Thread: Timing case oil leak

another possible is a floating crank shaft that has chewed/dropped a thrust washer- this allows the crank to push the seal causing the leak.

The camshaft oil seal can suddenly leak too, I did one last week where a recent belt change had been done.

Landrover says to only insert the wading plugs when wading, your new timing belt is probably coated in oil and this will eventually cause premature failure. where's the logic in leaving the wading plugs in, Regards Frank.

I assume one of those seals is leaking. Is there any other possible explanation for this oil?

thanks

The logic is in not needing to crawl under the car every weekend and not having to think about water and muck getting where it shouldnt.
Hasnt been a problem as I check them each oil change and to date there has been no leaks of any significance ( except this one which has been caught early by luck only). Of course I see that it would be an issue in the case of a serious seal failure. Perhaps I will check them more frequently in the future....

It would be wise to change your timing belt as it will contaminated with oil and could fail or slip which could lead to valves hitting pistons or worse.
Have never had a wading plug in my 300TDi's over the years and the other 300TDi's that I have worked on haven't either and not one of them had any crap or muck in the timing case area.
So you need to take Land Rovers directive that wading plugs should be installed ONLY while wading. By leaving the Wading plugs out as stated by Land Rover, it only takes a glance under the engine to see if you have a seal leaking, there is NO good reason for leaving them in, it defeats the purpose they were designed for, Regards Frank.

Yes the car is booked in to get sorted and the belt will be replaced if at all contaminated. And, yes I will take your advice and just use the plugs when needed in the future thanks-seems crap does not really get up there that easily.

I don't even own wading plugs. Have done plenty of river crossings, sand driving and mud and have never had a problem.
