In regards to several posts, yes. I like RvB. And I did look at the diagram you posted, thank you. Sold the black one i had for 500 bucks. the white one I have, and the red one I have left are different wiring harnesses. The white one is an 87. The red is an 89. I have owned several supras, Yes. However, I am not a great mechanic. So I kinda more or less ditch the ones in the past when they start falling apart on me. I will refrain from making any more posts for a while, until I have substantial progress as to prevent any further annoyance towards any of you. I mean no disrespect towards any of you. you are all helpful, in your own little.........ways....<IJ> lol however, I am just not the sharpest tool in the shed.
Sorry.
But yes, it was knocking. I originally thought bearings went out for the simple, single fact that my younger brother who did this, knows a hell of a lot more about cars than I do, and said that's what it was. My Gf's grandfather however, is much more talented with motors, and feels it is a single bad rod. Pulling motor saturday, so I guess we will find out.
Again, sorry for the bothersome, ignorant posts....
