Im trying to figure out if my accord is f22b1 or f22b2 is the only difference vtec or non-vtec??

 

If you have a factory USDM 94-97 Accord if it has VTEC it is the B1 engine. Valve covers of VTEC engines usually have 'VTEC' cast into the cover.
Valve covers are NOT interchangeable, so a B2 cannot have a B1 valve cover.

 

I apologize for for hijacking here but I wondering how to find out the engine code for our 2001 accord v-tech 4cyl .
Thanks!

 

Pretty simple.
Look at the water outlet that is facing the radiator(not the thermostat housing), now look under it.
On the engine block there will be a raised embossed casting. It will be F23A#. If the block is heavily corroded you may need some scotch brite pad clean/clear it to read the casting.

Google image it if you are still unsure.

 

Thanks mike thats what i thought just needed to make sure its the B1

 

Thanks M.M. I'll check it tomorrow.
