Never had a cracked head before and am wondering if they can be repaired, or if they need replaced. If repairing them is only a bandage, then let me know because I'm not pissing around with scabbing something together. I plan to keep this truck as long as it runs (as far as I know).
'94 K1500 Suburban 350/4L60E 120,000 miles.
It's either a blown head gasket or cracked head on the driver side causing the wide temperature fluctuations. Passenger side stays normal with the gauge in that side, instead.
Thanks, Snowman
