i messed my car up help me :(

[nazgul]

Ok so a few weeks ago i put on a friends donated tein s techs on my s13 coupe and then one day i tried jacking the car up from the crossmember and i guess i wasnt all the way under it (body of jack couldnt go further because of sway bar) the car was already a couple inches off the ground and the jack slipped and car dropped and the jack smashed the bottom of the oil pan (not near pickup). Well now the car has an insane vibrating coming from the dash/steering column i have replaced the motor mounts and transmission mount and checked for anything thats loose or could be touching the rack and nothing. Alsp i replaced the upper fan shroud which broke because of the engine raising so high. And all the steering column bolts are tight. I am at a total loss. Any insight here??? I had a rare NONE buzzing interior before all of this now i dont even drive the car because it buzzes so much. When parked and revving the vibration gets louder all thr way to 2500 and kind of plateaus...

Did you replace the motor mounts after dropping the car off the jack? You may have ripped one (or both) of the motor mounts. That or the crank is contacting the oil pan where it dented it. If the crank was contacting the oil pan, you'd probably know and wouldn't want to drive the car because of the terrible noises it'd be making...

[RalliartRsX]

Wait, how were you jacking the car up and with what type of jack?? If you were using a scissor jack and using the crossmember, that is a reciper for disaster!

Also, you replaced everything except for the most essential part (THE OIL PAN)?!?!

Did you even check the surrounded areas (to the oil pan) for damage? If it smashed the oil pan (and I am pretty sure you did a number on it if the vehicle had a few inches to go before oil pan/jack contact), there is a good chance the oil pan and surrounding medium may have been compromised to a certain extent

You need to SAFELY jack the car up! I have never had an issue using a floor jack and jacking up my 240 by the MIDDLE of the cross member at any point in my ownership. You really should be keeping an eye on the jack movement as as the jack rasies, the moves towards the front, so you have to jack it up with that compromise in mind!

[nazgul]

Yes everything has been replace after this incident. No i was jusing a floor jack in the center of the front subframe the pan is crushed in on the right rear so im mot worried about it interfering with the pickup. The engine overall makes no more vibration than normal only upon sitting in the car is there the buzzing. My guess is it is steering column/ rack related what do you guys think

[zach3904]

What motor mounts are you using? Did you run the car between the time you smashed the oil pan to when you replaced the mounts?

[nazgul]

I am running drift freaq mounts. Yes i did it is buzzing and vibrating the steering wheel the dash the same as when i first started the car after the incident as it is now with the new mounts and trans mount. I havent been driving the car at all except a couple days ago after i replaced my tension rod bushings. In cabin is overall buzzy from 650rpm to 2500 which is where the buzz tapers off and doesnt get any louder. However the column buzzes mostly when im going straight and gets a tad less noisy when im turning. I just dont see how i could have damaged a steering component. Nothing in the way of the motor going upwards is near the steering rack/column connector/column...i Seriously jave gone through the entire drivetrain with someone revving it and nothing is shaking or vibrating everything it tight and seems perfect

[nazgul]

The pan is only dented in maybe one inch in the far corner of the oil pan. There is no way the counter weights are hitting the dent its the lowest part of the pan. I know the pickup could have issues but thats why im not driving the car till i get a new pan.

[TheRealSy90]

Fix the part that is still messed up and then come back...

[racepar1]

Did you smash any of the power steering lines around the crossmember when the jack slipped? That could cause odd noises from the power steering system. The Driftfreaq mounts do take a little time to "break in" where they cause some vibration, but you say the vibration was there before the mounts were installed as well right?

[nazgul]

No i didnt mess the lines up, the jack slipped off the crossmember towards the front of the car and went right to the pan. And yea correct, the vibrations have remained the same after the mounts and everything, very frustrating. Oil pressure is still good so the pan being dented is not an immediate issue for me because i dont drive it.

There are power steering lines running along the front of the crossmember. If the jack slipped back into the front of the crossmember they could easily have been smashed. Have you actually looked at them or are you just assuming?

[nazgul]

There is only 1 hardline going right under the lip of the subframe correct? Ita tucked away under the lip? If so then that one didnt get hit and is still in place

[racepar1]

There should be 2 lines on a singlecam and one looped line on a dualcam. Did you actually look at it? There aren't many possibilities to cause your complaint, a smashed hardline seems the strongest to me. Assumption is the mother of all fuck-ups...

[nazgul]

http://i45.photobucket.com/albums/f65/michaelharting/Pictures013.jpg so this would be a single c? I have a dohc and im pretty sure it has one line thats sitting in that center clip in the pic...ill check when i get off work though and see

[nazgul]

I have noticed though that there is a faint wine that goes with the rev of the motor, getting louder as the rpms go up and it is deffinately a power steering soundi hope to god this is the problem

[nazgul]

Whine***^^^

[blueshark123]

"I am running drift freaq mounts" -Clearly this is why your car buzzes now. These are more solid then oem. Which will cause chassis to shake more with engine.

Im shocked no one pointed this out to him. A little buzzing for me may seem like a lot for you. 240sx aren't quiet rides especially at this age.

