My dilemma now is what to do with a broken glow plug that will probably take a bolt extractor to remove. I started a second thread just for that.
Do you need to remove the plug?
I mean't what make/ composition gasket did you get?

Parts just arrived from Rovers North via FedEx. Headed to Zinola's, a highly recommended machine shop to remove the glow plug and check for warpage. On the way back going to pick up the 4 new glow plugs Winchester Auto Parts was able to find for me.

It's all coming together, this should be re-assembled and tested tonight.

To check for warping you can use a sheet of glass, in case
you don't have a good ruler.

Since the head is off, you might as well fix the glow plug, but realistically, it has to be pretty cold to need them. Mine will fire up in 40 degree temps without waiting for the plugs to warm. 3 working glow plugs would be more than enough to get the engine to start.

I'm not advocating lax repairs, just a point of reference in case someone can't get a plug out and doesn't want/need to pull the head.

It's already at the machine shop getting removed and tolerance checked.

The real question now is if it's out of tolerance, the overhaul manual says it's done. However can I have it resurfaced and be good for a short while?

thats a surprise. "done" should be defined as the bottom/base height of the head being too close to min thickness where shaving would reduce it to below min. i recently had my 2.8 head shaved as it was close to min but still enough.

I'm surprised there is no allowance for machining in the factory tolerance. That's pretty common on cylinder heads. Perhaps it's because of the high compression of the diesel.

Personally, I'd have it machined and give it a go. All you have to lose is a head that is technically no good, and a head gasket. IIRC it's not uncommon practice in the UK to have them machined. Maybe Diesel Jim can weigh in with another opinion.

here is a relevant thread on the surfacing question. http://archive.difflock.com/discus/m...s/5/89992.html

i should also mention that when my shop was machined, they bored the injector holes a little to make up for reduced clearance from surfacing. uour shop should know that.

It's a matter of how much out of tolerance ( if at all) it is which in turn dictates how much stock removal is required. Ideally, you would only want to skim the surface to remove any distorions and provide the smoothness without altering the compression or valve clearances.

It was 5 thousandths out. He's gonna skim it and we will try.

NEW PROBLEM- The glow plugs the local place gave me were totally wrong. So now I have a gaping hole where the broken glow plug went. Rovers North is past their overnight cutoff, British Pacific doesn't have any.

Ship's Mechanical in Portland has some on the shelf, but doesn't have the time to overnight one. I am desperately trying to find a glow plug. Everything in the Bay Area (Local dealers [duh], Cerrones, and West Coast British) were not helpful.

From what the others have said, it sounds like you can just plug it. Get a bolt the right size/thread and cut it to length

Have you reached out to any of the local clubs?, RDS, TNTLR. Other TDi owners may have a spare in their stash?

We are almost to that point. British Car Service in LA may have one we can scavenge.

Otherwise we will have to plug with a bolt.

NCLR for sure. In fact I had lunch with one of the BoD members yesterday.

I have a 200 that is going no where fast.
I'd be happy to pull a plug if it will get you back on the road!
