The only way to know for sure is to look. The change over date was OCTOBER 16th 2000. There are some engines built before that date with the PMRs' and some engines built after that date with the Forged rods. The ones before 10-16-2000 that have the pmrs' were test engines, and the ones with forged rods after 10-16-2000, were when they supposedly were running low on pmrs'. The inspection hole is just above the oil filter. It takes a special tool to get it out but you can do it with some 5/16 th square stock and a crescent wrench. I used one of my nail set tools as it had a 5/16th square end. The oil level is below the hole so it will not spill out. DI performance has instructions for where to locate the hole and shows what the different rods look like so you can compare. Hope this helps ya, Gene. :mafia
Sorry guys when I was reading the post the second page did not come up so I responded and when I hit post quick reply, the second page came up so I guess that I just gave ya'll some repeat info.By the way my 10-09-2000 build date engine has the forged rods, I checked to be sure. Gene :mafia
This question has been posed often the official cutoff date for forged rods was October 16, 2000. There were however engines built previously that had PMR's as these were test engines. When they made the switch they ran out of PMR's and had to use forged rods again after the 10/16/2000 cutoff date. So the only way to really know for sure is to pull the inspection plug. it is located just above and to the right of the oil filter. It takes a 5/16 plug tool, but you can use any piece of 5/16 square steel stock and then loosen it with a crescent wrench. The inspection hole is above the oil line so you will not spill any oil when you pull the plug. There are pictures of what to look for at DieselInnovations.com . This really is the only way to know for sure. Sorry for the long post, Gene. :mafia Sorry guys the second page did not come up again and I thought this was a new post asking the question. :sofa:
