Spark Plugs What is wrong? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

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.

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...
