Thread: Catch can install on 2016 Discovery SDV6

Most people talk about it and don't do it as the filtering out of the factory is excellent and little to no oil vapour gets into the intake.

Some have discussed installing a secondary water filter on the low pressure diesel feed though I don't think any have completed it.

I was recently GOING to get it done with my remap but was convinced by the experts at M.R Automotive that it's a waste of money... filtering is already superb and there is almost no blow by. Saved me 480 bucks.

Both have been done and discussed here. Good information in these threads:
Oil Catch Can for D4
2.7 fuel filter flow rate ??

I can't help regarding a catch can. We have just returned from a trip including the Anne Beadell Hwy and I investigated fuel filers for my MY15 SDV6 before that trip. ALL4X4 in Newcastle recommended against fitting any extra filtering (I think due to the difficulty, the potential adverse impact on the existing system and the effectiveness of the existing system).

They recommended to carry a spare filter and know how to replace it. So I got my UTube degree and also got their mechanic to show me how while the car was getting an oil change.

The key thing with fuel is not to put contaminated fuel into the tank in the first place. They also did not recommend the Mr Funnel filters as they are too slow for filling a vehicle. Ok for a Jerry can. I have learnt from a few sources, including a fuels problem consultant to major fuel users like shipping and transport companies, that the best method is to check the fuel before filling the tank.

Use a clear container to put a half litre of fuel into first. Check it for clarity and smell. You will see if sediment, water or black bio sludge is present, and the smell also detects for bio problems. If it doesn't look and smell right, don't use it.

The fuels Consultant does this every fill! Even in town. He is paranoid about fuel contamination as he comes across it everywhere in his job.

worked for me but all fuels passed the test.

PS the Disco handled the ABH very well and we had no problems.

Some good points thanks. Carry a Mr Funnel to use if the results of the clear container test show contaminated fuel & you absolutely have to use the fuel.

HI Guys. Just recently I talked to the guys at All 4x4 Kotara on fitting a catch can to my 2012 Disco 3.0l. They did not think that it is possible to do considering the factory setup. They also showed me a D4 TDV6 (2.7) that was in for some work. The intake track was approx. 1 quarter blocked with black gunk. so there is definitely blow-by. He also said that blow-by was worse on the 2.7 than the 3.0l & that the short trip vehicles worse than Country cars. I hope this helps

That is not blow by - that is the standard gunk that builds up from the EGRs feeding exhaust back in to the inlet manifold on overrun - well know and happens to all diesels with EGRs irrespective of brand. This is why you need to clean your MAP sensor near the oil filter on a regular basis.

If you blank the EGRs you do not get that gunk - do a search on here related to blanking EGRs and removing the butterfly and you will find one of the dirty jobs you need to also do is clean the gunk - the black gunk takes a week to get out of your skin - so gloves are a necessity. Funny, other than the MAP it doesn't seem to impact on engine operation all that much.

Thanks for that Garry. I found out the hard way with that gunk on my fingers
