I recently replaced the 6.9 in my 83 F250. The truck ran ok when I bought it, but it smoked until it warmed up and had a high rpm miss. When warmed up, it ran a little over 40 psi oil pressure at normal driving rpm, and dropped to about 25 at idle. Shortly after I bought the truck, I picked up an 83 6.9 from a local shop that pulled it from a K5 Blazer. The guy was doing an LS swap. He said that it ran fine when it came in the shop, but he wasn’t really a diesel guy.
The motor sat in my garage for a year until I finally had time to pull the original motor and put in the new (to me) one. I had to swap the water pump, starter and accessories to complete it. It runs great, but has a bit more blowby than I’d hoped.
The old motor had the tach sender and the new one doesn’t. My question is - can I swap the IP housings to re gain the tach, or do I have to swap the entire pump?
Any advice would be greatly appreciated.
