If you have chuffing out your rocker cover , changing oil seals is not going to fix it, its caused by piston blow by. What engine and what are you doing to it?

You will be wasting your time putting the head back on if you have it off(it is possible to replace stem seals with head on) The reason you have the chuffing and oil coming out is due to piston blow by due to either bore wear or rings gone . Have a look down bore and see if there is a step above where top ring stops at top of bore when at tdc. If yes then its bore wear. If no then rings are supect, could be stuck in esp if running on veg oil or mix HTSH

Sounds like another 200tdi transplant candidate - I wouldnt bother beyond a HG job on a 2.5na.

Don't bother.
You won't find out anything you don't now already know.

Live with it or fit a 200 tdi!

See the thread above and try fitting a catch-tank in the engine breather.
