I have also looked at UMW kit. But they will take a long time to get...


Any others?

have them(turbo kraft) on my 993tt w no complaints.

^^^^^^^^SAA!!!!

I've have an extra set of Ruf Check Valves, my car apparently already had a set installed when I went into install a set of turbo oil return lines.

PM me if you're interested.

I have had the TurboKraft check valves installed on my 993TT for a few years now and report no problems at all. No exhaust smoking after storage for the winter too!

Did you buy/install then after having smoke at the start up problems? if so, did they cure the smoke?

I just installed them but it will be a long time before I can test them.

I had the TurboKraft check valves fitted to my previous turbo as a preventative measure and my current turbo had the same ones fitted by the PO for the same reason. TurboKraft seem a good bunch to deal with and the product feels nicely made.

Just placed the order for the oil feed check valve kiy from TurboKraft



Now I'm still looking for the oil return lines with the upside down "P" trap design.
I have not found anyone that makes them.

Someone sent me once a link/photos of those lines you talk about, and he used to reproduce them.

Turbokraft also sell those return lines but with check valves. I wanted to try firs the feed line turbo check valves kit first if not enough I will do my own return lines, that's piece of cake.

RUF? They have P-traps that are available. That's what I'm looking at. Made from a solid oil pipe not tubing. There was just a thread on all this but I won't complain it's good to see some action in this forum.

Can you send me a link for the ruf lines?

I didn't see that they have return lines on their Web site.

I will cehck for that link.

No they don't have it, but I think I have their email and they sent me the brochure for both kits. I can forward that to you?

I think only Kevin and RUF are the only commercially available return lines, with inverted P-traps. Turbokraft only has the oil feed lines, with the check valves. There's no check valves in the return lines, only the inverted traps.
