Quick question. Are all C5 motor mounts hydraulic or are some solid rubber? I havent seen any fluid leak from mine and they looked fine when I had the motor out 6 months ago or so. I have a cammed motor that shakes pretty good so its hard to tell if theyre worn I guess. Just wondering because Ive seen solid rubber and fluid filled oem replacements.
And yes I am aware of other aftermarket solid replacements. Just curious about the stock ones. Thanks.
I'm pretty sure they are fluid filled. That's a way techs look inside and quickly say "motor mounts are bad". I know I've seen it a lot. I think it's the same for the C5
Yes, they are hydraulic. Beware the cheap OEM replacement style (Anchor) mounts that claim to be solid rubber; I ordered them from Summit and they were hydraulic too.

I did see those. They list two separate part numbers, one for the solid and the other for hydraulic. Was this the case for you?
Yep, I ordered the SR part number, for Solid Rubber. Took them out of the boxes and shook them, I could hear liquid sloshing around inside. I called Summit and they actually sent a guy down to the warehouse to shake the rest of them--all of the ones that were supposed to be solid rubber sloshed. Awesome support from Summit, but junk parts. I don't know if it's a bad batch or what. I'd call them first before ordering to see if they've fixed the issue.
FWIW, I quit messing with Anchor and ordered brand new OEM hydraulic mounts. They don't slosh at all. So they must be completely filled with liquid, while the Anchor mounts must have some air in them that allows the liquid to slosh around.
