How would I go about checking my compression on my motor? I did a motor swap in my 97 Prelude, cause I hydrolocked my last one, and I just wanna make sure I'm running the right compression with this new motor. To me, this motor doesn't seem to be running like it should....Also, how can I tell if my timing is right?

Thanks

 

Compression tester screws into you spark plug port, has a gauge on it. Timing light hooks up to your spark plug wire, flases on you pulleys so you can see the marks.

 

so what kind of numbers should I have???

Thanks

 

around 200-210 i would think

 

Mine has 210 in all 4. The testers aren't 100% accurate so they very. The one from sears is usually higher than the one from NAPA. Typical numbers are anywhere from 180 to 220.

 

Thanks alot guys...I'm going to use my friends tester whenever I get a chance

 

Pull your injector fuse prior to testing, and test compression at WOT. Otherwise you'll get low numbers and will have a stress attack.

 

i was wondering if you need to pull all the spark plugs or just one at a time when doing a compression check
