So every now and then I'll clean my engine bay. After track events, where the car is obviously pushed hard, I'll notice some coolant sprayed over my oil catch can and UICP. The picture below shows where I have it mounted. Do you guys think coolant is leaking from the end of the main hose going to the radiator? How do I stop this? And is this a sign of anything more serious?

 

It would be a very good source from it to come from... check it out, perhaps a leaking seal etc?

 

I've looked in that area but cannot tell definitively if that is where it's coming from although common sense tells me it is since its the nearest area that houses coolant :P Any other ideas?

 

Check all of the hoses near there. My hose going to my heater core developed some cracks recently, and it would only spray if I spent a lot of time hanging at high RPM:

 

Good advice here. First place I would look is the upper radiator hose. It could have some small cracks that might not be easily identifiable.

Good luck

 

Thanks I'll check it out

 

Let us know how it goes.

Good luck.

 

well its on the the other side of the engine bay but a couple months after i got my evo, after i would run it hard with around 24 psi i would see coolant spots all in the engine bay. it was from a blown head gasket and the boost was pushing the coolant out the motor through the coolant holes in the block, out the radiator, through the coolant reservoir.
i was clueless what was going on till i popped the hood right after racing and seen it all over the passenger fender.
hope this helps.
