I've said it before and I will say it again, that is an awesome shop. The photo is cool and I love the open feeling that the shop conveys.

Hey you guys didn't really want them to last forever did you???

last I heard was issue was being caused by thermocycling of the valves do to egr flow conditions.

this was from an fse about 8-10 months ago.
