[Shop-talk] Volvo Engine Swap

[Steven Trovato]

In the initial post, he said his brother had the broken timing belt 
replaced but that "didn't do the trick."  I think from this we can 
conclude that either it is an interference engine and more damage was 
done, or someone made a stupid mistake.  With the belt replaced, I 
would do a compression or leakdown test.  I would also seek out 
expertise on that particular engine.  I would say that on many 
interference engines, bent valves is the worst outcome.  If there 
isn't a particular known greater risk with this motor, then 
replacing/rebuilding the head sounds like a reasonable move.  Of 
course with the head removed, the pistons can be checked for obvious 
damage.  At this point, you haven't invested anything except the 
labor removing the head.
