That's an awful lot of your car sitting on the bench!

Very true! I've got a big bench but it still wasn't big enough. Hopefully it will be empty by the end of the week.

It's been a busy day!
I took a large portion of the KV6 apart to replace the L/H cylinder head in an effort to get rid of a persistent tappety noise.
Swapping the head complete is a bit of overkill but the new head was very cheap. Pulling the engine apart I found some other possible
causes of the noise including play in the cam belt idler pulley, a deteriorated exhaust gasket, and most concerning, too much slack in the
cam belt. All of these will be fixed so hopefully the noise will be a thing of the past.
Your brave.
Good luck with it.

I'm making progress with my KV6 project.
The new head is on, new water pump, timing belt idler pulley, exhaust manifold is back on,
Timing gears and rear belt are on.
The goal tomorrow is to finish the belts and carry on with putting the pile of parts on the bench back onto the engine.
One interesting find was a pile of cooling system poo in a backwater behind a blanking plug on the old head-Yecch!

My post above won't take pictures for some reason so here they are.
New head on
And here is the poo-like deposit in the old head.

Well, Today's goal was to finish installing the timing belts on my KV6.
Unfortunately the old bucket of bolts bit me on the ass today, or more accurately the idiot that had the engine apart last did.
When you set the timing on a KV6 you loosen off the front timing pulleys to allow some adjustment. When I did that I found the pulley had too much movement.
I removed the pulley and found a big chunk of the camshaft flange had been broken off. The piece wasn't in there so whoever did it just bolted the thing back together and
hoped for the best. Hmmmph! The exhaust cam was in the same condition but that didn't affect me as there is no pulley on that cam. At least it didn't affect me until I tried to remove
the rear pulley on the cam. It seems Mr. Muscle had cranked the rear pulley on to make up for breaking the other end of the cam, and with the other end missing it isn't possible to remove the pulley.
Broken Cams
So, the plan is to remove the head, drill the bolt out that secures the rear exhaust cam pulley and swap the two good cams over from my old L/H head. Easy-Nope!
Seems instead of using anaerobic sealant on the cam carrier the last guy used RTV adhesive sealant instead. It is stuck on good!. I resorted to using a jack under the broken exhaust cam to pop the outboard front corner of the cam carrier off but it is stuck so fast the rest won't budge. Tomorrow I am going to try using the floor jack with a length of pipe under the intake cam to get the carrier off, hopefully without damaging it.
Anyway, if you have read all of this, Thanks for listening. And wish me luck!

At least you have a couple of spare cams you can use where the "spanner monkey" has been.
Good luck with the job, and all with the engine in situ too. I tend to remove engines if major surgery is needed, as my back doesn't take kindly to bending over engine bay's these days.

Jeepers Rich - but at least you're finding and correcting all the previous bodgery!
Good luck with the rebuild: it never ceases to amaze me how small jobs rapidly escalate into something much larger once you've started and found some monkey has been there before and bodged things. And you ask yourself "Why???!"

Good luck Rich, keep us updated.
After I've asked myself Why???! My next thought is often "how much will he scream when I kick him so hard in the nuts he has lumps in his throat"!!

It's coming together! Today went much better, cams changed, front belt on and reassembly has started.
After a bit of persuasion the cam carrier popped off, and I was able to winkle an impact gun through the mass of hoses and wiring to get the rearmost pulley off.
Unfortunately I had to pay local prices for the replacement rear belts but the parts guy owns an Aprillia. We had a good chat about hunting out parts for specialty vehicles and he gave me an extra $20.00 discount.
Back at it tomorrow.
Nodge, My back is holding up OK but my hamstrings and knees are killing me as I have been standing on a milk crate and leaning forward for the last 3 days to get access to the engine bay.
I had a moment a couple of days ago when the crate kicked out from under me when I was putting on the head. I got a big bruise on my arm when I landed on the closing panel but I didn't drop the head!

Nearing the end now....all belts on, A/C compressor on, R/H engine mounts are back together (Like building the bloody Eiffel tower!) and the jack is out from underneath.
It may be finished this afternoon if I push through, or if I am sensible, tomorrow.
Just out of curiosity (And so I can justify to my better half spending a week's vacation on this) does anyone know the Land Rover book time on a similar job?
I would think a head gasket change would be close.
One last pic for today. Everything is back together, less the engine cover. Oil is in, coolant is in but I have had enough for today. Tomorrow I will start it so it will either be cheers or tears. Assuming it is cheers it will just be a matter of bleeding the cooling system and taking it for a test drive.
