I just got my oil pan off so I can take it to get an -10 AN bulkhead fitting welded in - tomorrow if I get a reply fast enough (which was a freakin BITCH and a half, my car totally owned me today). Anyways, I need to know the best place for me to get it welded into. I'm sure some of you have done this before and know what location on the pan works out the best. I have to order a new gasket as well; should I get one of those baffles while I have it off?

Thanks,

Just make sure it's as HIGH up on the pan as possible, directly under the oil drain of the turbo is good.

 

A few guys on nopistons just told me I should weld the -10 fitting into the stock oil return hard line; would that be a better choice?? A few local shops told me to plumb it into the oil pan and i believe I read it here a few times as well.

It is better to return the oil above the oil level. Anywhere on the oil pan will be below the oil level. The stock return place is best. If you return the oil below the oil level it will "back up". This may not be a big issue but if your turbo starts smoking moving the oil drain to an area above the oil level would be on my list of things to do.

 

flyin taco, i agree with setzep on this, i drilled and tapped the front cover for my return line. it was very easy and no welding required. my 2cents

 

wouldnt it be easier to just get a T fitting and put it in place of where the return hose comes out of the cooler?

 

no, it has have ZERO backpressure. Mazda put it in the front cover. Use the front cover.

 

what kind of a motor is it. . . i have a brand new 12a baffle plate with two new gaskets. . . hell, i think i have four. pm me if you want it.

oh, and i agree with directfreak. the oil drain needs to be able to freely drain. . . . there isnt much pressure behind it. the pressure from the cooler return line will overcome the turbo's drain and cause back-up.

Check out the link. This is were I installed my turbo oil return line. It has worked for me for the last 15 months. I do have a oil restrictor in my inlet line. Where is oil level line when motor is running?

I did this as well.

Drill, tap, attach piece of pipe. It is literally that easy.

how much is the gasket for the front cover. i assume u took it off when u drilled?

 

You guys did remove the front cover before drill and tapping, Right?


front cover is the best place but you have to remove it to do it. Unless you want shards of metal in your motor.

haha, yeah, took it off to drill/tap

 

I've never had or heard of anyone having problems with using the stock return.
