A pretty severe failure on an interference engine tho. Keepers, nuts and springs can all be replaced in an afternoon with the head and cam in place. |
I do not know what you are talking about...
I am saying that with an engine which has billions of rotations on it... if you have the valve train down to where you can replace the valve spring seals it makes no sense ( given how little they cost ) to put the old springs, the old valve caps and lock nut, back in putting it back together.... penny wise and pound foolish...
but not against any laws...
