Sorry guys havnt been on here for quite a long time .. i have a problem ... my rover 3.5 engine is in a trike my prob is to do with crankcase pressure at present i have to pipes one coming of each rocker cover running down to a catch tank which has a filter on top when doing a longish journey i have slight weeping of oil coming from head gaskets .. could one off you please advise on best way to set this up .. i ve read few articles that say fit pcv valve to one rocker cover and take pipe from pcv to carb (i have old su s with k and n's and no where to take pipe too on carbs) and other rocker to put small filter on it .. hope this makes sense and someone can advise best way to sort this out thanks un advance paul...

Hi

Crankcase pressure isn't going to cause weeping at the head gaskets. That's going to be a head gasket issue.

Ok thanks read on a site not having pcv valve could cause this .. still want to fit pcv valve can someone suggest best way to fit with my above description thanks paul

Hi

Crankcase pressure may cause weeping at the rocker cover gaskets.

Does the engine have the small filter at the rear of the block on the left side when facing the front of the engine?

Oil weeping from head gaskets is a common problem in my experience because there's nothing to stop oil running across the deck from the valley side and out. I run a thin smear of sealant along the inner edge of the deck and head to stop it.

Its not a common problem. Its a problem if you use the wrong gasket on the wrong surface.
Elring or Cometic gaskets need a different surface smoothness compared with oridinairy gaskets which you only need to sand down the surface and fit and forget. I just use the composite gaskets Real Steel sells.

Well I only every fit Land Rover genuine parts, and I have seen this problem with both tin and composite gaskets......
