Head gasket on going problems

2001 town & country. Head gasket seemed to be blown. Did the steal seal and it started and was running 100% better then it was before. Then became hard to start and finally wont start at all. Think coolant got into cylinders while useing the steal seal. Is there a way to get the coolant out without taking everything apart. Also coolant reservoir keeps popping open and there seems to be a lot of presure build up. When trying to start is it almost sound like its not getting gas and some popping in the engine. Pulled one plug and it looked like it has some coolant on it. Cleaned the three on the front of the engine and it started easier. I am not a machanic just trying to do a cheap fix to get it running and starting so it will last another year of short distance driving. Any ideas????
Thanks.

TRADRTHOM, you can get the coolant by taking out the plugs and turning the engine over, this will blow out the coolant sounds to me like compression is leaking into the cooling system causing excessive pressure. Possibly a teardown and fix is the only way to make it last. I hope it's just a head gasket not a crack. Did it overheat at anytime? Your luck sounds about like mine.

Yeah, the thermastic went out and I over heated without even knowing until it shut down on the freeway. Replaced the radiator and thermastic but the damage was done. I think the steal seal worked a little cause once i get it going it run farely ok. Its getting it started that the issue now. Like I said pulled the front three plugs and one looked like it had coolant on it. Getting to the other three is a pain in the ass. Yeah its been pretty bad for the last couple years, no job for two years and now too old to get hired. Anyway, thanks for getting to me on this, I'll try pulling the plugs again and turning it over to see if that helps. Just talked to a guy who said he could do the heads for $850. complete, but I m not sure that will fix the problem. Thanks again

TRADRTHOM, no problem, and I know how it is job wise. I got hurt on the job, had three back surgeries and one neck surgery and nobody will hire me so we are in the same boat. Best of luck and hang in there.
