I pulled my plugs today and it looks as if coolant has been leaking into my housings. The rear rotor looks fine but the front looks bad. Is it posssible that the coolant might get in through the intake? I am asking beacuse I thought that if a seal was broken it would super preasurize my coolant and dump it all out at one. Lately coolant has been disapearing, but there are no visable leaks and the coolant resavour is always full or over flowing. Could it be an intake problem or do I need to rebuild my engine? Thanks.

water seal o-ring failure is common...sounds like what you have...
hard starts..when warm
white smoke at start (more then the normal)

that's rebuild time...please think about upgrading your oring to Hayes silicon while you are at it...approc ~100 bucks from Hayes engineering..But I dont recommend then when it comes to engine building

 

The car isn't hard to start, it starts fine, there is some white smoke on startup. There is good power too. When you drive the car the coolant just goes away, there is NOT any external leaks. The front rotor housing is the one that has the coolant leak. We found the leading plug to be wet when we pulled it out.

Is it possible that the seal went away on the intake side? That would explain why it doesn't go down when the car is sitting?

Is there any other way besides a blown coolant o-ring that would explain coolant it the housings?

 

One thing that happens when you are losing a coolant ring is that when the engine is warm, and it is a coolant seal, some of the pressure actually will pressurize the coolant system, sending more to the overflow tank than it normally would. Sometimes when you check the overflow bottle, you might have specks or small clusters of oily brown residue in it as well as in the thermostat housing. Although again, if you've ever mixed the redline water wetter in with your coolant (depending on which coolant brand it is) it can produce the same gunk. A little confusion if you have used water wetter, but if you haven't then it looks like a seal is going, and will eventually go with a nice billowing white cloud coming from behind the car if your driving it.
