I had some coolant in the spark plug valley which I think fouled out my plugs because my car wouldnt start. Where did it come from. It was just coolant, no oil mixed with it. Didnt seem to come from the valve covers.
where coolant is comin from?

No, not that hose. I checked it out and it was fine. Is there somewhere else it could of came from?
If you removed the intake recently you probably spilled some down there...if not then your coolant plugs "big fucking Allen head plugs" are leaking..
Are those the ones between the plugs? How can I keep them from leaking? Sorry if that sounded like a stupid question.
take them off...clean and reseal it.
they are a pain in the ass to take off...at least from my experience so make sure you have a long long breaker bar.
another thing you could do before going through the trouble of that just to make sure is when the engine is at operating temperature...you can do a coolant pressure test and observe for leakage.

those 4 plugs go to oil, not coolant.
only coolant plug i know of is on the side of the block or freeze plugs.

I would take a look at the coolant lines that route from the hard line around the block to the TB, to the ISCV

Grim is correct concerning the spark plug valley plugs...they seal off oil, not coolant.

they have some tubing thats about 5/8 in thinck that goes up to the tb and thats where i would check first i was leaking out of there on the bottom for my 90 n/a i don't know it it helps you but i would check there.
