I'm a few months away from my oil change but I'll have my mechanic install the ruff traps and check valves then. How much should I expect this to cost for installation?

I wish I could do it myself but I don't have garage space to do it.

So I bought the RUF kit a few months ago, check lines and P trap tubes, to install myself. P trap tubes were a piece of cake but I was unable to install the check lines with the engine in and mufflers removed. So I ordered a set of check lines from forum sponsor Kevin at Ultimate Motor Works and sold the RUFs. Kevin's were not easy but were doable in the end. When I emailed RUF they stated that they always remove the engine to install the kit. I am guessing there have been some on this forum that were able to install the RUF check lines with the engine in and hats off to them.

You got to be kidding me! Remove the mufflers - okay but the engine? It will be interesting how I time this install.

Other than the ruf P-Traps - the braided oil lines and check valves/washers in the picture above I posted in the box were useless for me and my mechanic. I had to order the turbo kraft check valve kit. I guess I can try to sell the items in the picture above except for the p-trap (hard lines). How much labor cost do people think the check valve installation should cost? It was $$$$ for me. I guess I DO live in the land of the rising rent.

I cannot see the need, to drop engine for this. I’m thinking a better, more reasonable mechanic?

I seem to be getting a puff of smoke now and then. Not on start up but after I've been driving around then in slow traffic. I noticed in these cold temps (and installation of check valves) my temp gauge shot up much faster than normal in standing traffic - went beyond 9 o'clock. That's unusual for my car. Could the cold temps be messing with the thermostat to the front radiator?

If you didn’t install these, are sure they’re done correctly, I might be a bit concerned over temp changes, assoc. with the work being done. Don’t see why a correct install would change the rate/amount it heats up. If you can assure it’s plumbed correctly, then hopefully it’s just an issue with float in tank. If you haven’t manually calibrated (bent) float assm. then do so. It takes a lot of guesswork out, and is nice to have it correlate with dipstick.

This is how we have done the check valve in the factory line...we cut, modify, reweld the nut and then flare the end of the line so it looks factory....

FWIW - oil was leaking out the right side turbo. Got it fixed gratis. As I understood it there was a steel washer used instead of an aluminum crush washer on one of the oil pipe fittings - not 100% sure on that though. Now car has been getting detailed for the last week - always helps ending the water drought

So best place to buy is TurboKraft?

Kevin doesn't do this anymore?

Been through this before probably just the filter...... but it would be nice not to torque it "just right" for it to work.....but it seems like a lot of work to install the check valves.

But I can't believe i messed up the filer torque....i just changed the oil......and now it smokes......and i've done it wrong once (most everyone does on their first change) and then correctly many times thereafter.....i guess i did it wrong again.
may just try a new filter perhaps the valve in there not working (of course we talkin Porsche brand only)......with the dry sump i think i can remove the lil guy w/o oil going everywhere.....is that right? dont want to discard the new 20/50 mobil V.

thanks
joe

What exact filter did you use? Porsche now has a Turbo-specific small filter for the 993TT - I have a used on which I am going to cut apart to see what the differences are, once I get to it.

OMG ya know I've heard of this. Perhaps that's it. I don't have part # for one on vehicle (that is until i remove it ) But I did just order one from Sunset Porsche $25 delivered (best i could find) part # 993-107-203-05......i think that is accurate. let me know if you think it's not plz

oh and can i remove small oil filter without draining oil? or just drain a lil? i want to save that oil since it's new and I put some break in oil in there with even more zinc; just a lil.

Thanks
Joe

I recently purchased supply lines with 996 check valves from Kevin.

993 107 203 05 is the correct part number for the small filter. I believe it is now the same part number for all NA and Turbo 993. From the TSB: "Once existing stock of the small oil filter, part number 993 107 203 00 is used up, only the small oil filter, part number 993 107 203 02 will be available" This was from 1995. Since then there have been several iterations and the correct number is 993 107 203 05.

Yes, you can remove the small filter without draining the oil.

Thanks!!!!

still scratching my head as to what I did wrong

but I will try the new filter and hope for the best

If that doesn’t work I will contact Kevin

in the meantime I have done this (pic) I remember reading years ago this is what PORSCHE used to do for the track in racing (park em with rear up)
