2003 Deville Motor Toast
My 2003 Deville with 160,000 plus has given up the ghost. To make a long story short what started out as a multiple misfire on cylinder 6, has ended up as a broken exhaust valve or a broken ring etc, no compression on that cylinder. Started out changing plugs, boots, coil pack and finally injectors in an attempt to fix the problem but car ran progressively worse until it finally lost all compression in that cylinder. Pulled valve cover but did not see anything obviously broken in valve train. I have ordered a used engine with 66,000, miles and will have the shop install this weekend. Is there anything that we need to look out for during the swap? Or is there anything in particular in replacing the Northstar that anybody has had experience with that would be helpful. The shop has had experience in dropping engines in front wheel drives but has never done a Northstar. Any advice would be appreciated.
