No because the cylinder is twice the size of the old one if u put a 250 head on. Then the bolts wouldn't line up and it u had 250cc 2 stroke power on the 125 trannie you would be screwed
make steam
Yes. Make sure the beveled edges of the cylinder head-bolt washers face the bolts, and the flat sides face the cylinder head.
Depends on who performs the repair, what make, model, and engine size, and if there was no damage to the head or not.
valve who needs ajustment
Depends on the engine size, make, and model which you fail to list.
Buy gasket paper off eBay. This will stop blowing and make it run.
Cylinders are basically pipe, or tube shaped. To make them useful they have to be sealed off at at least one end. And the part that seals them off, where you often finds valves and stuff, is called a cylinder head.
Without make, model, year and engine displacement there is no way to answer this question
Your question is incomplete --what make, model and year car?
You cant do it. The head gasket is the most important gasket in the engine and it is very specially made.
to replace the cylinder head you should get a chiltons book for your year make and model of your vehicle. If you have never replaced a head gasket before you should take care to make sure the timing on the camshaft and crankshaft are set to top dead center before removing the cylinder head because most volkswagons have an interferance engine which means the cam and crank must be timed properly or could cause cylinder valve damage. Take cylinder head to a machine shop and have them check the cylinder head for warpage with a straight edge after you have cleaned off the gasket and any material on the head. If cylinder head needs resurfacing, make sure the machine shop does this. Follow directions carefully to retorque the head down (if needed replace head bolts if they are torque to yield bolts). Make sure you repair the problem that caused the cylinder head gasket to leak. This problem could be anything from a leak to bad thermostat, or even a bad water pump. When i replace a head gasket I always replace the water pump and thermostat and flush the radiator, heater core and change the oil twice before driving. Most newer volkswagon vehicles have an air bleed procedure to get the air out of the cooland and to condition vehicle for proper coolant flow. check procedures and follow exaclty.
It is the space between the top of the piston and the bottom of the cylinder head. Great care should be used when putting an engine back together to make sure the bump clearance is not 0 so that the piston will not hit the head cylinder.
