Bad rear seal how to change

No hose. You may have a rear main seal crank seal leaking

If they are the same engine they will.

Main Relay. 9 times out of 10, that's the problem.
Notorious to go bad on these cars. Its behind the dash, above the drivers foot well

Are you sure you have correct timing? its definetly a fule problem, if timing is good then turn your key to the on position and try to listin for the fule pump to prime. While the key is in on position go to fuel rail, there is a valve on fule rail called sharader valve. Get a small screw driver and press valve in to check if car has fule pressure. if pressure is present then it is incorrect timing or possible bad cam sensor.

bluish is oil burning,if your car is smiking worse going up a hill that is piston rings,if you notice it worse coasting down a hill that is valve seals,but have you tried replacing the PCV valve yet,this lets the engine breath like you and me

you have a blown seal or seals its an internal problem check your valve seals and your piston rings hope it helps im a honda guy so let me know if you have any other questions i rip apart honda motors all the time

the fuel level sensor in the gas tank needs to be replaced easy way is a new fuel pump assembly

change the struts and have a 4 wheel alignment done

I would suggest you check your drivebelt/fanbelt tension and waterpump.

wow. a lot of bad information on this site. Refer to a manual for the proper torque sequence. The civic I believe is a two step torque procedure. First 22 ft lbs, than 53 ft lbs.
