Head gasket I want to change the head gasket on my honda civic dx 91, any suggestions??? I

if the low pressure is between 2 adjacent cylinders, it will be cheaper to replace the head gasket

Replacing a head gasket is not a DIY job, unless the person has plenty of experience, knowledge, and the proper tools. The fact that a you would even ask, "how to replace 91 honda civic head gasket?", would indicate that you should not try to do that repair.

To replace a head gasket you must remove the intake manifold, exhaust manifold, valve train, and then the head. This is very involved and requires disconnecting lots of sensors and the ignition system. The head must then be checked to see if it is warped, or cracked, and repaired if necessary. You must then know how to put all this back together and torque all the bolts in the proper sequence. This takes training and skill which the average shade tree mechanic does not have.

If you are dead set on DIYing it, get a vehicle specific repair manual and dig in. Good luck China OBD2 car diagnostic tools wholesale on CareUCar

I believe that in '91 or '92 Honda switched from an analog (cable-driven) speedometer to a digital (sending unit/electronic head) version. Likely problem is the sending unit attached to the transmission. Try this website for a replacement and an image of the sending unit: http://www.carpartsdiscount.com/auto/parts/92/honda/civic/switches_sensors_and_senders/speedometer_impulse_sender.html?3593=89758

Good luck.

Fuel tank venting system is "stopped up" somewhere along the line (this is also called the Evaporative Emission Control System). Suggest taking it to a shop for a diagnosis.

Why would you change one that worked? Check connector for 12 volts and check for a broken ground connection

did you put the belt back on the camshaft correctly while removing the head off the block changing the head gasket? if you dint than timing is off... STOP everything and check make sure you put everything back in timing... if you did you may have to rotate dizzie back and forth to catch the correct timing while turning your engine, "Caution" all hondas' engine is interference engine which mean if you put the timing incorrect position you will damage your valves. its very important that you put the timing back in the correct position, if not you will damage your head and valves.

bro. what u need is a b18 swap.

Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.
