    Pitted head on my Rolls.

    I have had issues with loss of water and fine bubbles in the radiator. Assuming it was a head gasket I bought a new gasket and got started on disassembly today. Attached is a shot of the gasket with a clear gap between the combustion chamber and the water channel on the top right. Also a shot of the head with minor pitting.

    I'm trying to keep this cheap as I'm putting a 4age motor in eventually and only need this motor running until I find time to fix my Series Landrovers tcase. So I don't really wanna get work done to the head professionally. I'm wondering is there a way to patch the pitting by means of solder or weld.

    To fill the pit you need to go back to bare metal. It may be too late to do a cheapie repair as cleaning the pit will be deeper than it looks. Solder is useless, it will melt quite quickly.

    Some time ago I rescued a slightly corroded Mercedes 250 head by tapping a small screw into a pitted area after countersinking the thread hole, then shaving the screw head until it tightened up flush with the face. AFAIK the engine is still going 5 years later.

    In any case a head face may rescue the surface if you are lucky.

    An old Jag trick to overcome minor imperfections was to use something like Permatex Copper Spray a Gasket, a high temp sealant.
    Could be worth a try?

    Thanks for your responses. Took it to pro-port who said welding it was possible but would require disassembly and planing afterwards, costing up to $350 just for that. Bit the bullet and bought a head from the wreckers $50. All back together waiting for a mate to bring a torque wrench. No visible pitting on the new one and the engine was complete in the wrecked car so hopefully it was running right when it crashed! Thanks again for your input. Hopefully it'll run tonight

    Eventually it'll have a 5spd and a 4age. I'm also considering locking the rear. But of course most importantly is a paint job and some nice mags

    Got the head torqued and the thing just does not fire. The valves are clearly opening and closing around the spark but it's just not starting. Trying to throw a bit of fuel at a time in the carby but not helping. Noticed that the mixture screw on the head side was snapped off by previous owner but was okay before I took off the head so that's not such a problem. Suggestions?
