Programming Remote Key
hello, I have a 93 honda accord, and wondered how hard and what special tools do i need to change spark plug seals? I have oil in three out of the four spark plug boot areas. and do i have to remove the valve cover to fix the seal problem chuck pro
You have to remove the valve cover, but that's pretty easy. The spark plug seals are kinda like part of the valve cover gasket, they fit around the sparkplug hole. A valvecover gasket 'set' often includes these, but check to make sure.
If it continues to leak, it may be from the lower seals. For these you have to remove all the rocker assemblies & camshaft bearing caps. That makes it a much bigger job than the valve cover gasket.
