Hey Vundba, As others have suggested, it would be best to check the crankshaft side thrust before removing the oil pan to look for any bearing issues. You hadn't mentioned the position of the needle on the temp gauge or your oil pressure - was there any indication of an over temp condition ?
This is NOT a recommendation - but one time a friend had an old Fiat with a similar engine seizure after each hot shut down. He hadn't properly checked his crankshaft bearing clearances during a low budget rebuild. After it stranded him for about the 10th time, his solution was a "Hold My Beer and Watch This" low budget fix for his low budget rebuild ... He held the throttle wide-open after a cold start until the bearings automatically adjusted themselves to allow for the proper oil clearance.....
He drove that Fiat for another two years before selling it to his younger brother.
