Talk Morgan Forums Thread Like Summary - Water problem

I haven't used my 92 4/4 for a few months , CVH injection engine,while checking it over I find the water in the expansion tanks feels thick and greasy and I wonder if i have a major problem it starts and runs ok and doesn't overheat. The dip stick shows full with no water droplets on it so.possibly not a head gasket.
Any ideas please or does it just need a good flush out and new antifreeze. It was changed about 3 years ago.
Thanks. Ken.

CVH engines should use old style Glycol antifreeze which will feel 'greasy', at 3 years old a flush and renew is due anyway
