Engine shut off loud rattle

[groeten]

Thanks everyone. It was the engine mounting bolds. 3 were just a little loose, but that was all it took to make a loud rattle. Good thing I investigated the noise, because one of the transmission bolts that mount to the frame was just about to fall out. Put locktite on it. Thanks everyone for your help. Now on to figure out my oil leak.

Told you that was what it was. YW Glad you found the other bolts loose and got that fixed as well.

I see loose engine bolts several times a year. Most of the time, the customer doesn’t even realize it. I remove bolts, clean them up, apply Loctite and torque.

I see them come in all the time with the engine so loose it looks like it could fall off any time. What do you torque them to?

I use a socket wrench and then apply a cheater pipe and use feel to tighten them. They are tighter than spec when I tighten engine bolts.

Does that mean if it's threaded all the way and a nut is installed and tightened, it's a screw?

The hex head bolts are actually hex head screws. Just using the correct terms. Its just that over the years people started calling them bolts. So many types of screws out there is probably they started this to cut on the confusion what someone wanted.

Oh well off to get a couple shots that the docs insists on me getting.

Could be a loose pully.

check for a loose blade or pulley.

Glad the poster found and corrected the problem before something serious happened.
One thing, a lot of you post to use loctite on screw threads. Good advice but please specify what kind of loctite.
There are many varieties for specific applications, but most common is the blue 242 which is for removable applications, red threadlocker that requires a torch heat to remove the fastener, and I also use bearing mount.
Google and learn.
