Hi,

Thanks for all the responses. I do have one question on the "normal" oil accumulation at the air horn/air bridge area. One aspect of the comment from Mark H that I should understand is the time element. How long should it take to accumulate 2 cc's of oil. My accumulation occurred over a couple of days of driving and about 100 miles of driving. Seems high to me.

I fully understand oil back-streaming in a partial vacuum but this oil is on the atmosphere side of the TB. The air stream is going "from" the air horn area so where did the oil come from ?

Cheers,

Don
