It was suggested I go to 15w40 Royal Purple, but that was before we knew the full extent of the damage.

The general concensus is the oil starvation was caused by high cornering G-force. So, ironically, the coilovers caused this damage because without them I wouldn't have the cornering speed I do now.

Brian has some contacts who have either had this problem or are having it right now in race cars. Oil pan modification is probably what is going to be needed to add more baffling.

Cool reason but terrible result. Sorry to hear and looking forward to see what you come up with as a solution.

What bearings were you running?

A Swedish site sell these;



Sadly, I can't remember the url...
Good luck with the rebuild.

[Zappo]

I like that. Looks like 4 flaps to control the oil flow to the pickup.

Time to start searching the net.

Stock Volvo I believe. I don't see anything special in the build list.

This is the pan we have prepped for our 850 Race car... After 2 motor failures at Oregon Raceway Park, we are pulling out the stops for oiling short of doing an accusump:



Ishihara-Johnson Crank Scraper with Teflon:


And an accusump... We went with the larger model but a smaller one might be able to be mounted somewhere inconspicuous and used with their electronic valve pretty out of the way.

And by my first accusump comment, I meant dry sump.

Hmmm.... I wonder if this is something I should also consider, or if it's really only an issue on the track.

I wonder if you can buy those flapper doors as a universal kit.....

Hopefully this will resolve your issues.

If you're beating the motor often, 15w-50 ...

Sorry to hear George.

Since your car is street only, you probably would never encounter the problem. It is really only an issue with higher g-load cornering, so only cars on the track would have the issue. It is only when I tried to increase my cornering speed that this happened. Never had the issue with the previous suspension, and I was using Monday's practice day to setup the car to do turn faster.

If I bought the slicks like I was thinking last year, this issue would have happened even sooner.

Anyone remember those 'rear camber spacers'?

Cosworth pan.

Sucks George. Must be frustrating. I'd probably run Rotella before I ran royal purple.

[lookforjoe]

^ Did you get that off CJ? Looks good!

[Zappo]

I took his picture and posted it here.

I don't have the pan or anything. If I did, I would be far more excited.

I just posted it here as another example of what has been done.

It is frustrating that I am now running into race car problems. I guess I am pushing my street car into race car territory.

I am a pioneer now, at least in the US.

[gdizzle]

It's good to be on top. Props to you.

[Zappo]

Well, I hope people will pay attention to the thread and learn from my failures so it doesn't cost them the same money I am putting out.

^Where can a small guy like me get a cosworth oil pan? or would it be cheaper to build that trap myself?

[andyb5]

Are those hinges welded to the baffles?

[Jardim]

Looks like rivets where the screws would go.then weld

[gdizzle]

Spot welds.

[andyb5]

Look at the bottom left plate, in the middle of the plate, above the tube opening. Sure looks like a hinge
