Rover 600 - after fully filling with oil, engine revs invoulantory upon startupCause:Oil fill procedure was incorrectly followed which meant oil entering the crankcase breathing system. If oil is
poured into the engine too quickly it is a possibility that some oil will enter the breathing system. Then when
the engine is started the oil in the system may cause the car to rev briefly beyond normal range. Ensure
that oil is pour into the engine at a reasonable rate.


T series engines : 220/420, New 420, 620 turbo, 820
Cause:
Carbon deposits on the exhaust valves mean they stick open and cause loss of compression. Cause
can be short journeys that don't allow the engine to warm, and engine never reaching higher RPM.
Action:
Replace the valves with newer 'carbon break' valves(part number LGH101000). These are fitted to vehicles
after '96.
K-series engine.
Loss of power/misfire - valve sticking
Range:
111,114, New 214/216/200 Vi, New 414/416, metro 1.1/1.4 XW 214/414
Problem:
Loss of power and misfire is likely to occur while the engine is warming up but can also occur when it's
warm and while the engine is at various RPM. Likely to occur on cars that have done more the 5000 miles.
Cause:
Journeys that don't allow the car to warm up to optimum operating temperature and shorter journeys that
never allow the car to reach high RPM are a prime cause. The valve stems particularly the exhaust ones
become clogged with carbon deposits.
Action:
New carbon break valves should be fitted to replace the old. These new valve stems have a slight narrowing
to allow the small amount of carbon deposit which occur naturally to form without fouling.


try a good gas cleaner or take it to a shop to have a intake cleaner run throw it or with the car running take off the intake hose and squirt in intake carb cleaner use quick sort shots so the engine dose not die. if it does start it back up and repeat.

the rev counter might be faulty due to a leak or water getting into the electrics. Sounds like the car is fine once it has warmed up? maybe the electric choke is knackered.
