Hi, my name is Nick McCullough on behalf of Expert Village. In these clips we're going
to talk about the proper way to remove and replace and engine valve cover that is cracked,
excessively worn, rusted out, or otherwise defective. In this clip, we're going to talk
about cleaning up the cylinder head mating service. As you can see if you look around,
you can see exactly where your gasket goes. And what we want to do is have it a nice fresh
surface for our gasket and new valve cover to mate too. This is the cheapest spray solvent
on the shelf. I recommend getting it from these guys right there. I've shopped around
and this is where its at. You don't particularly need to use engine degreaser or anything like
that. Pretty much what you're looking for is just a volatile spray solvent. You're going
to spray away from the engine. Just for posterities sake, you don't want to blast a bunch of this
goo down in to your engine. It does have a filter and the filter will pick it up, but
you don't want it floating around in there for the one trip it'll make anyway. We will
take and blast away. You're also going to want to use your shop rag. As you can see,
it's coming pretty clean. You don't want to use any kind of metal scrapping devises on
your cylinder head. Nine times our of ten these days, unless you have an older like
a vintage vehicle, the cylinder heads going to be aluminum. If you were to take a razor
blade and try to remove this stuff, unless you are extremely careful, you may scratch
the mating surface and cause an imperfection greater then your gaskets ability to seal.
It would result in a leak for you. You don't want that to happen so just use your cleaner
and a shop rag. If it's a cast iron cylinder head, feel free to go ahead and scrap away
on it. That stuff is generally tougher then the stainless they make a razor blade out
of. All right, there we go.
For you plug galleys, if your vehicle has them or not. This one does and see these holes
here, they're where the hood wires run in to the spark plugs and the top of the head.
Like I said, you don't want to spray this stuff directly in to your engine so just spray
it on your rag. Give it a good soaking down and wipe around the sealing surface. All of
this here does not does not get gasket on it; only right around there. You can actually
see the ring from where the gasket seats. It's not necessary to clean up any of the
other stuff. There'll be one for every cylinder your engine has. This is a four cylinder so
we got a fourth. Make sure you get them all. If you sure what size or how many cylinders
your engine has refer to the owners manual. It'll let you know.
