99 Tacoma Prerunner Valve + Coolant = Blown Head Gasket?
So I decided to take a part my air intake plenum and give it a good cleaning... Noticed when I did that there was a good amount of engine oil coating all six intakes as well as around all the valves. There is also a small amount of coolant noticeable around one of the intake valves in the #3 cylinder...
What do you guys think? Blown head gasket? I'm not getting the typical overheating or milkshake oil but I realize that's not always the symptoms of a blown head gasket. I just recently replaced the valve cover gasket on the same side of the engine as cylinder #3 due to a leak.
Any thoughts would be helpful, thanks guys!

Thanks, I've been trying to find some other reason for that coolant to be there (besides the head gasket or a cracked block) but no success.
Anybody else have any good suggestions / experience?

I believe at one point there was a k&n filter (the air box has been patched up with tape).
Also the throttle bottle and the entire intake was coated with oil... Appears to me the heaviest amount came from cylinder #3 and was sucked/blown around from there to all the other cylinders. I might be wrong on that...

The next thing I would recommend is seafoaming the intake via the PCV valve.
once you have done this then you will be able to see if there is really engine oil and coolant or if it was intake filter oil.
There is a coolant line that goes to the IAC on the throttle body that may be able to leak so be sure all of it is sealed correctly and reassemble and seafoam it. look at in a couple of days to be sure...
