redsupratt6spd Posted February 19, 2012 Share Posted February 19, 2012 I am removing the pcv valves to weld on 12 an fittings. Cam cover with oil cap valve just pulled straight out but the other side had to be cut flush,is this all you do or can it be fully removed so the opening is bigger? thanks jay Quote Link to comment Share on other sites More sharing options...

mixad Posted February 20, 2012 Share Posted February 20, 2012 Drill them so they are as big as the AN12 inside diameter. Then remove baffles and thoroughly clean them. You don't want metal chips inside the camcovers... Quote Link to comment Share on other sites More sharing options...

redsupratt6spd Posted February 22, 2012 Author Share Posted February 22, 2012 Ive always manged to pull em out, no drilling means no swarf !!! yeah don't fancy drilling due to not knowing if all the swarf is out not sure if the old fitting is pressed into the cover or not. I'll take a pic and post it up and i'll check the inside diameter against the weld on fitting. Quote Link to comment Share on other sites More sharing options...

If you drill it you need to also drill the baffles out and then refit them after you have drilled and tapped the holes to use bolts, this is so you can clean them properly Quote Link to comment Share on other sites More sharing options...
