Default Rant: Designers/crash engine 2.0/2.4

Actually, I know those engineers. Trust me, they didn't want a "crash" motor
any more than you do. They were forced into it by the EPA. Those neat little
valve clearance notches in the pistons proved to be a "reservoir" of
hydrocarbons that are 'hidden' and won't burn. I.e., smog. They had to go.

But they tried their best. There IS enough clearance so that a belt that has
jumped two teeth will NOT cause a crash. And even a one-tooth jump turns on
the Czech engine light so you know something's amiss. And they REALLY broke
their stones to get 100K belt life on the DOHC.

I just did a belt on mine - not a hard job at all. But don't even think
about it without the FSM and a torque wrench handy! I suggest replacing the
hydraulic tensioner also, and carefully checking (feeling for roughness) the
bearings in the tensioner and idler pullies.

PS-
If you've got Crane springs on a DOHC - a GREAT upgrade for RPM AND smoother
idle (!) - change belt at 60K.
