TDI top engine cover noise insulation?

I wonder if that explains why one of my TDI75's is noticeably quieter than the other two? Being the oldest (April 2002) I'd be surprised if the foam was still there though. Guess it's about time I had a look!

If the car does not have a tandem pump leak there is a good chance the foam has never been removed, the diesel destroys it. Only reason to remove it would be to work on the head area say injector loom change. The foam does deteriorate over time and some may well have crumbled away by now.
From my own experience, if the foam is missing and only the fibre cover is present I would say the car is about 20% noisier than with both foam and fibre fitted. If none are fitted then the noise increases by about 20% again. Not exact figures just my thoughts. My foam lasted intact until last year when a tandem pump was firstly resealed and then replaced... along with all the rubber hoses twice.

Hi, That would be great if you could have a look/listen and report back. Ive never had that foam but anything that quietens down things a bit would be very welcome.

Hi Guys,

Sorry for the late reply.The number 8Z2103954 fits AMF,BHC and ATL engines.They are on back order so roughly around 1-2 weeks and the best price including postage would be £72.00.

If anyone is seriously interested please feel free to get in contact or if you have any other "Group Buy" ideas please feel free to message me.

Thanks

Sorry mr stupid here - so I have an engine cover but I'm assuming this sits below the cover and sits around the engine block?

Ok so def interested - might well be 72 quid but if it noticably reduces cabin noise then its worth it. Love my little 1.4 TDI A2 but it isn't half a noisy child :)
