I have a 1992 Volvo 740 NON TURBO wagon. It has 210,000 miles on it and
I keep
it in great shape. The timing belt was last changed about twenty
thousand miles
ago.
However today the timing belt broke as my wife was going about thirty
miles an
hour. Everything just stopped and she was left at a dead stop
in the middle of
an intersection.
Before I listen to what the mechanic has to say I'd like to know if my
1992
Volvo 740 non turbo wagon has a *non interference* engine. It's my
understanding
that if it *-does-* no damage has been done to the
engine.
I'd read on the internet that 1992 was the last year Volvo made non
interference
engines. I'm hoping beyond hope that's accurate.
Any help would be greatly appreciated.
Thanks.

It depends on what engine is in it. The 8 valve engine is
non-interference, though the clearance is much tighter than the turbo
motor and there is some chance of contact if there is a lot of carbon
buildup. The 16 valve engine is interference and major damage is nearly
certain. IIRC both were available that year.

I'll defer to Mr. Sweet to correct me but I think you have it backwards
in that it may have been the last year for the "interference" engine
(B234F).
Thanks to all this group for the always helpful information,

The B21, B23, and B230 are non-interference. The B234 is interference,
as are the "whiteblock" engines used in the later cars. A good rule of
thumb is that if it has more than one camshaft, it's an interference engine.
