Re: Spark Plugs What is wrong?
Just curious, you're running an Edelbrock carb. Are you still running a stock fuel pump, or a low pressure pump? Stock pumps put out too much fuel pressure.

Re: Spark Plugs What is wrong?
He has bubbles everybody.
I had a head issue I got through this time last year. I had a plug that was stuck, wrung it off flush, removed head(s), magnaflux found crack, better performance rebuilt heads, I'm a happy camper. Hopefully it's just a gasket for you. I guess my plug was rusted in from coolant. Truck never smoked and ran great till I broke the plug while removing to take the header off to access the brake line/hose union better. Talk about a snowball! Good luck!

Re: Spark Plugs What is wrong?
Yep...he has a constant bubble stream in the radiator...obvious water ingress into at least three cylinders...and an engine running like KRAP...
Pull the heads and take a look... Post a pic of the heads once they are off... Then we can all see what the issue really is...  Its a Chevy...its not rocket science...

Re: Spark Plugs What is wrong?
^^^ This. I've used a buddy's SnapOn emission sniffer for this. I put it on CO (not HC, though maybe either works) and sniffed the filler neck, and even in a car where the leak was slight enough that there were no visible bubbles, the CO count would shoot up when placed over the filler neck.

Re: Spark Plugs What is wrong?
I stand corrected! Knew it was one of the two!
