another note on installing seals is to lube them with grease or dish soap. i prefer dish soap because it evaporates off. the soap or grease will allow the seals to glide along the mating surface without getting bound up or tearing. only intake seal leak i've had was the first time i installed the seals dry.

I'll go ahead and take a crack at it, already picked up the seals at HD and watched a couple youtubes
