I got a bad feeling about this one. My breather used to go into the end of the K N filter, (CPR TURBO) I added a seperate filtered breather and there is a constant steam/exhaust coming out of it. Not much, but it is constant. It doesnt change on throttle settings/boost. The oil still looks new after 100 plus miles.
Could it be the head gasket? I just had to replace a Head Gasket on my ASV 60, diesel cat/perkins, that was sending a cloud of exhaust out the breather...this reminds me of that a little. Is that possible that it could be exhaust. Sled used no oil in 100 miles and no anti freeze. Man I hope not.
