After a good going over of an engine i recently inherited, cleaning and replacing a few bits i have had to replace the exhaust valve as the old one was slightly warped.
But in my haste i threw out the old one as it was warped and completely covered in carbon build up. I then ordered a replacement but when it arrived i notcied the face of it is dished (concave). The old one appeared flat but could of course have appeared flat due to serious carbon build up but surely not to such an extent that it appeared flat? Or could it.
All parts suppliers seem to say sorry we only do the dished ones the flat ones aren't available anymore. So can anyone shed any light on this for me as i assume putting in a new dished one if the old one was indeed flat will screw the valve clearances/ Cubic capacity up big time to the point that the thing wouldn't even run.
