Tappet chest breather.

Post by **wanderinstar** » Fri Jan 02, 2009 12:15 pm

On my present engine and the one I am rebuilding the breathers from the tappet chest have been cut in half and rewelded back together. I presume this was to remove whatever was inside them. At the moment my old engine is blowing quite a bit of oil out of this breather, is there anything I can put back in it to slow this down. Had thought of steel wool but dont want bits dropping out of the bottom and getting into oil. Any suggestions?

Copper pan scrubbers from Poundland Ian ! Don't know why the tappet chest breather should be cut/welded - that's normal enough on the timing case to make room for the fan - but plenty of room at the side.

The top has been cut off both of them and than rewelded back on. Only thing I can think is to remove whatever was in them to start with. Was wondering if it would be possible to stuff something through the 1/2" hole in the top to save cutting and welding again.

Strange - well - you can probably stuff in the copper scrubbers - and at least they won't rot! If it's smoking/fuming badly - then you need to connect it directly to the carb - or directly into the inlet manifold via a 1/8" diam restrictor. I did this very successfully with a smokey Mini engine - no more nasty smell and no more oil leaks either! It upset the idle slightly - but i was able to tune it in ok.
