Keeping a C4 LT1 alive....

[njansenv]

I'm putting a C4 back together which I purchased from another forum member: the car has an unfortunate history of spun rod bearings....
I paid a local to rebuild the current motor (spun one rod bearing with VERY low miles on it), and would like to ensure this never happens again....

I intend to use the car as a weekend/semi-daily (no problem there) and as an occasional auto-xer on fresh RA1's. Is there anything I should do to ensure the motor holds together?

I "believe" the car should be just fine auto-xing, and may have suffered oil starvation in high rpm sweepers during it's (extensive) track use, but don't really have any facts to back that theory up. Is this a C4 issue?

Details: stock motor and oil pan, stock suspension with revalved Bilsteins, R-compounds.

Thanks!

A custom baffled oil pan would certainly help. Another great alternative is to install an Accusump system. Pretty painless to install if you are used to working on cars and very effective. Plus you get to prelube the engine before start up. We use them in all our race cars.

I installed an oil accumulator and cooler on my C5 for improved reliability and an added measure of insurance in the event of an oil starvation during hard cornering or braking. It is great to have instant oil pressure on start up and with the cooler much lower oil temps.
Curious about the history you mention of spun rod bearings on your LT1, is it always the same cylinder(s) or random? Same block, rod(s) and crank reused or new?

Different blocks and cranks....and rods.
I cross-posted at GRM, and it sounds like it's more likely an unfortunate string of bad luck than it is a C4 oiling issue...which is what I wanted to verify. I'll look into the accusump and pan though.

Thanks all!
