Hi Anonymous, it can be repaired by an experienced aluminum welder but you will probably have to remove the engine. The best thing to do is call your local dealers service department or reputable shop and ask them if they can do it or recommend someone who can. But no matter who does it make sure they disconnect and isolate with tape or heat shrink the battery cables if the repairs can be done with the motor in the frame, as not to fry you electronics. Good luck

SOURCE: cracked frame

Suzuki replaced my frame about a 1.5 years ago.I was 3rd owner,9000 miles on bike,all stock and original except pipes.The only drawback was I had to pay for the labor,which was about a $1100. I knew the mechanic at the shop and they let me do the labor myself.The frame was cracked on both sides where the radiator mount screw into the frame.

SOURCE: I?m buying a 2000 Suzuki GSX 750 that was laid down

HI, I had a 2002 gsx600f, pretty much the same bike and I let a buddy of mine ride it and he came back with the oil pan cracked, turned out he tryed to ride a few wheelies on it and upon one of the landings the weight of the bike actually cracked the oil pan, they are extremly heavy compared to other sport bikes on the market. Ive never heard of an oil pan just cracking, more then likely it was user error.

Why is my car loosing antifreeze

There can be numerous reasons for coolant loss.

External Coolant loss
1. Coolant escaping from the radiator cap. Replace the cap.

2. There is an external leak in the system which could be from a hole or crack in the radiator(especially the plastic sections) or a hole in a radiator hose or there is a loose hose connection.

3. The water pump gasket has deteriorated and coolant is escaping from around the water pump fitting.

4. There is a crack in the coolant overflow reservoir and coolant is leaking out.

Internal Coolant Loss
1. Coolant is escaping into the engine's cylinders in which event you will see white smoke coming out of the exhaust and you will also have combustion gasses leaking into the coolant passages which will cause bubbles and overheating of the coolant. This problem will be due to a failed cylinder head gasket, a crack in the cylinder head or both.

2. Coolant is escaping into the engine lubrication system and in that event you will see evidence of coolant in the engine oil. Pull the oil dipstick and check the condition of the oil. If it looks a bit like chocolate milk and not just normal oil colouring you have coolant in there. Also check the radiator cap when the engine is cold. There may also be evidence of oil in the radiator coolant that is stuck to the radiator cap and around the neck of the radiator.
This problem will also be due to a failed cylinder head gasket or a crack in the cylinder head or both.

Whatever the cause in your case don't hesitate to have it checked out by a competent professional If you lose coolant and you allow the level to run significantly lower than normal the engine will overheat and you will cause very expensive engine damage.

My toro 6.5 hp leaks oil at the bottom of the engine runs ok

If this is the vertical shaft motor, there is a seal at the bottom where the crank shaft exits the case. On the vertical motors I've taken apart, the bottom of the case is like an oil pan. It is possible that you could have a crack in the case. But also check the oil drain plug to be tight, but not too tight. This could also cause a crack in the motor case.

1998 Olds Intregue, 3.8L about 80K miles, started making loud engine noise. Tore down and found crack in lower intake manifold. What would cause this? Is it worth replacing? Should I be checking for...

If the intake manifold is cracked, maybe try to put some puddy epoxy in it to repair. I've found puddy epoxy useful in repairing leaks in other parts of the engine, including a rusty oil pan that was leaking oil. I think that puddy epoxy would be ideal for this crack. Probably, you are hearing the valves clacking if there is a crack there.

How much did you tear the engine down?

Chain oil leaks out quickly a rancher 55

Remove the bar and chain. Clean the engine side case where the bar fits. Does the oil port itself leak or is it coming from the engine case? If from the case, it may be a loose or split line from the tank or it could be a cracked oil tank. If the tank is cracked, replace it as there is no glue or epoxy that can permanently repair it. If the leakage seems to have stopped, clean the drive end of the bar including the two small oil passages that run out to the chain groove. Re-assemble the bar and chain, then run the bar tip at speed near some cardboard for a few moments--it should throw off a thin line of oil. This saw should have an oil volume adjustment screw located near the chain return area on the back or underneath the case. Adjust CW to reduce the oil volume. Hope some of this helps!

I have a crack in my engine whats the best way to fix it?

It really depends on where the crack is located.
The engine is actually separated by the engine block and the cylinder head.
CYLINDER HEAD - located on the top of the engine where the spark plug is located
ENGINE BLOCK - located just below the cylinder head and separated by a gasket.

I believe you can buy them separately.
Because if there's a crack on the engine replacing the part that has a crack is the best thing to do to avoid loose compression and oil leakage.

2003 L200 2.2 ecotec w/ crack in head

the crack is possibly in a oil pressure gally and that would by why there is pressure behind it. there is no fix and this engine is not notorious for this problem. if the engine has low miles i would just replace the cyl head.

Oil pan crack

yes, it could have caused this. You have to prove it with the insurance company, by getting a mechanic to say this is what hit it and caused it to hit the pan.
