Title: TD5 Hairline Crack @ Engine Casing
Post by: landroverclan on April 06, 2007, 16:41:21: It's a 1999 model TD5.
Found that this is the source of the leak.
What was the cause of it, overtightening of the bolt ?
Can it be sealed off using what they called '2 tonne glue' ??
or can it be welded (alloy) ?
beside replacing the cover, what other possible options ??

Thanxs All !!

So that leaves Epoxy type glues/resins or a new part.

If you can get it clean then you might get away with glue, but for how long?

I can't recall what it's Called but it's an epoxy putty that sets very hard, will withstand high temerature fluctuations and can allegedly be drilled once set.

I drained the oil down, cleaned everything up as best I could with carb cleaner and pressed the putty in as hard as I could. Two years later it is still OK but of course it doesn't get wildly hot and it's in no way pressurised.
