MG TD TF 1500 - uh oh. Is this backwards?

Is this front cam bearing in reversed? It has an oil return groove pointing out to the front of the engine. I can't find any info on this. Logic would dictate that it should drain back into the crankcase.
Thanks Sandy

It is correct! It sends oil to lubricate the timing chain. Make sure you have a spring in the tensioner plunger assembly, also there is a later oil thrower for the front of the crankshaft, it has a larger diameter. Abingdon Spares stocks them.
See my Abingdon Performance Facebook page.

Well Len, that is a relief. So we can finally move ahead here. I will check that tensioner again. It has been a while, but I remember unplugging an oil port in it's body. The spring is there.
The bearing is partially obstructing the oil port, just a slight bit. Should I drill this out to open it up fully?

Great post. This type of info really helps.

If anyone wants a tool to install the front bushing, I have one to loan out.
XPAG camshafts are my business!

The groove is NOT for sending oil to the timing chain - it is for oiling the bearing surfaces between the front of the camshaft, thrust plate and sprocket. The timing chain is oiled via a hole at the end of the chain tensioner.
(I would prefer to open the cambearing hole to match the hole in the block)

So Len, do these tools also remove the bearing? Is it worth to try to remove and re-position the cam bearing? Is it even possible to reuse once removed, or are they destroyed?
