Can the upper timing belt covers on the SOHC 3.2L be removed seperatly without draining the coolant and such, as the shop manual says? When I bought my Trooper the owner said the belt was replaced about a year and a half ago when dealing with a blown head gasket. I noticed that the bolts on the passenger side are bare metal and the drivers side look OEM. I have seen YouTube videos of these engines running with the timing way off the mark on the cam sprockets, and I'm wondering if this might be why then engine feels "fflat". By that I mean it pulls good to about 3,200 to maybe 3,500 rpm and then the torque falls off. I've never really taken it past 4,000 rpm on purpose, and don't really plan to. This was most obvious when driving up the 6% Sherwin Grade in California. Couldn't maintain 55 mph and had to drive it in 4th @ 3000 rpm and around 45-50. It runs fime around town and the CV joints are a more pressing problem for now. Can I pull those 2 top covers separately to check the marks? Almost looks like the are bolted to the bottom cover under the coolant hose. Google was of no help and the shop manual doesn't specify.
