Default Re: My chain is saggy

Do you have a torque wrench? If yes, torque the plug to 120 inch pounds. That should squash the crush washer (gasket) and seal the plug in the cylinder head. Are you using the kit supplied spark plug? Some aftermarket plugs such as Autolite, and some Champions don't use a gasket but rely on a tapered seat to seal. No matter, the plug needs to be tight. It's not a semi-truck lug nut so don't over tighten it but it has to be more than snug.
DO NOT use any thread sealer or thread locking compound. If anything a good anti-seize product is all that should ever go on spark plug threads.
