Head gasket

[IneedAmotor]

What is the procedure to change the head gasket? Also, i snapped a head bolt (just above the deck). Would an "easy out" be the best idea or would that make things worse?

Well obviously remove the head. Put new HG on and torque to specs stepping up from 20 ft lbs all the way to spec. As far as easy out, some people have used it with success, try doing that. if it doesnt work take it to a machine shop who will help you.

Using a good penetrant and time will greatly help getting that broken bolt out.

 

Heat almost always works but localized heat around the bolt hole on the deck may cause it to not be level in that area or even compromise the shape of the bore if it's near the bore.

Thanks for the advice! also how will i know if the head or deck need to be skimmed at all? are there any signs to look for?

If you snapped just the headbolt head off, once you pull the head off, the shaft should still remain, a good set of vice grips should break it loose, unless it's the one in the middle where it rusts quite often. If that one snaps, you may need someone to come and weld on a bar or nut to the shaft so you can break it loose.

 

If their is excessive pitting you should consider a slight skim or resurface.

 

Good luck sir, remember to use the correct shape chain tensioner and loosen the cam pulley before you go around removing the head. I found that using a large pipe wrench, sitting on top of the head bolt kept the cam from spinning to free the pulley.

 

edit: by pulley I mean gear.
