Thread: TD5 suspected Rear Main Oil Seal leak

I imagine it was wet before the Provent install, i have a oil in the same area and have done sump gasket, silicone on the cam plugs and stripped bolt on the rotor filter, I still have to wash it and a run i'm crossing my fingers now.
I have a POS inspection camera using it i still could not determine if the rear main was sus.

Not running down from the rocker cover or the rear cam cover plug?

I have a slight weep from between the top of the head and the plate that is below the rocker cover (is it called the cam cover perhaps?), but AFAIK it's headbolts out to fix that. It's only a slight seeping weep, very little so not worried about it. The rocker cover and front round plastic disc have been replaced and aren't leaking. I didn't realise that there was a rear cam cover plug - is it accessible with the motor fitted in the vehicle to replace?

EDIT: just found ERR5369 Seal Camshaft Rear in Microcat.

Trying to think,havent looked at a TD5 for a while.
I cant remember.
A torch and mirror will help you see it.

Is this a common issue or is there something else in that area that could be the cause?

Hmmm!... I posted similarily in the recent past also fearing the worst and it was suggested that I check the fuel pressure regulator (i have a Td5) and yes it was the culprit - which reminds me... I have to post pics of the install

Scott quite likely the rear of the sump gasket.

I did flick my rear cam plug out with a small screwdriver, that's on a 15p not sure if the 10p use the same plug it's like a cup type welsh plug fitted ar#e about with bonded neoprene on the sealing area.
Kinchrome make a mirror with a light in it which has been handy on the TD5.
