I was putting the cover back on the oil filter canister and one of the nuts did not want to tighten down to the 25 NM specified, it was tight but it kept turning. Started the car, and the it took about 5 sec for the oil pressure to peg. no leaks. drove it around 1/2 a block before i heard it "blow". Oil pressure went to zero. Limped the other half a block home, popped the hood, and had oil everywhere, none leaking around the pan, but clearly the cover on the filter canister is what blew. The bolt that wouldnt tighten down had metal down inside its threads, as if it had stripped out all threads down inside the hole. There were little metal shaving from the hole threads everywhere and all the oil had drained out. it seems like the bolt it will thread back inside the hole, if i can get the the nut off. what should I do to fix this and do you think there was any serious damage? It smelled a little funny when i got her home...
