| It can't be head gasket. VG30 blocks have good gaskets and only way for the gasket to get blown is severe overheating where the heads will worpe so bad causing the gasket not to seal enymore. Also even if your engine had slight head gasket leak it would overheat in minutes forsing the coolant passed radiator 13lb/ft cap. At this point the engine would sease up. Clogged PCV valves can not cause the car to smoke that bad. Am sure Z1 recognised the odor of the smoke and determined it was oil burning. Stock Z32 PCV system had two hoses going from top of the intake valve covers to the turbo inlet so the positive crankase pressure will vent there in case the PCV valves get clogged and that will prevent exessive crankase pressures. Z1 lied to you about PCVs, if they did the engine they probably at least checked the pcv valves. Here is what I think it is: your car:1990 Maroon 300ZX Twin Turbo (approx. 516rwhp @ 22-23psi w/ race gas)
- Bunch (built by Z1 Motorsports) 22 psi on now running 91 octane!!!. There is no way that 3.0L engine make 516RWHP on 91 octane........... and 22 psi of boost on 8.5:1 compression ratio and 91 gas WOOOOO[ WWW. ] Result is SEVERE DETONATION causing the piston rings or a piston to crack. I know what they did, they knew about it and told you that is something simple. When you went on lunch brake they turned the power down hoping reducing power will reduce oil consumption/blowby Simple compression test will determine if am wrong or not. Am guessing they will give you crap or drag this until the warranty runs out. Maybe they told you can't boost that much on 91 but you ignored it. We need to hear their part of the story.
