Many of you will be familiar with the engine 4 bolt mounting on the chassis which uses 4 large diameter rubbers between the engine lugs and the chassis, smaller diameter rubbers and washers on the top with rubber tubes around the bolts through the engine lugs. This results in no metallic contact between the engine and chassis thus giving some compliance. The question is how tight should I fix the four bolts so as to retain them ok but not lose the compliance? I tried 15lb.ft but the washers under the top bolt heads sunk into the top rubbers. I have found some washers larger diameter than I used so that may overcome the 'sinking' but the torque question remains. Maybe there were special washers originally?
The front two bolts are tapped into the chassis but the rear two go through to locknuts underneath. Because the chassis holes for the rear two are nearer the side of the channel than they should be, a socket will not fit on underneath so molegrips there and socket on top! Possibly I could find a very thin wall socket.
Of course one cannot use a socket for the rear bolt head which is underneath the starter motor housing so I have to use a very small spanner with mole grips underneath!!
Nevertheless the main question remains as to how tight to try and fix those bolts? Making a judgement is not so good in this case.
