I made some progress on the HG job tonight. I was able to one of the heads removed tonight but my wobble attachment is starting to jump and I don't have a impact rated 1/2 drive extension so the other will be on until I find something. The gaskets appeared to be in ok shape and hadn't failed yet. After seeing another post I'm a little concerned about leaving the engine apart with my slow pace, is that something to be worried about?

 

if you are worried, spray exposed metal with WD40

 

FYI, rating of extension doesn't really mater unless using an impact driver to disassemble which is not recommended if memory serves me.
......

 

I would cover any open holes or connections with tape (fuel line, oil cooler, etc)

Also wrap a plastic bag on top of the engine so no foreign material gets into the valley.

My engine has been out for months. Other than the torque converter being exposed to the PNW weather... I'm not too worried

 

Yea you are right, and I'm not using an impact driver, but I cracked a socket on the 2nd HG bolt. I've had some terrible luck snapping or cracking sockets on this truck. So I swapped to an impact socket and haven't had issues but this #2 bolt on the driver side HG is in a strange position and I think I've stretched out the impact u-joint I was using. It keeps wanting to jump off the bolt. I didn't realize the force it would take to get these off, I'm starting to wonder how I'll torque them back to spec. I'll cross that bridge when I get there though.

 

Instead of U joint use wobble extensions, just enough play but still stable.

I give both of my summer cars a good dose of WD40 in the engine compartment, before going into storage. Everything metal gets a good supply.


And as mentioned, get those fuel lines ends covered up.

I'm in the process of buying yet another project D2. This time an 04 with 84k on it. Coolant isn't mixing with the oil or vise versa, and it runs cool. It just has a loud exhaust hiss at idle. Pretty sure the passenger side head gasket is leaking at one of the cylinders. Would be awesome if it was just a cracked exhaust manifold, but I'll have to trouble shoot it more once I get it.

Owner had the head gaskets, front timing cover, and coolant system (with a LR grey thermostat) fixed not to long ago at a local LR shop.

Runs great minus the exhaust/head gasket leak on a cylinder. No famous 4.6L ticking.

Mainly buying it for the lift, rocker guards, tires, HD Steering, HD driveshafts, and 04 goodies. It's painted OD green and would be a great trail D2.

I may end up tearing the motor down and doing the head gasket, but it's the best running 4.6L I've come across lately. All the rest are just destroyed from over-heating.

 

Im getting to that part right now with my project. While I guess fresh in your memory, how hard was it to remove all those head bolts? Im getting there, almost, but cant remove those head bolt with the 16mm. Been trying half day already but it wont move a bit. Im even afraid if theres a tool that can reach the bolt near the firewall. Any advice?

 

Weird, I don't remember having even the slightest trouble with head bolts. All easily doable with an impact socket, 24" breaker bar, and 3-6" regular extensions for a couple bolts. No u-joints or anything special. Do you have the exhaust manifolds off?

24" breaker bar is key... I tried using an 18"... 24 makes it a lot smoother.
