can still use the car

gonna check on the posibility of a leaky inyector or the o2 sensor anyways those are the easiest to do...

Run some seafoam/top end cleaner. Gunked up valves can cause the compression drop. When you add oil to the cylinder and the numbers don't drastically go up, it means it's not the rings.

If you do a leak down test, you can narrow it down even more. Gurgling from the valve cover means valve seals, gurgling from the intake means valves, gurgling from the bottom means rings. (Gurgling or hissing)

BTW I saw my first GSR2000 while visiting San Carlos Sonora yesterday. It was all murdered out and sounded pretty nice.

Leaking injector or faulty o2 sensor will have NOTHING to do with your low compression results for cylinder 1. You definitely need to pull the head to do further investigation. Could be anything from bad headgasket to stuck valves, bad valve seats, seals, or ring issues.

NP = Lamers.....

at the end im taking down the engine so... guess the truth will come at that time....
