Coolant in #4 Plug Hole

[steveb24]

Changed my plugs today, gapped them at .38 (gettin ready for nitrous), but i had a problem with the #4 Plug. As soon as i pulled it there was coolant ALL over the COP and plug itself. I read all the search threads on coolant and plugs, and the closest i got was svttech saying "coolant in the #4 plug well is a common problem", but never explained why. This is ONLY this plug. All the others were dry and good. I fired her up and she runs great, as it did before I changed them. Dont notce much with the .16 gap difference either, but idk if I shouldve anyway. Lil help here as to why theres coolant in there? I can def smell it when i pop the hood and run her..



and feel free to tell me I need a new manifold.. Hello Trickflow

but really, anybody ever have this happen? ive never heard of this on an 02

After you removed the coolant did it return? It could have just been spillage from some previous engine work...

i was thinkin thats possible.. since i did just have some work done, but i havent driven it yet. I just finished changing the trans fluid w/ some rp synchromax, so ill drive it for a few days and check.

could also be a sign of a leaking coolant hose going to the heater core

hmm.. i just wonder why everything "looks dry", but than in a hole covered by a COP, there all the coolant sits. And Randy, where is this hose you speak of? Hopefully thats it, but why would it leak? cracked or not connected properly?

there are 2 hose's at the right rear, comming from the heater core and going to the engine. a clamp could be loose or a hose could be going bad, also on 2001 up the have a plastic "quick disconnect" at the heater core which has o-ring and can also leak

If you have the updated intake manifold, I doubt that's the problem. I would check all of the coolant hoses near the area that is leaking.

 

[steveb24]

well im gonna go check the hoses now, but i really dont know what to look for. a crack in a hose can be really hard to see, esp in that location.

I had one of the heater hoses blow @ 50k miles (one closest to passenger side) and left 2 gallons of coolant in my engine bay, the rear of my car (bumper/trunk lid), and the engine bay. I would def check em before they blow out and make a real mess. Save yourself the trouble and order those 2 hoses from the dealer because all the places that carry them don't have the quick connect adapters crimped on and they are all cut to fit annoying crap

hey thanks for the idea. It turned out to be left over from previous engine work I had done. I pulled the COP a few days ago to find it all dry. So I felt a sigh of relief after that. thanks :SNSign:
