Gents,

stock seal on exhaust side not handeling the heat and crank case presure - who knows where the best seals are under these types of conditions . There is nothing wrong with the installation other than what i have mentioned .

Any direction in respect to where i can purchase appreciated.

thanks

hey dave i had a leaking seal too and it was from not putting some gasket goo on the front cam cap to seal the 2 little slits in it, the workshop manual doesnt even mention it needs it but its been on every motor ive pulled apart and worked perfect, maybe this isnt it but just thought it was worth a mention.

cant wait to see it out of the track too, i have been keeping a keen eye out for it every meet :P

Thanks for the info - engine dyno'd this week - ust over 1000 hp at 29 lb - plenty left - just the cam seal issue.

yeah. genuine is best. dabs of threebond under the cam caps is a must aswell. you are talking about the camshaft seal? not the valve stem seals?

The standard seals are excellent and never leak on a good engine.

You must have some other issue.

Point taken - may be i do/

Stupid question i know but sometimes the most simple things can be the cause. Are the seals around the right way?

Not a silly question - but yes they are. Bought some HT Vitons today - should do the trick.

Yeah the vitons will be heaps better if you are suffering from external heat issues, they are alot more heat resitant than the nitrile ones! you could also pull the spring out of the back of them and shorten it a little to put a bit more tension on it if it needs it..

      RB gearbox options

      What makes you say CD009 boxes are not as strong as you would think? I've always been told the last revision (CD00A) is good for 1000whp and I have no issue's believing it when comparing one side by side with an RB25 box. Makes them look tiny.

      I picked up an open Center with shafts. I was told the Open shafts will fit a mechanical LSD and looking at them. I think they will work. Will update

      The manual says a lot about the different ratios requiring different shafts. all the Centers are the same but depending on the ratio, this determines the shafts because different ratios need the center to be offset more or less or right to left.

      those 2 sets of shafts will not interchange and if you’re lucky you haven’t damaged anything with all your pressing and bashing you said you’ve done

      Lets play a game - What is causing my oil consumption?

      By TurboTapin · Posted

      Freshly built stroked RB25/28. Motor runs great but consumes a lot more oil then It should. This summer with the heat I was consuming roughly a quart per 1800-2000kms. Now with the cold weather coming in, I'm consuming a quart per 1000kms which is no bueno. I had originally chalked this out to break in taking a little longer then it should, but I'm now around 4000km's on this engine. I think it's fair to say something isn't quite right. Here's the kicker, can't find what's causing it. I've also spoken to my engine builder and Precision Turbo and can't figure it out. Here's my train of thought on possible causes and what I've done.  Precision Turbo - I originally started thinking my oil pressure might be a tad too high for my 6466 Gen2. I took the center cartridge out, and while yes there's signs of oil on the turbine heatshield, it's very moderate. There's also very minor in/out play that concerns me. I sent pictures and videos to precision and they said the residue and in/out play is minimal and they doubt this is the issue. For piece of mind, I went ahead and installed a Turbosmart OPR V2 to bring oil pressure down. Made no difference. Precision is willing to take it in on RMA for an inspection and I'll probably take them up on that offer for peace of mind. BTW. Is it just me or does the turbines inducer's look clipped and not even between each other? I just noticed this now while posting and looking at the picture zoomed in. Might just be the picture...  Rings - Hot compression test and leak down test look good. Compression is 160 +-2psi across the board. I leak down at 16% on cyl 1,2,3,5,6 and 18% on cyl4. Keep in mind I have a snap on leak down tester and they read high (I.E, 15% on my wifes 2018 Sentra with 70000kms). Sparkplugs show minimal oil (Only #4 seems to have a tad). At a quart per 1000km's though, I would be expecting them to be wet. Here's the kicker, I run WMI. I'm thinking what if my compression rings are great, but I have an oil control ring issue on cyl4 and my WMI is steam cleaning the pistons and sparkplugs? I can still see the "Spool" logo on top of my CP pistons. The only time I see smoke out of the exhaust is in the high rpm/load range. So far, this is my main culprit. I'll probably turn off my WMI and go out with the car at spring pressure tomorrow and repull the plugs. Other thing that's strange though is that I have never seen any oil in my catch can. Thing is still dry after 4000kms. Cyl1 - Left, Cyl6 - Right. Valve seals - They're new and I would expect oil consumption on idle, first cold start or during decel. None of which is happening.  Crankcase pressure - I have 2x 10an valve cover lines to a vented catch can. Head drain and opened up internal oil drain paths. I also don't run E85. I've never seen any oil in my catch can. Doubtful this is causing any issues.  Rear main seal - I have no visible leaks, but figured maybe it was my rear main seal. After now having added 2-3 quarts, I would expect oil to leak out the bottom drain channel and/or my clutch to be slipping.  Let me know your thoughts. With winter coming and taking the car off the road until spring, I'm fine with pulling the motor apart but I would hate to take it all apart and the turbo was the issue in the end.
