Hi,

I'm in the fase that i'm closing the chain tensioner housings.

In Wayne's book he states that all that's used is a gasket between the covers & housing.

On a lot of 911's I saw that an additional sealant was used. (574 or some silicone based sealant). Is this a proven procedure to assure a leak free engine? Is the gasket alone not enough?

If so, what's the best product to use? 574, Dirko or Curil T?

Thanks Hessel
