So I started my truck this morning came back outside and there was at least 2 quarts of oil on the ground . It appears to be coming from the oil filter o-ring but I haven't done an oil change recently checked the filter and it is tight. I found a similar thread on the pressure valve located on the top of the housing and im just wondering before sitting in 12 degree weather is this a common problem?

 

I removed the filter and the o-ring is fine so I assume it is the valve???

 

I haven't heard of anybody having trouble in that area. Clean it up good and start it again to see more clearly where the oil is coming from. There is a seal under the pressure regulator cover.

 

New oil filter no leak. Dont see anything wrong with the old one but oh-well

 

How messy is the area? Could it be comeing from the turbo oil line?

 

sure you do not have two o rings up there?

Yeah only one o-ring. The area was extremely messy but all cleaned up and no leaks
