My 617.950 uses very little oil; only about (1) quart every 3,000 miles or so. However, like most 617's, it does produce an oil vapor out the crankcase breather when running . I am addressing this in Dad's 617.952 by having Total Seal modify the new MBZ second rings, making them gapless.

On my 617.950, the wastegate has a sqaure hole in it that sometimes releases a dop or two of oil onto the RH motor mount. Has anyone tried using an oil separator in this circuit????

Your thoughts and accounts are appreciated...Robert
