Recently I noticed a repeatable small clunk noise from the front left engine area. The car does not always make the sound. When it does I can disengage the clutch and re engage three clutch and it makes the sound again.
I suspect it may be an engine mount. Is it possible to inspect the mounts without removing the bottom skid plate?

Lower rear engine mount is notoriously weak. Most peoples recommended first mod is to replace it with a stronger aftermarket unit. There should be a thread about it around here somewhere...
somewhere down that long thread it got hijacked. There is some talk about the engine smacking the firewall on hard takeoff (drag racing). I am accelerating quite slowly. I would only expect noise if one of the mounts had torn badly. It looks like you need to get the car up on a lift and remove the skid plate to inspect that portion of the car. I only have a driveway/garage to work in. It's snowing right now so I'm not going to climb under today.
Does anyone have any other ideas what it might be?

Spray some WD40/lithium grease on the Airbox 3 rubber mounting points. Stopped my noise. Check it first by moving your air box around. Had the noise for months, took 5 minutes to make it go away.

I recently had a similar problem on my SEL, also in the left front. Turned out it was the grommet between the airbox and the hose leading from it. It'd make a clunky noise if I stopped quick, went over a curb or sewer cover. I put some silicon goop around it and its resolved.
Might want to check that.

that's good advice. When I get a chance I'll give it a try.
