Compression

[PaulGTIR]

Hi carried out a compression test on my engine it's pretty much standard apart from it has a hks headgasket 1.2 mm

Cylinder number 1 =132 psi
Cylinder number 2 =130
cylinder number 3 = 132
cylinder number 4 = 143 psi

What do people think of these figures??
Thanks

Very low mate, mine were around 12 bar each on a cold engine, i think 10bar+ is more normal.I'd expect lower figures with a 2mm HG but not a 1.2mm.

Depend's on how accurate your compression tester is,how good your battery is,did you use w.o.t? on compression test

My battery wasn't the best but carried out test when engine was stone cold on full throttle what does W.O.T mean?

And the compression tester I used is probley not the mist accurate due to being quite old
Thanks

Wide open throttle= w.o.t, do the test on a hot engine,wot ,all the plugs out and a good fresh battery,otherwise your results arn't worth a toss
