Nice day here in Pittsburgh. The birds are singing, the sun is out, so I decided to back my Alfetta GTV out of the garage. I have been driving these cars since 1980 and something peculiar happened. She idled OK but a ton of smoke came out and the oil pressure gauge barely moved. Usually the gauge works fine until the engine warms up and the dies, but now it acts like it needs Viagra. Any ideas. I am thinking that tomorrow I'll take her out for an italian tune up. ( Get on the freeway and rev the crap out of her to get all the nasties out. )

Blowing the cobwebs off my Alfetta

Bad oil filter? Good point. maybe an oil change is in order. I think the smoke was black. Its a spica injected car with a Shankle Sure Start hand pulled actuator in full cold start position. And its a burgundy color.

Great looking car. What is the color name/paint code for that? I assume it's original color. Does it still have the color sticker on the underside of the rear hatch?

Not sure of the color since original color is black. The PO says he had it painted a GM color from 2003.

Ahh..gotcha. Mine is also black and getting ready for a color change. Did the PO leave the engine bay black?

Actually, I like the black engine bay.....I wouldn't remedy it. I was just curious if they left it black. Black engine bays are quite common regardless.

Stuck oil pressure relief valve, maybe?.

Oil pressure relief valve

The relief valve is part of the oil pump. To get to it you drop the oil pan and remove the oil pump.
Before I did that I would remove the oil pressure sending unit at the rear of the block on the intake side and hook up a mechanical oil pressure gauge to check the pressure. Dropping the pan is a bit of work to have it turn out to be a bad sender.
Black smoke is unburned fuel so I would think you have two separate issues.
I would get the oil pressure figured out first and then go after the running rich.

Back to the original idea of this comment....Did you say the smoke is black?? That sounds like un-burned gasoline, not oil. I'm not up on the Sure-Start, but is it possible that, acting like a choke on carburetted cars, it is putting too much gas into the motor, causing it to run rich?

If that is the case, I'd suggest backing off on the amount of "choke" you are giving it. I had a Spica injection unit go bad on my car, a '76 Alfetta GT (Ivory in color, and original color, but a re-paint, btw) and it smoked a lot, black smoke, as a matter or fact. Had the Spica unit replaced, and all was right with the world.

best of luck with yours

And to think that I thought this thread was about a man that hasn't "done it" in a long time. Where is my mind :)
