Direct replacement engine oil breather separator for 200 or 300 Tdi with internal baffles.

Available in colours, silver or powder coated satin black.

Lifetime warranty

Manufactured with CNC machined billet aluminium mounting flange and hose connections, supplied with Nitrile O ring and stainless steel fixing bolt.

Engines need to breathe crankcase pressure to atmosphere and most are designed to re-enter the air intake system after the air cleaner. Standard breather pots use a gauze and mesh design which over time becomes blocked with oil deposits, reducing the capacity to release crankcase pressure and also allowing more oil vapour to enter the intake system.

Our high performance replacement is designed to effectively reduce crankcase pressure build up on Tdi engines by using an internal baffle rather than the standard gauze and mesh design.

Our products are designed to have a practical purpose offering an improvement over the original black plastic units, as well as looking great in the engine bay.

The unit is designed to fit all Tdi engines including 2.8 TGV. Now with our new integral O ring-seal design which requires no extra sealing compound.

As with all our products, the AlliSport alloy oil breather/separator pot is designed and manufactured by hand in-house and is fully TIG welded. Please see our other alloy tanks, reservoirs and intercoolers to improve the look of your engine bay and enhance your vehicles performance.

    Vast improvement

  2. Nick Southwick

    I contacted Allisport direct and ordered an oil breather cyclone for my Land Rover Defender 300tdi, I was told that they were out of stock at that point in time but would be manufacturing a new batch and would post one to me early the following week. The following Wednesday the unit arrived via UPS. On inspection I found it to be of excellent quality and very well-engineered. It has now been fitted to my Defender and besides looking great it as stopped the annoying oil leak that I used to have from the old plastic oil breather cyclone fitted to the 300tdi engine.
    Thanks to Andrew Graham and James Orton of AlliSport for their help in this matter.

  3. Joshua

    Definite improvement. Love the look with all the other allisport additions to my 200tdi.

  4. Jeff Jones (verified owner)

    Works really well, and adds a clean finishing touch to the motor

  5. Benjamin Olson (verified owner)

    I have always had problems with the breather cannisters on my 300 tdi, after the last diaphragm failure and ridiculous James Bond like smoke screen … I finally broke down and bought a proper unit to solve the problems once and for all. thank you Allisport, it’s fixed.

    Lovely piece of kit far better than the plastic one

  7. Darryl Pooley

    I ordered a new oil breather for my Defender 200Tdi on a Friday and it arrived on Saturday morning such great service. The unit is a vast improvement from the old plastic version, and the slight leak I had before has now gone. A huge transformation within the engine bay nice and clean and such a leap forward. Thanks to Neil and Jess.

  8. Gary Lynn (verified owner)

    It’s not just shiny on the outside. The performance and the look of the oil breather separator are world class. It is an outstanding and reliable product. I highly recommend the upgrade. Thank you!

  10. Dave Jeffries (verified owner)

    Does what it says on the tin ! – looks great and does what it needs to !

  11. George (verified owner)

    Craftsmanship is excellent and not only has it improved the aesthetic of my engine bay, the function of the breather is a vast improvement on the stock plastic one. It can also be noted that the geniune interest of the Allisport team in vehicles is very obvious and shines through in every interaction with them, both before and after sale service is top notch.

  12. Simon (verified owner)

    Excellent quality product as usual from AlliSport. Fast delivery, well packed.

  13. Matt Unsworth

    Excellent well made item, really compliments the 200tdi engine bay.

    My only complaint was that the fixing hole for the M6 set screw did not line up to the threaded hole in my rocker cover and had to be enlarged by 2mm which was an inconvenience and resulted in me putting a scratch onto the body of the filter. (Genuine Defender 200tdi engine).

    • Andrew Graham

      Thank you for taking time to send a review. The mounting flanges are CNC machined and we use a genuine rocker cover as a jig to ensure holes are accurately in the correct position, so I am not sure why yours appeared to need modification.

  14. Jeffrey Taylor (verified owner)

    you can not beet the quality off alli-sport products

  15. Jonathan Goddard (verified owner)

    Good looking effective product.

  16. Atle C. Gandrudbakken (verified owner)

    It added nicely to my extensive collection of Allisport items 😉 . Worked as expected and as always !

  17. Paul (verified owner)

    decided after a few months of weather to buy the breather or not but in the end I decided to buy one arrived quickly and the quality is outstanding but unfortunately I’ve not fitted it yet because by ninety is off the road with a crack in one of the bores but soon as its fixed I will get the breather put on

  18. Paul Gunning (verified owner)

    Quality fit and finish, all parts included to for a direct swap with the OE unit. Has solved my oil leak from the old OE breather tank, and has improved the look of the engine bay.

  19. T.O’Callaghan (verified owner)

    excellent quality and a perfect fit and works better than the standard breather.
