mk3 supra smoking out of exhaust

2fast4u · 04-13-2012, 04:50 AM

hello i got a 7mgte with a new turbo and new seals and gaskets. i bought a gasket set from toyota dealer with the head gasket. i had the head inspected for leaks and cracks and also i used arp head studs torqued them to 86 foot pounds and also cleaned the block properly. there's smoke coming out of exhaust manifold side of the car from where the turbo connects to the exhaust. i think it might be the new seals forming in place. what do you think please help asap iam taking car for emissions tommorow. also the smoke is little white not to much smoke though coming out.

Smoke = New seals forming in place????? Is that a joke?

It's possible you've got cleaning solvents and lubricants which poured down the engine and head in the repair process burning off... Really there shouldn't be more than a mild 20 or 30 minute drive on the highway wouldn't burn off.

Otherwise.. You've got an exhaust leak.

86 ft lbs on studs? What brand, what lube, and sis you read the directions? That number's lower than it should be for ARP studs and too high for ARP or Toyota head bolts.
