Did you ever figure this problem out? After what you’ve been through my mind go to pressure getting in the system as other people have said. Which would be a more internal problem...
No, mate, the car's still acting up; I concur with pressure in the system and I truly thought the O ring replacement would fix the issue, I was pretty disappointed when it didn't. I'm just throwing money at the car at this point, as much as I love the car I think it's time to just move on.
[/QUOTE][/QUOTE]That's a possibility but before this car was parked for a few years it ran fine *as is*, I'd rather not try to reinvent the wheel if I don't have to. I already need to replace the return type fuel system as the hoses are seeping, gas smells freak me out, and do some other stuff so trying to keep cost down.
Track fees, hotel, gas/food, new alternator, new auxiliary water pump, and 4 X Nitto NT01s. Granted, it needed new tires, I was just listing how much the weekend cost me, it's kind of irrelevant and I was just bitching
No, and I don't know how to check.
How do i know if the tank is overfilled, it's a solid tank with no fill marks? Also, is there a way to test the cap is venting properly. There's no instructions
Car has been sat for 2 years or so so leaking O rings would seem like the likely culprit. Hopefully.
Car belonged to a friend of a friend, I know its maintenance schedule, know who did the work and know who tuned the car and the suspension so whilst I agree buying someone else's project is never a good thing I thought I would luck out here. Looks like I might have been wrong
No gauges at all, something I hope to remedy soon. And, again, I don't know how full is too full?
When I changed the cap I drained most of the coolant out and used a flashlight to look inside, it's remarkably clean and corrosion free from what I can see.
Thanks everyone for the comments, gives me something to go on.
Might be time to move on. It depends on what you want. These cars can be good track cars but they require some modifications to work well under extended periods of high-RPM driving. Forced induction produces so much excess heat. I’ll gather some links of what others have done to mitigate this (intercooler flow mods and tank-routed cooling systems are the most effective for track usage). The fact that you can’t reproduce the issue on the street leads me to believe your pressure is coming from heat, not leaking boost. I’d boost was getting into the intercooler system, you’d be able to spray coolant during your testing in Mexico. If it stays dry, then it would seem as though heat soak is causing the system to boil over. Your only solutions to that involve cooling mods. There is at least one member here, @MalcolmV8, who has done extensive cooking mods. There was another member, jimmysidecar (or something like that - I’ll try to find him), who tracked their Cobra for extended periods as well.
. It's just so strange that I can't even get a single hot lap out of the car, I know it's hot here in Houston but come on.I don't believe so, when the pump kicks in you can see the coolant running through the system if I pop the cap of the reservoir off and it's not a gentle stream, it has a fair bit of turbulence to it.
