i forgot to mention something else. at the back of the head goes down the the turbo manifold seem to be a sign of fresh oil that is leaking from the head. my buddy just replace oem head gasket to a hks metal gasket...

 

ouch that seems like soemone didnt get the head cleaned good enough or didnt clean the bl0ck good enough or didnt take the rivet out of the head gasket before he put it in...if there were swurls on the head it could cause it to leak check your compression you may be getting shitty compression do to the head gasket not sealing and white smoke? not good could be the coolent leaking into the exhaust or may just be oil from the plugs but that normaly goes away fairly quickly keep an eye on your coolant level you may have bent a valve and its causing the bogging...im just shooting here im not completly sure without seeing the car if someone thinks im wrong in any way feel free to jump in

 

the last time he check his spark plug, he told me that it has coolant on it. actually it was a mixture with oil and coolant. and once he cleaned it up and put new spark plug it ran good for about 3 months....and it will acted up again. so now it didn't have no coolant...just whole bunch of oil fill up 5 and 6 plug. can he still able to drive the car temporary awhile the car is smoking white?...and what is his chance or remove it....? he is really sick worried.

 

i wouldnt drive the car...imo

 

that case what should he do at this point? the car is smoking white and head gasket is leaking and oil is fill into the spark plug cylinder (whatever you call it) any suggestion? to get the car run normal again.

 

take the head off and start from scratch or sell me the car and buy a new one

 

dun dun duuuuuuuuuuun

 

LMAO omg i almost pissed myself when i saw that...il take some picks of my head gasket the last cylinder of the headgasket was hanging out of the back of the motor...no good

 

well at this moment my buddy is looking for an head gasket. either a performance or oem. not sure. plus also he looking for a shop that do it for reasonable price to replace head gasket.

i would of done it for him if i know much about supras...

so now it start up without any white smoke...but alwhile the car is moving...little smoke coming out and then a huge white cloud. so now the car hasn't been running ever since this happen.

 

metal head gasket get the hks stopper head gasket or a comitec 2mm the stopper is 400 shipped but its well worth i tthats what i have in my car and take it to f&h performance they will do it for a reasonable price i payed 800 for them to pretty much rebuild my entire top end
