In Reply to: Ford 2.9L posted by flint hills willie on June 25, 2009 at 16:01:18:
I worked for a Ford dealer when the 2.9L was still being produced. The only car to ever have the 2.9L was the Merkur Scorpio. The 3.0L used in cars and Ranger is completely different. I have never heard of the warped cyl head deck or cracking heads on 2.9's. The 4.0L had enough problems with cracking heads early on that there was a recall to replace the heads. The head problems that 2.9's are known for is the exhaust valve seats will disintigrate and the engine will loose all compression on the affected cylinders. If it has clattering lifters, it needs cam bearings. Also, check the thrust main bearing by prying the crank forward and back. If it has excessive end play, it's a time bomb. Each connecting rod has it's own journal. When the thrust main gets loose, the crank walks back and forth and when it gets loose enough, the counter weights on the crank will hit the rods and break them.
