Don't know exactly - but north of 175 psi. Take out all plugs. Crank on each cylinder with the tester installed, let it pulse 4 times. you should not see a variation of more than 10% hole to hole.I didn't notice any chunks hanging around in the cylinder with the bore scope. There was small pock marks on top of the piston and some carbon flakes I believe. What should cranking compression be and do I just remove that plug for the compression test ?
Sorry have been busy, I checked the cylinder and looked good with bore scope. The timing was way too far advanced, the tbi computer was putting it way out of spec. I got the timing right and all is good, plug looks good and no misfires@Cdog_96 any updates?
@Cdog_96 Glad it's running good now.
Just to say it, while setting the timing are you disconnecting the wire by the harness bulkhead connector down below the wiper motor / master cylinder? (I think it's tan /white the connector below wiper motor is what I was disconnecting
I'm not an engine builder, but I am not sure how the timing being off will smash a plug like that.
