on my turbo ls/vtec i was looking for the sening unit on the back of the block and it isn't there. whoever built the motor put the t in there and went off that for the oil feed to the turbo, and the vtec, but where would the sending unit be now? the oil sending unit just tells the oil pump how hard to work, right. can the car be running without one, or is it somewhere i don't know of?
