Eagle_Adam Posted May 15, 2013 Report Share Posted May 15, 2013 you should add the details of what you have done so far to try and stop it ;) Quote Link to comment

TENDRIL Posted May 15, 2013 Report Share Posted May 15, 2013 it sounds like the starters return mech. isnt working fast enough.... Quote Link to comment
bananahamuck Posted May 15, 2013 Report Share Posted May 15, 2013 have someone spin motor by hand while you look at teeth on flywheel .. Do you have the plate between the engine and trans in place? By the way your engine once running ,, runs like a frickin top!! :thumbup: Quote Link to comment
datzenmike Posted May 16, 2013 Report Share Posted May 16, 2013 Has this ever worked properly and is just now starting to do this???? Has the motor, transmission or flywheel been out lately? Quote Link to comment
jastrunk97 Posted May 16, 2013 Author Report Share Posted May 16, 2013 It only makes the noise while I'm turning the key, once it starts it sounds great! And its always done it. I pulled the motor out last year and when I put it back in and all together it sounded fine, then it got worse and worse, It just recently got really bad. Quote Link to comment
datzenmike Posted May 16, 2013 Report Share Posted May 16, 2013 Did you have the flywheel off? Check that the transmission to block mounting bolts are tight. Quote Link to comment
Toyanvil Posted May 16, 2013 Report Share Posted May 16, 2013 Did you have the flywheel off? Check that the transmission to block mounting bolts are tight. +1 sounds like your bellhousing bolts are loose. If it is an auto trans check the flex plate bolts. Quote Link to comment
datzenmike Posted May 16, 2013 Report Share Posted May 16, 2013 My truck makes a weird grinding noise when starting. . Counting the brake lines I don't see clutch line. You can access the torque converter bolts but not the flex plate to crank bolts. Quote Link to comment
jastrunk97 Posted May 16, 2013 Author Report Share Posted May 16, 2013 I am going to put the starter back in tonight or tomorrow, pull the plugs to see if it makes the noise under non compression strokes. Did you have the flywheel off? Check that the transmission to block mounting bolts are tight. I never had the flex plate off and il check them when im home tonight. . Counting the brake lines I don't see clutch line. You can access the torque converter bolts but not the flex plate to crank bolts. Why would the torque converter cause this noise if they were loose?

izzo Posted May 16, 2013 Report Share Posted May 16, 2013 Sometimes they come loose. First, check your bell housing bolts. Make sure they are tight. Make sure you have the little plate between the trans and the block. Second, pull your starter out. Look at the teeth on the flex plate, and the starter. See if those are rubbing together or getting smashed together from the starter not releasing. Grab the flex plate and see if it moves back and forth. It should flex a little but not really flop around or make a clank noise when you move it back / forth (dont try and spin it, move it from front to back, wiggle it good make sure the flex plate bolts are not loose) Third, Jack your car up and secure it with jack stands. Pull the trans access cover off. I use a socket on the crank pulley bolt to spin the motor around slowly. Your fan might hit the socket but its fine... Anyways, spin the motor around and check to make sure the four bolts that secure the flex plate to the torque converter and nice and snug. Its hard to get an actual reading with a torque wrench, but what I did was use a stubby wrench and a 5lb sledge. I didn't go to tight, but I made sure they wouldn't come out :lol: Do these, report back. Quote Link to comment
izzo Posted May 16, 2013 Report Share Posted May 16, 2013 I had a nasty noise coming from my automatic. It was cuz the bottom bell housing bolts were MIA.... put new ones in, and was good to go! Quote Link to comment
jastrunk97 Posted May 17, 2013 Author Report Share Posted May 17, 2013 All the bolts are there and nothing is loose from what i can tell...might try out some different starters i have to see if it does anything (i have 6 starters...) Quote Link to comment
datzenmike Posted May 17, 2013 Report Share Posted May 17, 2013 Yes if you have a spare this eliminates that as the cause. While it is off look at the starter ring, it's on the outer edge of the flex plate. Try moving the flex plate and see if loose. Quote Link to comment
Rollover_Red Posted May 17, 2013 Report Share Posted May 17, 2013 i had this similar problem in my 510, my starter started going out and the sylinoid wasn't reaching proper length and started grinding against my flywheel. still started the car, but made a horrible noise every time. check your starter as well. 1 Quote Link to comment
