Cometic Valve Cover Gaskets Nissan RB20 RB25 RB26
The first gasket you'll want to replace on your aging RB20, RB25, RB26 engine is going to be your valve cover gaskets. These gaskets are fitted per side of the engine on each of the cam covers. You'll be surprised how often you'll find that your oil leaks are coming from old dried out rubber valve cover gaskets that haven't been replaced yet.
Perhaps one of the easiest gaskets to replace as they're directly on top of the motor and require just removing the valve covers. These are priced for a pair of OE replacement gaskets so you'll be able to get the complete job done all at once.
Don't forget your half moons!
