Ok Here it goes,
Car:
1990 300ZX VG30DE 5 Speed, 2+2 Model .. 124,xxx Miles..
Sat for 5 Years when it first started smoking.
I thought I may need a Headgasket.. but I am unsure now.. I am blowing White Smoke out of the Driverside Exhaust, and a hint from the Passengerside Exhaust..
Now what I thought, White = Coolant, BUT I am not Over heating at all.. and I am not using Coolant.. No Mixture in the Oil... No loss of Oil...
I started a Compression Check, removed all Spark Plugs, Fuel Pump Fuse, after car was warmed up.. But due to Bad luck that damn Comp tester Seal broke on the last Cylinder
When I removed the Spark Plug (Driverside - Front of the Car back order ) the First 2 were black..( These are brand new plugs with maybe a Mile on them ) .. the Last Cylinder was wet (fuel) but not black...
Passender Side - all Black..
So I figured a Easy temporary fix to my problems, if it was the Headgasket, would be Steel seal ( Until I decided either to replace the DE, Do a TT swap, or do a VQ35DE swap.. )... I have had 3 Different friends try it and all there's were blown headgaskets and the stupid crap works... BUT, I put it in lastnight and it improved the smoke just alittle bit.. But once I hit the gas more smoke comes out
I do have a Ticking sound coming from the Motor...
Also, not throwing any Codes...
Here are the Symtoms:
White Smoke (but not Over heating and not Coolant Usage )
Loss of Power Threw all Bands ( Massive Dog, Bogging )
Inside gauges not functioning right ( Tach will drop to 500 RPM's here and there then start working again just fine... )
Revv's up Fine, But if I revv it repeated right after and tap it up and hit it again if will hesitate and sometimes backfire..
Here are some Other Notes:
Idles just perfect
Revs up fine to a point ( listed Above )
Things I have done:
New MAF ( Fixed Idle Issue/ Revv Issue from before current Issues)
Brand New Plugs
Oil Change w/ filter
Air Filter
Fuel Filter
Steel Seal (No Luck )
Compression Check on Driverside bank (except last Cylinder closest to the Firewall, Stupid Seal on my Comp tester ripped off and i did not have a replacement) But I was in the Mid to High 160's... I also did it to the Manual Specs (warmed up car, Then disconnected Fuel Pump, Opened Throttle on Crank.. Cranked 4 Cycles.. )
I hope I put enough information .. Please let me know if I left something out or need more information...
