Hi guys

Finally got around to using a 5Alive EGR blanking kit on my TD5 110 today. Also cleaned the (absolutely filthy!) MAP and (not that bad) MAF sensors.
Took it for a spin and the increase in acceleration/power was great but now I can hear a very noticeable whining / whistling a high revs... :o
Have checked the mating of the blanking plates and there doesn't seem to be any gaps / flaws that would allow air in. Checked the vacuum hose and it too is blanked off correctly.
I going to ask a mate tomorrow to rev the engine so I can try to see where it's coming from. Anyone have any idea what I might have done wrong ?

Thanks

might be an idea to post your sound on here.

Because a friends TD5 that was chipped with a straight through exhaust used to whistle a lot but was far more noticeable on tick over.

Did you put the blanking plate on the exhaust manifold?
I should imagine if you didn't seal this up it would whistle

Hi djam1, yes used the blank plate provided in the kit but it didn't come with a gasket... Though the original didn't have a gasket either...

Cheers

Don't know if my phone would be able to pick it up too well but will give it a shot tomorrow..

Mine fitted fine from TD5 Alive, no whistle so not sure whats going on with yours? I have only noticed a whistle after fitting a decat and centre box removal pipe but this I'm told is normal :D

Have a look around the blanking plate you fitted for black soot or get someone to listen under the bonnet , If there is trace of soot it will be leaking ,some maniseal on the plate will solve all leaks;)
