So here's the case. I already replace every suspicious spots with new oem gasket and new valve seal too. Cleaned up the engine bay to a point that i'm willing to lick it, refill new oil, drove it for a good couple days, then there are no trait of "leaks" at all. but the dipstick still read low somehow! I did a comp test and a leak down test the results are all good so that I excluded the possibility of bad bad piston rings. Any insight?? It's a waste of money to buy oil between 3000 miles regular period!

 

pcv valve
check it

 

^yes check the pcv valve.
There is a chance your piston rings can be stuck which wont allow the rings to move freely thus causing consumption. You can do a few things to loose these stuck rings
-mmo piston soak or some other piston cleaner
-auto rx
-in 2nd gear from about 3-4k rpms gun it to redline and let it engine break back down to about 5k and repeat 2-3x more times. this can potentially loosen all that carbon in your rings. I actually did this and after 4k miles on the oil change, i dumped the oil and cut opened the oil filter and found small bits of carbon in the filter element. I know it was carbon because i rubbed it against white paper and it powdered up like chalk does.

If your control rings are worn, only fix is a rebuild or new block. Hondas usually have a problem with their oil control rings...compression test wont tell you this, the dip stick does.

How much are you burning? my 01 ls with 130k miles burns about .5 quarts in 5-6k miles.

 

yea, oil control rings is another possibility. are you actually burning oil though? you have blue smoke?
i'd check the pcv first, since it's easy enough to do.
at idle, pinch off the line between the intake manifold and pcv valve. if you don't hear the pcv valve click, replace it

 

Thx for all the replies Ima do these tomorow and come back with updates!
