My 84 4runner I've been fixing up and using as a daily driver broke down on me Tuesday. I've been having assorted overheating issues. I replaced the thermostat last Wednesday as well as replacing all the heater hoses.

Truck drove fine until Friday morning it was spewing coolant when I got to work. Found out the soft hose under the intake manifold had ruptured and emptied all the coolant. Got a ride home and I replaced that Monday and drove it home from work. All seemed well until Tuesday I started to work and I could smell coolant. Pulled over and it was overheating. I'm guessing maybe the block was frozen. Not sure how because I'd been adding antifreeze not water every time I worked on it.

So now it's puffing white smoke out the exhaust like a steam engine ,soooo I think I blew a head gasket or worse maybe. My question is what's the right way to fix this. Just throw a new head gasket on? Have the head checked? Buy a new head? Rebuilt the entire engine?
 
Take the head to a machine shop and get them to check it and true it up. Bottom end should be fine. Since you have it opened up, go ahead and do a water pump and timing chain if it hasn’t been done recently.

Don’t forget about that PITA bolt under the throttle body for the intake to head.
 
yep, have the head checked, they don't like over heating, will crack between valve seats. its fixable, just hope the folks doing it know how to do it properly so the seat doesn't fall out 10k down the road (yes, i've had this happen) Honestly, new heads are available for reasonable cost now days
example, no experience with seller....https://www.amazon.com/Toyota-Cylinder-Complete-Valves-Camshaft/dp/B00V3RZFMW
 
FWIW, i have a good core motor that was running when pulled, had light knock in bottom end, has good head, been sitting for 10years $100
 
seems like bunch of 4 runner guise in this thread. Figured i would join. Sgt is right just do it all right the first time. Replace all the hoses and shit too.
 
Idk yet. Going to try to pull it this week and check it out. Just thought if I could get a new head for not much more than the cost to have the old one checked and fixed I would.
