#INSTALL OIL CATCH CAN ON POLARIS XP TURBO PLUS#

Removed the engine and rebuilt it bottom to top. Performed compression test and cylinder leakage test and found leak down on all 4 cylinders to be more than 20 percent.

Short drives around town nothing but longer drives 20 plus minutes straight driving then come to a stop and clouds up around the vehicle. On the fifth day they drove a longer distance and found the smoke had returned after long drives. They drive for few days and said smoke had stopped. Customer then picked it up before I was ready to release it as I wanted to drive it till smoke stopped. I installed the new (used) turbo and all was well with performance and did smoke a lot for first two days burning the massive oil deposits out of the exhaust system. The vehicle was brought to me originally for large amount of oil in the exhaust and the factory turbo was bad ( excessive play on turbine shaft) and customer opted for a used one off line to save some money against my recommendations of a new one. Hi Tim, I have a 07 Acura RDX that’s all stock components. The turbo specialist says there is no issue with the turbo, the mechanic seems to have hit the limitation of his knowledge and is blaming the turbo… reading elsewehere maybe checking the return line further beyond the pipe ? crank case ? sump ? i dunno. i have no turbo symptoms either, no smoke in the exhaust, no loss of power, no noise. its sort of bleeding out of the same area of the turbo, accumulating and dripping once maybe every 20 mins or so when running. all reassembled the turbo is still leaking, although nowhere NEAR as badly. The turbo was taken off and checked at a turbo specialist who found no faults whatsoever, the oil feed line and oil return pipe were changed along with the gaskets as a diagnostic / process of elimination measure. literally pouring out of that area.unsure if it was a crackwed pipe or blown turbo. It was leaking oil from the middle of the turbo between the two turbines, where the oill feed and oil return lones are. This post is getting a little long so I will make a part 2. And the seals are more designed to keep turbine and boost pressure out of the crank case. The piston blow by back tracks up the return line. The return line is connected to the crank case. Why can these two reasons make the turbo leak? Well, it’s as simple as blocking off the oil return line on the turbocharger. A bad PCV system can make the turbo leak. Next you should check crank case pressure. This is the most popular failure I see in the small frame turbochargers. That makes the groove too big for the seals to keep the in the oil. That is when burn oil has cut up the steel on the turbine shaft. If you do, you are in the beginning stage of thrust bearing failure. But, it shouldn’t touch the compressor housing. If your turbo has been fine for years and it starts to leak. Ok, back to the topic of the leaky turbocharger. By the time you notice its leaking there is not much hope for a cheap rebuild. For a true seal, the best set-up is two gapless rings in separate grooves. A lot of those cars run 6 bar of oil pressure, low turbos, and sump pumps. This is very popular in the Porsche cars. Or you can stack 2 rings back to back then offset the two gaps. Run a piston ring with a labyrinth lock for the gap. How many of these will blow out that seal? NONE!!! Next seal is the gapless ring. Things that it does not like, high crank case pressure, low perched turbos, too much oil pressure. Most popular is a single gap steel piston ring. Now, there are a few different types of seals for the turbine shaft. There are still carbon seals uses today though. You really don’t have to worry about those systems anymore. That in return would pull the oil out of the turbocharger. Carburetors would have a high vacuum on the compressor seal. The carbon seals are originally for draw thru carburetor systems, low mounted turbos, and high pressure crank cast systems. Some have carbon seals on the compressor side. Just about all seals are steel piston rings. First off you didn’t blow the seal out of your turbocharger. OK, so I figured I would write a post for you guys on this one. The next words are usually “I just need my seals replaced.” Hummm, no. When you run a turbocharger rebuild shop, you hear these 5 words a lot. Published by Tim Scott on “My turbo is leaking oil.”
