Todd 13 Posted October 16, 2020 Gave my 351c a new water pump for incoming summer and used a zivor cast and its gets tiny small weeps coming out of bottom.first fitment I used aviatIon gasket sealant with gasket and couldn’t stop small weeps under driving temp no matter how much I did up bolts. second time I used water pump gasket maker with gasket and same result . Should I try different brand water pump maybe alloy type and maybe replace sandwich plate Share this post Link to post Share on other sites

Without seeing it in person, I can't be sure about that though. Found also be coming out of the tell-tale hole from the shaft seal.Sent from my CPH1920 using Tapatalk Share this post Link to post Share on other sites
Todd 13 Posted October 17, 2020 Thx for reply gerg yeah it looks pitted in some areas are the sandwich plate straight forward to fit its looks like two bolts on timing indicator and another bolt opposite side with two dowels.Is it just just three bolts and a gasket or is there something I have overlooked.Cheers Share this post Link to post Share on other sites

If you try and put the timing cover on without dropping the sump, the half-moon will likely push into the sump as you pop the cover back on.Sent from my CPH1920 using Tapatalk 1 bear351c reacted to this Share this post Link to post Share on other sites
