Could just be a bend sharp enough to partially collapse a hose. They are formed, and at least on of them has a 90 in it

I don't think oil pressure is the issue - but if I did I'd be saying don't rive it till you are sure it is good.

You know the old saying "don't fix it if it aint broke". It comes from real experiences. I'm not saying not to do maintenance or mod, but when you do work on something and it stops working you should know where to look.

Great. I'll take a look at those.

Totally. That's why my mind went to the headers, as they were the only thing that got worked on.

This wouldn't be the first time though that I put on a new part and something else happened to go wrong at the same time. Perhaps from the car sitting in the air without being run for a longer stretch, perhaps something else got bumped during the install, or perhaps the new part ended up putting extra strain on something that was already stressed enough.

Perhaps you blown up my guess, but I took:

to mean you had worked on or with your oil cooler - which was my whole point. If not that makes it far less likely it the problem. Rereading I believe that the oil temps were already hot before you messed with it.

Water cooled AOS? If plumbed as in the diagram it should have made no difference.

Oil cooler was never touched. Oil temps were normal in the past.

Regardless, I think it's a good thought. One that has been shared by others among my racing friends.

Yes, water cooled AOS. I believe all was installed correctly... and I think if it was done wrongly it would have been pretty obvious from the start. But worth a thought.

I'm working 8am to 1am ish every day this week and hoping to run SCCA Time Trials this weekend at High Plains Raceway. Had a couple friends come through for me... picked up a spare stock oil cooler as well as a complete oil cooler setup with a 25 row Mocal cooler. Dropped it all off tonight at a good shop -- hopefully they can either find an issue with the stock cooler/lines and/or install the Mocal setup so I can still run this weekend.
