I have a Chevy 350 and the bolt that was holding it up broke and it fell on the oil pan what problem I will have

I was wondering what problems I will have if a Chevy 350 dropped on the oil pan
Experienced mechanics share their insights in answering this question :
The damage that has occurred from a fall will depend on how far the motor fell. The possibilities I’m providing here are just probable and should not substitute a thorough inspection of the motor. If there isn’t any visible damage, then it is likely no damage has occurred.

To start, if the pan is bent enough it can damage the oil pump pickup tube and screen. This can cause a loss of oil pressure if cracks have developed in the pickup tube. It is also possible that the bottom of the pickup tube and inside of the oil pan are so close that it restricts the volume of oil supplied to the motor.

It’s also possible that the pan has been twisted enough to create oil leaks at the front and rear of the pan. These sections of the pan are common areas where oil leaks occur when a pan is in new condition. If the pan has been tweaked, these sealing points can be further compromised.

Other than the pickup tube and oil pan gasket sealing points, there are many other less likely possibilities that all depend on the distance the motor fell and the angle it hit the ground, if it hit the ground. Cracks can develop in the block if the impact is hard enough. The pan can be twisted creating interference with the oil filter, oil cooler lines, harmonic balancer and other items. There are many other things that could have been impacted by the fall. I am assuming only the oil pan was impacted.

As I stated before, there is no substitution for a thorough inspection of the entire motor when something like this occurs. I would advise you to have an experienced mechanic take a look if you have any doubts. As an experienced technician, I wouldn’t worry about anything if there aren’t any obvious signs of damage. Since I cannot inspect it myself, I can only speculate.

How to Identify and Fix Common car Problems ?

If you drop a bolt or part into the engine itself, you`re about to have a bad time. Unlike air and fuel, metal bolts don`t compress well inside an engine. In fact, they`re more that likely to cause permanent replace-expensive-parts kind of damage.
It will damage the valve, valve seat, and then beat up the piston and scar the cylinder. The nut could put a hole in the piston and lose the cylinder if it isn`t retrieved.
Any welder, auto mechanic, machinist, or millwright will be able to help you with a broken bolt. The procedure is not difficult, just takes time.
Bolts can fail by due to several reasons including (1) the bolt had not been sufficiently preloaded/tension during installation, (2) had lost its preload during service, (3) the applied cyclic loading had been excessive – far beyond the strength of the bolt and/or (4) the bolt had been understrength (quality issue/ …
Option 1: Welding on a Broken Stud

To start, select a nut or flat washer with an inner diameter roughly the size of the stuck threaded bolt. Place the flat washer and/or nut on the bolt and weld the inside of the nut to the broken top of the bolt. Then use a wrench to remove the nut and bolt together.

Problems with the carburetor are often attributed to the part becoming dirty. In addition, different parts can fail within the carburetor. For example, if the power valve inside the carburetor becomes bad, a misfire in the engine will occur.
If there is dirt or debris in the fuel bowl, it can block the needle valve and prevent it from closing. When this happens, fuel overflows into the carburetor. This causes fuel to flow out of the bowl vents, throws off the air-to-fuel ratio and gets the spark plugs wet.
Drift it out: If the bolt is not entirely seized you may be able to drift it out. If there is a burr where it broke off you may be able to get a screwdriver or small chisel behind it and tap it out with a light hammer. Failing that use a centre punch by tapping a hole near the edge and then using it to turn the shaft.
Lefthand Bits or Screw Removal Kit

Lefthand drill bits or a screw removal kit can extract rusty screws by boring into the screw. Lefthand drill bits are slightly easier to use than a screw removal kit because the bit simultaneously bores and turns out the screw.

