That they are all similar is of more relevance than the actual PSI measured, unless they are all 0 !
What are the readings on your pots Bumlover ?

here we go...
1 = 177
2 = 173
3 = 148
4 = 120
5 = 170
6 = 175
compression value in lbf/in2

That's shagged. 177 is sort of okayish, 148 is Not Good and 120 is bolloxed.e30bmlover wrote:alright pete?

Ideally they should all be up around the 175 to 200 mark but engines vary greatly.
But as both Pete and Andy have said. If they were all at 170, I wouldn't be too worried but to have a difference of 57psi between readings tells me it's f*cked.
