Hey Dennis,

I agree that the W7DTC is a bit longer, but I have been running them for years on my Vanagons as well as any Vanagon I have worked on.  So while they are longer, I do not think they are too long to the point that the piston will hit them.

Have you had personal experience where this has happened?

Broken spark plug tips and loose plugs are both indicative of an engine

listed as a fit for the '85 model year. I guess a mistake! Check your
ignition timing and make sure the cat is not plugged.

Subject: Broken Spark Plug Electrode/Tip

After my van suddenly lost power, I found that one of the spark plugs
(right/rear) was loose. Before tightening it, I pulled it: The tip is
gone
and one of the "electrodes" (bosch tri-electrode) is broken off.

Would simply being loose cause the plug to break this way?

I figure it wouldn't be such a good idea to simply replace the plug with
broken bits in there... So, what now?

Thanks,
