Take it a part and do it right or you will only tear it up worse when you clean it and get it running again.

My car keeps over heating

if's it's not leaking water. then your thermostat may be stuck in the closed position and will need replacing. if thermostat is easy to remove you can try removing it and see if it still over heats. also check the water pump, there is a small hole in the housing and if it's leaking water out of the hole then the water pump is bad.

It ran out of oil and now it makes loud noises and only runs for 2 minutes. What engine parts might be damaged?

Any moving part relying on lubrication can be affected by lack of oil.

Sounds like the engine is FUBAR!

Timing belt broke - I am trying to replace it - can't find timing marks for TDC

some engine dont hav markings they have a little access hole on the fly wheel side so that you can lock the crankshaft in place at tdc using the correct tool or bolt or some thing similar...u cud try remove the spark plug on cylinder 1 and insert a long screw driver turn the crankshaft and watch the screw driver until it reaches highest point with valves on cylinder 1closed that will be close recheck for marks.. not sure on your engine but most modern engines are interference engines which means if your timing belt snaps when the engine is running your piston/s will come into contact with your valves which will result in bent valves at the very least..which will be catastrophic to the engine hope this jelps

The piece that turns my belt broke what is that

The part that turns your belt is the crankshaft and crankshaft pulley. If you are right about the crankshaft being broken, then your engine will need rebuilt. But in most cases it is cheaper to buy a rebuilt engine from one of the professional rebuilders. Check with you local auto parts stores and they will be able to advise you on the best rebuilder to use.

I have a 2004 FLHT with 64000 miles the bike is still running very strong should I be thinking of doing any engine work to avoid engine failure in the future.

Not unless the engine is smoking, or knocking or something. It depends on what kind of maintenance has been done on the engine. Evidently, the maintenance has been done pretty well. I've torn down Evolution model engines with more miles than this on them and found the bottom ends to be in very good condition not needing a rebuild. Your top end may need a refreshing. It may not even need boring. I'd check the piston to cylinder wall clearance before I bored it. It may just need a new set of piston rings and a valve job. Don't go jumping in rebuilding your engine just because you think it might need it. Ride it until it quits. It won't cost you any more.

Good Luck

Hi, i recently bought a yamaha blaster 200cc quad bike and when i went out on it i forgotten to put some 2 stroke oil in with the fuel tank, and when out on it. now it wont start, please could you tell me...

you probably seized the engine. The piston rings have most likely scored the cylinder wall. At the very least you will have to rebuild the top end. Oversize rebuild kits are available. You will have to have the cylinder bored to a larger diameter to accept the oversize piston kit.

The crankshaft is also lubricated by the oil in the fuel. There is a possibility that the crankshaft is also toast due to lack of lubrication. You will have to tear the engine down (top end) to verify the damage. you could remove the exhaust and look into the exhaust port to view the condition of the piston.

You may be able to find a used engine at a reasonable cost from the internet. Google search.

What is the thing at the bottom of the fan belt hooked up to?

Not sure exactly what you mean, but normally, the lowest pulley is called the crankshaft pulley, and also includes the vibration damper (technically a counter-weight), and this is all connected to the crankshaft, which is driven by the pistons. The crankshaft runs the length of the engine, and drives the transmission at the opposite end.
If that does not help, you will need to be a bit more specific in your description.

03' santa fe 2.7 liter V6 water pump seized,causing the timing belt to strip on the crankshaft timing sprocket. The belt did not break,but striped the teeth off the belt.Yes, the crankshaft did turn...

replace the belt with a new one, when you do the water pump,reset the timing and give it a start,if it works,then you can SMILE,if not, you can use the belt/water pump on the new engine.gotta be the cheapest way forward.......

Ticking noise from under engine and when stopped oil indicator comes on but goes off when accelerate, 71,000 miles have read horror stories about possibly having to replace engine due to sludge, any help...

It would seem you have damgad crankshaft bearings. If so the ticking noise you hear should be louder on acceleration and can be better described as a knock. On an engine with your mileage it is a little early but is normally caused by infrequent servicing.
The engine can be repaired but it has to come out. On a tight budget a crank resize and oversize bearings will sort it out in the short term. Unfortunately if the bearings have failed then the pistons and liners are probably also worn out. This can also be repaired but you will have to shop around (as listed below) as to what solution is best for your budget.
  • New engine will be most expensive but will last longest.
  • 2nd hand engine(or just the bottom end aka block) vs bottom end rebuild.
  • Complete 2nd hand engine.
If the rest of the vehicle is still in good shape I'd go for a new engine or a complete rebuild. (The rebuild is cheaper, but does not last quite as long, depending on the mechanic, engineering shop and quality spares used)
A 2nd hand engine may be in the same condition as yours.
