take that chrome timing cover off, clean it real good, check for any burs were it seals, straighten out any bad spots, shine it up nice, then take it over to a nice solid bench, and with a big hammer smash the snot out of it so you will never be tempted to use it again, then take it outside, and throw that thing as far away from you as you can... :shock:
same goes for chrome oil pans....and chrome transmission pans, chrome rear end covers... always leak, everyone ive ever seen anyways....
Get a oem cover or a nice aluminum cover...
