With all the polls and recent HG implosions I decided to do the coolant service and replace the PHH. Our 80 is the main mall vessel for my 's When I bought the 80 last year I ordered tune up parts from CDan, plugs, wires, gaskets, etc. I read the write up on here, printed the one from Christo's site, bought some new hoses, etc. I was ready. After finally getting the old one cut off(major PITA), I moved on to trying to loosen the lower bracket bolt. I don't know how Powderpig/Robbie can do it w/out pulling the valve cover, I even tried welding a piece of roundstock to a box end of a cheapie wrench to get it to fit, no dice. My gear drive wrenches wouldn't work either, apparently I could not get >5 degrees of movement in the tight spot. So, valve cover removal time. Got the bolts out, tried to see if I could rotate the valve cover out w/out pulling the throttle body and of course it won't work. Just for grins I decided to see if I had a throttle body gasket in my box-o-goodies from last year. No dice. So, the cruiser is down until the gasket comes in to my local dealer on Tuesday. The upside is, I'll now adjust the valves, clean the throttle body, do the tune up, and re-RTV the half moon pieces on the front of the head(they are leaking). Hopefully no more leaks and major PM for a while. BTW, red coolant looked good, no sediment so far ~74K miles.
