hi mate, like your Mg, im a big fan of rovers, thats the 1.4 engine you have
cracking engine the K, probably the best their will ever be, parts are still avaliable from most dealers and rover, well, ex dealers,and x power too the best forum for rovers is
www.mg-rover.org as mentioned above.
Just respect the engine, what i mean is to service it every 6,000, the manufactuers state 12k but it will last for a long time if treated nicely
The k loves 10w40 magantec, do not be tempted to put that slick50 in the engine, its a slow death for them.
In terms of tuning, the k is one of the most tunable engines around, dont be tempted to put a filter on the end of the throttle body, this serves NO purpose as not only do you get heat soak, it can also be related to the pulses of how the air travels through the engine and bouncing off the vlaves, cancelling the postive pulses, just go for a replacment panel filter as cheap open filters do nada for the K as the airbox's are pretty much set up well.
Ditch those crappy solid brakes, go for the mgzr160 setup, a cracking up grade for the 1.4, straight bolt on, just buy new discs and pads.
Problem areas:
Leaky camshaft cover gasket - £8 from a motor factors, 5 min job
Rust from boot hinges - go out NOW and put copper grease or vaseline on them and leave it, they may well rust
Headgasket probs - check coolant every week, any noticable drop must be investigated, any signs of the coolant gauge moving up just above the half way mark, STOP as soon as, turn the engine off
After a taxing drive, let the engine cool! its not a fiat where the fan comes on, leave it to idle for 3 mins before shutdown
Dont worry about tappet noise from a cold start, this should stop after 3-5 seconds (worse case really) of start up, any longer usually indicates that the oil and filter *may* need changing
The k loves to be revved, 103ps from a 1.4nasp, thats saying something aint it? bugger all weight, watch the old girl fly in second gear waving goodbye to n0bs driving up your bumper hahaha
K man.
