Engine vibration is an indicator that the bottom end needs to be rebuilt. Checking for excess “play” in the crank with the top-end off is a sure way to tell. If there’s up and down play or a lot of side to side play, the crank bearings are more than likely worn out at a minimum.
Can you straighten a bent connecting rod?
If you try to straighten bent rods you WILL be redoing the motor very soon. Like others have said that rod is bent it is now weaker and you are just bending it again. Ever take a paper clip and bend it around till it breaks? Dont do it.
Can you drive a car with bent valves?
A bent valve could start a fatigue crack in the stem and if it breaks you drop the valve in the cylinder. You could also hammer the seat beyond where a valve job could fix it or (it the exhaust valves are bent) burn the exhaust valve(s) up. I wouldn’t do it.
What would cause a bent connecting rod?
First cause – Hydraulic Lock – This happens when there is liquid fuel in the cylinder and an electric starter is applied to the engine. Liquid will not compress like a fuel and air mixture so the only thing that can happen is the rod will bend as the piston is stopped prematurely at the top of the stroke.
What happens when a connecting rod goes bad?
If your connecting rod is failing, it will increase the rate at which the engine consumes the oil. As a result, the oil levels in the engine will always read low. It means that the present oil will need exchange often than usual. Also, it’ll increase the cost of running your car, boat or the machine you’re operating.
Can a car run with a bent rod?
This! But motors can run on bent rods. And bent rods don’t make any noticeable sounds in particular. If you suspect the rod possibly hitting something else internally, the rod would have snapped by the time it had any chance of doing that (so I would think, especially with ~300ctq at a minimum with your setup).
What are the signs of a bent valve?
The symptoms of bent valves include an engine that won’t start, an erratic engine when idling, lack of engine power, a knocking noise from the engine and excessive exhaust fumes.
