shouldnt the crank timing belt pulley be held into place by the crank pulley for the belts once everything is assembled and torqued down? Maybe try putting both pulleys on and see how things sit. Dunno, thinking out loud..

Yeah, that's what I thought too. I am gonna put the crank timing gear on, and then the pulley, and see if there is any play. The rear lip of the timing gear is so thin it's almost razor sharp... so it only takes a minuscule amount of movement to make things go bad.

Seems that the factory manual torque setting is too high.

Some aftermarket tensioners don't need the spacer/washer used behind the factory one, any chance it was left in there and was rubbing on the inside of the front cover?

Hmmm.... those AULRO articles mention overtensioning a lot, something I also thought of... it's hard to check the tension after you start to turn the wrench to tighten the bolts... as you tighten the bolts you inevitably raise the tension on the belt.

But, with all the disassembly complete, I will spend tomorrow scrubbing old gaskets and seals off and then start putting it all back together again...

Then run your engine without the cover to see how the belt is doing:

Well, everything was going well today as I put the engine back together. I had cleaned the head and block surfaces real well using some 3M Roloc plastic bristle brushes, put on the head with the new gasket and bolts, everything was looking good.

Then I went to put on the first glow plug. The book said to torque to 20 NM. So, me being anal breaks out the torque wrench. Made it to about 15 NM before I feel it give way.

FUCK MY ROVER-GOD-CURSED LIFE. The glow plug has stripped out the head.



So now here I am, having already used the gasket and bolts to put the head on, and a fucking useless hole in cylinder 4.

So now I am sitting here trying to decide if I buy a new head or try and get aluminum helicoils and fix it that way. Either way I am now looking at having to buy a new gasket and bolts.

Sorry to hear Neill. That's some serious bad luck!

damn. Those bolts can be used up to three times btw. But it's time for a new head. those threads are under compression. regardless, there may be some shavings in the cylinder now from the stripping.

That seriously sucks. The fact that your wife hasn't made you sell the D is a mystery to me, and speaks volumes to her.

If it's ANY consolation, your head and gasket is MUCH MUCH cheaper than mine. To the point of envy.

So now that I have gotten home, had a few excellent San Diego beers, and calmed down...

I am in a thought exercise. I basically have 3 choices:

1) Helicoil the glow plug holes. I might as well do all 4 if I am doing it. But as Mark noted, these threads will be under diesel compression forces. How well do helicoils hold up?

2) Buy a new head in stock configuration. Don't see one in the states, RN, AB/BP, RDS don't show them. Turner Engineering has a stock one for ~500 bucks plus shipping. RDS might have one, but George doesn't put a lot of stuff on line. I already have an e-mail out to him.

3) Since I am already looking at Turner, they have a "high performance" head that's 800 bucks. Don't know that it's worth it, but they have it.

What does the common wisdom say?

When in doubt, buy new. That's my motto. I'm slowly replacing every component with new counterpart.

What's the difference between a stock head and a high performance head?

I'm sure someone this side will chip in. Used 300 tdi heads are relatively common over here.

That's bad.

If I can help...

Here's the Turner page for those that are interested.

Turns out I live just down the road from them.

Get a new head from Turner, take a pic of it, send it to me and I will go to a very good brujo I know close to the Haitian border and for a small fee we will cast some spells on it to break the curse .

Seriously, get a new head, but first walk away from the rover for two or three days.
