i have a 91 db1 and just looking for suggestions on what parts I could put on to expand the engine life, im doing a valve adjustment this weekend and putting in a new cam plug where its leaking and the motor has 200xxx, I have fixed all the other leaks and its running pretty good for now. Just wondering if there are any parts I could install to make the engine run longer besides changing the fluids. someone told me to put a oil cooler on but i thought thoes were mainly for turbo engines. any suggestions would help, i have about 400 to get some parts, and im not looking to do ls/v, just looking to expand engine life as i build a engine on the side
