Which flushing oil do you use? (I'm thinking of trying some in my V6 before I put the good stuff in).

Ah yes - good old Comma, I always liked their stuff. Amazon is probably as cheap as anywhere. £16.86 5L - https://www.amazon.co.uk/dp/B00OIPZ2...v_ov_lig_dp_it

I just bought some.

After 2 flushes and all the other things I've done while still looking for the misfire cause, the car is running mint now. However, I have one more question, I want to make sure that this issue will not cause me any problems in the future, so, do you guys know if there should be something regarding the fuel pump to look at? For example I guess that the car has a fuel filter, and if so, is it serviceable? Also heard that some models have a fuel filter that has a common problem with some orange O ring? Just talking from what I can remember reading on the forum. If the car really has a fuel filter I'd like to look at that too just to make sure it's clean and letting properly enough fuel through, and if not, to replace it. Mind you I have a 2.0 V6 engine.

Another thing to mention, my mechanic drove the car and he told me that even though it's got 150hp it doesn't really feel like that, he said he feels something is not 100% right in terms of acceleration, which makes me wonder because I always replace the air filter sooner than neccesarry, also recently fitted new upgraded VIS motors plus a rattle free manifold, checked fuel pressure and compression which are both right, reader shows no errors and everything seems right, but it still has that quite lack of acceleration that a 150hp engine should have Any ideas what I should check?

Your year 2000 V6 2.0 will have the earlier type petrol filter which is non-serviceable and doesn’t require the clip like the later filters.

The V6 in 2.0 form is not quick and needs high revs to do anything. I’ve recently gone from a 2.0 to a 2.5 and there’s a very noticeable difference, more like an 827 if you’ve had one of those. So I don't think there's much you can do, just enjoy the sound and the cruising ability.

Regards

Your mechanic is right. Rover V6 engines are not as powerful as you would think, hope or pray for. Most people, with a few exceptions, feel there is too little beef.
And I agree.

That's excellent news and thanks for concluding this thread. Just to be clear though, as you had two threads running, is this an accurate summary of the outcome?
  • The misfire was an incorrectly gapped sparking plug.
  • The tapping noise came from the hydraulic tappets which responded to several applications of flushing oil.

Exactly Simon, that would conclude it all, the tapping noise is still there at about 20-30% intensity I'd say compared to before but it's barely unnoticeable now compared to before, so I'd say it's in a "safe" range for now, will see how that develops in the future.

Having a perfectly working Rover again (which is quite rare haha) really makes the owner feel joyful and fulfilled lol, I just love these cars.

Thanks Galambosi. It's worth noting that both faults turned out to be very simple; nothing wrong with the flywheel after all! Diagnosis is always the tricky bit. It requires a lot of patience and organised thinking. Fortunately you applied both (and it didn't cost you a lot of money either!).

Finding the faulty spark plug was purely luck haha, I would've never thought that one of the spark plug's tip would be bent since I bought new ones, as I said maybe I dropped it before installing or it came this way and I didn't notice it, I was taking out the plugs to make the compression test and then I saw it and I was like oh look how simple that was lol. Happily I noticed that soon enough and didn't spend more money for useless things. I have to thank you Simon and all of the members that helped with this issues again for your kindness, guys like you are the reason that most of these beautiful cars are still on the road and running!
