Hello all, I am doing a rebuild on my engine. I have lots of blow-by and oil consumption as well as oil out of the exhaust. Pretty much worn out. I am trying to do this on a budget, but not cheap out on parts. I would love to replace all with Genuine parts, but I don't think I can swing that. I am avoiding Britpart items, I am buying the full lot from Rimmbros, most of the parts are the "OEM" labeled. My question is which part would you consider the most critical to use Genuine parts. Things like motor mounts I know are not an issue, but rings, bearings and such may. Thanks for your 2Cents.
