Hi all,

Trying to narrow down a decent place to put an oil drain on my MPi build. Any issues with putting it here in the gearbox?

It would probably be ok, but how about through the engine end plate  in to the timing chain cover? It's how breathers were done on inline engines and should be easier to fix(flat steel plate) and keep clean from swarf (access both sides).

Im fitting a DSN timing chain cover, Ill mock it up and see if Ive got enough reach to it. The turbo sits lower than I though hence why draining to the gearbox seems a straight forward option.

The cover sits higher than I first thought. I don't think it's an option to get an AN-10 on there.

but you might be too low to actually drain.

 

where is your oil level? how much will go up the pipe on acceleration? 

 

loads of places on the DSN cover to drill and thread. you could even mod that breather.

To put it into context, the cam sensor on the back is too high for it to flow out, so you can see where it would have to be on the back plate. On measuring the oil level if the engine is stationary, it would be around 3" below the feed, which is lower than it is on an Evo 4G63 engine which sits 1" above it. It would also give a 7" drain pipe at AN-10 size from the turbo to the fitting on the gearbox.

but as you say. i remember having big oil leaks from the fuel pump blanking plate hence my comment.

 

i think you will be too low.

What's annoying is there's no middle ground. I may have a play again and see if i can get an AN-10 weld fitment on to the DSN cover.

You may need a scavenge pump if you're restricted as to how high you can mount the turbo. Last one I did situated the turbo above the wok, I fed the return to the speedo drive hole. Was fine. So where you've pointed to should be ok also.

Cheers Merv. Showed it to the Evo and Euro turbo boys and theyve all agreed itll be fine for my application.

If the cam sensor is too high I'm a tad concerned you might have worse clearance issues if it's going in a standard front subframe.

true i had not thought that far on. just been looking at the pics if the turbo install.

 

are you going to run a scavenger pump? or just gravity for the drain?

 

places that i would fit it rather than there on the casing are many.

 

from modding the DSN base or cover or even tapping out the dip stick hole and ave a dry lock QC fitting. and then make up a custom dip stick for use as needed.
