Chaning oil feed gaskets for stock seq
Ok, ive pretty much figured the smoking and bad smell in my bay after boosting is leaking oil intake gasket or oil outles gasket....i can see a flange from the top of the engine bay looking at the turbos from the passenger side...whats the best way to change this gasket and where is the other flange and pipe located? anyway i can get to these without taking off the downpipe or removing the turbos?

well i was thinking bout cutting my own gaskets from gasket sheet? good or bad idea? should i coat them in rtv before installing? any tips on the installation...havent been under the car to investigate yet but i was hoping to only have to remove the engine tray and get it up on jack stands....will anything else need to come down like subframe or dp or the entire turbo setup?

Oil feed or oil drain?
The oil feed is on top of the turbos; a pair of banjos connected by a steel hardline. These are easily accessed by removing the y-pipe.
The oil drains are two pipes; one attached to the underside of each turbo cartridge. They extend from the turbo cartridge to the engine block, just above the oil pan. They can be a test of patience to work on as there is little room but the gaskets can be replaced without removing any major components from the car. You'll need to get creative with 1/4" ratchet extensions though.
The oil feed is rarely a problem as it uses steel fittings and copper crush washers. The drains on the other hand often leak due to the coating on the gaskets cracking or hardening from age. I would use only stock Mazda gaskets here. No RTV is necessary.

Good luck with those gaskets. I lived with a leak forever because I didnt replace the gasket when I replaced the turbos. I spent a couple hours one day trying to replace the gaskets but I know when I have met my match and quit before I got anything too bent out of shape. It would probably be best to remove the turbos to get to those gaskets.
You shouldnt be smoking though if its an oil return gasket leaking, that would just drip on your garage floor and coat the underside of your car in oil if it was really bad.
