I'm sure you've heard all the pathetic excuses...marriage, kids, career!! Well, my 87 GN has been parked and sitting in the garage for about 5 years after hearing a loud pop and then top end rattle. Turns out it had a broken rocker arm shaft. The pair was replaced w/push rods and plastic inserts. The car is stock for the most part and has 67k miles on it. Injectors and chip are stock, Flowmaster exhaust by original owner...when the cam went it was replaced w/a Lunati 200/200 which has about 3-4k miles on it.
It started at the touch of the key the 2-3 times I turned it over when she was broke. Recently, I syphoned fuel out of it, drained the oil, coolant and added new fluids. It starts right up w/no knock at all but does have some light gray exhaust smoke. It's not extreme but it also has that burned exhaust smell that stays w/ ya!! It surges at times while idling but doesn’t stall. Popped two of the plugs and they were nasty black.
I planned on new wires, plugs(NGK), pcv, O2 sensor, MAF, fuel filter, cleaning the intercooler, and installing the Scanmaster 2.1 that my awesome wife bought me for Christmas. I also want to check the stock turbo…I guess check for oil in the downpipe and play in the shaft? And pop the valve covers back off to peak at the valvetrain in motion. Probably should add a passenger side valve cover breather while I’m at it, huh?
Planned on a TT chip, new injectors, upgrade fuel pump once I get the smoking issue resolved. What are the chances that the smoke will subside after running for awhile, and is there anything else I can do to try to correct it? Too rich? Turbo problem? Cam issue? Is there any other precautions or things to look for since it’s been sitting? Are the Scanmaster readings going to be that helpful? I don’t want major failure from running it w/the smoke. Feel guilty enough it’s been sitting neglected…don’t want to make things worse! Guess I’ll shut up and get to work!!
