So I believe their is stats in them.. Cause at idle it will start to **** out the port side hose then after 30-40 sec the starboard side starts pissing... As for the plate being 1 peice or 2 peice not sure.. Everything I used to do the swap with was everything that came on that motor so I would imagine it would be the right one.... All I did was bolt everything to an older style mid shaft... So do ou guys still think it has someting to do with the poppet valve....
