406 sedan rocker cover oil leak problem

Easiest way is to cast a silicone gasket in situ.

Clean the rocker cover sealing face of all oil using petrol or other solvent. Put a film of oil on the mating face. Use a reputable (e.g. hermatite orange in UK) silicone liquid gasket compound and place a layer on the rocker box cover. Fit the cover enough to locate it but don't tighten it. Allow the gasket to cure. Lift off the cover to inspect the surface, filling in any gaps. Fit the cover as normal.

Thanks Bob, I'll pass on the info.

Is it possible to see oil trails from the rocker cover or is there a general film over the whole area. I ask because I have, over the years, had a number of oil leaks in different cars that gave every impression that it must be from the rocker box but, in every case, turned out to be the oil pressure switch leaking.

Even the filler cap can cause a leak not fitting

Thanks for replying tinkerer,

Well it's going back in for it's third attempt at fixing this. (This time with Bobs instructions) There is a trail coming from the rocker cover (Between the first and second attempt at fixing this the trail moved). Before the first attempt it was not easily visbile until the engine was steam cleaned,

Thanks Chris, The filler cap has been checked and it's sealing properly.

Ah, well, If there's a trail then that pretty well clinches it. Good luck, let us know how it works out.

so its him thats leaveing all the oil on the roads lol lol

I'm trying to stop my own little BP thing from happening. LOL!
