Road trip blues

[Mike Hohnstein]

Keep in mind Kerry has an aftermarket turbo conversion applied to a NA 210 hp.
I suspect there is a fair bit of "custom" work done to the coach that
complicates maintenance issues when they arise.
Fresh properly adjusted belts,new hoses, proper cooling system ph level and a
clean fuel system are the best ways to stay off the side of the road.

Aside from belts and hoses, what else can I do as far as preventive
maintenance to make sure I dont end up on the side of the road....I can't
imagine going through what Kerry is now....what else should I be checking under
this bus?

Crossover pipe takes the exhaust from one manifold over to join up with the

both power the
turbo. It broke on the left side right near the intake for the air cleaner
which is in front of
the left wheel. I had to drive it a couple of miles to an exit and it was
spewing huge clouds
of black smoke because the turbo was barely turning since the exhaust from
both sides
was following the path of least resistance which was out of the broken pipe
instead of thru
the turbo. Without the turbo'd air it was way overfueled for the amount of air
it was
getting.
By the way, it is probably worth noting that the crossover pipe had probably
cracked
before it broke resulting in less air and I had noticed the egt's were running
about 150
degrees hotter than normal. They could get over 1200 degrees if I wasn't
careful on a
steep hill. This tells me a richer or overfueled engine could have dangerous
EGT levels
pretty easily.
