I don't remember the price, but I have done the tensioner replacement on many 400 & 500E's and it has worked.

The other thing we see is for the check valve in the oil canister to leak down.

I think the book time on the timing chain tensioner is about 2-3 hours or so.

The time on the belt tensioner is about 1.5, I think.
