Coolant Draining into Spark Plug Gulley
 

I have a 86.5 7MGE with minimum mods. It just happened recently but I have changed out my hoses about two months ago cause a few were cracked and just today I noticed that I have coolant in the back gathering near my #5 and 6 plug wells. I seen coolant leaking out of the inch size hoses I replaced on top of the valve covers that has an h pipe going to the throttle body and was wanting to know if anyone else has had this problem. This is the first time I have came across any problems with my Supra that I couldn't figure out for myself. Any advice is appreciated thanks :D

Not sure on an N/A, but are there small coolant bypass lines going to your TB like there are on a turbo model? And check your heater lines which run from the back of the engine to your firewall.

I blew that same line on my supra. You'll need to replace it. After u replace it, pull ALL wires of ur spark plug wires. There will probably be coolant in all 6 of the holes, it looked like it was only in the #2 and 3 on mine, but they were all full. Next, take a shop vac and suck the water out. Then put thw wires back in, top off the coolant, and start it up. Make sure to check for leaks after u start the car back up.

Ok thanks I found a small pin hole spraying out from the hose going over the back side of the engine will be replacing it ASAP.
