Oil began leaking on the garage floor about 39,000 miles. After looking for the source of the leak, it was determined to be the crimps in oil lines that supply and return engine oil from the remote oil filter at the front of the vehicle. The crimps are made of the same alloy the line are made from and they are attached to rubber hosing to provide some flexibility in the line, but if you were to sum them up in one word it would be: CHEAP!

So in order to fix this issue I had my brother who works at a diesel truck repair shop, make some quality replacements out of Cooper compression fittings and some higher quality hose. The parts for the 4 hoses and fittings cost about $70. The construction of the hoses took less than an hour. The installation time was a little over 2 hours. This was done about 5 years ago, and to this day, this SUV no longer drips on the floor, or anywhere else she parks it.

This is just another example of GM squeezing it's suppliers to lower their costs and getting the crappiest quality to show for it. This problem began just a few months after the 3 yr / 36,000 mile warranty expired, but if nothing had been done about it, there would be one massive puddle in the garage.
