Hi,
Think I've got a burnt valve in my 1991 Cooper s. Are there any tutorials or u-tubr videos out there to enable me to tackle this myself. Thanks in anticipation.

You didn't say why you think that you have a burnt valve. Do a compression check to isolate which cylinder is suspect. Then do a leakdown check to determine if the problem is the intake valve, exhaust valve or rings. An air leak at the carb would be intake valve, hearing a hiss at the exhaust pipe would be an exhaust valve problem and an air leak at the oil dipstick would point to rings.

If you do have a burnt valve make sure you find out the cause of it to prevent getting same again, I had a burnt exhaust valve caused by incorrect advance curve in distributor

Type "BMC Classic Mini Workshop manual" into ebay................They are usually about £15/£20, or there will be lots of Haynes ones.
If you are young, you can probably find the Pdfile of the 1990's manual on line.
Changing a valve is something that you can do your self with fairly simple tools, by which I mean spanners and a feeler gauge etc:, not a hammer and pliers.
