Engine change - Now a knocking!


so iv had loads of problems with my 147 which resulted in an engine change. All went good, until we got it back together.

When you rev hard and QUICKLY come off the accelorator there is a knock. It only knocks once after each rev, and comes from the back left of the engine as the engine moves forward.

Could this be a problem with one of the mounts or is it a possible problem with the cylinders?

Just to note, the engine was run before it was installed and there was no problems.

Check the counterweight on the gearshift as I have seen this on a gt and it sounded heavy like a mounting but was the weight hitting the firewall...
