A while back, I posted and asked about running the blow by from a 4 stroke engine back into the tank 1. to prevent a lot of cleanup, and 2 to possibly increase tank pressure...like a pump. Well, I did it on my TT 91 fs, and it works...it works really good! The engine actually seems to run better, and I had virtually no clean up to do when I was done.

Now, back to reality...This has to be too good to be true..right? I have never seen this done before, and if it was a good idea, it seems that I would have...but I have only been in the hobby for a year.

Anybody have any thoughts on possible detrimental effects. A guy at my LHS said that it was not meant to be a closed system and it should be left open, but he gave no real explanation of what might happen if I did run it this way.

Thanks,
Kevin
