Anyone have positive or neg feedback on this product and their check valves? I found a few scant postings about them, but no one with long term experience with this product. my wrench is recommending them for some oil leaks found in my turbos. No other clear source of the leak was discovered, turbos were rebuilt 3 years ago.

How funny is this! I just emailed TurboKraft as still I have some leaky turbos while being parked for some time my car. He replied me quickly and explained in detail the problems and how they fixed with their kit. They also offer a oil return kit with check valves as well if the oil feed lines isn't enough. I'm ordering their oil feed turbo kit.

A thread I made about some issues I had in the past, but still chase me but in minnor % of leak.

I have had them on my 1996 TT for over three years and have had no problems with the check valves and lines. Good product.

For those who has this kit installed for some time already, prior installing this kit I presume that all you had leaky turbos or/and smoke at the start up?

If you already have the check valves installed just ask him for the oil return lines for 993TT. Cost is around 170 Euro for the pair + shipping
Perfect fit and great service.

They also sell a complete kit with check valves which is very reasonably priced IMO.
Good luck.

I had the Turbo Kraft oil feed and return lines installed on my 993TT for over a year now, so far so good!

Feed lines been on mine for at least a decade, and I never have smoking so didn't bother with the scavenge lines.

If you buy Parts from tk fine, he just gets them somewhere else & marks up, but ALL the locals here know he's a FRAUD, he has ripped more people off here for years, including me, he signed & lied on official docs from my CC Co when I challenged what he did for 36 hours of work, For a DYNO TUNE! YES 36! He had my car for two Months & another tech had to put back together everything he f*cked up, He up-sells & spends all his time on Pelican forums, I'm surprised he's still in business?

I'm in a process of doing a turbo conversion on my 3.8l engine.
I ordered check valves from
http://www.5150motorsport.com/exhaust-19/#
$77 each and will be doing the plumbing myself. I'm sure the check valve could be installed with the oem feed line.

If you're talking about the 993TT OEM feed lines, they won't work with these check valves. They need to be the flexible lines to work. The space to plumb them is really, really tight. They need to angle with the 45's and then loop through tin/grommet into bay, then into the valve. In the engine bay you want to use 90's or 45's to route line away from spark plug boot. Great price for the valves though, if you can actually get them for that. Good luck
