Just over 200k miles my compression is between 121 and 126 in all 4 cyilenders.....is this bad? I read its supposed to be 135 to 175...

 

As long as they're all the same it's good. Expect a little compression leak @ 200k miles due to warn parts. I'd also try a different compression tester as well just in case.

 

thats a bit low but as long as theyre all close you wont get any drivability issues. Was the engine at operating temp when you tested it?

 

i drove it about 2 miles to the orileys , it was a cold day.. the spark plugs were ouchie.. lol.. im just trying to deceide when i should change out my motor... maybe i can pull another 50k miles out of it.. new timing belt and water pump and tensioner....

 

Also...did you 'floor' the gas pedal and leave it floored while cranking the car when compression testing? I remember not doing this once and I got really low numbers.

 

no i dident at all, i just turned it over for about 6 second... actualy to be honest im trying to deceide if i need a motor or if it can wait cuz its either buy motor or buy ksport coilovers lol

 

LOL!! So you didn't even properly test your compression. This is what I normally do:

1) Remove ECU fuse
2) Remove all spark plugs
3) Screw in compression tester
4) Floor gas pedal and keep it floored for the duration of the test
5) Turn key and crank motor, I normally count about 10-12 cranks per cylinder

 

yeah i guess not, im still new to all this stuff.. haha.. but im learning... thank you. ill try this tomarrow and get back to you with the resluts
