my NA is burning oil a little....actually when I shift gears when I'm racing, a big puff of smoke comes out after every gear change. Should I use those NO-LEAK and NO-SMOKE products out there? Do they actually work? Right now I'm using the CD2 engine restorer...

 

umm, I wouldn't use any of that crap out there... Most likely designed for a piston engine, and might eat yer apex seals, or whatnot...

You have bad oil control rings..... The only way to fix it is take the engine apart and replace them... (yer general overhaul)...

Pouring that junk in could mess stuff up even more.. be careful..
