New to site, My95 cutlais has the 3.1 and I have not been able to find a front valve cover with the same numbers.It looks like 94 and 95 were different than all the others. Does anyone know who to ask to see if the others will work? Or were to purchase one? Mine has a crack in it at bolt hole and leaks oil onto the exhaust manifold.The numbers inside the cover are 10154767 and 10154765 I amm looking for the front [left] cover.
