noisy kseries engine - MoJo
I have a rover 416 with 62000 miles on and which sounds quite noisy when driving as if it has piston slap.. I'm sure it hasn't got a worn engine but you never know. Other minor problems are that it holds its revs between gear changes and runs quite rough when the choke is on but sweet once warm.

Any ideas??

Thanks in advance,

Mojo

What year is the car? Earlier 216/416 didn't have the K series, but a Honda engine. A friend of mine had two of these, and they both sounded terrible, especially when cold,, as if someone had left a load of spanners inside the cam cover. But they never blew up despite the most horrendous abuse.

Its a '97 with the k series engine.. the engine sounds fine when revved through the gears but round town sounds very intrusive for such an otherwise quiet car. The fact that it holds it's revs between gearchanges puzzles me - I have seen another thread on here about the same thing but he had no replies.

I have noticed this tendency to hang onto the revs between gearchanges in a lot of modern cars. I suspect it is deliberately programmed in to make it easy for bad drivers to change gear smoothly. Try forgetting all your previous experience, and change gear as if you only passed your driving test last week. I did a fair few miles in a Mk3 Golf, and found this was the only way to make smooth progress.

A slack timing belt will make the engine sound noisy, check/replace asap. The reason that modern engines hold revs between gears is to reduce the emission of hydrocarbons from the exhaust when you shut the throttle. Unless it is excessive i.e. doesnt drop at all, it is easy to live with and makes for quicker, smoother changes.
