G'day folks, I have a 12/03 civic sedan, manual with the D17Z1 engine. At 100000km it started to use oil. Now at 140k it uses 500ml of oil every 1000km. Honda are playing with me. Does anybody else have an oil consumption problem? I have a list of other problems that you may be able to help with, hopefully. Thanx :thumbdwn:
Did you always drive off as soon as you started the engine? Did you use heavy throttle before the temperature needle reached the middle?
Yes and no. This day and age you do not need to warm the engine up prior to driving off.
Do you see an oil puddle on the driveway where you park the car?
Sounds like your engine may have an oil leak, its quite a common problem with older engines.
Check for oil leaks around the CAM seals, rocker cover seal, head gasket, oil filter, and oil sump.
EFI engines can drive straight away, but its not recommened. If you do drive off when its still cold, you will wear the engine down faster resulting in the engine losing compression and blowing grey smoke sooner.Quote:

also maybe coming from your dizzy seal, rear main, crank seal as well.
lots of variables.
Head Gasket ftmfw :pQuote:

There is no difference between the internals of an old carbie engine and a new EFI model (apart from manufacturing tolerances) so they can still be damaged by "abusing" a cold engine.
Do you service the vehicle yourself? do you know what oil is being used in your engine? Engines can use vast amounts of oil if the wrong oil is used!
Other than that an oil leak could be the cause, but it would need to be a bad one to be leaking 500mls of oil every 1000kms! Has the car been checked at a workshop?
Firstly, I am a mechanic by trade, because of warranty reasons, the car has been serviced at dealers. Here are the facts. The engine does not leak a drop of oil. Two plugs are gumming up. The pcv has been changed to no benefit. The car is not abused at all, and it makes no difference if you drive off straight away. Thanx.
Well, if two plugs are filthy you obviously have an internal problem. Do you know what number plugs are gummed??
Have you done a compression test??? Does the vehicle blow smoke when first starting of a morning or when revving it out???
are the other problems you mentioned you have engine related???
Plugs 2 & 4. Honda have done a compression test, and it was OK. Does not blow any smoke at any time. One other problem is ECU related. On deceleration with a slightly open throttle, as you do in traffic and going down a slight decline, the car surges and jerks badly. Honda say it's a characteristic of the car and we should adjust our driving. What a load of crap. I feel it is emmision control related. It's only found in manuals. Has anyone else come across this phenomenon? Thanx.
Replace those plugs with copper ones (as they will get gummed up again if the problem is not fixed). Then get a compression test done on your car.Quote:
