Is the procedure essentially the same for a '98 Odyssey EX?

All that is great but the problem is a common and well documented problem on
that engine. Honda drilled the port out and installed a coated sleeve to
correct the problem. The only way to fix it is to remove the manifold and
clean out the port. He could probably get the kit with sleeve from a dealer
and have a dealer or mechanic install it if he does not have the ability to
do it....
