Oh no... I hate to be asking a question already about my freshly rebuilt engine but I'm quite concerned and want to get other people's opinions on if my concerns are valid and if I should be even more worried! When I got my engine back from the builder I noticed the oil light coming when I was stopped at stop lights or cornering. I spoke to the builder who thought there may have been a problem with the oil that he put in the engine - as the same thing happened to another kombi engine he had just rebuilt. Apparently thicker oil sorted that out and he suggested I take the same approach. I drained that oil and put in a new filter and put in some fresh run in oil. Problem seemed to get worse and red light on more often when idling. I drained that oil out and filled up with Penrite equivalent to 30 weight oil and yesterday after a run on the freeway the oil light was on at the lights when I got off the freeway. Of course I will be going back to my engine builder with this info... but I have read around the traps that this can happen with newly rebuilt engines... has anybody else had this experience? Should I be worried? I know my engine builder will be suggesting trying even thicker oil... but should a freshly rebuilt engine be requiring thicker oil than standard Type 4 engines would take??
