Brian,

Thanks for your comments regarding the 86 505 turbo cars. It looks like the
N9T engine might have some problems I wasn't aware of.

Following your post I went to my car and looked for the symptoms you
described. I could only notice some air puffing out through the crankase
when the oil filler cap was removed. Your post talks about "a lot of
puffing"; how much is "a lot" this case, where is the boundary between
normal and not-so-normal?

Thanks,

Radu
