piston ring condition test

[slider]

can i test condition of the rings by using a compression test ??

this is for a hgt btw

[Teddy]

any lack of compression could be down to other problems though...

[demonfish]

a compression test will only tell you if something is worn...not what is worn

ie low compression - but the low comp could be a slightly bent valve, leaky valve etc.... but 9 out of 10, is something is wrong its rings... so its worth doing.

ok are the instructions usually fairly self explanitory as i haven't done one before?

Spark plug out, compression tester thing in spark plug hole, turn the engine over a couple of times and you should get a reading. Repeat for each cylinder.

unsure if the link works cos my computers too ****ed to open new windows and crashes

too much porn downloading me thinks

it says error 404 or sumink.

my concern re doing the test is the hgt has individual coilpack's and the plugs are about 6 inches into the block

Yea a lot of modern engines have the coilpacks instead of leads and the plugs really far down.

Should be fine with a run of the mill compression tester though.

they aren't too expensive are they?
