Engine will be turbocharged and on LPG, can somebody please reccomend an aftermarket seal and a place to get them.
Check if you have the standard size boss where the seal pushes over. If it is standard, and you only run single springs, the felpro umbrella seals will be fine.
If you have double springs and dampner, or it is allready machined, you will have to get the other type. Either similar brown ones, or the teflon type are good.
Needs measuring, and then ringing a shop to check the new seal sizes.
Tefon type would be best with turbo/lots of heat. Ring VPW or Rocket.
