Oil Leak Front Cover on a 6.7L Power Stroke
- Last Modified : Mar 30, 2021
Came across a few of these suckers... unidentified oil leak coming from the front cover of a 6.7L PowerStroke in a 2013. Covers front of oil pan with wet oil. Hard to pinpoint the location. Using florescent oil dyes, we made an assumption that it could be the front main seal. We started a tear down to determine the root cause and devise an approach to repair it.
The process of removal of all accessory drive components is somewhat of a hassle. I wrote an article covering the replacement of the water pump. Please follow those directions until step 8. Upon removing the cooling fan drive assembly, we located the source of the oil leak to be the vacuum pump seal. While attempting to replace the seal, we noticed the bolts were loose causing the leak - we replaced the seal anyway.
