Thread: Flywheel drain hole

they're not fitted, and I dont reccomend fitting them unless wading, as if you start to develop a rear main leak, a gearbox input seal leak or TC seal failure as appropriate then it becomes immedieately obvious by way of the new oil drip marks on your driveway.

if you seal up the auto its not to bad but in a manual the oil contamination will quickly be the death bell for your clutch. Unless your planning on sumberging the floor pan of your vehicle or have extra openings on your bell housing then you can go without your fording plugs right up untill you get bogged or stop on the ford. Once you stop it fills with water/mud.

Up imside there is the cam belt and as said you should put the plug in when wading if you don't this happens inside the Timing cover (as us poms call it)



and your cambelt snaps , no a huge problem on a 200/300 TDi but will ruin your day and cause you to go no where. Need to replace a few pushrods and maybe a couple of tapets and the cambelt. I did it twice in my winch challnge truck

The main reason you don't leave the plug in is because you need to let out air pressure which may build up . On my winch truck i had a breather tapped into the timing cover which let it breath and left the plug in all the time. And only took it out now and again to check for oil leaks

I have fitted elbows to the 2 drain holes (flywheel housing and timing belt housing) on my 300Tdi disco. Clear plastic hose from each elbow runs up to an inline filter hich in the engine bay.

The clear plastic hose allows a visual inspection to detect any seal leakage. The cases can breathe and muddy water is kept out.
