Why I don't like [what gets done to] the Rover K series and

[hiscot]

I agree Simon but its a simple soloution to a known problem ( but far from ideal ) , I do not understand how rover could not work this one out ! or indeed fit such a poor pump in the first place 2k to 4k is poor
I expect if you have the man tensioner ( as you should with a tuned high rpm engine ) maybe you can fit the longer belt from the auto tensioner or indeed if looked into I expect gates may do a longer belt from another engine hence no revised belt tensioner required

I have seen a camchain k series or rather a camchain conversion in place of the belt. ( only a mock up pic )
I think this powertrain engine was going to use either a remote mechanical or electric pump as the chain tensioner blade runs across where the pump would fit I also hope it would be up to the job ,and that makes me think there may be a better remote soloution than the std rover product

The water pump is fine for a 1.2 shopping car...

Exactly, or a Honda k20 on the mway or a Peugeot whatever etc etc etc.

the pump is ditto to most OEMs - ie the Honda K20 is every bit as bad, and is always replaced with a proper pump in decent builds - ie Neil Brown, only a clubbman, have no idea, don't care, just wanna be paid engine builder would leave an OEM Honda or Rover open back impeller, 1:1 ratio pump on an engine.


Electric water pumps will NEVER do enough work to cool an engine unless you connect a big one to the National grid - that's why no serious engineer use them


Chains are a pain - they wear, they stretch, they require lubrication and they therefore involve losees

All F1 engines of recent times have been either gear or belt driven - none were chain driven!

Another engine builder who does care, commenting both expressively and technically on the standard of the work to which the K series engine is so often subjected in this country.


- It is worth saying that not only would this engine have run - for a while, but many similar engines from this source [the out of round bores are an absolute constant] are running, but with the same issues, that deny them the power and torque that their cam/valve/induction/exhaust spec ought to give, but that their lives will be much shorter than they might had they been built correctly.

Finally many such blocks and components with the same all too familiar issues have been built up by other 'engine builders' who have bought the parts, and who have on occasion complained when hideous failures happen - or the client complains, but otherwise will not take responsibility for building engines with parts of this quality which to my mind is absolutely wrong - !


The faults that are listed here are not the result of shoddy workmanship, they are proof of a clearly inappropriate methodology and fundamental lack of engineering knowledge, which is why the faults just go on happening.

The attitude to the customer is something I have seen so many times from several sources, - one 'tuner' even goes to the extent of requiring his clients to sign a non disclosure agreement to gag the client, and prevent it coming to the forums - see previous posts here .


here is the thread ;-

- I do wonder


I have been pointing out these issues for years , and have just been vilified for it - look at the comments on seloc now running in the thread about this blog -

yet for instance the cack handed and just plain will never work way, these people hone out the bores is not only still going on - but there is a single apologist on seloc - he thinks he was lucky - when in fact leaky rear crank seals are a typical symptom of this issue - bad ring/bore seal = high crankcase pressure = leaky seals and I know this individual had leaky crank seals - the point being that it is this "tuners' methodology that causes this problem amongst ALL the other problems, and despite the fact that this and other issues were flagged up years ago, people think "interesting read"


uuuuugh!
