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!

Apparently we're the only ones besides the owner that realize his engine troubles go a little deeper than fuel and spark.

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.

Talking Re: Spark Plugs What is wrong?

I stand corrected! Knew it was one of the two!
