    With so many threads about vacuum pumps leaking and knocking, thought I'd do this DIY repair for those not wanting to spend 250-350 for a new one.

    Things you'll need:
    New o-ring
    Small hose clamp
    High temperature gasket sealant
    Torx bits
    10mm socket
    Small ratchet
    Sheet or towel

    Remove the cabin filter/housing - twist locks and torx screws.
    Remove the oil filler cap - clips off.
    Remove engine cover - pulls off.


    Wedge the sheet/towel down the back of the block to catch any oil and the bolts that you'll drop repeatedly!!!
    Remove clamp and hose.
    Remove the 3 10mm bolts securing the pump to the block.



    Remove the pump and make a note of the position of the square locking plate as it has to be in this position to fit back into the receiver on the camshaft!!
    Turning the locking plate will squirt oil out!!


    Remove the 5 torx screws.


    Open it up.


    Take it all apart, clean it all up and make it nice and shinyyy.


    Once it's all clean and dry, run a small ring of sealant into the rebate where the large gasket goes, insert the gasket and wipe away any excess sealant, then run a small ring of sealant around the outside of the gasket, make sure theres no sealant around the inside nearest the spinnig chamber!!


    Put the cog and rod back in.
    Refit the coverplate.
    Fit the new o-ring.
    Put the pump back on the engine.
    Spend an hour tring to get the locking plate back into the receiver!!
    Fit new hose clamp to hose, refit and tighten.
    Put the engine cover and filter/housing back on.
    Get the bus for the next 24 hours smiling at everyone because you just saved yourself 250 - 350!!!

    Excellent guide, careful with the sealant though.

    It's got to be high temperature. The first time I did mine I put the sealant on the edge but then impatiently tightened the cover and as a result, most of the sealant was spat out. I didn't think much of it but after a few weeks I noticed it was seeping oil.

    The second time I took the old seal out completely, put sealant on the outer edge and just sat the cover on top lightly, without pressing too hard. You have to give the sealant a few hours to semi-harden. Then some loctite on the bolts and tightened. The good thing is any excess sealant in the inner part will be trapped in the oring channel (now empty) and you can be sure it will never make it into the pump.

    I had the pump out after a few months (for a completely different reason this time) and there was no oil leak. I was able to source a few Viton rubber seals very close to the original size and thought I might as well put that one instead. But in any case, sealant will work just fine if done right.

    First post here but have be been lurking around for a while, just to say I did my pump today using this guide and fingers crossed the leak is sorted
    No more oil burning smell in the car yippee.
