Blew a head gasket, rebuild engine advise please

[rickl750]

Hi Guys,

It appears I blew a head gasket. After my engine warms up it starts smoking (white smoke) I've had to refill my coolant a couple of times in the past couple of days. Anyway, since I now have to take the engine apart I was wondering if while I'm replacing the head gasket it's worth replacing the rings, crank bearings, etc (minus the main bearing since it would require more disassembly) and do a partial rebuild for lack of a better word. I would like to do an engine swap in a couple of years and just looking to do give new life to this tired engine. Any suggestions and opinions would be welcome.

Thanks,

Rick

Unless the motor is real high mileage, and if your just looking for a couple years, I wouldn't bother rebuilding the bottom end. JMO

If you have the money, do it. You'll eventually have to in the longrun.

180 K on the l6 engine isn't that much. Depends what you want to do with it. Twere me I'd look at the valves while the head is off and see if any are burned. I'd replace the valve seals. If she were running good before the gasket failed that would be all I'd do and in the meantime look for another engine. Rebuild that at your leisure and then you are ready for sswap when you feel up to it.
