ve L98 compression test

[vr304]

Hi guys as the title of the thread suggests did a comp test on my L98 and came up with the following, any opinions on these figures good or bad?
1 - 163 psi 2 - 186 psi
3 - 176 psi 4 - 186 psi
5 - 189 psi 6 - 180 psi
7 - 180 psi 8 - 173 psi

Number 1 isn't great.

They should all be within 10% of each other which 1 isn't.

Was this a dry or wet test?

Dry test mate, might be worth doing a wet test huh

I would then compare results.

Last comp test I did on mine was IIRC between 190 and 195 dry on all cyls except one which had no compression.

except one which had no compression

That was the one with the broken valve spring?

Yeah.

So an update on this I now realise I did it wrong the 1st time, I only had removed the spark plug on cylinder 1 when I did that cylinder I tried it again today with all the plugs out and on number one with 7-8 cranks it jumped up to 180psi with 6 cranks 175 and number 3 with 6 cranks went to 175 number 5 went to 185
didnt bother carrying on after that as I’m satisfied my engine is in fact healthier than I originally thought from the 1st lot of compression tests
