beat to death yes, but definitively figured out - no! (at least for this
van!)
I have been to your website may times (fabulous and thanks) and searched the
achives many times. Below I have a list of all that has been done.
It is mostly everything every discussed. That is why I am so frustated.
Better, Absolutely. Fixed - well no.
My question now is what can I expect? What was the result of all the
discussion? Flat out I ask, Should the sound/tone be the same at 3,000
(no - drone) as as 3500 (drone) - like it is a modern car? Has this been
achieved in any ticco powered van?
If so I want that quite ride in mine! I simply cannot stop.
This is the list of fixes installed on this van:
w/ free hung exhaust per McClean (from list)
w/ cat support bolted directly to engine block (ie no rubber)
w/ rubber mounted alternator bracket per someone on the list (from list)
w/ mastic rubber sheets on body metal (from list)
w/ drivers right side forward engine support bar rubber bushing welded (from
list)
w/ custom weather stripping on all doors to make door joints "surface flush"
and help eliminate wind noise (not from list)
w/ extra muffler hangers on the manifold to make sure it is not resonating
(not from list)
w/ 2 pieces of sheet rock laying flat on van floor to help eliminate sound
from floor (not from list this is temporary!)
