i did a compresion test on a 7mgte that was extreamly poorly rebuild by a horable mecanic.cylinder 1-4 were at 180 and cylinder 5 was all the way at 300 and number 6 was at 240 ish.those numbers sound bad..do you guys think its got something to do with a piston or valve? i guessing its worse than a bhg,but the car did overheat one time. any advice would help.thanx

Fully charged battery with a spare+ Jumper leads
All plugs out
Throttle @ 100%
Crank for 3>4 compression strokes on each cylinder
Write down the result 0 guage on the tester and repeat for each cylinder.
300 isn't reality no idea how that came up.

ok that makes me feel better.what do you mean by Throttle @ 100%?? floor the gas when i crank the car? sorry to ask such dumb questions,but im nowhere near mecanicly inclined
i did pull the fuse,but i will re test tommrow.what does the tester usualy say with a bhg? ballpark figure. did the 180 sound bout right?
Do you have any other BHG symptoms?
Coolant in the Oil?
Milky crap under the Oil Cap?
Were any of the plugs wet with coolant?

no milk under oil cap.the turbo has been smoking also.im asuming the seals in it are going bad.but other then that i dont see any.idles fine.i did notice some oil in my throtle body though
ya.got exhaust manifold off.doing intake manfold on monday if we got time.also there was oil puddles in the valleys wher spark pugs were.i swear the mecanic put my motor together with a cressent wrench.the coolent in the cylinder would be from a bhg correct?i dont have oil floaties n my radiator though.
i bet thats what happened they did a horable job on my car and i bet he didnt torque anything.just got my cash and ran.i know its totaly off subject but ive searched and cant find whats the diffrence between a stoper or bead type head gasket?whitch would be best for a daily driver.i see where to figure out the thickness but not that part.thanx agian
cool.should i go greddy or hks?u seem to know what ur talking about.i apreciate the help.most ppl just talk mess cuz im lost.
I'd go Cometic/TMS whichever you can get the best deal on.