Turn on your torch and aim the flame directly at the bolt head. Move the flame in a circle around the bolt for 30 seconds. Use a socket wrench to rock the bolt back and forth until it loosens enough to be removed. The bolt is stubborn, repeat steps 2 and 3.
To use a screw extractor to remove a screw, drill a pilot hole into the center of the damaged screw, using a power drill and a twist bit of appropriate size. If the head of the damaged screw is rough or uneven, it can help to start with a very small pilot hole, such as a 1/16-inch bit.
Center-punch the broken fastener and drill a small pilot hole to get started. You do not want to, under any circumstance, break the extractor off in the fastener. Because the extractor is traditionally harder than most drill bits, you will then never be able to get the broken bolt out.
The break will almost always be directly under the head of the fastener and not in the threads. The head may break off completely, or it may simply crack enough to relieve clamp load, and remain attached.
The rust can freeze the bolt in place or degrade the shape of the bolt head or the nut holding the bolt. If you try to back the bolt or nut out with a wrench, the wrench won`t grip the hex head, making it difficult (if not impossible) to remove.
File down the top of the bolt with a metal file until the surface is perfectly flat. Place a bolt removal bit on this flat surface. Turn the bit until it locks into the bolt. Twist the bit back to the left to turn the bolt and remove it from the metal.
That`s not good for a couple of reasons: 1.) Your tire could blow out, and 2.) if the hole continues to grow, you run the risk of ruining the tire altogether.

lost all oil pressure, replaced the oil pump, low oil sensor, oil pressure sensor, oil pan gasket,
ANSWER : The fuel pump will not stay on if you loose oil pressure. This is why it is shutting off. The loss of oil pressure may be from bad crankshaft bearings or camshaft bearings. The engine oil pan should be removed and the oil pump needs to be checked to ensure that you put in the pick up tube seal to the pump and connected the pump to the block. Then remove at least one main bearing cap and inspect the bearings for excessive wear and crankshaft damage. If you need some help with this, consider YourMechanic, as a certified technician can help diagnose the issue with your oil pressure firsthand and help you fix it accordingly.

I have half of my oil pan bolt in my oil pan . What can i do?
ANSWER : The threads in the bolt gallery can be repaired by a tap and a new bolt can be installed into the cleaned gallery. If you need to install the bolt for now and fix the gallery later, you can take a small cotter pin and put it into the gallery and then tap the bolt in against it. Then you can tighten the bolt to torque specs. Be sure to remove the excessive cotter pin that is sticking out. This will hold until you get a bolt and tap out the old threads. If you need further assistance with your oil pan bolts, then seek out a professional, such as one from Your Mechanic, to help you.

2006 Ford Escape oil pan is sweating, is it the gasket or is it the pan?
ANSWER : Well I’m not sure about the mechanic’s use of terms. If the oil pan is "sweating" oil, then that would dictate that the oil pan is already porous. It’s not an everyday thing to happen but I have seen it a time or two. It generally happens in regions that have harsh winters and lots of road salts are used. The oil pan rusts through and begins to seep, or sweat, oil. Without seeing myself, I really can’t say whether it’s the pan itself or just the gasket. Either way, the oil pan has to be removed to replace the gasket. So if it actually turned out to be a leaking pan, it’s just the cost of the replacement oil pan.added to the repair. The labor is no different.
Differentials generally use gear oil of different weights depending on the application. Diff fluid is basically a very thick oil so it would generally appear as dirty oil on the ground if it’s leaking.

Oil pan covered in oil, but no dripping
ANSWER : If your oil pan is covered in oil, that means you have an active oil leak that may be coming from higher up on the engine. The valve cover gaskets may be leaking and running down to the oil pan. You may need to have the entire engine cleaned. Afterwards, leak detection dye can be used to see where the leak is coming from. From there you will know where the source of the leak is and change your oil and filter. In the mean time do not let the engine get low on oil.

If you need assistance with this, contact a professional mechanic who can pinpoint your oil leak and make the necessary repairs. They can also service your cars oil/filter needs as well.

Ignition coil bolt can’t bolt down
ANSWER : The valve cover on that side of the engine has the broken bolt boss. The only way to secure the coil is to either replace the valve cover so you have the bolt boss to bolt down the coil, or to change the coil involved in the misfire.

I’m trying to purchase an "EcoPlug" for my stripped out drain plug. How do you determine if your oil pan is aluminum or steel?
ANSWER : VW may be making the replacement oil pans from aluminum for weight and/or cost savings . If the magnet is sticking to your oil pan, then it is steel as a magnet will not stick to aluminum. Hope this helps.

After an oil change, I was told that I needed an oil pan reseal. Is and oil pan replacement basically the same thing? 2007 Volkswagen Beetle
ANSWER : Hi there. An oil pan reseal means that the oil pan is removed and the gasket or seal is replaced and then it is reinstalled. An oil pan replacement means that the oil pan itself needs to be replaced. It is the same amount of labor but one of these jobs will simply have more parts involved.
