SOLD - 1985 F350 Crew Cab 4x4 C6 6.9L - $1500
SOLD - 1500 for the whole truck, comes with all the parts I have in the garage (enough to fill the bed, and then some).
HAS LOW OIL PRESSURE AT IDLE (see post in 6.9/7.3 section). Price may go up if I fix this problem (will be changin out oil...
Yeah, I heard that too, but I don't like the idea of trying to fit the end back on underneath there.
I may try removing the manifold and PS pump this time around.
I really wish I would have had the mechanical gauge on the truck prior to having the problem, then at least I would know what...
I am not sure which is the correct terminology, but the part I changed is to the left of the center hole in both pictures, missing in the top pic, present in the bottom pic.
It was very simple to remove and reinstall, there are only 3 parts: a spring which fits in the hole first, the wafer...
Well, so much for that. I put the spring/wafer/washer into the oil cooler on my truck and made sure I peened the aluminum so that it would never come out.
Start truck up and it has 25 psi cold, and quickly drops to around 3 or so PSI.
Dropped oil again and can see bearing material in it...
Interesting Finding
So, first I changed oil and filter, and nothing changed.
Next, I inspected the oil cooler that I took off of the truck, and immediately thought something looked different. So I spun the oil filter back off on the truck.
Here is what I found:
This is the oil...
Thanks for all the replies, looks like I will just need to get messy and swap rear headers.
I will change the oil first, but I really don't believe that could be the cause either.
If anyone thinks of anything else... please post it up. I will get to work and let everyone know what I find...
As I wrote in the original post, as soon as the factory gauge showed low oil pressure I replaced it with a mechanical gauge and recorded the oil pressures above.
I guess to make it clearer, I am asking:
1. Has anyone ever had any experience where changing brands of oil caused the oil...
I know it was a long post, because I included a lot of detail...
Also, you can see in my original post that I still have the original oil cooler, and the one I put on was from a 1992 7.3 engine. So I have access to two oil coolers.
UPDATED W/ PICS! Very Low Oil Pressure after Changing Oil Cooler and Filter
Hey guys, My oil cooler sprung a pretty bad leak, so I pulled the entire cooler off of my 1992 7.3L Parts engine. I cleaned it up really good and replaced the O-Rings, and swapped out my leaky 1985 6.9L oil cooler for...
I could meet you Thursday Evening, say in Rosendale (outside of Fon Du Lac), at 6:00PM Central? It is a crossroads and there are a couple gas stations there.
It would be about 3 hours on my end, 2.5 hours on your end.
Let me know what you think.
I have family in town over the 4th, but may be able to head down there on Monday (the 5th) morning, would his work? If we met in the middle somewhere, I could do it after work on Thursday too.
On the vacuum pump - no longer have it, sorry.
Thanks
Dan
