Thanks! I hate going to the doctor. Looks like I'll be saving a ton of money on my next colonoscopy.
Ok, you guys are weirding me out. Should I really be getting so many "likes", when I talk about giving myself a colonoscopy???




Ha ha ha.....

No no no. We want the link to the one YOU bought! Wtf.

OP my first thought was regarding mechanical interference from the cylinder head.
Have you "dropped a valve"?
Not that I know of. This my daily driver and it makes no weird noises.

Same everyone else said.... Leakdown check, borescope...

When checking the rockers/pushrods, try wiggling the top of the #6 springs- looking for a hammered valve guide. It sure looks like oil consumtion in that cylinder, to me. A ton of carbon there compared to the others.... That could lead to a hot spot, then detonation, blowing off that electrode. (Remote possiblity....)

Does it smoke out the exhaust at all? Pull the pcv- smoke out of the valve cover? Out the dipstick tube? Does the motor have any new/different sounds or noises?
No smoke out of the exhaust that I’ve noticed. I’ll leave it sit outside tonight so it will be cold in the morning and ill see if it smokes any when cold (normally I leave it in the 50 degree garage). I’ll check those spots for smoke and I haven’t heard anything new or different

If you had , you would definitely know! LoL :)
You still drive it? Simply changed the plug and it's like nothing ever happened?
That's a square body Chevrolet for ya! (Don't ask an LS motor to do that!)

After I looked at that picture long enough, I guess I was imagining valve prints on it.
Anybody else see em?
