m35a2 oil line bleeding

[Katavic918]

I searched around and couldn't find anything on the topic so I guess that's a good thing. I'll be removing my turbo in order to drill the manifold for a pyrometer install. (I know I don't absolutely have to). So my question is, when I reconnect the oil lines is there anything I need to do to bleed the air out of the lines or get oil into the turbo? Thanks for any help.

No. Oil pressure will immediately push oil through the line and purge any air. You may want to replace the copper seal at the oil line fitting though and you may want to use a new gasket between manifold and turbo.

The only special thing that should be done is when installing a turbo that has not been run for a long while or is new is to pour some motor oil into the oil inlet side so it has lubrication immediately for start-up until engine oil gets there. This is not necessary in your case as Cattlerepairman states.

Gasket? Copper O ring? Where are these?


Don't you just unscrew the flared oil tube and call it good?

Well When you remove the turbo as you stated you are going to, It's just good policy to (at least) examine the seals and gaskets, and replace them IF necessary.

Ahh, never thought about the turbo to exhaust manifold gasket. I thought they were talking about the oil line. Derr

I'll replace the manifold to turbo and turbo to exhaust gaskets. I think the oil lines are flared fittings with a fitting attached to the turbo with a gasket in between. I won't be replacing those gaskets at the moment since I won't be removing them. Thanks for all the help everyone.
