looking at buying a local 91 integra, everything is good except it needs valve seals. Is this something i can DIY or is this a pretty hefty procedure? thanks in advance for any info

 

if you have to ask there is a good chance it's over your skill level. valve seals are exactly what the sound like, small seals that sit on the valve right on top of the guide. however, it's the popular thing to say "car needs valve seals" when in fact it could be rings, guides or all 3
