Broke down and pulled the cylinder heads and found bent valves on the side the chain broke on. When a timing chain breaks its a mess so if anybody says thrown a chain on it and keep going dont do it. I even did a compression test which came back good. It actually bent the stem so oddly enough the valve still sealed but I believe when the engine warmed up and the metal started expanding is when the valves started to hang causing all the issues. Now I get to find a solution to the problem of either finding new heads or rebuilding mine. Most likely rebuild mine

Curious, if you ended up rebuilding your head or finding a used one somewhere, I’m in the same situation right now except I haven’t put it back together because I scoped the valves already and I’m at the point where I need to decide. Is it the engine that needs to be replaced can I get away with just fixing the head Gosh, I sure like the car but this is getting expensive quickly. The dealership said to replace the motor and that they do it for $35,000 no thanks

Thats the price given when they don’t want to do the job.
Consider their perspective, who knows what this owner has done to the vehicle and what will it take to correct it.
Incidentally, Land Rover does sell refurbished engines.

Totally fair and I agree. I’m in the middle of my repairs and have found it was the drivers side tensioner that looks to have failed, head is fairly jacked up and the exhaust camshaft was snapped in two just after the first lobe. I bought a used head with cams from eBay and figured I’d give this a try on my own… can’t get any worse since the truck doesn’t run now.

I rebuilt mine, local machine shop did the work. It's pretty straightforward for a competent machine shop. Pretty strong chance valves are bent on your old head anyway. If I were you I would still pull the valves and make sure they are not bent....used parts are difficult and people will tell you anything when they need money just ignorant. My valves were bent under the cams before it went into the valve guides and that slight bend caused misfires under load. Not at cruise, only under load. Not easy to find and a lesson was learned. I rebuilt my engine completely because I was picking up signs it overheated plus my daughter will be driving it to school next year so went the safe route. Look at the cylinder walls when you pull the head and as long as it doesn't burn oil or make noise I'd drive it. Worst case pull the engine and rebuild. I Had a couple grand in parts, machine shop was about the same cost. Not a huge deal and def not 30k. I'd throw new motor mounts in as well, cheap and you're there already. Check your steering shaft bearing etc.. best to handle all that now!! Def download a manual, the timing is something you will need to get right. I have the tools to align everything I can let you use if needed, do a deposit so I make sure they come back. Its a project but nothing that cant be done. Sad these shops wont even make rebuilding an option anymore. Glad to help where I can! PM me anytime.

Thanks for the note and vote of confidence sut123, much appreciated. Have some more parts on order and once here I will be getting after it. Super cool offer to borrow some tools for this but I've already purchased a tool kit for the timing chain replacement and it's currently in the truck, cam locks on passenger side, crankshaft position sensor pulled out and put the lock in there as well as pulled the started and put the other lock in the flywheel. Got the crankshaft pulley off ok, yes 3 foot breaker bar was necessary with that custom deal bolted to the pulley then supported from the underneath by a floor jack while I broke it loose. From there I was able to pull all the timing guides, chains and tensioners out, got a kit with all new stuff to put back in once I get the drivers side head figured out. Appreciate the tips on other items as well. Fingers crossed I'll get it running soon - this isn't a typical wrench for me but I figured what's the worst that can happen since it's already not running so I'm not breaking it any worse .

Of course man, its my pleasure. I dont know your skill level but no doubt you will be fine if you take your time and follow the manual. Dont be afraid to post up as folks on here and myself are happy to help. One more thing to keep in mind. When your putting the head back on make sure the exhaust manifold gasket does not get folded up between the cylinder head and block. The exhaust manifold will go on with the head and the lip of the gasket can fold under the head. Best of luck and keep us posted!
