AP1 Retainers Suck

June 14, 2010 by Aaron in Daily Happenings, S2000 #2

While doing a valve adjustment on our S2000 #2 demo car we found a cracked intake valve retainer on cylinder 4. These AP1 retainers should’ve been changed to AP2 retainers as a preventative measure but not we have to go fishing for the piece that fell off. Now to swap out for another spare engine and tear this one down. Word of advice for AP1 S2000 owners, CHANGE YOUR RETAINERS! They’re probably already cracked of will crack soon.

This just give us excuses to buy more tools. Hopefully Mr. Snap-On tools tells us the valves aren’t bent.

No comment so far
