I heard a small, bubbling coolant leak around my intake plenum. I could see some coolant pooling in small amounts on the bottome intake plenum right below the fuel rail mostly in the middle. I could not see from where, only hear. Important: I no longer have a coolant line running to my ISC and my throttle body. Are there any other hoses around there? Any others on that side at all? If not, can someone plz list the possibilities? Thank you very much. I've got it still torn down from the knock sensor replacement I did this morning. I really need to do this today, tomorrow latest for work of course on Mon. Any help would be Greatly appreciated.

coolant pressure tester. pump it up and look for the leak.. if dont have any mechanic friends who own one you can prob rent one from autozone or somewhere of the sort. or just buy one..