[TheRealSy90]

The engine crank hitting a dented oil pan would have no affect on the oil pressure...

[racepar1]

OP: Yes, that is the dualcam setup."I am running drift freaq mounts" -Clearly this is why your car buzzes now. These are more solid then oem. Which will cause chassis to shake more with engine.

Im shocked no one pointed this out to him. A little buzzing for me may seem like a lot for you. 240sx aren't quiet rides especially at this age.

He also said the noise was present BEFORE the drift freaq mounts were installed... EVERYONE TALKING ABOUT THE CRANK HITTING THE OIL PAN: A crankshaft hitting the oil pan would cause a knocking noise, NOT a buzzing noise like the OP is complaining about. A badly restricted power steering line could cause a buzzing noise from the power steering pump and could transmit vibration through the steering column, which is why I mentioned it. That's the ONLY thing that I can think of that could have been damaged when the jack slipped that could cause the OP's complaint.

[blueshark123]

Didnt see he said buzz was same before the mount as it is with new ones.

[TheRealSy90]

All i'm saying is it's a pain to troubleshoot someone's issues when there's other stuff that is clearly wrong with the car. It's like trying to figure out why the steering wheel shakes on my 91 civic when every bushing is original and the steering rack and tie rods are worn out, BUT I JUST DID NEW WHEEL BEARINGS WHY DIDN'T IT FIX.

[nazgul]

No shit.....if your read any of my posts you can clearly see i am referring to the pickup to pan clearance possibly being an issue...however the dent does not stretch all the way to the location of the pickup tube so the pan is fine for now. also the car had zero interior rattle or vibration to begin with..AGAIN if you read any of my posts you would have known all of this. You come off as a major douche and id like it if you didnt comment anymore thanks @ therealsy90. Everyone else is being of help and ill get back with info on those pump lines by the crossmember

[nazgul]

The power steering lines are ok and didnt move, the subframe is not loose. The shifter does show signs that maybe the linkage got smashed or something got bent. this car is an auto. The shifter is kind of sticky when changing gears which WASNT like that before the incident

[nazgul]

I have decided the steering column is the culprit REASON: the egr pipe is only 1 inch under the steering column/linkage bar that goes into the rack. So i think the egr pipe slammed against the bar and bending it or maybe destroying the steering column bushing? Or do you think the bushing would break and not bend the bar? Either way im pulling the column now to look at the firewall area and see if theres some metal on metal or something messed up

[J3123MY]

LOL LOL LOL. GG. Should have jacked it up right noob.

[racepar1]

Where is so-cal are you located?

[nazgul]

I stay in la habra

[racepar1]

Damn, if you were in my area I might stop by and have a look just because I'm curious as much as anything. You're too far out there though...

[nazgul]

I appreciate it man haha ill just have to keep looking amd ill eventually find it. im going to disconnect my water pump and p/s pump belt and run it and see if it stops it. In addition to checking motor mount brackets that go to the motor for being loose. Also Remove the steering columm to steering rack connector bar and run it. Besides that i can only think maybe i bent my flywheel or something..other than those 3 things i am completely out of guesses and ill just buy a speed sensor and do my 5 speed swap thats been sitting since before all this crap

[Sleepiedaze]

Sarcasm :: its all about that drift life YOLO shit bro! just run it till it blows up.

but honestly fix the dented oil pan first. The motor mount's are your first bet but the sound was there before the mounts. usually buzzing sounds are related to differentials. powersteering issues are more of a whine sound. oil issues are more of a knock sound. take a peek at your drive train may be in need of some love. the fact that you dropped the car is a seperate issue.

grammer nazi : i code for a living no need to

[blueshark123]

Bent flywheel in a automatic car. Thats a new one

[racepar1]

Disconnecting the belts and running the car is a good idea. Do it one at a time so if it does make a difference you can isolate the issue. I really don't see how a steering column or any loose brackets anywhere could possibly cause the noise, but you never know. As long as your trans is actually bolted in place there is absolutely no chance that you bent the flexplate.

[nazgul]

Well i removed the entire steering column and started the car with just the ignition switch hooked up and it disnt change anything still have my dash and door panels humming... F**KKKK!!!

[nazgul]

Removing the belts didnt change anything either..

[nazgul]

Bent flywheel in a automatic car. Thats a new one theres the word i was looking for lol nice burn

[jedi03]

Dynamat it all!

[1988montecarloss]

the jack didnt hit the harmonic balancer/crank pulley by any chance did it?

[nazgul]

So I have tightened everything down checked everything out a million times and nothing has fixed it. I put in a dif aluminum steering bushing for shits and it did nothing to help nor make it worse. I have decided it is the engine causing the problem you can feel the engine just feels out of balance overall. It shakes the steering shaft as much as the bottom of the pan vibrates. The engine has an overall "high frequency vibration to it and it is just causing the subframe to transfer that to the rack and into the steering. Does anyone think the pan touching the pickup could cause the engine to vibrate like it does? I'm not talking oil starvation either...It has to be the motor somehow vibrating the shit out of my car
