Hi there
Just wondered if any knew anything about this. I have a p100 with an oil leak but the strange thing is it coming from the top of the rocker cover from a circular plate that does not seem to do anything (bar leak) I wondered what are theses called and can they be replaced or do i just get a new rocker cover altogether.

 

Is it a petrol or a diesel.

 

for the cost I would just buy another one ( sure mines had a little leak for the same place o and it will be the diesel one

 

i reckon 1800 diesel it has a spring and a diaphragm underneath it if your breathers are blocked it will leak oil replace the rocker cover it is not serviceable

 

Its a 1.8 td and i put lock tight on it last night no leaks now but thinking "shit breather pipes blocked" Where are the breather pipes on these?

 

I just noticed the other day there is no 1.8td engine listed in the sierra haynes manual ? Anyone any idea where id get a haynes manual for the 1.8td engine
