Another shot

 

Nice job.

 

I would try to get the head gasket mating surface a little cleaner. Carefully draw a single edge razor held at about a 90 degree angle over the surface.

 

thats on my list for sure. thanks guys!

 

make sure you clay it up, put 2 bolts on the heads and lever down the vavles to make sure there is no contact as they clear the ridges of the valve cuts.

 

Here is my pan and pickup. The pan has no holes for the tray or screen..... Any thoughts? What's the best oil pick up set up? Or will this work for street and some DE day driver/ autocross

 

just put it together stock! all the motors that have raced or helped race, for over 15 years combined have all had just the stock later version pickup. if there was an issue with the stock pan, i probably would have seen one.

 

I asked the same question a while back and did not get a conclusive answer.

The newer style has the advantage of being able to retrive bits that have dropped down into the pan.

 

I used the 1982 older style pan with the screen and later pickup seen in the pic above. Made my own solid baffle similar to the GTS.

The screen is nice because it keeps oil in the sump from being picked up by the 1 & 5 pistons. The baffle is needed to keep the oil in the sump under hard acceleration.

Nothing wrong with the clover leaf design. I just didn't care for the worm hose clamp. Air will be induced if it were to loosen of break.

One thing is for sure, Porsche spent a lot of time and engineering in this pan/pickup. Assemble it like the manual says and it will be fine.

 

Use the old style pan and a 3/8" pan spacer Mark Kibort has had good sucees with a stock S4 pan but just about every body else including me have seen catastropic faliure using the stock s4 pan. I now run OB pan and a spacerand an accusump. In addition to all those parts I plan on installing Greg Browns windage screens in my latest engine. Unlees you can replicate Kibort's driving style forget the stock pan and install an OB pan and spacer its cheap insurance once you start running big sticky tires you will see oil pressure drops on high g turns. I mean turns above 1g ,I pull 1.4g sustained in my race car and I find the OB pick up does a better job of keeping the pick up submerged.

 

NO NO NO NO Mark is the ONLY racer EVER (Scott doesn't drive enough to count) to not grenade engines using the S4 oil pan.....until someone else can have ANY success with it, its safe to say it is a total failure for anything other than "driving miss daisy" street driving

Think about this....our oil pans are maybe 4" deep and nearly 2 feet wide....do the math in your head.....do you think that will work at even .5g...I DON'T

Justaguy is right....the OB setup is the way to go......it just works.....I can't tell you why, but it does..... For racers add the 3/8th spacer for extra clearance to the crank...

73.5 hours and counting on my OB + spacer setup...no accusump or oil cooler...73.5 hours since Feb 2010......on a used $300 engine..

 

I respect you Mark but in my opinion this is bad advice. Stock is fine for street driving even a little track on street tires. But racing on slicks requires an up grade to the stock oil pan. There have been many 928 engine failures world wide due to oiling issues. You seem to be the only person that I know of that can race a stock oiling system on a race 928 with sucess. Which is a testement to your driving style but not a recipe for sucess for every one else

If you start to lose oil pressure the lifters will start to rattle before the engine blows, kind of an audible warning system. If you hear excessive lifter rattle at the track it's time to stop and address the oiling issue. If you hear this you are on your way to an engine failure. Ask me how I know. You should also pull the oil filter and check for aluminium and or copper flakes doing this saved me an engine on my street car. after the first time I ran a big set of PS2's at the track . Thanks to greg brown for telling me to check the filter after I heard the noisy lifters. I had to redo the rod bearings but saved the engine.

Car was a stock 87 S4 with 50K miles on it runnig Amsoil and a STOCK OIL PAN!

 

so an OB Pan is with the screen, and the spring loaded jobby? can i adapt or create a screen for this pan and use this pickup?

 

Get a setup from Mark Anderson, that is what most of us did.
