just bought a super dupra, noob to the car

Why are you assuming it is a spark plug now? And an exploding one at that? It seems you were spoon fed a buttload of misinformation and are now trying to work around that.

Nuke all that crap from your mind right now. Go pick up a Haynes or Chilton's manual for the Supra and start reading. Serious.

It's probably something really dumb like a forgotten ground wire, or hell, maybe they didn't put the timing belt on right and it's timed incorrect. At any rate you need to rediagnose the car yourself.

When you turn the key on and then crank it, what does it do? Are there any knocking or tapping noises coming from the engine? Does it spin over fast or normal?

Need YOUR diagnosis, not that silly lady and he half-wit mechanic's.

i really have no idea where i got the spark plug thing from i guerss i just mis read what you wrote.

i do have the haynes manual and i have read almost the whole thing, that doesnt mean i know what happened to the car

the battery is as dead as a door nail, NOTHING cranks up

[Supra Goddess]

step 1. replace battery
step 2. turn the key over, crank it and see what happens (and listen to hear any knocking)

you're obviously smart enough to run a compression test. what were the numbers?

[bleSId]

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?

[Supra Goddess]

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?
