Semi-Big Problem

[Quick Red Head]

Hi all, I have a semi-big problem that I don't know how to fix because I am not familiar with the inside workings of the engine head. Posted is a picture of the top of the head. The RED and BLUE circles represent the holes where plugs go. Does anyone know what goes in the RED holes and what goes in the BLUE holes (where they lead to)? The ones in RED seem to have oil in them, is this right? And I ask this because I just finished putting the head on my car, and now there is coolant in the passage way above the spark plugs, where all of these plugs go. Please tell me everything you know that can help me. Thank you.

The red circles whould be filled by the same type of allen bolts like the blue circles. They hold down the spark plug valley cover aka Valve Cover 3 (I think). So you should have 4 more bolts with the allen wrench end in it with a valley cover. I'm not sure about your coolant problem. I'd put that stuff on and see what happens.

Red is oil, blue is coolant. Usually the blue plugs don't leak and it's usually the coolant hose at the back of the head. If they leak, it sucks to fix as they're usually seized in there.

I have the red plugs in, well they are out now because of trying to find whats leaking. Poodles, when you say the hose at the back, do you mean just the hose, or the thing that it plugs into that screws into the head? I guess I will check both the 3 plugs that have coolant under them and that hose on the back to see if they are loose at all.

If that hose splits at the fitting it will fill the spark plug wells. Even if those plugs are tight they can still leak (especially if your head was "straightened" by a machine shop as I've found out).
