Hi guys, so we have a 2003 Honda Civic LX, with ~146k miles, runs like a champ. Had the car since 60k, now it's consuming oil, not sure where it's going though? Have to add almost 1 quart after every 500 or so miles. No smoke, no CEL and nothing. Just a bit background:
We replaced timing belt 3 years ago and somehow belt jumped and damaged the valves, ordered a replacement head from ebay and put everything back together. Then it started to leak oil from one of the seal in the cylinder head(o-ring). We fixed it and now no more leaks and it doesn't drip any oil either, but still consuming oil?
Where should we start to take care of it? So far we have used 5W20, occasionally 5W30, mixed with 5W20 in it.
Should we try to switch to a thicker oil or any known places to look for oil loss? I have 10W40 laying around, so as Shell Rotella 15W40.
Car is 100% stock, thanks for any of your help and input.
