just bought a super dupra, noob to the car

C1: 160psi
C2: 158psi
C3: ???
C4: 162psi
C5: 156psi
C6: 163psi

we arent real sure about C3 we got psi numbers consistent with a freightliner truck so im in the process of rechecking that one, there was some oil in the valley between the cams that the spark plugs sit in, does that mean anything?

freightliner truck? what does that mean? very high psi or very low?

the other numbers seem good, fairly consistant.

the oil between the cam towers is either the valve covers or cam tower gaskets leaking, a pretty common issiue with these engines after so many years/miles.

the numbers are extremely high i the highest reading we got was a little over 210psi

210 isn't outrageous, but it is a little suspicious. more than likely there is oil sitting utop the cylinder, either caused by bad rings on that piston, leaky valve stem seals or worn valve guides.

was the spark plug in that cylinder kind of oily?

ther was no spark plug in the number 3 cylinder

OY...

this whole situation is a big headache for me just trying to understand wtf is going on here.

so no spark plug, doesn't mean it exploded, just means that someone is an assclown, removed it and didn't put it back... OR... didn't tighten it and the compression blew it out of the cylinder when someone tried to start the engine.

a head ache for you? you dont even own the damn thing!! imagine how I feel!

anyway, the compression didnt blow it out there is no scaring at all to threading, so far everybody is telling me that the sparkplug detonated when the timing belt blew, but those two things arent neccesarily connected to eachother, i think it was just bad timing*no pun intended*
