Oil Leak

[Rocket Man]

My 1999 Tahoe 5.7 V8 4X4 oil pan seal leaked too. I ended up buying some really thick gasket material and made one myself (after a few failures with the OEM gaskets). I put two washers on each bolt, a little extra torgue helps a lot, and a light coating of RTV to make sure it stopped leaking. After that I did't have any trouble with it.

What I think must of happened was this...My truck was from Canada and the oil pan had a heating pad on the bottom of it (it had an electrical cord that you plugged into a wall socket and everything). I'm not sure if the pan came that way or it was somehow welded on. It was a novelty as everyone that saw the 3 prong plug always asked what it was for. And laughed because "Who needs to warm their oil in Hawaii? But the pan leaked, even after several OEM gaskets, so I took matters into my own hands (and using my limited skills coupled with my unlimited knowledge). Viola! The gasket was the thickest I could buy, around 3/16", if I remember correctly. It did effect the reading on the dipstick though. It always read a little low, so I would put in an extra quart so the suction port would always be submerged in oil. Better a little too much than not enough...

The 5.8 was manufactured ever Friday evening after the engine assembly guy screwed up boring the cylinder walls and had to rebore them wider. It's very rare because they only made 50 per year.

I thought that 5.8 was the one they made off that ultra rare early LS block with the 4.8/5.3/6.0 cast into it, because it's capable to be built any displacement? Anyone seen one of these in person and know what vehicle it was originally in?
