Reving in neutral
What are the negative effects of reving your C5 in neutral to the redline and back a few times. Will it actually do some serious harm, or is it alright to do once in a while. Say this C5 has a upgraded valvetrain.

It's very hard on the rods. That's why many drag racers go to neutral after the finish line rather than let the motor coast down in gear. High RPMs are harder on a motor with no load. Some motorcycle owners manuals will even give you a max RPM for no load and it's much lower than the redline.

FYI, it's supposed to be hard on rods and whatever, but have you ever heard of anyone blowing up a motor by revving in neutral? Assuming of course that you have a rev limiter.
I haven't.
Having said that, I rev it up whenever I feel like it in neutral. I just don't do it when it's cold.

I saw a motor grenade on the starting line while reving high with no load. Chunks flew everywhere. A piece of a rod even hit the starter on the arm.
It was a manual trans car and he had been hitting the rev limiter while waiting for the light. It let go just before he dumped the clutch.

Well after a little hard spirited driving, the car sat over night, and there was oil all over the floor of the garage. I moved the car to a different spot, put some plastic down, and no more has dripped since. There was about 30-40 drops on the ground.
Is it possible that oil could blow out somewhere if the motor sees to much rpm, and just drip down for a while?

Yeah, I got an oil change that same day. The plug and filter are both tightened well. It doesnt seem to be dripping from that location....kind of seems to be coming from up in the motor area by the underdrive pulley or something.

If you had just gotten an oil change, I bet they spilled it while filling up. The oil slowly dripped down the side of the engine and left drops all over the floor.
I've done it myself.

I took it to my friends work, a quick lube place, but I did all the oil pouring and everything.
I am just hoping no seals blew when I was doing the spirited driving. I will take it to a dealer and see if they can tell where its coming from.

I'm with Dope, it's probably oil that was spilled during the oil change. After almost every oil change I get on any of my vehicles, there seems to be a spot of oil on the garage floor the next morning, then nothing after that. If you put plastic on the floor and didn't see anything, I wouldn't bother bringing it to the dealer for a check. If anything, they'll make up some sort of malady and tell you that you need have your muffler bearing or 710 filler replaced.

A forum member did that once here not long ago. Was revving it hard in neutral for his buddies and, pow! That's all she wrote.
