Clutch safety switch stopped responding. Switch was by-passed until find a new one.

Adding an oil air separator ahead of the PCV prevents this from happening and saves the engine if discovered early, before oil is gone! dashboard coming apart, fast deterioration, even if the last year is under cover. Covered with Vinyl carbon fiber sticky roll. looks great.

Was working for a dealer and had good discounts on repairs and parts. Bought this car knowing it needed some work: Repair oil leaks and any collateral damage resulting from constantly burning and leaking oil. Replace valve cover gaskets due to leak, both banks. Defective valve cover creating excessive oil consumption, mechanic did a no-promises repair for free while it was off and resealed with silicone, has not shown signs of leaking since. Oil cooler o-ring leak. Replace spark plugs, assumed damaged from burning oil they were also easily accessible while other work was being performed. Other maintenance items done at this time also.
