No, it's a rubber type gasket. Very rare for those to go bad. You can ohm the pins in the pass thru connector, and a visual inspection of the gasket will tell you if there are any issues, but I've pulled the valve cover on probably a dozen trucks and never had to replace a gasket yet.

I buy everything like that from powerstrokeshop.com. Best prices and fast shipping.
I 2nd there's usually no need to change VC gaskets. I did changed the under valve cover harnesses 'while I was in there' since they were only about $26 each (powerstrokeshop). I had the problem with connector coming loose (fixed it the way Chris described earlier) and figured it was good preventative maintenance since my rig had 240k at the time. The 'new' harnesses come with a much better clip design, so no 'rigging' was necessary.

Sounds like you have only 1 good glow plug. I'd suggest going ahead and change all 8. You've just performed the same test the mechanic did to determine you had faulty glow plugs. It wasn't really that hard to do was it?
Changing glow plugs is the same way. Intimidating at first, but after you've done it, you realize it wasn't really that bad.

a high ohms reading will mean a connection is broken in the plug. a .000 reading will mean the plug is shorted out.

I borrowed these pictures from Dan from his 99.
See the white wire touching the rod? If you move the wire, or remove the harness to inspect, the wire actually looks like this

yup. they are crap. if you are going to put them in, put $1500 on the side so you can have the heads pulled in 2 months time when the burn out and swell the tips, forcing you to pull the heads to get them out.

How much are you saving? The ZD11's retail for like $11 and Autozone sold 1000's for $0.01 year before last. Forever there were folks reselling them on flebay, etc for $5-6 each.
For me, if ONE person had to remove the heads from the 'inferior' brands - I wouldn't risk it. JMHO!
