pontiacfreak142 Posted June 14, 2011 Report Share Posted June 14, 2011 long story short, found out the motor in the mustang had a cylinder with low compression and needed new rings all the way around. tore motor apart, all new bearing in bottom end, had valve spring seats machine due to bad wear, new valve springs, all new piston rings. dad fired up the motor while i was at work. said it ran fine (in park) for a few minutes, made a quick ticking/tapping sound then the motor locked while he was messing with the timing i guess. it wont turn over at all, even tried with a pry bar and wouldnt budge more than an inch at best. is the motor toast?

Patterson Posted June 14, 2011 Report Share Posted June 14, 2011 What's the oil look like? Quote Link to comment Share on other sites More sharing options...
pontiacfreak142 Posted June 14, 2011 Author Report Share Posted June 14, 2011 he said from what he could tell, there wasnt anything in it, but the motor was still in the car so he couldnt just look in the pan yet. Doing that tonight. is it possible for a motor to just lock up that quick and not be a main bearing? Quote Link to comment Share on other sites More sharing options...
rl Posted June 14, 2011 Report Share Posted June 14, 2011 Sounds almost like a washer or something was dropped in the intake. Pull the plugs and see. Quote Link to comment Share on other sites More sharing options...
86GT Posted June 14, 2011 Report Share Posted June 14, 2011 That's what I was about to say....did something make its way into the cylinder like a washer or small screw/bolt. Reason I say this bc the same thing happened to me last year, had a small allen headed screw come loose on my fuel rail and I didn't see it fall into the head when I pulled the intake. Made a loud ticking sound and I couldn't turn it over by hand. Quote Link to comment Share on other sites More sharing options...
