1996 Pontiac Firebird Q&A

1996 Pontiac Firebird Question: is there an adjustment for valve lash.

I have a 1996 Firebird with 3800 SeriesII, no add ons. I have an extreme chatter, almost a rattle/ticking under the left bank valve cover. I've tried the oil additives to avoid opening up the top end.No help. Any advise? -
Answer 1
This engine is equipped with hydraulic valve lifters, there is no provision for adjustment. -
