problem #2

F-150 XLT Lariat 4x2 5.0L V8

This family of F-150's had cork oil pan gaskets, and if you're still driving it around now in 2015 it's probably leaking. You can replace it with a rubber oil pan gasket to solve the problem, and while the gasket is under $100, the labor to replace it can be anywhere from $600-800 because you need to lift the engine up and remove/replace all of the old rusted bolts.

Since the truck is worth $500-$1500, it's not worth the cost to replace the gasket. I ended up adding some RTV sealant around the gasket to try and hold back the leak which helped a little bit for $30, but it doesn't solve the problem. There is a risk of fire, but mainly it just stains my driveway. Luckily it doesn't leak enough for me to need to add oil to the engine during regular use.

Major oil leak coming from oil pan. Did cause a fire at one point but was put out before serious damage could be done. It amazes me that an oil leak could be this large and I later found out that oil was leaking from nearly everywhere possible.
