If the head still has plugged passages bad things can happen ie a cracked head because of a hot spot. I'm sure others will chime in on the best course of action. I'm thinking the best thing to do would be to take the head off and rod out the passages with a coat hanger or some other piece of wire especially since it has evidence of having head gasket issues. It'd be the two birds with one stone approach. I'd do the same with the block and replace the freeze plugs. The other option would be to take the valve cover off and look at it with an IR camera or thermometer and if it seems ok just flush and drive. I'd install a particulate filter somewhere though.

Well I have been letting it run with the flush and I must have cleared out the old stop leak because I now have a leak behind the exhaust manifold and too close to see where its coming from. I hope it is the small core plug and not the head gasket but I will find out.

Replacing a head gasket on one of these old cars ain't that bad if your a little mechanical. Just keep everything organized all lifters valves springs etc need to go back in the same place they came out of. Use the correct torque pattern and use a torque wrench. Have the head resurfaced and check the block for flatness. Might as well have the valves and seats ground if your in there and clean out all the carbon in the combustion chamber. Most use an old egg carton to keep everything organized. If you don't have the tsm get a copy.

Why all this just to remove a head?

If you have the head resurfaced doesn't it need to be stripped down?

You live and learn! I did my valves when I pulled my head off so I guess I had to tear it all apart.

Unless it is a relatively new engine, low miles, and few years on it, any engine 30, 40+ years old, it's silly to not tear it all down and do the whole job. It's just not that much work. If the oil is changed regularly and the engine not chronically overheated, most of the wear in the engine will be in the head.
Here in expensive Los Angeles a cylinder head swap is under $300, for comparison, and that's from a top-notch cyl head only place. I'm skeptical to begin with; not cynical, skeptical: why a 232 needs a new headgasket in the first place.It's unusual. |
