New HG needed, what else should be replaced?

Coolant is being pushed out of the coolant tank via the cap without the engine running hot (new hoses, t-stat, and water pump installed). I will replace the tank cap, but I'm betting on a blown Head Gasket. I am in the process of ordering a new cap and the HG kit from Atlantic British, anything else I should repalce while the engine is torn down? Like the front engine gasket? I have replaced head gaskets before without having the block skimmed, thoughts on this? Thanks in advance...

I had my heads planed, it's up to you. If the truck has ever overheated , you should definitely have the heads done.

Having been through a head gasket replacement on my D1, I am not sure why everyone just changes headgaskets and puts it back together. Not long after doing my headgaskets, my engine developed low oil pressure due to bad crank bearings.

I suggest pull the block out and check/replace crank bearings. The only thing left in there once the heads are pulled is the block anyways.

Whoa Randall! Don't order the HG kit quite so fast. A friend here in Charlotte had the same thing happening last spring and a new recovery tank cap was all he needed to solve the problem. Just go by the Advance Auto there in Conover and pick up a new cap for $10-$15 or so. Try that before the big order from AB or P.T.

Agreed. Caps fail all the time.

Wow, lemme see, I now have 17 Land Rovers and only one of them does not have what I suspect are the original expansion tank caps.

The ONLY one I've seen fail in ten years is ONE in a Range Rover Classic with the level sensor.

OTOH, I have done at least 100 head jobs...

As for the crank bearings, do not open the journals unless you are prepared to replace the bearings. The workshop manual indicates that if you open the journal the bearings should be replaced.

If the truck has good compression and oil pressure, don't mess with the bottom end, they are damn near bullet-proof.

Whatever, its cheap insurance and an easy place to start.

At the risk of causing some folks to spit coffee/soda/beer all over their keyboard, just because it's cheap doesn't mean it's the right thing to do.

Given the propensity for these vehicles to have the head gaskets fail and the symptoms as described, my money is on a weak cooling system (age of water pump, thermostat, radiator, fan clutch?) leading to failed head gaskets and warped heads.

Replacing the expansion tank cap is likely merely postponing the inevitable and risking further damage to the engine.

It's not like I told him to get a bottle of "head gasket fix". He said coolant was pushing out of the cap. Therefore replacing the cap isn't a completely crazy idea.

I replaced the cap and the coolant is no longer being released via the cap. But coolant is leaking from the rear of the head on the passenger side of the truck. So I'm looking at replacing the head gasket, front cover gasket, and oil pan gasket. I want to rebuild an engine to replace my high mileage lump at a later date so I'm not interested in replacing the cam, lifters, or bearings. Thoughts?

That is the spot mine leaked from, so yes head gaskets are in order. I do however wish I had put in new lifters while it was all apart, I have a ticker that happens right at start-up but goes away after a sec or two. I also had a gunked up engine with a year old filter on it and tar for oil. I should have at least pulled the lifters and gave them a good soak.
