Anyone got one of these for sale?

Rob Edwards

I got a good used one from mark about 4 months ago.

IcemanG17

do I have one..................YES......is it for sale.....................HELL NO!!!!

However Anderson has lots....around $150 or so...money WELL spent!!!! It will cheaper for Adam since he only needs 1 piece....for those "retrograding" you need a few parts

1: Cloverleaf thing shown (with 4 bolts you will have to tap)
2: Mesh screen and bolts
3: new pickup assembly (with rubber spring loaded thing)

I have one of those I can sell if mark doesn't.

Why did it break?

IcemanG17

my guess is removal error?

JB weld is perfectly suited for this application LOL

Any fluid dynamics guys out there? Why does the OB pan pickup work so well?

atb

Wish I could take credit for the break, but it was that way bolted to the bottom of the pan. I removed the screen and was suprised that it was broken. Even more mysterious is that the pieces broken off around the cup and from the lower left clover leaf were no where to be found. A little ominous in that the pick up does not have a screen over the mouth like the later models do. Not really a stressed member, so I don't know why it's broken. I can say that the engine overheated (major) and that the plastic is very brittle. Thanks for the back up Mike, I'll see if Mark has one ready to go.

any data to say it does work any better than the later styles?

GlenL

Huh?

There's no real results on this. Just exuberant supporters. I removed mine and upgraded to the later style. I think the early style it's worse than the S4 style for sucking in air or foam.

The S4 has a screen and is closer to the pan floor.

The early style is dependent on that rubber fitting being tight. Air will get under the lip of the cloverleaf and has nowhere to go but into the engine.

With oil sloshed in the same way, under acceleration, braking, cornering or a combination, the edge of the leaf is exposed to air before the S4 pickup is exposed.

Anecdotal stuff is fine for the anecdote creator. Hows this: with an S4 pickup and full I-J windage set I've eliminated oil ejection. Prior to that I spent years fighting to keep oil in the engine on the track.

I have the oppurtunity to go either way. I could just throw the stock '84 pick up/pan assembly back on (P.O. had a GTS baffle installed), but would like to go with the O.B. set up. Seems a lot of folks have had decent luck with the set up. Together with a pan spacer (thanks Mike), I'm hoping to replicate Bryan's consistent running in the Estate.

I do like the old screen cover over nothing and over the GTS cover. I've tried them all. I'm not sure why they even bothered with that last one. It did nothing for me.

Two critical variables are the tracks the cars are run on and the driver's individual styles. I recall Bryan saying he shifted low, like 6000 RPMs. That's an important factoid.

Unfortunately you and I have had drastically different results with the OB pan...you did have an engine failure using it....and I have not "yet" and I will continue to move forward with the OB pan + 3/8th spacer setup just to determine the limit of its lifespan....remember you only ran the OB pan, not the combo I run....However I can personally document 3 failures with the "S4" pan....plus more through others

As to the strength-weakness of the IJ scraper.....I can't speak of experience...Sean had good luck with it in his street car...not the same in his racer....which didn't appear to be the scrapers fault

The one thing I am 100% sure of this.....I have MORE track time in the past year than any other 2 928 racers combined....running a used engine with my OB + 3/8th combo.... 49 HOURS...real on track hours....at race pace....on a used $300 engine.....

I know I am sounding alot like MK....but the DIFFERENCE is this....MK loved the S4 oiling setup...that has grenaded more 928 engines than any other...he is the ONLY one to survive on track with this setup.....(remember I tried this...it didn't work) The "plan" I speak of works in my racer and is currently working in Seans Widow....nearly 30 hours in it to date....those boys in the great white north take advantage of good weather and put nearly 4 hours per day on their cars......

More proof......my racer has been driven by more drivers than any other....plenty of different driving styles in play....street tires, R Comps...you name it.... some will argue that driving style accounts for alot in engine damage due to oil starvation....I agree.... Ask MK, Anderson, Sean, Jeff, 3 employees from the race shop or Dean Thomas (top spec miata racer) about my racer....they all have driven it.....at thier race pace..... I welcome any 928er to drive it.....the only "rule" I have is don't exceed 6000rpm or so...since its not making power past 5500 anyway....

So Brian, How do you really feel about the OB pan?

I have to agree the OB pan with the spacer seems to be the best set up for oil control that I've found so far. But what do I know I've only blown 2 engines on track so far and only track the car about 50 hours a year.
Last engine had the OB pan, pan spacer, and IJ crank scraper but failed due to a dropped valve which probabally was the result of an over rev due to a 7,000 RPM setting in the ECU. That engine had about 40 track hours on it so was a vast improvement over previous engines which only lasted about 10 hrs.

I put about 20 hrs on this engine, ON Track under race conditions with OB pan and spacer but I now have an accusump installed in addition to the OB pan and spacer so my results from this point foward may not be consistent with running just the OB pan and spacer.

Thats why I asked for a professional opinion, I don't really know what the hell is happening in the oil pan under extreme driving conditions I only can speak to what works for me in my car on the race track.

Roger stated there are still 50 of these things in Germany. Price is heap cheap, contact him if you want to be pleasantly suprised. I inquired with 928 Intl about a used one and got a shipment confirmation for a response, so I guess they had them in stock. At any rate, if you can wait for one to come in from Germany, you won't be paying much of a premium for new. If you can't wait, International has them.
