Recently, one of the interns at work upgraded his K04 Volvo Turbo to a K05. Volvo's are new to me and although not a DSM I can appreciate anyone who is a car and turbo enthusiast. So he got a used K05 to upgrade and was just going to put it on the car as it was until I convinced him to look it over. He bought a very good rebuild kit and we tore the turbo apart together. The K04 and K05 turbos are basically a Volvo modified MHI TDO4.
After a good clean, and inspection I went to assemble and grabbed the hot side oil seal to put on the shaft and found this:
The seal has a step to it to help lock in oil!! I have never seen these before and started doing some research. They are called step or labyrinth oil seals. Such a simple concept but you won't find these in most rebuild kits. I found this company on ebay and although ebay reputation is usually related to Chinese related products, these guys are in the UK. While I have a 14B and 16G apart I may go with this upgrade which for us daily drivers should in theory be worth it.
Anybody have any success or failures on these step oil seals?
