Went to another autox Sunday and the car did really well on the new ls fbody brake setup.

But I did notice with the hood popped it looked like there has been fluid spray from the cap. When I went to remove the cap to check it the top came off like a disc. I didn't realize it wasn't all one piece.

I was going to just glue it back on but noticed there is a little thing that looks like a vent valve in the center under that disc. Is that what it is?

I might have had the reservoir overfilled slightly, if not I'm thinking it might want a fluid cooler.

I'm using Corvette accessories if that changes anything.

I'm running a cooler (pulled from a boneyard F250), with Corvette accessories and a Turn One PS pump. Even before the cooler got put in, I don't recall having the the cap blow-by issue. FWIW, The Turn One pump has reduced pressure, which I *think* will fix your problem (Less pressure = less heat, less power to run, etc). Maybe you can monkey with the spring and check valve in your pump to do the same thing.

I originally got the pump because the stock Corvette unit made my steering feel way too light.

Weird. I have an extra cap I guess I will replace it for now and maybe see about a small cooler on the low pressure side.

My steering feel is perfect, closer to being on the heavy side with the 275s up front. I'm using a Jeep Grand Cherokee steering box which is contributing to that. It's a tighter ratio and heavier feel than the stock Chevelle box.

I need to inspect the broken cap closer and see if it's really a vent of some sort or if it just looks that way. I found the problem in between autox runs so I was more concerned with finding a replacement to use for the race.

Factory pumps work too hard, and they all have vented caps. They will always puke fluid when the car is pushed. A cooler helps, but some will always seep past the vented cap. I use a large cooler, turn one pump, and take a wrist sized sweatband and zip tie it around the cap. No more mess.

That's a good idea as well, thanks for the tip!

Common problem here. I haven't upgraded to the Turn One pump but I probably will once the stock pump finally gives up the ghost.

In the meantime, I took a hair "scrunchie" from my wife -- fits perfectly around the cap once doubled over and it absorbs the fluid that pushes through. I also keep an extra cap in my track bag just in case mine needs to be replaced.

This is what I do. I run Redline Fluid, B@M cooler, stock steering components on my LT1 and wrap a rag under the cap and zip tie the cap down running the zip ties under the reservoir. Greatly reduced the mess.

My F-body and now my Vette Puke PS with 315's in front. Turn One resolved it on the Fbody and I will be getting one for my Vette soon.

I only do a few autox events per year and it never happens on the street. Not a huge deal was just making sure it was relatively normal.
