You can get off-the-shelf soundproofing from various sources. I imagine it might be something that frost (www.frost.co.uk) do.

grrr.... over reving problem is back :S ! ...
ive tested the vacuum valve with wires direct from battery..... its mechanicaly functional, however following green books ive done some checks and the current to the vacuum valve never moves from the low ratio side to the overdrive side im thinking that this is a microswitch fault stopping it changing up at the moment im having to put up with revs around 40000 when traveling at 30mph... not good ive had belts checked (good) clutch clearance (good) 4 way vacuum valve seems ok will probably change it to be 100% microswitch,,,, pretty sure its not working right will change it as soon as i source a replacement.. any ideas what to try next if changing the valve and microswitch makes no difference ?????? |

tachometric relay by the master cylinder ? you should hear it click when rpm gets near 2000 rpm when you listen under bonnet .
Vacuum leak from the plastic lines which go through the chassis , welding tends to melt them! The rubber Diaphragm in one side or other of the primary unit drums can perforate . The seals which seal the rotating union which let air in and out of the drums in the centre of the Primary unit drums can wear . the vacuum 4 way valve may well click , but the head of the rubber valve inside tends to fall off ! easy to dismantle and bond back with superglue , it gives you another 18 months of life from it .. Broken diaphragm springs in secondary unit .. etc etc . there are a LOT of things which can cause your problem ...

Have you already gone through this article yet? http://www.volvo300mania.com/forum-u...hp?f=6&t=12314 It actually describes how to investigate vacuum problems. Since a couple of years you can get an overhaul kit for the 4 way vacuum valve. Just have a look at article 3291047-R on http://www.born-built-beauties.eu/ht...n_par.html#CVT
