Took to a Honda Only shop. Told me they were going to redo the head. This took 4 days. Once back, 5 days later wife tells me check oil light icomes on and off.
I checked the oil, added 4 quarts, called the shop back. Told me to do an oil consumption test! I called them back the next day and told them an oil consumption test was already done. My wife drove it 500 miles and used 4 quarts of oil. In addition white smoke was coming out of the tail pipe.
They took it in, and sent the head back to the shop. The shop tell them its the rings not the head. They get the head back, replace it, check everything out and tell me it is ready for pickup.
They say they replaced the PCV valve, and the oil consumption dissappeared.
However, there is still white bluish smoke still coming out the tail pipe. They say it will pass emissions inspection. They say it is the rings, and the car will run fine for a long time. BUT the car did not have the smoke before the timing belt snapped.
BUT I am not schooled in cars, I only know what I read or hear about.
Compression tests are fine, BUT the car is going thru 3 quarts of oil every 350 miles, eventually it may go unless the oil problem can be located.
The work that was done is fine,
How can it be checked to determine what is causing the oil to be used so fast? Is it simple? Is it expensive?
How can I reply to whomever replies to this question?
Do you

Hi iggy74,

To reply to whomever attended to you, use the "Post Reply " link and continue from there.

From the symptoom description, I believe the head job was not done well.

Either the valve guides were damaged together with the valves when the timing belt snapped or the valve seals are faulty.

The shop re-did their work to ensure it was done correctly. Remanufactured head shop says its the rings. All parts of the head was replaced. New valve seals were part of rebuild. Yet the oil consumption lingers, which wasn't there before the timing belt issue.
Does the engine need to go, to be rebuilt as the shop says? Are they missing anything?

If the head is confirmed to be fault free, then you would have to get the pistons out to check the rings.

There is a possiblity when the valves were damaged, they hit against the top of the piston and if the impact was great, the piston could have been damaged to cause the rings to stick. When the rings do not move freely, oil consumption would occur.

Under such circumstances, the engine would sound noisier than normal.

If the grey smoke occurs during idling, the more likely cause is the head. Get a second opinion if necessary.
