SOURCE: ticking noises / Spun Bearing

If it is a light ticking noise it could be something as simple as tappits on rocker arms. valves pinging..........IF it is a ticking and not a KNOCKING noise then i would have another mechanic take a look at it...Sad thing that happens is some mechanics will give wrong suggestion for the simple fact of making your wallet lighter.... not saying this is the caes but something this costly needs more than one mechanics opinion. My suggestion would be have another mechanic look at it not telling what the first mechanics opinion was and then see how they compare..... hope this info helps and good luck....Please rate my post.

Chances are you might have spun a main bearing with the coolant in the oil for some time. With a main bearing spun, no oil will curculate thus seizing your engine. Do the lights dim when trying to crank?

Hi
The wheel bearing may carry the magnetic ring that the abs sensor uses to pick up a reading.
Replace bearing if its faulty and retest all as before.

Spun bearing


You are up for an engine rebuild. Remove the engine and turn up side down in a stand. Remove the sump and find the failed bearing by taking off the big end caps. If you find a con rod damaged you will have to remove the head and that piston and replace the con rod. If it is a main bearing that has spun you should only have to replace the crank shaft and fit new bearing shells Either way you will need another crank shaft. Check the price of a low mileage engine from a wrecker as it will be quicker and possible cheaper in the long run

Oil presure gauge went to zero and computer said low oil presure! I then heard a loud knocking coming from engine! I check level of engine oil and its full, what do you think it is?


You didn't state the mileage (would help with diagnosis) But unfortunately you have suffered major engine damage. And that would depend if the knocking you hear is steady at engine idle or only knocks when reving the engine . For some reason the oil pressure did fall to zero, most likely due to bearing wear but again depends on mileage. If knocks constant at idle it is a spun main bearing, if knocks only while reving engine it is a spun connecting rod bearing. Either require an engine overhaul. Or engine swap, Once again it depends on how many miles you have the engine to determine if its wise to rebuild it or replace it. I hope this answers your Q.....

How do you repair spun bearings on a 1994 Mitsubishi eclipse Gst ?


if the bearings or even one bearing has spun, the lower end of the motor needs new bearings and the crankshaft must be "turned" or resurfaced.. this requires pulling the engine... if you drive this vehicle in this condition, you will have catastropihic engine failure which would totally destroy the motor probably.. If you or someone has the expertise to remove the motor, putting in a "crank kit" is not difficult for anyone with a little mechanic experience.. but, basically, this is time to rebuild the motor whether you just do the crank kit or go ahead and go all the way with it since you already have it out and opened up...

Engine knocks loud


Sounds like a bearing in the camshaft or rod bearing is seized or spun. Needs an engine overhaul to repair if you want to keep the same engine.

Uhh there are no rods in the head. That dealer has a loose rod in his head maybe.
The crank, rods and pistons are all in the bottom end of the engine.
What it likely is is either a broken piston skirt or a spun rod bearing.
Spun crank bearings are rare and sound deep.
A spun rod bearing can be fairly quiet on idle depending how bad it is worn out, but it will be really loud on acceleration. Piston slap from a broken skirt can be pretty loud too but it mostly sounds like diesel rattle only a bit less. Some have described it as a loud pinging sound like detonation.
Drain the oil and check for metal debri. If you can tilt the vehicle a bit for the oil to drain more towards the drain hole that could help. Then look for metal pieces and judge their size. There should be NO glitter whatsoever in engine oil, or any kind of debri. Now a rear end or transmission is different. Those always have a little metalic sheen to them.
Best of luck.

I have a spun rod bearing, and a scored crank


Talk to an engine rebuild shop near you. They should be able to save your crank if it's not broken, and get you a set of bearings and piston or anything else you need. They'll be in the Yellow pages.
