I blocked the little nipple that the engine pad vaccum hose connects to on the valve.

My 2002 V70 D5 makes a "plop plop" noise when I take the filler cap off too, but all the mounts and pipework are in good shape. I just live with it.

Tbh i can live with the plop plop but i cant stand that theres quite a bit of oil leaking from around the vacuum pump.

Fix the leak on the vacuum pump, that may well fix the popping ,

Will call the local volvo dealer tomorrow and see if i can get a seal kit from them.
Will begin researching how to take the vacuum pump off in the mean time.

I DID replace the two gaskets on my vacuum pump (8658101 and 8658102). It is not so difficult a job.
However the popping noise is still there.
I know that I have brake booster seal failure and that might cause it.

Okay, just ordered the seals off skandix, now, how the heck do i get the vacuum pump off the engine? Do i need to take the high pressure fuel pump off as well? There seems to be very minimal room between the two.
Havent found much on google either.

You don't need to touch the high pressure fuel pump.
Remove the air filter box and the fuse box and you will have enough clearance to remove the vacuum pump.
