I have noisy tappets which is only present when the car is ticking over. So I was thinking of flushing the engine out and then putting in some decent oil. I have Castrol GTX Magnatex in at the moment.
I heard you can flush your engine with desiel, is this true. If not whats a good flush to use and how long should I leave it in there before putting a good oil in.
Also what its a good oil to use on my Cav SRI 8v its done about 125K and smokes a tiny bit.
