i own a repair shop,,in Tennessee,and i repair a lot of Honda,s and from what you have described to me,,it could be the water pump,or the thermostat,,to find and change the thermostat you just follow the top radiator hose down to the motor,and there you.ll see a housing that it is attached to,and two or three bolts that hold it to the engine,remove them,and the thermostat is under the housing,,be sure and drain some of the coolant from it or it will run out when you remove the housing,also be sure and clean all the old gasket off,and put a new one one with the new thermostat and make sure you replace the thermostat in like the old one was,and don't over tighten the bolts that hold the housing on,,and re-fill the system,and your done,,good luck,i hope this help,s.
How can be sure it isn't leaking through the head gasket? If the car is leaking alot but there is no oil drips on your drive the leak is internal, most likely the head gasket. How long have you had the car? Some cars use more oil than others, it may be that this car uses more oil than other, unless you know that the car didn't use as much oil previously.
nothing much just lotsx of work
A Head Gasket does not make any noise. Remove the Head to replace it. It will be where the head bolts to the Block.
I believe it is 90 days. If your vehicle passed smog, you can always lower your price and make a deal with the buyer to smog the vehicle themself. It is about $20-$80 to do regular smog.
It depends on what work was performed on the 100k service and the reason it failed the initial smog test , you just don't know if it will pass until you have it retested , unfortunately the consumer has no choice .
most places will run a pretest for you if you ask or find a shop that has access to an emissions analyzer who can check it before you actually have it retested .
I cannot give you ideas on what to check because you did not mention what was done on the service why the test center failed your particular vehicle . You should receive a report from the testing facility stating why your vehicle failed and a good tech can interpret the report and advise you what should be checked .
I have found several BMW's that have come into my shop which have failed a smog test due to a small vacuum leak at the throttle body,which is something beyond the typical 100k service
