just fitted the new cam and did a compression test

no1 140psi
no2 140psi
no3 120psi
no4 120psi


at first no 3 and 4 were only showing 90psi,but after starting it for 30 secs and then doing another comp test it gave the above results.whilst running i pulled no 4 lead and it made a massive difference and same with no3.

so it looks like i may have been lucky,although it does sound a bit tappy,

ill build it all up tomorrow and take it out for a little run.

 

you were lucky mate...very lucky mate.

 

i hope so

 

Why a 20 psi difference from 1 and 2 to 3 and 4. Does this point towards a further problem?

 

what engine

Cheers

possibly,but a much better result than i expected

 

As long as its better than expected then good
