I did a cam, push rods swap and now i got smoke from my number eight cylinder from burning oil. It was the only plug i pulled out that was soked in oil. But I only did a cam swap with the heads on the car so the clyinder was never exsposed. Well the car starts and runs a lil rough like its missing had the ls1 edit put on it so i know the mis is not from that. it wasnt that big of a cam so i kept the stock spring in it so could that be a problem. I've run about 800 mi on it so any idea its the normal finger print smoke can be disragared. But like i said the only clinder geting oil is the number 8 so help or insight could be helpful.

 

what are the cam specs??

 

Z+220 SDPC LS1 Custom Camshaft - 220/224, 0.551/0.551, 114

 

Might have a bad valve seal for that cylinder,

 

but it was like it went bad over night what would have caused that

 

stock springs are a no no with a cam like that,you might have broke one.dont run it at all until you check it out real good.

 

Busted spring and then a damaged valve stem seal, good chance that is where your oil is coming from.

 

you better pull valve cover before next start. dont want more damage if you allready did.

Cam like that you needed to upgrade the valve springs,you have a seal that also needs replacing.

 

are ls6 springs tough enough

 

just go with a 918 spring. And it sounds like you need a new seal.

 

ls6 "yellow" springs would work. rated at .570 max lift.

 

You need to change the srpings but I would check your spark plug wire. Is it oil or black soot? If black soot, it is not firing correctly and likely just the wire not connected properly. I recently did the same thing so start with the simple things.

 

look into PAC beehive springs. they are a little cheaper then comps and just as good. and surely you aren't gonna say that no one told you that you needed to replace valve springs???
