noisy????

Post by Goodenough4U » Sat Mar 13, 2010 10:44 pm

i have an N reg bongo. its a 2.5 tdi. it needs some new belts but apart from that it runs really, with recent oil and filters.

my problem is, when i go up large hills and give it some revs its pretty noisy.

im not sure if this is because you sit on the engine and its a fair sized one at that or if iv got some problems?

Make sure the seat clips are tight, every single one I've checked, they've "stretched" out a bit meaning the seal isn't as tight. Easily reshaped with a bit of gentle hammer persuasion so that the arced bits of the clip are a tighter arc.

I notice a resonance at around 1750 rpm that appears to be intake induced, is it similar?
