Alright guys Im new here, and i have a problem. So i have a 1990 240sx SR blacktop swap, I decide to do an oil change, due to the fact that i needed to seal the oil pan anyway, I seal the pan and put new oil+filter in, start the car for about a minute then it killed itself, I get out only to find all my new oil spilled all under the car due to the oil filter popping off. bought more oil, tightened the filter down tight and tried to start again, didnt start but turned over like it wanted to, next thing i know my entire back hatch is smoky and i think that the trunk is on fire, i pop the lid and realize that a red wire that is connected to the negative battery terminal and grounded to the chasis is completly fried, Im now afraid to try anything and would greatly appreciate any info that could be given.

Probably have your positive battery cable shorted at or near starter.....

It's possible that you didnt use a thick enough ground cable and all that cranking on an under oiled engine burned it out. Some of the cheap cables aren't the gauge they say they are and most of the thickness is insulation.

Also there's a good chance you damaged your bearings with the oil out.

+1 for this, its a common problem.

And let me guess when you did the oil change, you didnt check to see if the old oil filter seal was still stuck to the engine, so you doubled up on the oil filter seal? Again also a common problem.

alright changed the cable to a thicker guage, car fired up fine, ran it at idle for a minute, ran fine, then revved to about 3000rpm a couple times, oil filter popped off again, The old seal is not there checked it the first time, i tightened the filter as tight as I could by hand. Now the new filter wont screw back on, but the old one still will, so Im assuming it screwed up my threads on the new filter

I also found that there is a small scratch on the block where the oil filter is attached, could this be my culprate? is this fixable?

make sure the filters have the same thread pitch.....hopefully they didnt give you the wrong filter and it got cross threaded....and as for your cable try putting one of these 12" before the positive terminal it will literally save your car from a major short or it catching on fire

ok, so now im all sorts of confused, the original filter i took off was an stp s6607 which i replaced with the puralator pureone filter, which fit fine, now after being popped off a couple times the puralator wont thread, not even a new one. but, the stp still threads fine. this makes no sense to me.

Wrong oil filter dude. Use the same model as your old one.

Went and bought the original stp filter, works fine now, after wasting 60 bucks on filters and oil i think imma give advanced auto a piece of my mind.
