Re: 727 Leaking Fluid like it was made in Great Britain

Jason, Please elaborate on what you mean by rowel pin drifting?
Wrong size dowel Pin reinstalled? Someone filled and redrilled?
the reason I'm asking is to know what to look for as I rebuild my 318

I finally took an empty trans case and dial indicated the centerline of the crank against center of trans. Low and behold a dowl pin had drifted in in the block allowing the trans to shift out of alignment you are allowd 7 thou of miss allignment and the seal is supposed to seal it but without the dowls to hold it. Every time rhe thing would leak even tried a couple different trannys same thing. Then i fixed the dowl and as yiu say beat on the car merciloisly till the 410 gears surrendered boy they heard them a county block away when they steped out. O well. Next project. Jason
