How many RB engines bite the dust with very low milage? Who here had never a stupid problem like CAS, Coilpacks, AFMs or other million things like that that keeps him from driving it? I had all the problems above and more, as a lot of other people. Every year a new one. Some more than once. Also a cracked head from one day to another. Almost knocked out oil pump drive. Always took (way to much) care of the car. Also a lot of other people I know had similar problems. And a shitload of people online had this problems in my more than 6 years as a owner and always online searching forums everyday. If yours is fine, enjoy it before it goes bang. And start saving money for a rebuild. Of course a lot of the needed engine rebuilds you see are done because of careless modifying/servicing from (previous) owners. As always said, don't buy a Skyline if you can't afford a engine rebuild. The stock engine WILL blow! My personal opinion: I hate RB engines, but man, I love them when they are running. Could never give it away.
