Vibrating like Hustly's favorite toy
Dear sirs,
I am running into an issue that has me scratching my head. My Miata is vibrating like Hustly's favorite toy, and even at idle, I'm getting some fairly gnarly vibration. It's impossible for me to take past, say, 4k rpm due simply to insane vibration. I've checked or am checking/will have checked the obvious stuff, so help me out with the non-obvious stuff to check out please! I've reverted to the stock flywheel (resurfaced) w/the FM clutch kit now, and am not sure where to start beyond that. |
Collapsed engine mount causing exhaust to rub?

Engine mount, or you lost a bolt(s) on the PPF.

I just went over to RHarris' place and he made a spacer so my header would stop hitting the subframe and now I'm sane again.

My exhaust is so hacked up at this point that it may be time just to bite the bullet and buy a Garrett turbo plus an Abe downpipe+exhaust. |
Make sure all the bolts on your power plant frame are torqued to 200ft lbs. Seriously, factory spec is liek 150lbs or soemthing.
Also make sure you are firing on all cylinders |

125ft lbs.
https://sites.google.com/a/philb.us/...torque-specifi to fix your fuel problem, pull your injector and hit it with a hammer. |
Jeebus cripes, ~100 ftlbs still seems like an awful lot as per that site, but I'll make sure they are all torqued down nicely when I get a chance to get back under it. Wow, that's some serious torque on those bolts.
Also, not a fuel injector problem after all. Injectors are in perfect shape, it was a problem with my injector wiring goddamnit so much. I've never had problems in my wiring before. |
Oh good god. I'm a ------- retard.
I forgot to final tighten the motor mounts down, 10 ftlbs ain't gonna hold ----. |
Torqued it all down to proper torque specs, time to see if it doesn't vibrate like a ----------er anymore.

"Diesel powered vibrator" is the only phrase that comes to mind of equivalent vibrating. |
Sounds like your balance shaft belt has broken.
. . . . . . . . . I keed. |
At least we know when the engines terrible harmonics kick in. 4000rpm apparently.
