Car Forum / Dodge / Dodge Trucks / May 20075.2L to a 5.9L
Started up my '98 Durango 4x4 today to hear it knocking. Gets much louder at about 2000 RPM. The wife ran it out of oil a couple of days ago. Anyway, I was curious if anyone had any thoughts or experience with replacing my 5.2L with a new or rebuilt 5.9L. They seem to be running about the same price and I know Durangos came with both. Will I need to do anything else besides just swapping out motors? Use the original computer, but use the 5.9 injectors. Remember the 5.2 was internally balanced and the 5.9 is externally balanced, so you cannot mix either the harmonic balancer nor the flywheel/flexplate.

Thanks so much for the heads up and your help. > Use the original computer, but use the 5.9 injectors.

The wife ran it out of oil a couple of days ago. Think a bearing was spun? That should be cheaper to fix than a new engine but the 5.9L will perform FAR better and might even get slightly better mpg. miles, You are exactly correct about the performance and economy. When I changed from 5.2 to a 5.9 I saw 2mpg better economy. That extra stroke is worth 40 ft/lbs across the entire speed range at virtually no extra cost.

I'm still sizing up my options. >> Started up my '98 Durango 4x4 today to hear it knocking. Gets much >> louder at about 2000 RPM.

Even checked the coolant for mixing. It doesn't smoke a puff either. Still scratching my head over that. I'm sure the repair will reveal alot. Admittedly, I should have been keeping a closer eye on the levels though. >>>> Anyway, I was curious if anyone had any thoughts or experience with >>>> replacing my 5.2L with a new or rebuilt 5.9L.
