In few more days I'm going to get a coolant tester so I hope it's not a blown head gasket even though some guys from driftmotion came to check my supra (Thanks a lot guys) and told me about some problems such as exhaust leak from the manifold, old engine harness, tps, afm, valve seals and the damn bhg. There's no oil in the coolant yet. The only reason that i bought this supra was because of the warranty. The engine had been rebuilt 15,000 miles ago and now I have this problems I did not overboost it. Now I'm having some problems with ATK company about my warranty. The owner paid $3550 for the rebuilt without the turbo. I could've swapped a jdm engine or maybe a 1jz. Now they want me to take it to a shop pay first and then they're going to investigate if it was their fault. If they're not going to pay for it I'm going to put a 1jz instead.
