Hello everyone

It’s come to as no surprise That my mini has sprung a leak 😩took a look and it seems to be coming from the timing chain cover area but where the leak is coming from there doesn’t seem to be any gasket or gap present as it seems to be one piece? Could it be coming from the hole that the bolt goes through for the cover or could there be a split in the metal?.

Kind regards Tom

There is a gasket there. Between the front plate and the block. But it is unlikely as there is no pressure there. But as it is a upward facing surface look above for leaks. Like the oil gallery plug or the head gasket.

Clean off as much of the dirty leaked oil as possible, WD40 is a good cleaner, then watch over the next few runs.

Thanks for the reply

I’ve done a check cleaned the oil away and it’s coming from the point under the bolt in the picture any idea what the gasket would be called for that area? Pretty unusual I’ve got to admit.

This, but you'll need timing cover gasket, crank pulley oil seal, crank pulley lock washer, cam pulley lock washer and anti freeze to go with it at the very minimum.

I recently found a leak on a morris minor that was coming from the head gasket via the oil feed hole so it appeared to be somewhere around the timing chain area or sump so as nicklouse says, be sure.

Could it be coming from the timing chain cover side via the bolt hole?
