hey yall,

what is a good brand type to buy for a compression tester?

have problems with motor and want to do this one time up from the cyclinder comp test the inj and so on
start up blue white smoke runs ruff , reader says #2 missfire from code and also #8 issue from ford shop guys
have replaced #2 already -2 weeks back to same isssue
replaced all v.c.g's and internal wires

see blue smoke coming from driver side up pipe aswell, leak there too
140k on truck 2nd owner from dealer
also any pic's on test in progress would be helpful
