98 1.6 How to find top dead center on a 1600cc 8v - Sean22
Im changing my head gasket and need to find TDC as stated in the haynes manual for the car. It says "Look through the aperture at the flywheel end of the engine and continue turning crankshaft until the TDC timing mark on the flywheel/driveplate is aligned with the TDC mark on the gearbox bellhousing." I cant see the timing mark on the flywheel/driveplate. Anyone know what this looks like or where it should be?

Many thanks,
Sean

autodata says the timing marks are roughly at 12 o'clock on the camshaft, corresponds to rib on rear timing cover and 6 o'clock on the crankshaft with the crankshaft sprocket keyway at 12 o'clock.

if you really need to find tdc, remove the spark plugs (makes turning over by hand easier) and put a long screwdriver in cylinder 1 hole, as you turn the engine over the piston will push the screwdriver up as it approaches tdc, tdc is the with the screwdriver at it's highest point before it starts to lower, you'll only need to get this roughly right as once you have the head off you can adjust it visibly as you'll be able to see exactly where the piston is, if you do though remember to do the same with the camshaft.
