Good day - My car is a 1996 Suzuki JLX, also known as a sidekick - 2 door convertible. The car started jerking while driving and I initially thought it needed an new fuel filter. I replaced the filter and cleaned the carburetor but the problem still persisted. The car also overheats so I decided to check the oil and found that it had a milky colour. I also had to fill water in the water tank everyday. I assume the head gasket needs replacing and skimming done on the block. Please advise how much this repair will cost.
