So the v12 has indeed held me up and I wont get the head back today.

Hey man you ever come across that missing piece of plastic?

Won't be the last time a Jag makes someone miserable.

I'm sitting here on sabbatical, trading a little on the forex market, waiting for these guys to finish this jag and get my head done.
Very painfull.
They have had it for a week now.
The killer is arranging for help to get the head back on.
Its not like everyone else is on sabbatical as well......

I'm in "hurry up and wait" mode................

On the way to the head shop right now.
Here we go again, round #2.
I'm going for the rear naked choke this time...

Great! I hope to see this thing up and running by the time I'm there. You have 3 weeks!

Got the head on
And yes its timed right this time.
The valves need to be adjusted.
The motor spins smoothly by hand.

So with the cam in the below position and the OT on the vibration damper set to the peg on the block I locked it in.


But I have one question.
Does the cam spin 1/2 revolution for every one complete turn of the motor?
As you can see in the picture, the sprocket dowel is in the 7:30 position.
I spun the motor 1 complete revolution and found the dowel the in 2:30 position and I almost crapped myself.
Of course I spun it one more revolution and it was back in the 7:30 position.
I know that since the crank and cam sprockets are a different size, rotation wont be 1:1. My educated guess is that the cam sprocket as twice has many teeth.........
If all goes well I hope to breath some life into her tomorrow.

I think your supposed to spin the motor 2 full revolutions, it being a 4stroke and not a 2 stroke, and then make sure the marks line up again.

Then again I am the retarded one that just went thru rebuilding an engine to only have an oil leak that I can't figure out where it is or how to fix it. So take my advice with a shot of JD and it might make sense.

2 complete revs got the dowel back in the right position.

On any 4 stroke engine, the O TDC will come around twice for each power stroke.

First time, it is on the compression stoke, second time it is on the exhaust stroke.

You are learning young grasshopper.

Yes I am Jedi Master.
Thanks..

I'm expecting a phone call today when this damn thing is finally running. I want to hear turbo powaaaaaaaaa!!!!!

The build is officially terminated!
I installed the head, timed it right, I believe, may have been off by a tooth.
Spun the motor by hand at least ten time.... and still managed to break a rocker arm on the #6 cylinder.
I'm done........
Major waste................. And I'd like to say I have no regrets, but I can't.

I will be posting the part out on the "parts for sale" board.
Thanks for all your help.

Sorry to see this. What happened? Even if you decide to scrap the project (and I don't recommend it), it's worth knowing. Get someone over to check it out. Did the bottom end get decked or different rods/pistons get put in? Did the top end get milled?

Something is wrong here.

Rotten fucking luck. I understand your pain, but I urge you to push through it and figure out what got fucked up.

Good luck going forward, either in the rebuild or the sales.

Well, at this point I'm somewhere between depressed and discusted.
I have no idea what went wrong.
I timed it, spun by hand a good ten times, did the valve job, tripple checked them by spinning the motor, and rechecking and spinning the motor again.....
I started the motor and it was making a ton of knocking noise.
It sounded like it was coming from the valves.
I pulled the valve cover back off and inspected the adjustment I had just done.
Everything was fine. The adjustment was good and at this point, the rocker arm was not broken.
With a little research I decided to go back in and check my timing. I was off by one tooth.
So I fixed that and and spun the motor, it got hung up and thats when I look to the rear of the head and saw the broken arm.

One tooth should NOT have been enough to break a rocker. I'm not very familiar with the big six, but I know that much. Something else is going on here. Not sure what, but have yourself a beer, calm down, and let someone who is very familiar with the chain drive beast chime in.

Sorry again, I know it's the worst feeling in the world.

Wish me & the crew were a little closer, we'd come over & try to diagnose things over a 24 pack! I feel your pain. Take a break & then push on. You'll be rewarded once converted to the dark side. <insert darth vader icon here>

I would love to move on but I obviously don't have the skills, and my budget has been busted.
In honesty, I don't think it was all my fault.
I too wish you were closer. I have no one here with the skills I need to get thru this.

I have a spare head on a motor in the back that's been sitting I'll give you for the price of shipping if you wanna try to go 1 out of 3 tries.

The rocker arm may have been damaged during the last episode. I'm planning on replacing all 12 before I out my turbo motor back together. They're not meant to handle that kind of stress. If you were able to spin the motor over by hand it certainly wasn't caused by interference.

x2 I think you'd feel some binding, unless you were cranking it with a breaker bar.

I was using a rachet with the big socket on the crank nut.
How can you turn a motor all bolted in literally by hand...

Pull the spark plugs.

too late

You would feel interference, even with a ratchet. One tooth off shouldn't cause that anyway.

How are you timing the camshaft to the crank? You hopefully know the M30 is a Slant - 6 and vertical (re: Bentley manual, Ch. 4, Fig 4-26, straight up and down) isn't referenced to the car's body. The straight up and down mentioned in the Bentley is the center line of the block which is perpendicular to the deck of the block. If you position the camshaft sprocket bolts referenced to the car body, you're going to bend valves.
