You must be referring to the front balancer shaft oil seal recall. It only effected the first 8k or so preludes in 97. Mine is supposedly in the recally but I haven't got a notice. I'm going to ask the shop to install the retainer when I get my timing belt changed.<font face="Verdana, Arial" size="2">Originally posted by preludeprincess:

The balancer shafts are used to cancel out (equalize) vibrations due to a 4-banger's natural tendencies. The seal is necessary as the balancer shafts are bathed in oil. I believe the H22/H23 were the only engines to get these (F blocks too?). The B series don't have them from what I recall.<font face="Verdana, Arial" size="2">Originally posted by preludeprincess:
do you happen to know what does the balance shaft do? and why it needs to be sealed?</font>
have you seen what it looks like?? it looks pretty cool. When i had an oil change a few weeks ago, one of the guys had never seen one on any honda before. He said, and i quote "dem preludes must have that new honduh technology" haha<font face="Verdana, Arial" size="2">Originally posted by Gabe:
The balancer shafts are not the problem, it's the oil seal on the balancer shaft. Over time the front balancer shaft oil seal may back out of the oil pump. This will lead to a huge oil leak where the oil seal is and you will lose all of the oil in your engine. To prevent this Honda is installing a little "C" clip retainer in the shaft so that it cannot back out of the pump.
