 Extra Help for mis fireing Ford
Alrighty i narrowed down where my miss is coming from however there seems to be oil collected up around the plug itself, now i hope this is just a burnt valve. however my fear is that the rings have collapsed around the piston letting the oil through. i know for a fact that the plug is firing i took it out and connected it to the wire laying on the block when i started the truck it seemed to be firing and seemed to have plenty of compression... any more help that could be given would be greatly appreciated |
