Don't apologise for your coverage of Rover 75, I'm loving it. These are the cars, along with Vectras (I may be in the minority, thinking that was a good car) and many others, that are still readily available for not much money, offer great useable daily transport and stick 2 fingers up at the scrappage system. You're inspiring us cos we can't go out and find a useable Fox, Invacar, GSA, 2CV for 500 quid but there's plenty of very good 20 year old cars around still. Bangernomics is king 👍

My Lexus gave up when I was in Galway on business . I stripped out the EGR in a lay by and took a bottle of ether which I had in the car (business purposes) and some pipe cleaners and painstakingly cleaned out the incredible gungy detritus in the valve . What a mess !!!!! However it worked and back I drove to Glasgow without problem . Never touched it again for the remaining 80k I had the car . EGR on all diesels of that vintage were and are a problem . Great video . Keep up your brilliant work .

This was a great video with a superb commentary. I think you are a good mechanic, not ham-fisted. It's dead easy to break a spigot of brittle plastic by accident. Nobody can claim that you don't get stuck into complex areas. This engine really interests me because I have a Land-Rover Freelander 1 with the same and was told the EGR and manifold needed cleaning out. Brave work on a "modern"!

Somebody bought me gloves and the first thing I did was snap off the washer bottle as I was undoing a nearby bolt. Bare hands for me I'm afraid.

[@davethornewell7417]

After working at a Rover dealer for a number of years, we saw a large number of 75's as well as other models, I can't say that we had many egr valve problems, though pcv valve filters clogged up quite often, you can get the filter screen separately, or if you buy the complete unit, the Landrover version was generally more expensive. One reason for lack of power was the mass air flow sensor getting coated with salt from road rain water spray, the sensor is available with or without the housing, a while ago when they went on back order, a factory fix was to wash the sensor with de-mineralised water, then dry it with low pressure air, though the sensor is fairly fragile.

I've been through a 2.7 5 pot diesel engine that couldn't pull the skin off a rice pudding. Changing EGR valve and vacuum modulators made a massive difference. The EGR valve was sticking open and really blunting the boost cycle and the vacuum modulators were tired and just didn't respond very quickly, if at all.

[@jtothew4201]

The egr is for particles that aren't measured in the MOT in the UK it's for the EU test. There isn't anything on the test for the egr to be checked. Blocked mine about 3 years ago and the emissions test as MOT time hasn't been an issue. My MOT tester actually suggested I blanked it off.

[@ShedTV]

Good work, Ian. When my wife and I had Freelanders I did this job regularly and would clean everything on the low pressure side as much as is possible. I eventually replaced the PCV filter (which was always sodden) with a modified maintenance free kit costing about £20 on eBay, it made a world of difference and kept the air box free of oil. Also, look out for rubber hoses softening due to oil contamination which can start leaking leaking to poor turbo response.

[@andrewlaw]

I did the EGR on my 08 Passat, it was clogged solid with crud. The anti shudder valve had to come off first and that was exactly the same. 2 cans of EGR cleaner and 3hrs later they were pristine again. Made a big difference in driving and black smoke under throttle though.

Alway's good to have a few 20th C. cars around when working on a 21st C. car. My experience has been that working on modern cars (yes I do consider the 75 a modern car as it was very modern at its time) is you tear it apart, then work out all the parts you need to put it back then wait for everything to arrive (who knows how long) and reassemble.

[@profrumpo]

Very interesting, Ian. Now I really know why I hate new cars. On my old carbureted V8s, 2 bolts, one vacuum line and EGR off. Cheaper to buy new that fuss with an old one. PCV system was a $10 fix for new screen, valve, and filter. To do both was a 10 minute job. I have to do the PCV on the 90 Volvo. From what I read, the flame trap and oil separator are a right pig to get to. Oh, well.

The Rover engineers improved the BMW M47 engine and it was redesignated M47R for the Rovers. Cleaning out the intake manifold is a worthwhile job but it’s a very mucky task. Those plastic T pieces do get brittle and you have to be careful, I replaced mine with brass ones. Sometimes worth replacing the small return feed pipes too as they harden over time.

[@ficerion6478]

I cleaned the EGR and intake on my E39 as I was blanking the infamous swirl flaps at the time, both equally had carbon buildup similar to your rover. Breather filter was also well overdue, they do seem to get overlooked on these engines.

[@VDPEFi]

My wife had a 320d with the 'same' engine. When it was good it was excellent but it had lots of problems by 130k miles. Our old Kia sorento has a vacuum egr and no map sensor so you can just pull the hose off and it's disabled, no warning lights or anything. Old school! Try not to get too much chemical wise in the vaccum port, it will mess with the diaphragm. Also, I don't know if the upgrade is available for the rover installation, but the later m47 in the BMW's had a 'swirl' type seperator that does away with the cotton element. It is allegedly maintenance free and helps protect the turbo etc.

The 1.8 petrol engine on the Freelander had had the remote thermostat added, but the old one had also been left in place instead of being removed and replaced by a spacer. This had been done at the dealer in Stratford-on-Avon before I owned it....good job I checked the work!! There are two EGR valves on the diesel ingenium engine...a high pressure and low pressure valve.

All the recirculation systems got gunked up to the point that my E60 idled like a bag of spanners in a washing machine, so I had them all replaced; some pipes were almost solidly blocked. The transformation was incredible - not so much in terms of power, but economy. Suddenly a deliberately slow (55-60mph) dual carriageway run was returning just over 40 mpg. On a 3 litre petrol car with a quarter of a million miles on the clock.

[@Azurael]

My 525d (M57TU, a close relative of the engine in your 75) seems worse since I cleaned the EGR valve. Suspect it was stuck closed before. I'd have blanked it off but apparently the ECU being aware of that messes up DPF regen. I'm still glad it has a DPF since I feel bad enough driving an old-ish diesel as is though. I did blank off the swirl flaps. Not sure the pre Euro-4 engines have those, but I'm glad I did since they were disintegrating and in great danger of getting sucked into the intake.

I must take issue with your comment on the swirl pot PCV. I've had mine on for two months and it's clean as a whistle. A friend with a TD4 Freelander did his swap around three years ago, again, it's spotless. The idea is that it cannot get restricted or blocked anything like the sponge filter. Trouble starts when people use cheap oil or simply don't service the car properly. The old-style filters were getting missed during servicing and this, in extreme cases, was resulting in some cars blowing turbo oil seals due to overpressure. Don't fear doing the modification, a quick look at it during normal servicing will put your mind at rest. All the best, and continue enjoying a great car. Jim.
