I bought a 1995 F150 last May from some close friends of mine that are also car nuts like myself. I knew the engine had been sludged at one point( by her ex husband ) but they had taken it to a shop and had everything cleaned out. A new oil pump was also installed. That was about 5 years ago. The truck ran great, the oil looked good, and there were no odd noises or anything.
Then at the beginning of December as I was leaving from work the oil pump locked up and it twisted the pump shaft till it snapped. The 5.0 was toast. I decided that I would just buy a new long block.
When I pulled the pan off it was nice and clean inside but I noticed a chunk of junk in the oil pickup screen. The pump had been starved, heated up, then seized. I pulled the valve covers and everything was pretty clean.
Then I pulled the intake off and HOLY *&%*&$&&*&**&% Apparently the shop that cleaned everything out DIDN'T clean everything out.
THE BOTTOM OF THE INTAKE
THE LIFTER VALLEY. It was so thick that you can even see the lifter brackets. For fun I cleaned out the stuff and weighed it. In a small thin trash bag the crust and sludge weighed in at 5.5 pounds. LOL.
