In some serious trouble, it broke...

Joepro · 04-01-2014, 12:07 PM

Nothing yet, plugs look brand new, ndicating nothing, all injectors pluged in, and there was a sh#t tone of fuel pressure when I relased it. did a comression test for the hell of it, 210-215 accross the board...Im hoping my car is playing and april fool joke on me, but its not funny, at all. You wont really see a vibration in a video but after it is together I will be more than happy to.

I've got my fingers crossed you've just got something making contact and it's an easy fix. So far everything you've listed is pretty encouraging.

Joepro · 04-01-2014, 12:15 PM

yes but the whole engine, trans,exhaust the whole thingis vibrating vilolently....going back together after somelunch and ill take some videos, this is so depressing ill tel ya.

Chuck33079 · 04-01-2014, 12:17 PM

Drop the oil and check for metal?

Joepro · 04-01-2014, 12:55 PM

Ill do that....ugh

jwick · 04-01-2014, 01:19 PM

Other than the vibrating does it drive normal? Could it be you lost a portion of the friction plate on the clutch disc? I know you mention it didn't change much whether clutch was engaged or not but just trying to come up with something.

Mitco39 · 04-01-2014, 01:22 PM

And you say its just a vibration and not a clashing noise right? I know one dead cylinder could cause a pretty noticeable vibration, maybe try pulling plugs one at a time to see if there is a faulty spark plug, or possibly a faulty injector.

High and consistent compression means that your rods are fine, metal shavings should tell you if a lower bearing went out (although I would expect more noise out of it). Maybe something crazy went wrong with the flywheel? Although that crank angle sensor on the flywheel is very sensitive and if that was the case the car probably would not start.

Did you try reading codes just to see if Uprev can pull anything out that might not be throwing a code?

Also you said you have engine mounts, any chance one of them broke? One faulty engine mount would cause all sorts of issues.

phunk · 04-01-2014, 01:23 PM

severe engine component failure generally comes with a lot of noise, not just vibration. i see you have all aftermarket motor/trans mounts. make sure none of them came loose. Check your crank pulley is on straight and tight. Check coil wiring and try and determine that all 6 cylinders are firing

None of the things that have been posted here scream "blown motor".

1slow370 · 04-01-2014, 01:24 PM

did you disconnect and then re connect one plug at a time to try and locate if it is a single cylinder or if its random? when you disconnect each coil it should change how the engine runs, if you find one or two that when you disconnect them nothing happens you will have found the cylinder you are looking for, then just figure out whether it is spark or fuel. If you have cats it doesn't sound like a blown cat does it?

No kitty cats on the BP kit. The turbo is in the way

haha

It is hunting for a idle now and set a temporary dtc for p0507 idle high...runs no different that before, confirmed there is fuel pressure, and a lot of it. Im gonna go insane here ina quick minute.

Joepro · 04-01-2014, 01:43 PM

Yes, I pulled the coils one at a time, also swapped the plugs and coils sideto side, I ohms tested the injectors(not a great test I know) all around 12. I have the check plate off the bell housing and all looks ok to me.

Mitco39 · 04-01-2014, 01:48 PM

I would try sticking a jack under your engine and slightly trying to lift up on it and look for play at each of the engine mounts.

Seems like all the key 'something major is wrong with my engine' checks are coming up empty. Looking more like you are rubbing somewhere you just can't locate or a mount went out.
