hi ya
was the test done wet or dry ,cold engine or warm ,all plugs out with fully open throttle
anymore than 10psi differance is not good may be rings or bores ,if test was done warm and wet looks like engine out time

yes i done it with the trottle wide open all plugs out, i didnt realy warm it up, well i had it ticking over for about 5 mins then relised i left the compression tester up my house so i knocked it off. it took my about 15 20mins to return before putting the tester on it, should i have warmed it up to normal temp first?

i was told the other day in a thread but my computer keeps fucking up all the time so can get to them

How many times did you repeat the test?

And did you do a leak-down test or just a pressure test?
