STOP THE OIL LEAK
Stop my leak on my 1999 Chevy s10 4.3l. You need to trim the lip on the botton of the timmig cover before installing it so it will fit over the oil pan and use Gaket maker before putting it on.

Not bad, thought it would be pretty lousy quality but it held up ok and stopped leaks
The entire design is very stupid and GM went back to Aluminum housings after they stopped producing this design. But regardless, this replacement was not bad, came with the bolts, everything went in fine and stopped the oil leaks on the vehicle. I'm satisfied.

Product arrived VERY damaged and without gasket (would not recommend)
Bought the "new" option this king it was going to be a brand new timing chain cover, what I got had have been through at least 100k miles. The gasket is ancient, oil all over it due to a poor install. Missing sever key bolts. It arrived in an unusable state. The plastic is broken as well. How is this new? Watch the video and tell me how this is new.
