[jimski]

All of a sudden now alot of smoke blows out of the valve cover openings. PCV is working and good. When im driving u can see it blow out the sides of the hood. any ideals whats wrong

Subscribed... Could be the rings on thier way out, Valve seals? I have the same problem

 

[TurboBuRick]

Could be a blown hg. Could be cracked rings. Could be a hole in the piston.

A leak down test should tell the story.

 

[jimski]

car runs and drives the same thou, just the smoke blowing out

 

[TurboBuRick]

Prolly a cracked ring then.

U might be right, theres no water in the oil. The engine smoke is kinda like steam thou. It dissapates kinda but still smokes the place up. All the plugs look good.

Do a compression check.

I will, my boost/ vacuum gauge is 22hg like it was before. weird

Vacuum isn't a sign of anthing other than a decent condition engine Jim. Get the copression test done and do it dry and wet to see if there's a difference. If one cylinder is weak it will show up so you have a better idea of what's going on.

and make sure your pcv valve isn't in backwards lol!

 

[usetaboost]

and here's another question...Is it a correct gm valve for a turbo car?

The actual valves or the covers?

I think he's talking pcv.

Yes it is the correct unit. I think i smoked a piston or something of that nature. It kinda cold started today, heard a little low end knock, but went away once warm. She was pinging a little too before all this under boost ( i would quickly back off thou), when the car warmed up it would not ping anymore under boost. I think i knocked the little s hitter to death. "(forgive me for saying this)" Im going to yank this crap out and do either a 502 big block or a turbo sfi swap. Ill see.
When i tear it down ill report back.

will a 2004r fit a chevy 502?

It was a slug anyway and i was kinda happy with it.

If the trans has the dual bell housing then it's a direct bolt up. If not then you can get an adaptor Jim.

 

[jimski]

Well opon further inspection today not only is there a smoked ring on piston #6 but there is a hairline crack on the skirt of number 6 piston and number 2 piston (basically both cracked on the skirt) ..
I need a new set of standard pistons for the block. Any ideals on a top of the line set.

 

[charlief1]

Got a used set here Jim. Engine had less than 80K on it if you're interested. Rods included.

I'd get a knock gauge from Casper's Electronic so you can see what's going on.
