Hello. My oil return lines seem to be seeping a little oil at at least the turbo connection. Is it worth trying to replace them with turbos on the car? It doesn't look super difficult. I'm just worried about the old gasket's being baked on the turbos then trying to scrape them off with no room is all.....

 

Just the front line is seeping. Rear is dry and looks like a piece of cake......

 

Yeah, rear is super easy, the front one can be a bit tricky on the car but it's doable. I would make sure to have 1/4" drive tools to do the job, that can get in there properly and fit well.

Also handy is a 12mm socket with a universal joint built-in, that can really easily get in there.

Get new gaskets from Malloy Mazda, they're pretty reasonably priced. Put a THIN coat of grey RTV to help them stick in place during re-installation. Let the RTV cure, then fire it up and go for it.

The only thing that might be in the way is the turbo control actuator, if push comes to shove you can unbolt it and push it out of the way. The front of the line where it attaches to the block might be easier to get to from up top, not sure.

Ok, I'll go for it. Just need to get some longer 1/4" extensions.
Those are 12mm bolts then?

Thanks.

 

I would just recommend pulling the turbos and servicing all 4 of them... If one is leaking, it's only a matter of time for the others. This thread may help:

hmm. Maybe I'll just wait and go single. It's barely leaking, but leaks drive me nuts!
Thanks.
