rerb Posted March 1, 2021 Posted March 1, 2021 Hi, I've been plotting out my oil lines for my turbo and have the feed all figure out. But I'm a little confused on the drain. I'm pretty sure mine's too high for gravity drain, and I'd be more comfortable with a pump anyways. Know a lot of people recommend a mechanical crank driven pump, but those are too expensive for me right now. So my question is, with one of those $50 electrical pumps would they be strong enough to pump the oil upwards into the clutch cover oil fill plug? I see a lot of people run them to the sump but I'm not sure how that would work with static oil level. Another question is if I could drain it into an oil cooler line with a split or a 1 way valve, or will engine pressure override the pump and result in me having 2 feeds? I know a crankcase breather is important and I see they make some from the oil fill cap, but I don't see any other place for one so I'm not too sure where my drain would fit into the equation. And catch cans aren't necessary for a drain with a pump if you run the pump on an independent circuit for few seconds after the bike is shut off, right? Any clarification would be appreciated, thanks. Quote
Blubber Posted March 1, 2021 Posted March 1, 2021 Wait...you think your turbo is too high for a good gravity drain? Maybe a picture will help. Quote
clivegto Posted March 1, 2021 Posted March 1, 2021 Facet oil pump one way valve, start oil pump before starting engine you will hear it clear its self. Quote

Gixer1460 Posted March 2, 2021 Posted March 2, 2021 Although I don't have one myself (which I may do with the next iteration) and use a mechanical pump, any drain back / drain down in feed lines will bypass the bearings and leak into the housings leading to a degree of start-up smoke. A little sump / catch can allows this to drain away and be pumped away on start-up so IMO a worthwhile addition. Quote
no class Posted March 2, 2021 Posted March 2, 2021 ....be aware that a solid mounted catch tank / welded tube on tank body ....will see alot of small harmonic vibrations that can lead to cracks and well....eventually failure . Quote
clivegto Posted March 2, 2021 Posted March 2, 2021 I run 14mm id pipe to one way valve to 8mm id pipe then to facet pump mounted under the sump then returning into the top crank case. Quote
Reinhoud Posted March 4, 2021 Posted March 4, 2021 There are people who did the scavenge via the oil pick up, I think with a one way valve in between, but I don't know the details.. Quote

Yep, that's brilliant. I was wondering what use that plug could serve. Quote
