or you could do away with everything complicated you have on there and put a single vent from the head to the crank case and not have any breather issues.

The issue is that the crank case cant vent sufficiently, its been discussed at great length in various threads and proven by many individuals.

Thanks Risking, exactly correct - I was only trying to show an easy way before engine loss or failures without pulling head, blocks, rubbish apart

If this is so well known, why couldnt 5 of the top tune shops weve been to fix our problem in four years?

Also where is all the skyline's doing Hillclimbs, Supersprints and track days.

If this system works so well on its own, come do Bathurst hillclimb at 26's, in road rego'd car on fresh DZ03's.

Cause ours couldn't, without filling the catchcan. One breather doesnt work for us on R32 or R33

The faster you go, the more it breathes, the better it will pump - I like it in the sump. (Note: R33 engine - spanking - brand new - still had same issues before front pipe added)

As far as being discussed before if you had of looked - reasonably new member to site when we joined the site didnt find this thread - already over some comments eg warnings from whatever, anyways all the best have fun to all. GTR R32 Australian Hillcimb champ 06 and 08, 2nd 07 R33-09 watch this space November. While you are home not competing keep an eye on NSW Supersprint Championship 09 - great fun!!

Also they cant vent from rear of valve cover or front when it is full of oil - hence the reason front and rear breather!

Sorry Brad, Just had a quick look on site and could not find any of your times to substantiate you claims

Please advise?

Our R32 - (full rego) is running 296 at all four - never had the head off or sump from factory does 1.06s at Wakefield on Dz03 (M), 1.45s at EC and 1.18s at OP our R33 has had extensive work by previous owner in QLD, all re-done, as most people know - cant say where from, but now running a safe 398 at all four at 20 psi at 7,680rpm. EC 1.44s and 1.16s at OP (full Rego) Dz03s ®

PS no oil in the sump stops the pump!!

all right you too....not much point having two of the very few people racing skylines arguing over very little, the world would be a better place if we could work together to get other people to the track not taking shots at each other.

Brad, Stuart has been running NSW hillclimb and supersprint champs for years with great results. And won the Irace meet we are talking about in this thread.

Stuart, Brad has been tracking a couple of sports sedans gtrs for years, and recently been racing and winning the MRA races run under AASA. And works at one of the few import specialist workshops.

So can we just leave it at that?

thanks for posting your solution to the RB26 oil system problems stuart. it's always good to see different approaches to the same problem.

basically the real solution is dry sump. in between standard at the bottom and dry sump at the top there is a lot you can do. baffles, enlarged sump, swinging pick-up, cam cover baffles, various oil pumps, external oil pump, external head drain to sump, sump vent, and the many different catch tank/breather systems.

personally I the old engine was ok with moderate power and a few of the tricks in place. new engine has trust extended sump and pick-up, mines 3 level cam cover baffles, ported oil returns when engine was built, small oil feed restrictor to head, big catch tank venting to atmosphere, oil pump with reimax (nee reinik) pump gears and most important giant size oil pressure warning light and buzzer in case none of that shit works!!!

My apologies.

It wasn't really meant as a shot at Stuart but when I re-read it it does kinda look that way.

Needless to say any skyline out on the track is a good thing to see and if his found a simple solution that works for him then go for it i say.

I personally went dry sump a while ago for a multitude of reasons, filling catch cans and having drains/breathers everywhere was one of them so yeah I do understand the frustration you would have encountered before trying the breather system you have used.

My quicker car has done a high 4 around wakefield a mid 15 around GP, 45 flat at south and yet to run at the creek in the dry unfortunatly.

The grey car sounds very similar to your one, but when we tried putting it on slicks we ran into a world of pain with the oil system.

Are you coming out to the next MRA round at wakefield stuart??

alot of the guys run both series. would be great to get a couple of GTR's out the front of the field and provide some good racing.

for those interested the IRS from oran park will be televised again on one of the fox sports channels tonight. Inside speed or something it was called.

Applogies accepted and given, I may have also been a bit short!

I've got two of these damm things, anyway more than happy with both, just finished some suspensions mods on the R33 ready for next meet - yet to run Wakefield in R33, expecting it to shine over R32 times there.

Had a look on AASA and (MRA only came up bikes) yes got one (GSX-1300R) but dont have time, with 32 and 33, as prepping for final 2 rounds in supersprint series and Aussie Hillclimb C'ship.

Some more info on AASA would be appreciated, as could only find licence and insurance info (not calender) ie for Wakefield - dates, expecting similar times from 33 now on Dzo3's, hopefully we will be able to provide some very good skyline racing.

PS Wanted 18 x 9.5 or 18 x 10.0 inch rims (x4) to fit over AP Brakes on R33. Lenso D1R's don't fit / shame as they looked good!

Dont forget IRS next round on Calender TBA 3-4 October then to Oran Park South Circuit 13-15 November!!

Can someone record the show and out it on youtube plz? I dont have foxtel

[Risking]

we had a similar issue finding 18's to fit over the 997 cup car brakes.

The 380mm rotors make finding wheels a real pain in the arse.

We've currently got 18*10's front and rear in volk. And have a pait of Mesh BBS that just clear them as well also 18*10

No, didnt know about drive day - so we entered for Matara Hillclimb Round of the NSW State Hillclimb Championship.

Took R33 to its first hillclimb, must say, was impressed - ended up with a 37.86 , smashing old record by nearly 2 seconds and 2 10ths off fastest tintop ever. 1st in class and fastest tintop - good weekend.

No doubt drive day would have been great fun, (how did you go?) will get there soon, schedule is 1st Nov Aust Hillcimb Championship Victoria and 2 weeks later Aust Supersprint Champs at PI.

Cheers
