Hello all,

I just picked up my 1973 240z :) runs pretty good. I have a issue it seams with oil in air cleaners ( dual weber downdrafts, don't know the numbers of them ). Is this blow by? If so how do I fix it.

Thanks For any help.

More than likely it is blowby. First thing to do would be a compression and leakdown test to find out where the problem is. It could be in the valvetrain or rings or a little of both. Until then you could run the breather hose to a catch can until you get the problem diagnosed and/or fixed.
