Help antifreeze/oil in sparkplug wells

So today I got a 2002 mustang gt knowing it was running rough went change spark plugs and the pas side spark plug wells were filled with a antifreeze/oil mix doing a compression test tomarrow any clue to what it coulld be I'm thinking intake manifold gasket or cracked intake manifold. Head gasket doesn't seem feasible at the moment tell me what you think.

Lol 99% chance of intake mani/ and gasket. Those plastic ones break ALOT! Save the heartache and replace with aftermarket.

If it does happen to be the intake manifold, then you won't regret replacing it with the FRPP replacement manifold. They are far and away a better part than the Dorman.

Thanks for confirming my suspension I drove it 40 miles today while running rough no over heating or anything didn't really fill like a bad cylinder compression yet its not really firing great so hard to tell. Do you think the cops can be cleaned or am I just gonna need a new set a little bit on a budget

The COPS would be fine, if you pulled the COPS as to get to the plugs, you should inspect the rubber boots and springs, if they are cracked, hard or brittle, go ahead and replace the boots and springs as they are sold at any auto parts store on the cheap. They are sold individually, and each new boot comes with a new spring. So it may be wise to replace all 8 while you are doing this job. I replaced all 8 when I bought my newest stang just for a piece of mind and it would suck to have a boot rip and need a ride to the auto parts store since this was my DD.

Well it won't run very good with any fluids in the spark plug wells.
Fix the coolant leak and dry out the wells and then see where you're at as far as any misfires. You might get lucky and this coolant leak is simply a leaking heater hose.

If you post some clear pictures of where you think it may be leaking from, we can possibly be more help in determining the cause of the leak.

So didn't get much done ended up trying to clean everything out couldn't pull sparkplug from cylinder 3 I think but swapped the other 3 ran twice as good but still running a lil rough could be problem with intake gasket? Will end up doing new gaskets anyway and comp test tomarrow.

I did not but it almost looked like fluid leaked down from the seal It was harder to tell after I blew the remaining fluid out I'm getting closer and closer believeing its the gasket. One question though could this coolint get into the heads/piston cylinders?
