I recently bought a 96 Rav 4, 80k miles from the original owner. The
timing belt has never been changed. I have changed a timing belt and
water pump and seals on a Honda Civic, Mazda truck and a Ford Ranger. That's
the extent of my experience.
I certainly didn't do them in a couple hours, but after enough
perseverance, I managed the repair. I am tempted to try this as the
Toyota stealer out here in Hawaii wants $1100 to change the
seals,water pump,timing belt,drive belts. And they are booked 1.5
months out! The other mechanic shops I know, I don't trust to truly
change out the cam and crank seals etc.
What kind of nightmare am I looking at? In the past, the worst part
of
the job was getting the crank bolt loose. But there are always other
land mines along the way!

thanks in advance
