This is on an engine that never had a questionable compression test.


More likely a worn out turbo seeping oil past the seals in that case (full turbo failure will quickly fill your IC with oil)


Shouldn't be an issue with a Rotrex though.

The 94 from husky is much better than 91 vpower. 94 octane is 94 octane...it just uses some ethanol to get there. I have no problems running full timing on 94 but if you switch to 91 it will pull timing. They can't use more than 10 percent ethanol in regular fuels.

Or just maybe it came down the black oil trail on the inside of the turbo inlet pipe that started right at the crankcase vent connection...

But hey don't take my word for it. Your single case where the crankcase vent didn't cause the intercooler to fill with oil clearly trumps the real world experiences of everyone else who has had an issue.

I don't have this supercharger but I just read through the installation manual online to pre-prepare and it sounds like it's really confusing or is it only because I don't have all the stuff in front of me??

You just need the car and the parts in front of you. Take your time and you'll be just fine.

If you're still unsure, have a local shop perform the install for you; if anything happens, they'll be liable.

It may look confusing, but once you start it really isn't.

I have NEVER installed an SC or turbo in any car before and I was able to install everything without any issues... including the Ecutek flash which was a first for me too.

I started early Saturday morning, took my time, did an oil change, installed the JR Oil Cooler Kit, pulley kit, DSS driveshaft, and took pics throughout the process... Ultimately finishing late Sunday morning...

The owners on here are also willing/able to help with any questions you have throughout the install. We are all pretty active forum members and one of us will likely help/answer any questions you have.

Close to the refineries (folks like you and I) yes it's "close" but still not 94. Anyhow the further away from creation point it's less productive fuel. Transport of gasoline has a negative effect from agitation, ultimately numbs fuel to simplify understanding.

Im new to the FI thing, was curious to know would i need extra cooling even if i drive in little to no traffic, and only about 20-30 miles a day? I apologize for my lack of knowledge and undoubtedly stupid question. Any advice or answers would be greatly appreciated.

Or you're ignoring that you really did have issues as that's a clear indicator of an engine on it's way out.

The oil cooler is nice to have, but not necessary at all for just street driving.

A Moroso vacuum pump is comparable to a PCV system now? Wow.

Would you like to discuss the horsepower gained from the evacuated crankcase (on a motor with a third of the piston underside surface area of that rat motor) and how that compares with the horsepower lost from the intake system being restrictive enough to allow a turbocharger to draw the kind of vacuum it would require to actually evacuate the crankcase? Because we could do that...
