I wanted to post what size I found the o-rings to be on VVL solenoids for the newer 3.6L engines. You can't just buy the damn o-rings, you have to buy the entire solenoid. I don't own a Jeep, just a Durango with the V6. However, I found some info on here that was helpful to me. Just wanted to give back and hopefully this will help someone save some $$$.

13 x 16 x 1.5 mm

While replacing a camshaft I accidentally damaged one of the VVL solenoid o-rings. Since they've been installed there for a while the o-rings look flat so it's hard to measure the exact size. I ended up having to order a whole new solenoid. Before installing it I took measurements of the o-ring.

One thing I noticed while reinstalling the solenoid. The upper o-ring position (holding the solenoid in its normal orientation) is slightly bigger. Maybe 1mm or so. This allows the bottom o-ring to not get torn or squeezed by the upper o-rings machined position when removing. I looked at both o-rings and the upper one appeared slightly larger. However I think it's the same size o-ring and it's just slightly stretched. When I put the o-rings back on, the upper one fits tighter than the lower one. The lower one can almost spin freely in its notch.
I'm going to measure the oring notches of my old solenoid with my calipers later today.

Also, I would have to guess these o-rings are made of Viton (FKM). Seems to be the right material choice for engine temperatures, durability and synthetic oil exposure. Anyone agree or disagree?
