Bought a junker for cheap and saw the bubbles in the reservoir tank. It overheated 7 times in my care, and who knows how many before I bought it. I replaced the head gaskets, belt, some pulleys, tensioner etc. Timing was off by a tooth at first but managed to fix and started her up. Ran real good. Three fill ups of 87 octane. I noticed an intense shaking from 60 to 70 mph but figured It just needed the tires balanced. About 400 miles after up and running; I was doing 70 on the highway, about ten minutes after a fill up of 87, a knocking that was really loud all of the sudden developed. I pulled over and drove 5mph to the nearest gas station which was around 10 miles away. This was the coldest night it had been the far in the year as well. Definitely not what the car was used to. I thought it might just need some oil. I was wrong and ended up getting it towed to the parking spot in front of my house. Since that night, Ive been starting it once a week so that the car does not get ticketed to move it to the opposite side …(philadelphia). It doesn't feel like it has any loss of power, there're no lights on the dash, it seems like its normal besides the awful knocking. I really hope its not rod knock which I barely can even define. I hope the its the belt tensioner because Ive seen other with that problem. Maybe all the times it overheated and the coolant mixing with the oil did some unseen damage. Maybe theres no oil pressure. I have a stethoscope that I will be playing around with tomorrow so hopefully I can point out the noise. I uploaded a video on Youtube; its posted below.
Pleaae help me figure this out. Winter is here.
