My 88 240 gently coasted to a halt recently and I discovered that the
timing belt had busted. No nasty crunchy noises were heard from the
dying engine. But I have been told that the engine is now beyond
economical repair. And yet I discover on other Volvo sites that this
may not be the case and some owners have even effected roadside
repairs! All opinions will be considered please.

I have an 88 240 which experienced the same unfortunate event. It did no
damage whatever to the engine, and I've been told that (at least for
this model) a broken timing belt will -never- cause damage to the valves
or head. I had my local shop replace the belt and it's been fine ever
since. I'd be very impressed by anyone who can effect a side-of-the-road
fix for this problem!

A side of the road repair could actually be easier than done in a garage
(with poor lighting, or with a trouble light for added light). The
sunlight can provide lots of illumination. The tools are not the issue.
The issue is enough light to see the timing mark on the crankshaft
"pulley". Just some tools - AND a nail to keep the belt tensioner in
place while putting the belt on ...

Naturally, I assume (in my climate) that the work at the side of the
road would be done when the temps are above +10C :-)

The last 240 timing belt replacement I did was out in my driveway using
basic hand tools. It could be done on the side of the road if I happened
to have a socket set in the car.

North American market 240s all have non-interference engines, so a
broken belt will cause no damage. The 16 valve motor used in a few of
the 740s is a different story.

I was afraid someone would suggest the timing belt "roadside repair" would
involve a handy pair of pantyhose ("tights" in the
UK).............................

This has been thoroughly examined over the years. I suppose the concern
comes from Gates saying the engine is interference
http://www.gates.com/part_locator/in...cation_id=3598 but probably
the top level expert to appear here (Paul Grimshaw, author of The Gothenburg
Bible) listed the clearances with all available cams; even with the hottest
cam available it is definitely non-interference. In addition, although
crashed engines are legion in alt.autos.honda (where the engines are
definitely interference) I have never seen a post that related a crashed B23
engine.

ISTR B200's (8 valve flat head, combustionchamber in piston design) are
interference

its a simple job as your engine hasn't the interference design .cost me
$100au dollars took very little time . the twin over head cam engine is
the problem one the 240 is easy .
