OK so I knew it was a bad idea.
After removing, cleaning, painting and planning to drive the next day, I realised that some dufus at an unnamed autoparts store gave me the wrong gasket. So I called around and found another one (at 7:30 pm on sat night) much to my surprise. At around 9pm that same night I tried installing the 2nd gasket. WRONG GASKET AGAIN!.
At this point I decided to take one of the gaskets that was wrong and make a gasket. I had to drive the Suburban the next morning. (and I might have been a weeeee bit impatient)
After cutting and sealing I finally got it together. Then when I cranked it to move it out of the garage I noticed gas dripping from the fuel pump.
So much for driving it the next day.
So when I finally did drive it a few days ago on I24 into Nashville, it was no big surprise to see a small puddle of oil under my truck after it sat a while. My gasket held supurbly everywhere except..........the top.
So today I hope to get the "proper" gasket and rid myself of this oil leak once and for.....well..... a while anyway.
