I have an '06 Z06 and the engine blew during a track day. No previous oil problems or any other engine problems. Anyone have any similar experiences? Looking for feedback.

Were u on stock tires? Mods?

Project Opel

No mods. R6 Hoosiers.

seems like most of the engine failures are coming from hpde events.

And many on sticky tires. Although, there have been a few on the factory rubber.

Let me guess - high speed (maybe banked) left-hand turns?

But doesn't a dry-sump eliminate oil starvation issues? I thought positive pressure oil systems weren't affected by centrifigal forces?

Can we get some more details? What do you mean by "engine blew"? Got a box that looks like this:


Or something less catastrophic?

Is the car at the dealer or a shop now?

Project Opel

The engine literally blew up. Two connecting rods blew through the oil pan and were found on the track. The oil had been consistently checked and was up to level, although the car did take 2 and 1/2 quarts of oil between the first and second day on the track.

what track?

Dreamin -

That box looks very familiar.

You burned over 2 quarts of oil and didn't think to stop ???....

Project Opel

Hindsight is 20/20. You can be sure it won't happen again. That's why I posted here to make others aware of the potential problem.

I can burn ~1 quart per track day (1/4 qt per 20-30 minute session)... is that not normal ?

(Not sure if OP means 2.5 quarts over 2 days, or 2.5 quarts in one day)

dvandentop

what track?

Project Opel

2.5 quarts over the 2 days -- 250 miles the first day and about 200 miles the second.

Dreamin

That sounds like a normal amount of oil to consume over that many track miles.

Did you check and refill oil after every session?

Depends on the driving style and to some extent the partcular car. My car burned very little oil at the track for the first 3 years, then a little bit more - but I'm not doing lap after lap at an almost constant 6500+ rpm. I tend to keep the car in a higher gear when it's going at a constant speed around the bend (like turns 2 and 8 at Big Willow). It will also burn a little more on a hot day.

20k track miles on the 06 Z06, doesn't use a drop of oil. I rarely go over 170 though.

Project Opel

The oil was checked after every session. Sessions lasted about 20 to 40 minutes. Not a particularly hot day.
