If this is a repost, then my regards. Well the other day I thought a exhaust gasket had gone out in my recent cheap buy of a 2000 Chevy Cavalier. I want to flip the car and make a little bit of money and no ones going to buy a car for a decent price sounds like open header. So I found that the flex type pipe from the down pipe was leaking. I paid for the decent replacement and had it take care of. Only to find that I had jumped ship too fast and that wasn't my exact problem. Turn of events, some one replaced the head on the car and didn't get the exact replacement of its year. It came off a older version, that had a EGR Valve and newer generations don't I guess? Now the head does work well and the manifolds and everything else seems to bolt up well. Instead of making a nice EGR block plate, who ever did this great amount of work took cardboard and JB Welded it over the exhaust whole. It late wore out and started to flap and make a horrible noise. I took me an hour to wrestle the plastic intake out of the way and another hour or more to scrape all the old JB weld off. I'm afraid to find anything else. So far this is my worst. Whats yours? Heres the new block plate.
