Hello,
A friend just purchased Bob Anderson's ESP camaro. It's a 1994 Z28. Bob had a shop rebuild the motor and had a high volume oil pump installed. Now there is a momentary drop in oil pressure when you are on the breaks very hard (racing hard). The Lt1 still has the factory oil pan. The oil pressure problem needs to be fixed before it goes back racing.


My current thought is that since we need to drop the K member to get at the pump or the pan, we might as well just put in a racing pan and reset the height of the oil pump. It looks like the Moroso pan and pick up tube are the way to go. Here is the pan: http://spideraccessories.stores.yahoo.net/moroso20185.html

What do you guys think?

Are their any tricks to dropping the K member? It looks fairly straight forward.

Thanks,
Chris Shay

Yes, get the high pressure spring and that will help with your issues somewhat.... you most likely have some lose bearing clearances by now in the motor as well.

A crank scraper should look something like this when it is all said and done....

Lots of work to do them properly and it also helps to cut the counterweights concentric as well to make the scraper more usefull and lower the inertia of the crankshaft.

Unless Bob beat the living dog crap out of that engine the bearings should be fine. It was rebuilt not that long ago (a handfull of years now, but still how many miles could it have)
