i never bother with antiseze on spark plugs and havent had a problem i wouldnt worry about it

I've never used antisieze on my plugs. Personal preference I guess. Should not be a reason to since you shouldn't torque them down to insane numbers, and if you change them regulary. Anyway, it won't hurt neither way. I would wonder a little about the crush washers though. They should never be re-used. My new plugs I got (AC Declco) doesn't even come with them. Looks like they re diesigned them to not need them. They are rounded off at the ends of the threads which I guess in theory evenly mates them to the spark plug hole.

I ALWAYS anti-sieze my plugs. It's cheap insurance against breaking one off in the head when the threads corrode (had it happen on a customer's Honda once.) My customers are also bad about going 120k miles between tune-ups so that's another good reason. Definitely don't reuse the crush washers, but if you used plenty of anti-sieze you should be fine without reapplying.

Some heads have a tapered seat design which doesn't require crush washers on the plugs. Others have a flat seat which does. That's why yours don't have washers Pneumatic.

ya i guess my plugs never seeing more then 10 000 km before getting changed means i dont have to worry. But then again thats part of the novelty of having a summer car

where can i pick up extra crush washers from would they have them at autozone, hardware store...?

would you happen to know if lg4's had that type of head that uses washers

They should be tapered seat plugs. Almost all of the iron-head engines were.
