So as the title says, my engine or what sounds to be my head, is making an awkward knocking noise. Or if it were to be described any other way I would say it sounds like chattering teeth. Now I thought, "Hey! it's coming from the head so why don't I go replace the head?" So as stupid as I was I go and throw away $300 on a rebuilt head, oil, antifreeze, gasket set and all the other misc. and now it's still making that noise. And the only hint on what the problem is would be the head; now that would either lead me to suspect it's a bad head or I'm just an idiot? Any suggestions would be very much appreciated. I have an 89' 240sx with the stock engine - and just saying, "Replace the engine." would be good enough for me but any other suggestions would also be welcomed.
Now as far as engine replacement I haven't done it before with any kind of car but I will be looking into doing my first engine swap myself - and I have been looking around the forums but really in the search when I look up engine swap all I really get is the sticky that's on this forum and even that can be a little confusing. (possibly because I'm not familiar with all the acronyms you guys have for some of the parts.) Maybe if you guys could link me to some good posts that would be helpful also, in the mean time I'll be checking wikipedia and the such and a little more on the forums. As for new engines I was checking out this site:
Japan Motor Import - JDM Parts and Engines but I wasn't sure how I can tell how any of these engines will fit my car - is it based off of the weight, or is based off of the type of engine. (I'm assuming any of the ones labeled S13 will fit in my car) but some of them are labeled with (90-93) at the end would that be the year of the car that engine came from? Yeah stupid question, but I am not really familiar with alot of this stuff.
