I just bought a 94 Blazer 4x4 Tahoe Lt Edition with a 4.3 Vortec from a friend. Like I do with most used cars I buy, I decided to do an oil change.
Now, when I did one on my Corsica, it couldn't have been more easy, especially for the first time doing one, as it was simply remove the 14mm plug, let drain, run fresh quart through while open, change filter, replace plug with new gasket, fill, check, fill if needed, then done.
However, I drop under the Blazer to see what socket I will need, and oddly, it doesn't have a nut end, but rather a ridge all the way straight accross the head. I didn't think much of it, as I was going out to get a new drain plug and gasket when I went out before finishing the change, so I grabbed my needle nose vise grips, and loosened the plug. Good time for a change too, as the oil looked thick black and nasty. However, and this is where the oddity part comes in, the drain plug did not come out all the way and looks to be something like a long bolt with a large head (on the outside, with the ridge) put into the oil pan, then a washer and nut put on the other side (yes, meaning it would have had to be done before the oil pan was put on). Needless to say, it is still hanging out of the oil pan, as I can't seem to get it out by means of unscrewing it, and I don't feel like cutting it and leaving metal in my oil pan.
Annyone had this problem or heard of it or anything?
