Hi
I have just installed Nippon rings with CTR pistons in my B16A, i am burning some oil though which i think is because of pcv, their is blue smoke when accelerating hard. my compression is 210psi all the way across, this is with crane cams, but when installing the rings i cant rember if i checked to see if the rings go a certain way up, maybe because of a taper, I hope these rings have no taper, im such an idiot and this is giving me a big headache any help much appreciated.

Thanks

 

Did you atleast make sure you staggered the rings?

 

hows the valve seals and guides?

 

Yes, they go a certain way. The second ring has a scraping edge that needs to be facing down.

 

Ok thanks for the help i did stagger the rings, im thinking about stripping the engine down, because im not sure if i put them the correct way up, i have replaced the valve stem seals but not the guides or valves. The car runs realy good apart from burning oil under hard driving, which i can live with as long as it doesnt get any worse.

 

My last easy guess is to make sure your pcv system isn't clogged, or has a vacuum leak.
