2004 Buick Rendezvous Question: How do I slide the engine forward to access spark plugs/wires behind engine?
The torque mounts on top; Remove bolts to engine side and rock the engine forward, then install a bolt in the hanger to hold it forward while accessing rear plugs. - ProfessorG
Even if you can rotate the engine a little and it is 'just a little',, it is not really a diy project! Strongly suggest having this done by a pro.....I think you may save money that way,,IMO... - pushrod
