Hey guys, thanks for all your help and info, but I took heads down and it was no coolant in cylinders, the only thing that I guess is a problem is that something is missing on my camshaft - it's been touching a trust plate from inside and when engine gets to normal working temperature metal got "swolen" and those two are stuck. When engine cools down it can turn on again. So guys if anybody knows the order of parts on camshaft or if there is something between trust plate and cam?????
It didn't overheated. I turned it off at normal working temperature and after few minutes when I tried to turn it on again it didn't want to turn over like something is blocked. After I tear it down there is no signs that camshaft is damaged. Could it be some ring or spacer missing on cam or any other idea?
I have put new lifters and camshaft in my cougar 3.8 Fi and I crank it but after a while when it exceed right working temperature I've turn it off. When I tried to turn it on again I couldn't. I've tear down engine again to check if everything is on its place and put it up again and same thing happened. Please please give me some advice, I'll appreciate it so much!
