Hello out there - I braved mid 30's weather yesterday to get the head off my '93 8-valve 940 (130K). I was hoping to get the head gasket replaced before it gets really cold - (my Volvos like to torture me by requiring repairs only when it gets nasty outside...never on a sunny day in May). To my horror I find 2 rather substantial potholes eroded into the head, which overlap the gasket sealing rings for 2 cylinders (1 & 4). Anybody out there ever repair something like this? I've got MIG welding equipment and can get some aluminum wire and Argon gas... but I don't know if it will "Stick" to this alloy. Any ideas?
The alternative is a rebuilt / junkyard head - assuming I can get one without having to buy the whole engine... Thanks.
