    Who has lost DD15 because of sudden oil pressure drop to 0 psi? Since 2015 or 2016 DD has installed plastic suction manifolds that has two glued caps. Looks like Chinese(Chinatown don't get mad on me) or Third Reich times leftover glue was used and caps are coming out. What you can you do to avoid engine loss. Connect DL and go to Engine Protections. Enable Engine shutdown at low oil pressure. Parts #' A4721805951 and A4721806551 are plastic manifolds. In general always keep attention on oil pressure at idle. If you see pressure is going up and down 2-3 psi open the oil pan.

    one I took out had no *Made in Canada* written on part. it was original part. I have posted pictures of new updated manifold A4721806551 . its made in Canada. They both have same glued cap.

    Has any aftermarket company designed and built a better manifold?
