Car went down for about 6 weeks or so due to the trans going out, I tore the trans out got it fixed and then threw it back in. Got everything on the engine all buttoned up. Go to start the car and I hear this god awful noise so I shut it down real quick, get out of the car to look at the engine and didn't see anything out of the ordinary. So I start it again and sounds the same. Had my buddy this time start it so I could have my ear near the motor, it sounded like major valve slap kinda like an old diesel motor.
Only thing I had done to the motor were put new spark plugs in. When doing the trans we put a wrench onto the alternator bolt to turn the pulleys in order to get the splines on the trans lined up.
There also was a ground that was not hooked up to anything, it was an engine ground so I fixed that. Nothing crazy done to it and it sounds like ass and won't last long.
There was also a strong smell of fuel in the air.
Anyone have any ideas?
Thanks in advance
