I’ve never heard of a crank case vacuum pump until now but after doing some research I really wish I got the chance to try this on my old motor. For anyone suffering with the same blowby issue, it may be worthwhile to try this. Thank you, Rabrooks!

Thanks for the updates. I am contemplating boosting my FRS but when I read stuff like this it really makes me not sure if I should go through with it. Especially when it sounds like all 3 of you are having similar issues even though you are all using quality parts.


What are you planning to do now?

Built motor. As for my oiling solution, I’m kind of keeping it secret until I do a reveal on my YouTube channel. As far as whether I recommend boosting, I would say if you’re willing to spend time and money problem solving and willing to pay for a new motor incase things go wrong, go for it. But if you like simplicity and reliability then don’t. It’s hard because some people boost with zero issues and some people blow in less than a year like me.

x2 Rabrooks, we found on track cars with turbo the crank case often had positive pressure and blew oil. Putting a vacuum seemed to do two things; we controlled the oil out of the crankcase , but more importantly it seemed to reduce the oil coming from the crankcase. I do not know why but lower internal pressure seem to help quite a lot with keeping the oil out of vapor.


If you were two quarts low and on the track you might have oil starve the engine in a turn. Baffles, accusump, drysump. Sound expensive but compared to an engine rebuild? Well forget the drysump it is the cost of a new engine by the time you get through. I personally like the accusump as an answer to tracked but not raced cars.

I don't post often but here's a link. Hoping to have the motor and car back shortly and I will start making content at that time.

Dang, now I really wish I tried the vacuum.

Yeah I definitely starved the engine of oil which led to the engine failure. An Accusump is a great option but unfortunately not a lot of people make kits for the FRS/BRZ/86 platform. I was looking into the one element tuning makes.

I'm hoping that my next oiling solution will solve the blow by issue once and for all since I really do not want to invest in another built motor. Time will tell.

The accusump is very easy to install in about any car. That is why very few "kits".
