Doing a long list of repairs on my X5 4.8L V8 N62TU and I’m stuck on a number of issues that I can’t get past. Anyone in the Tacoma area that would be willing to lend a hand?

Here’s what I’m in the middle of:

Replacing valve stem seal: I’ve got the right side valve cover loose, but the spark plug tubes will NOT budge. I can’t get my hand inside to try to loosen them.

Valley pan transfer pipe: I’ve got the old pipe out and Trygstad my to install the URO collapsible pipe, but I can get the new rubber gasket to fully seat at the timing cover side. There’s still a small lip sticking out on the edge which prevents the new pipe from sliding in.

A/C belt: got the old one off, but can’t stretch the new one on. There’s a tension pulley in between the A/C pulley and the camshaft pulley, but there doesn’t appear to be a way to take the tension off.
