just picked up this car 2001 carerra 4 3.4 eng
idles ok , found antifreeze in oil, press. tested ok when cold, overheats when idling for a bit and with the press tester conn. builds up high press . run smooth but can smell sweet exhaust and is visible. compression good on all cyl. pressure tested all cyl with plugs removed and not leaks holds press.
small drops of antifreeze visable on exhaust ports of cyl. #1and cyl. #4
if this is a head gasket issue can it leak over to booth cyl 1 & 4

i am aware of the listed oil cooler issues but that would put oil into the anti
thanks in advance for all replies
