They should have done it.

So a leaking RMS after 2 years could be a sign of INCREASED Crank Case Pressure. Check your CCV system!

I don't agree with people saying it leaks because of no use!
How about car stored for winter, does it leak in the Spring?
How about car parked at dealers lot waiting to sell?
How about Seals sitting a few years on the shelf waiting to be sold?
No he told me that the Trans seal looked good. BTW where are the 4 seals located?

I had him check the CCV while he had the car and he said it was good.

I have to say that I do agree with what you are saying about the car sitting.

I will say that the day it started leaking, I took it out for some spirited driving and that's when it starting leaking. Do you guys think that's what caused it?
