How do you replace a blown head gasket on a 1975 Buick 350 4 barrel?
first you need to remove the valve covers and the intake manifold and the upper raditior hose also the distribuitor after you take all that stuff of you should see the large bolts that holds the head to the block take them off and remove ALL the old gasket off the head and block and put it pack together by tightining the heads from the middle out same with the intake
whoever posted this answer is caorrect, but i'd like to add on what has already been said. Be sure to drain the cooling system of all the coolant. this can be done by removing the lower radiator hose. alos, whenver you work on the enigine, be sure to disconnect the negative battery cable, as this helps preent accidents whernver service is being done.
If you have the 3.3 engine then the answer is "NO". They do not have a history of blowing head gaskets. The other person probly had all different motors I have a 98 Buick century (blown head gasket). My father in law has a 94 Buick century (blown head gasket). mother in law has 96 Pontiac grand prix ( has the same 3.1 liter engine as the Buick century) and guess what (blown head gasket)…
If you remove the head then of course you replace the head gasket. Where can you get sodium silicate to fix a blown head gasket? Know that adding sodium silicate to an engine is only a temporary fix for a blown head gasket and will not permantly fix the problem. The only permanent fix is to replace the head gasket. I would never add any head gasket fix material to any engine.
After a blown head gasket was repaired on your '94 Buick Skylark 2.3 why would the fuel consumption be high and loud valve train noise come from the engine?
After you replace your head gasket your compression in that side will be higher, I highly recomend to anyone that has to replace a head gasket that they do BOTH sides. With all the electronic checks that happen in newer vehicles a difference in compression can cause confusion in the electronics. poor fuel mileage try changing o/2 sensor sometimes blown head gasket wrecks sensor and causes poor gas milage
A blown gasket can be repaired by replacing the gasket...if you are talking about the head gasket, then you have to remove the cylinder head from the engine block and replace the gasket that is inbetween them. Cracked heads generally have to be replaced because they are made of aluminum which cannot be repaired permanently once it is cracked.
A misfire on a cylinder is caused by either a bad spark plug, bad plug wire, burnt valve, oil fouled plug due to broken piston ring or busted piston, or a blown head gasket. Replace the plugs, then the wires, and if the condition still exists, have a compression test run. If you are loosing coolant then suspect a blown head gasket.
