I'm having some trouble on my recent engine rebuild. It was overheating so I troubleshooted and came to the conclusion that it was my headgasket. I tore it down and saw the head had some sort of black sticky stuff all inside the IM and the intake ports. So I sent it out to the shop to check for any signs of warpage and had it hot tanked. The hg was in pieces when the head came off, so that was the cause of overheating.
Ok, on assembly everything went well. The car started on the first try. There was a high pitch hum that was coming from the timing belt, but other than that it ran like new.
So the problems arise. When the car was cool it ran smooth and like a jet plane because of the hum. Now when it came up to temp. the sputtering began. I thought to myself the timing is off because it felt like the bottom end was really torque heavy. I took it apart and fixed the timing and loosened the belt a little because it has hella tight. The hum went away (belt was to tight) and it seamed like the sputtering had gone but it didn't.
Oh, by the way the engine is a b15b7.
Any suggestions on what it might be? It would be greatly appreciated.
