You didn't say how many miles are on these engines but if the mileage is high I would guess it's not inconceivable that overheated oil could've brought about the demise of aged oil seals. And yes, you have to disassemble the valves to replace the seals. Of course, once you've done that you'll probably want to install some new springs...and since the top end's open you could do a cam swap as well... ;^) Brad ----------------------------------------------------- To Unsubscribe please visit www.chevelles.net/list.html To start a new topic, send mail to: [EMAIL PROTECTED]
