Question about 1999 Ford F150 Regular Cab

4 Answers

My truck was stuck in a river. Took out plugs and got the water out of the motor. As i was trying to start it (it started to run rough a few times) when we heard a loud snap and the motor locked, we backed the flywheel a couple of turns and tried it again and something punched a hole in the oil pan. is it possible to fix this without replacing the motor?

    i have a buddy thats a mechanic and he thinks we could remove the oil pan and replace any broken parts as long as it didnt damage the block.

You have thrown a rod, the connecting rod for the piston to the crankshaft, this will require that the engine be removed from the truck, the condition of the crankshaft, and block will determine if the engine block itself needs to be replaced. This can not be fixed with the engine in the vehicle, you may just want to find a good used engine and replace it, hope this helps, let me know

What you Have Described is Indicative of Throwing a ROD. Practically the ONLY thing this Can Be Is A Connecting rod Broke Loose and was Ejected Into the Oil PAN this Is FATAL Engine Damage.
To Fix it Without Replacing the Engine ? YES But Engine Must be removed and Disassembled to repair it and the COST Would Be Excessive.
Best Bet is Replace Engine, New Engines Have GOOD WARRENTEE"S --- Used Engines have SHORT Guaranties BUT With a SKILLED Technician Doing the Selecting for you along with Finding one With LOW MILLAGE then you get off Much Cheaper that NEW One. Hope This Helps and Sorry to Have BAD NEWS on Your Engine

You can replace the connecting rod you broke without removing the engine IF you have no damage to the cylinder wall or main webbing Cylinder walls must be measured to detect any bulges (rod broke due to hydrolock) It's likely that the big end of the rod is still intact so crank may be OK.
First remove pan...most damage will be on the bottom. If no damage seen other than the rod, remove the cylinder head & check bore. It is wise to check all rods for bent condition if they too ingested water. If all is good replace piston and rod assembly and put it back together. Or, get a different engine, put it in and repair the broken one when you have the time

It is possible to repair the engine in the vehicle if the pan can be removed and inspection of the block passes. The problem though is that the crankshaft cannot possibly have survived this catastrophe, and the engine or the transmission must be removed in order to remove the crankshaft for replacement. If you miss any detail the engine may fail again and be all for naught. If it were me, I would be finding another engine. Consider also: the transmission, rear axle, brakes, fuel system, power steering (if equipped) all need purged in order to avoid finding yourself stranded in the near future.

when a motor has been cooked ( run with out water ) the rings loose tension , the pistons score the cylinder walls, the head cracks or warps and the head gasket generally blows. In mechanical circles , your best option is a replacement motor either from an engineering rebuilding shop or a good unit from the wreckers.

Ford 1981 f 150 not running changed Coil distributor cap Roar arm plug wires did not help started bur ran extremely rough then died


motors need 3 things to run properly. gas spark and compression. the starting point. also spark timing.
the motor you are dealing with is easy. i just rebult a 1978. anyways sounds like a timing problem . first i would check the distributer. if all is ok spay a squirt of starting fluid in the air filter, or even wd40.,,,,,,,see if it is gasoline problem. isolate where the problem is.

Overheating engine that runs very rough


Your mechanics are worthless, trying to charge you for **** you don't need. Water pump or thermostat is possible. No. If it started blowing cold that means that either you were completely out of water, or that there is a stop in the water passage way somewhere. A sticking thermostat could be it, and maybe the water pump might be going out, doubtful tho if it works sometimes. I would replace the thermostat and see if that fixes the over heating problem.

Another thing, is the timing of the motor. That will cause it to stall at a low rpm and run rough, and also can cause over heating due to it detonating. Buy/rent/borrow a timing light and hook it up to the number one cylinder spark plug wire and shine the light at the harmonic balancer on the crank and check for timing. There should be lines on the crank and the block that line up if it's timed correctly. And the air pump shouldn't be bad or need a belt (if it's still spinning) but pull a vaccum test on the motor to see what the vacuum is at. Hopefully, this has helped you. Buying a repair manual at you local auto store should help you with changing your thermostat, timing, and vacuum test as well as what the vacuum of the motor should be.

Engine runs rough


soo many mechanical possibilities if you started a frozen motor..do you plug vehicle in with a water heater at night to keep it from freezing where you live?...you'll need to have a compression test to determine if a ring or valve train component didnt break from starting it when frozen..
