cylinder 4 and 6 are okay but the exhuast valve for 6 and 2 is bent and intake valve for 4 is bent

hey guys , i found the problem. i took off the heads and piston number 2 has a crack or melted hole in it. it has a small hole where the top of the exhuast valves would be. i assume it was hitting the exhaust valves. and now i am wondering if i should rebuild the engine or just get a new...

just an update , i checked to see if the head bolts were loose at 50lbs and some of them were, so i retorqued all of them to 80lb. i put all the parts back together turned it on and had a problem with cylinder number 2. i did the spark plug pull thingy where you pull the spark plugs to see which...

alright well heres the results on the compression test #1) 120psi #2) 0psi #3)140psi #4)0psi #5)120 psi #6)0psi. i put oil in the #2 to see if it was the piston rings are worn but it was still at zero. im guessing need new piston rings or seals or rebuild :cry:

alright well i started the car again and theres no more blue smoke. but it does still misfire. i took out the spark plug. spark plug #1 had a black dry color on it , number #4 and #5 and #6 were wet and black, #3 was dry and blackish and #2 was clean but oily. i kinda did a compression test but...

hey guys my 1988 7mgte supra is smokeing lots of blue smoke and is misfiring badly. i was on the highway for a while and the car shut off on me. i was only going like 110 and i pull over popped the hood and there was smoke around the exhaust manifold, i heard a pop of air when i started it back...

Thank you very much i will try adjusting the tps again and check for boost leak

Hey so i connected the te1 and e1 together just to check for codes, and it just blinking rapidly no pauses or anything it just keeps blinking by seconds. My 7mgte stock with boost controller 6.5-8 psi cuts out on me when i hit 3500-4000rpm with like 5+psi at half throttle.so as it was blinking...

Thanks,I found it. it was really obvious but the dirt and oil made it hard to find...I unscrewed it and there was no medal.Drained it and put in a new synthetic gear oil 75-90. I drove the car around for a while and Its still making the whining noise in 1st gear and gets louder the...

get it machined i ment

Alright thanks nick!

I didnt I was planning on sanding and cleaning it myself.But sense you asked that I might think about doing a 2.0mm instead just to be safe.

yeah thought so too, gonna get a 1.4mm metal headgasket with head studs soon, thanks for the feedback. Let me know if you have any tips or anything.

today after refilling the coolant and driving it around, the supra would stall or do a 2step around 4000-4500 rpm at 50% throttle then at 100% the car would go pass the 4000 and would be fine at 100% throttle when i got home and popped the hood theres high pressure steam blowing out from the...
