annoying knocking noise coming from engine bay - declantg - 27-12-2011
Recently my car has decided it likes to knock whenever i either speed up or slow down and it will knock quite loudly if i come off the throttle.
Originally thought it could be engine mount?
Any ideas would be a help

Have a ganders at your engine mounts. Normally bottom one to knock. If they all look fine, get the wheels in the air and see if you can find any play.

Bottom ones arnt the nicest because the o/s driveshaft has to come out. If its either of the top ones, there quite easy.
Just don't do what I did and drop the gearbox mount without anything under the gearbox lol

Quite cheap to replace the mounts?
Re: annoying knocking noise coming from engine bay - Niall - 27-12-2011
Gbox mount was 8 quid, top was 12 and I haven't done the bottom but it should be cheap. Needs pressing though.
Re: annoying knocking noise coming from engine bay - declantg - 27-12-2011
I hope so

Sounds like bottom mount or a cracked chassis around the top mounting point.
Grab the top of the engine and rock it and see where it moves
Re: annoying knocking noise coming from engine bay - declantg - 27-12-2011
a cracked chassis doesnt sound so great!

Not as bad as you would think. Will only take a couple of minutes for someone to weld up.
Re: annoying knocking noise coming from engine bay - declantg - 27-12-2011
Just checked it and rocked it forwards and back, right hand side has more play
Re: annoying knocking noise coming from engine bay - td_dan - 27-12-2011
Thats what iv got. Gonna weld it tomorrow

can you feel the knock through the gearstick and steering wheel? could be subframe bolts coming loose.. mine came loose during an autotest once, thought it was a snapped engine mount until i lifted off on the way home and the steering wheel started moving back and forth..
