1.6K Series Water Leak....check yours!
Noticed a few weeks ago after the car was parked up in the garage for 24hrs a 10p sized blob of coolant on the floor under the engine!
AARRGHHH - Head Gasket!
I reckoned the worst, but then thought about it sensibly.
Compression check = good
Plugs = look fine
Misfire = no
Oil in water = no
Mayo on oil filler = no
Performance = still smiling!
....so started looking through web forums for a clue.
Turns out that early 1.6K series units with the plastic inlet manifolds had an inferior inlet manifold gasket material (black)....the gasket seeps and allows water to pass by it.
I checked the engine again and the water that I had seen tracking round the head joint was infact running down from the inlet manifold...and it has a black gasket!
...so I reckon Head Gasket fine (fortunately)...and £25 later I've bought a new Rover inlet manifold gasket (you need the green one) and new studs and locking nuts to fit it (instead of the set screws used originally)
All being well I should be doing the job this Saturday....so I'll let you know how I get on.
