Sam, the car is only out a few times a year , as I have another 90 and then also have a turbo coupe to drive in the Summer ...... So as the engine runs I see no oil on the ABS master cyl . I see No smoke from the exhaust . As for oil use, I do not drive it enough to see any lost oil , if any is coming off and into my catch can , off my PCV valve . pass. side valve cover as it runs and is warmed up , has then to me , way to much coming out from it , it like a small exhaust port . And with the oil cap on , it has some oil leaking from it . Had this car for years and engine kit from past owner got it all from Bill Hull , was called the 340 HP kit . I do not own a compression tester . But seems I am getting this pressure from both sides of the valve covers , PCV area and oil fill spout . Still runs good , but I want to make sure that I do not hurt it more , if in fact it is hurt . Big thanks for the reply ..........DW
