Hi Guys,

Doing a search and this threat turned up ...

I was not aware my '91 350SDL had a trap catalyst ... does it?

Did you do the timing chain replacement? How hard? Noticeable improvement in any way?

Was going to note the sound you mention may be related to the accessory drive belt tensioner or shock ... 8 of the shocks have been replaced on mine. Getting ready to replace the tensioner with the hopes won't have to keep doing this.

George
