is the 2.3 a non-interference motor? I thought it was non-interference but I am not 100% sure. Help?
Just like the wife :roll:TROLLhattenschatten said:SAAB engines are 100% interferance type.
So which are in a 9-5 then?Cliche` said:The newer H-engines are interference type engines. But the older, as in 1980 and older, B-engines are not interference types.
Whether the pistons will smash into the bottom of the valves in the event of the timing belt/chain breaking......i believe. (feel free to correct if i'm wrong)SectorNine50 said:What are non-interference and interference engines?
That is correct. The Saab H engine was introduced with the C900 (B2XX series motors). They are all interference engines. So if timing is not set right, things will smash into each other.Kermit said:Whether the pistons will smash into the bottom of the valves in the event of the timing belt/chain breaking......i believe.

Running interference design allows you, amonst other things, to run a higher compression ratio, stronger piston design, larger squish area (as the piston is further up the bore), get better chamber filling, swirl and burn, better emissions etc. etc.SectorNine50 said:So what's the advantage of that then?
