Turbo oil leak

Fixing oil leak on turbo oil drain.Found some nice braided orange hose 5/8" id that fits perfectly from napa.The 90 degree elbow will be resealed with teflon sealer before I screw it back in.I found a new brass ferrule in my parts stash and will put it on the pipe.Should I put sealer on the connection at the ferrule?Any other tips? Thanks.

I have never sealed it there, but its good to re-tighten the hose clamps after a few heat cycles.

No teflon tape needed on a ferrule fitting! Or sealer of any kind.

The Pipe fitting does need sealant of some kind but teflon tape is a second or even a third choice.

Oil leaks on the turbo oil drain fixed.Car runs perfectly and boosts well with no oil smoke out the tailpipe.After a 3 mile test drive with moderate use of the boost it pushes oil out of the dipstick tube.Rings,valve guides?A used right side head was installed by previous owner after dropping the #5 valve seat.I don't think he had the used head checked.He just installed it as is.Is it possible that the oil is overfull and the dipstick or tube has an issue?I have a zero mile engine that came with the car that was built by a long time corvair guru(Jack Hilton).Should I just swap engines?Thanks.

The factory turbo bronze guides are well past shot by 25K miles. That will alone will allow a lot of blow by gas. Watch your air cleaner and see if it gets oily after repeated boost.

If the worst thing your present engine does is push oil out the dipstick, think about cutting off the bottom of the dipstick tube before doing anything else, as that is a relatively common thing that can happen. If modifying the dipstick tube takes care of it, drive on! if it does turn out to have an excessive amount of oil consumption, then put the replacement engine in.

Good point about trimming the dipstick
tube Kevin. I thought everyone knew
that trick but maybe it hasn't been
brought up in a while. I guess too many
new owners these days although it may
be tucked away in the FAQs.

Trimming the dipstick tube inside the oil pan sounds like a good idea.I will report back after I try it.Thanks.

I read that once the pan is removed you take a phillips screw driver and insert in to the tube then bend back and forth the tube should snap off at the block , it worked for me.

Broke off the dipstick tube (after pulling oil pan) flush with block this morning.After a 10 minute road test with boost it still pushes out raw oil out of the tube.I am going rig up a blowby hose from the tube to a modified oil cap with a fitting for the hose.I will report back after this is done.

Ronald.... that will do no good!

1 Make sure the orifice at the carb is open...

2 With the mod'd filler cap.... run that line to a "catch can" [ vented ] or just directly overboard...

Will a "burp" hose from the oil cap to a "burp" container stop the raw oil from pushing out of the dipstick tube?

you already have a basically open half inch pipe running from the crankcase to the air cleaner

Yeah.That what puzzles me.I am going to go over that complete pipe/pcv system again to make sure there are no restrictions.
