Hmmmm,
I had planned (and have all the stuff for) a water/meth injection system. Maybe the 50/50 mix would keep the Laminova cores clean? I decided not to install it due to having to find or make the mix when traveling long distances.
Another solution would be to build another intake with more accessible cores. I guess for now, I'll just see how this goes.
Has anyone seen a turbo
without oil in the intake? I only have experience with this one and there was plenty of it when I started the rebuild. However, the vent was plumbed into the intake piping and it was clocked at 4:00 as well. The turbo itself was in great shape. I only rebuilt it cause I had time while waiting for parts to arrive. Besides, I wanted to replace the stock bearing with the 360.
Forgive me for doubting your perspective libby but as a machine designer by trade, it's tough for me to not look for weaknesses, and try to bring solutions before release. I'm not confident the designers of the turbo were trying to achieve a 100% seal against oil leakage - which is what is needed if I don't want the cores getting oiled up.
That said, I'm not sure that a bit of oil would be that big of an issue
Thanks Theman, I just read your post while I was writing this, it seems were both on a similar track (based on my last sentence)
all turbos have oil in them from breather vent....
go pull your breather pipe from a td.. stick it in a jug.. clear plastic with some paper towel in it.. see how it splatters/vaporos oil in the pvc system...
if you see droplets on towel.. decide if too big... then rember the turbine makes it a mist...
but all you can do is try it...
That's why I plan in running my vent pre-intake filter. It may oil the filter but not much should get past it.
When I design the filter box, I'm going to keep the vent in mind and make it so there's a catch area of sorts with a drain on it.
My truck just came with a catch can...a crappy system but satisfied the problem of crankcase ventilation without too much mess. The problem was, it did make a mess...just on my rad and engine. It was at the front of the engine and the fan would blow oil everywhere. Kept it off the ground, for the most part.
I now just run a tube down below the engine. As I've mentioned before, there are no emissions restrictions on my pickup so I can get away with it. I am planning on an oil/air seperator...as soon as I design it. In the meantime, the oily film on the bottom of my truck is doing a fine job of preventing rust.
If you have the crankcase vent upstream of the turbo, you will get oil on it...there's no way to avoid that. You could reduce that somewhat with an air/oil seperator midstream, or like you're doing, pre air filter.
You could put a couple of baffles in the filter box at the vent outlet, (I'm thinking one of those copper scrub pads in a soup can kind of thing), and rig a drain for the collected oil, if you want to keep your filter cleaner longer.
