this is phil's but it's the same, except he used to hard 90 on the case instead of the turbo drain.

Jerry, thanks a million! Exactly what i needed to see.

What pray tell are we doing here? Replacing hard metal tubing with stratoflex?

Is there some reason that this isn't in the 911 Tech forum?

Wear eye protection...Outsch!!

Finishing up a turbo drain plumbing solution with Jerry's kind help. For those curious, this is an elegantly simple solution to the vexing problem of oil return to the sump from the turbo on Carrera turbo conversions. No need for a scavenge pump, or leaky return to the cam cover, or grafting a 930 cam pump. The oil pump sump is right by the drain plug... voila. Surprised Porsche didn' t do this. Jerry has included a list of BAT fittings needed.

I'm afraid I must report you to the administrators of this fopum. Ordinarily I'd not do that, but they've been on my case recently about topics in this forum, so I feel compelled to make them aware.

Just a thought... is it because your a pathetic jackass?

Relax 'Fast Pat' Just move the thread guy. Jeez!

Idiot. I've never reported a thread on this group of fora since I've been here.

The only jackass is the one who didn't understand.

Understand? I bet I understand u better than you do.

Whose the idiot? Someone making constructive comments or some tool who doesnt have anything better to do than sit at their computer cruising the board making completely worthless remarks.

That would be you, Hermeine.

OK Pat, as much as it pains me to admit it, you gave me a good laugh to finish up what has been a crappy day!

Oh yeah, and this is the first and only time (probably) I will ever agree with you...this thread must be reported to the administrators...maybe even with a recommendation to ban those who stoop so low as to clutter this Off Topic Forum with any sort of factual or Porsche related technical insight...

This REALLY must stop....where are the Moderators when you need them!

Good one Pat....

Get a life pathetic excuse for a Pelican. Thanks Jerry. Unsubscribed.

Thank you....

Uhhhhhh.... and now back to our regularly schedualed programming-

Hey I have a question about your turbo return line project.

If the return line dumps into the bottom of the case as it appears it does in the photo what about thermal pollution into the engine?. Would this set-up raise engine temps and also possibly risk sending metallic debris into the engine in the event of a turbo bearing failure?

I could just be misunderstanding the pics and the short explaination-

I have always wanted to build up a 2.0 turbo engine so this intrests me as I have heard of this being done but don't know any specifics.

cool project by the way, and nice hardware.

Jeff

yo jeff-
it will raise engine temps no more than would any other turbo oil drain system. The oil will be hotter because of the turbo, the only difference is it enters a different place. It gets circulated around, so total temp difference=yes (turbo=hotter), local temp difference=moot point.

a turbo bearing failure is the same story. metal will get in the oil , oil will go into the motor. small pieces in this scenario would be sucked into the oil pump and that is BAD news! but no worse than a turbo failure running any other type of oil drain, it's just bad news period for the motor to have metallic debris in it. Any big pieces that make it down that big AN line will not enter the oil pump as the mesh is too fine.

When you do that small displacement alu case turbo, I wanna see ! An old 930 manifold, 2.2 heads and low compression, as well as a megasquirt.....m&k exhaust, small junkyard (rebuilt?) turbo.....cheap and too freakin fast for its own good.

The case drain is a great idea, guys! Also it's not just a gravity drain, that pump is obviously generating a serious vacuum right there so oil will really flow through the turbo...:cool:

returning it to the cam cover is what really raised the temps.
it was amazing how fast it got up to 200, maybe five minutes.

Sending it right to the pump to send it back to the tank more directly took it back to it's normal warm up time of about 15-20 minutes.
If by chance something went through that line, there's the pick up screen on the oil pump.
Hopefully I'd know it if the unit failed.
