Extra fun day, version: Oil pump failure
I was recently looking into offering blueprinted oil pumps for built engines, but got a tepid response. I may still do it for my car, with the possibility of offering the service on a part-by-part basis. We would only use new oil pumps as cores.
If anyone is interested, PM me. I have no idea on cost. To give you an idea of what might be done, see this article here: http://www.motoiq.com/magazine_artic...eprinting.aspx

-- That would be awesome. No one offers such a product/ service currently, AFAIK.. I must have missed that one. Please do

My vote is for timing belt too tight.
Only time i have seen this before is after someone replaced/adjusted the ecentric belt tensioner after a belt or engine modification.
I personally havent heard of 1 taking place on a oem set ecentric.

Its big rpm and sucking the pan dry. The evos have a much nicer oil pump pickup than the 6 bolts do and eat oil pumps less. The kiggly HLA helps keep oil in the pan as well. The only way to fix the problem is to eliminate it. Like Marcos dry sump setup.
Log oil pressure on a big power car doing pulls or launching on slicks.
I ran Daves baffled oil pan in mine for some extra insurance as well.

Yeah I wouldn't necessarily say that the evo oil pick up is better. For one the lazy engineers kept the pick up at the front of the engine.
In regards to the OP seizing the pump, the only things that are going to do that is :
1) sucking in air causing film strength loss
2)side clearance of the spur gear to casing
3)Over hang load on the end of the shaft, as I was saying in my previous post, there is 40 odd pounds of equivalent weight hanging off the shaft for the given rpm point.

An overtightened timing belt is hard to achieve unless you REALLY mess up installing the eccentric pulley. The hydraulic tensioner only allows so much tension to be put on the belt. That being said, the 1st place I would look would be the stubby shaft. Some argue that not having the liner support of the balance shaft puts side load on the pump gears and bearings.ESPECIALLY IN high HP applications. Thats why a lot of folks prefer to run a full length, machined front shaft.
As-far-as damage, you won't really know until you tear the motor down or at least pull oil-pan and cooler. I would pay very close attention to the oil pick-up and what comes out of the cooler and filter housing.
It sounds like you caught before anything crazy expensive happened. You may get away with a new front cover and a good clean out.

To be honest, I think the previous owner put 10w30 in the motor. I thought he meant 20-50 since that's basically what anyone who is anyone runs... Maybe I was wrong though.
I figure the pump failed from doing a 9000rpm pull, with too light of an oil.
The timing belt was nicely installed, STM did it. They do these daily so I'm sure they have it down by now lol.
Maybe I'll look into a baffled oil pan.

I would still drop the pan and check all the bearings for debris on the crank.
My buddy had one let go and started knocking.
Mains were toast, but at least there wasnt much damage if any to the crank. Got all the bearing material out of the pan.
Changed the pump and all bearings, washed it all out.
Good luck to you.

I really should have pulled the pan off the bottom but I decided to pull the engine anyway (regretting it.... lol!)
Well, finally got the motor apart. What a fiasco... I put the engine on the stand without taking the rear main seal off, which took forever to get off...
Let me know your thoughts on what you see below...




rods:




crankshaft




Worse main





What are your thoughts on these rod caps? I can't tell if the bearing was spun or not...
