thats what u are meant to do (drill it anyway u will not knock it out lol) i did it at work with a hole cutter in the pillar drill as a drill bit that size is very expensive to use once

yeah just go easy and take your time should be ok as hole cutters come with a piliot drill in them just measure the breather hose adapter with a mic and get the same size cutter

not really how will that fit inside the guid tube on the inside on the rocker cover and if he dose it from the other side how is he going to know were the middle is! a hole cuter or the right size drill bit will be best lol but as i said a drill bit that big is expensive for one use

As said expensive if only doing one to buyt a suitable reduced shank bit.
Would only cost a few quid to get done at a engineering place, as they wil have this size or similar bits.
I use bits larger than this in the lathe, but these are 13 shakes reduced so would fit in a ordinary drill, I use blacksmiths drill bits up to 55mm.
If doing yourself just drill pilot dead centre(as best you can) then gradually open with sucessive larger drill bits to the max size you have ie 10mm or 13mm normally, then use rotary file or rasp to do last bit.

was the spec R kit installed correctly in the first place?! most breather kits you get told to the cam cover, and wasnt that hole actually put there so it could be tapped at a later date for breather kits?! end of the day its a breather hole already in the block going to the cam cover from factory?!

alls i know its a bad idea to breath frm there was told this years ago, i wont be breathing from there ever again, and my car wasntbreathing heavily either i just know all the oil went from engine into that container and it was installed properly
ill be using a wrc one next or a ggr

Why do GGR breathe from the crankcase, & not the cam cover?
As explained above, most of the pressure is created in the cylinder block by piston ring blow-by. If the engine is vented from the top, the rush of crankcase pressure to the top of the engine will prevent the oil fed to the cylinder head from draining back into the sump. Admittedly, the oil vapour is more dense in the bottom of the engine, this is why we have the oil / air separators.

yeah crank case is fine, but why when i had it in the head when i over revved it sucked the oil out and spat it in the catch tank, but when i blocked it off it didnt do it even after being over revved
you carnt install the thing wrong anyhow 1 under turbo, 1 to kidney box one cam cover into breather seperator and catch tank, ive always ran them on my cossies, but all did the same even on fresh engines after running

It Wasnt Me!
Dont bother putting it there..
breather from either side of block to catch can, return to sump so your canister doesnt fill up with all your oil, and one from top of breather to atmosphere...
oh but wait, all the top cars have it on the cam cover, so it must be right !!??

If the bottome end is breathing adequatly then there will be little pressure running through this anyway, to actually have oil blown up this pipe the level would need to cover the depth of the head to the pipe attachement imo.
As a rule you can't have enough breathing, just a pity the evacusump system is not popular here.

im not saying its the way u should do it im just saying its how most people do it and its what cosworth intended after all they raced with it like that mate! also most of the top cars on the scene have it like that i only said that as the other guys were saying its best not to do it this way
each to there own there is no right or wronge way
each to there own there is no right or wronge way
tbh i think its just a old thing on the rs500 touring cars, ist not needed
the way i said is perfectly addequate for any spec of engine possible
the wrc/grpa rally cars didnt use it..
but like you say, its up to the fella if he wants to, so be it
