Defender 90 TD5 2004 rocker gasket oil leak

Sambora8080 · Jul 11, 2014

Hi I seem to have a small oil leak coming from the rocker cover at the back of my engine bay. It runs all the way down and makes you think your diff pinion seal is leaking.

I have fitted a new gasket and applied a copper gasket silicone designed for engine use. I tightened bolts upto correct torque 10nm.

Although I have improved the leak significantly there is still just the tiniest of dribbles for some reason. I am at the stage now where I have said bugger it and tightened the bolts up a bit more. Surely it can only be a case of nipping it up just a bit tighter?

Is it definitely the rocker cover? Just stick some rtv on it if it is

Yeah definitely the rocker gasket at the back of the engine bay.

I did put some sealant on it too. Obviously it needs more. Will have to try and re use the new gasket as I'm not buying another!

What is rtv and where can you get it from easily?

Any motor factors or halfords will do it. Really its just good silicon sealant

Right I bought this stuff from halfords it was £5 for a small tube and it was copper silicone stuff. It said it was designed for high temperature uses such as engine. I only applied it to the engine side though I didn't think it would need it on the rocker cover itself. Maybe if I remove it again and silicone both sides all over.

I just didn't want to go overboard and end up with it in the engine

That's the stuff it was the best sealant halfords had on the shelf. Still weeping a tiny bit though
