help diagnosing this one!

Mine is the same. Cabin vibration, seems to be coming from everywhere. Always happens at 1500 rpm if I let the T2 labour - whichever gear I'm in but mostly 3/4/5. The old girl just does not like being worked that low. As soon as it starts, I drop down a gear to keep the revs at or over 2k - she's well happy then.

I've put it down to having to modify my driving style. A 2.7L, 4 pot diesel lump is just not as smooth as a smaller displacement engine. With the right revs tho she will tow a block of flats without breaking sweat. :thumbs

agreed. I did some test driving today on my way into work, and yeah, im 95% convinced now most of the noise is my driving, the other 5% is down to the flexipipe and possibly a heat shield vibrating AND vibration from my wing mirrors!!:nenau

So, you can start enjoying driving it now Clivvy

yh, drive home today did the same thing, practiced my driving and paid attention, its definitely me:thumb2

ill sort the flexipipe, and rattily mirrors because they are adding to it but obviously they are ok if im not labouring the engine!

From my engineering days, I remember everything has a natural resonance frequency. It won't be exactly the same on each vehicle but will change with the vehicle's individual characteristics. The T2 resonance seems to be in the 1400 - 1800 rpm range. Mine is 1500 rpm. Other vehicles may be 1650 rpm or 1750 rpm. etc.

Above the resonance point everything disappears. Before I push the go pedal I usually check to see I am above at least 1700. Once the turbo kicks in its up, up and away.

I also found that the U bracket just aft of the flexi joint had a habit of rattling at idle. It didn't feel loose to the touch but it was. 5 seconds with Mr Mig sorted that. :augie

Also,you said that it was a while since you have drove your T2(Driving a Fiat)So remember a bigger engine revs less a than a smaller one ie the Fiat you have been driving.So just a few more revs whilst going up through the box.

exactly right! im getting used to it again now, and this mornings drive was much better. I reckon once ive sorted the flexi and whatever else itll be much quieter. It helps a lot that the engine warms up pretty quick since I did the coolant/thermostat!

yh that's a fair point, I have noticed huge difference between this T2 LWb and my old 97 SWB Maverick. They sound different, drive different and I think I was expecting something more similar with the LWB other than drive characteristics. I totally love this LWB though, love it!

I've owned dozens of cars over the years, this is my first T2. Its noisy, thirsty, sounds like a combine harvester when it first starts in the morning and has lots of quirks - but I absolutely love it. :clap
