Has anyone else tried the vacuum pump mod described by Jaguar3? Would be nice to have a confirmation on a different car  2011 Vogue SE 4.4 TDV8

I have done it but I can’t comment on whether it would have fixed the smoke issue as I had already done the secondary turbo drain mod in June last year, which did successfully cure my cars bad smoking habit. All I can say is that I did Jaguar3’s mod in November last year and have seen no bad effects from doing it. I just did it because his logic seemed sound and I wanted my scavenger pump to be working more efficiently. My car is a daily driver and I average 300 miles a week. 2012 Westminster TDV8 4.4 Indus Silver

Today I did this modification.
The oil connection was a bit difficult to undo. The push spots for the quick connector are not easy to push, so you need to rotate the pipe a little to be able to pressh two push spots inwards.

@mfcetin - any news on the vacuum control pump mod please

Dear all,

Sorry for the delay on reporting. I have been quite busy, mainly with our new born
I can definitely say that the smoke has significantly reduced but It is not totally gone.

Before the mod, I would get a big smoke puff after driving city for about a week. It was one large cloud lasting maybe 2-3 seconds

Now after the mod, once in a while i see some smoke if i accelerate hard, but its not that huge of a cloud as before.

To conclude, definitely worth doing specially considering the low effort. Just be gentle when you do the job. A new pump costs like 300 euros in Germany 😬 2011 Vogue SE 4.4 TDV8

Don’t use loose oil from the filler on changing filter if you block the drain hole with the bolt method 2012 Westminster 4.4 tdv8
