Just about every 2000 miles of driving my oil pressure drops dramatically, so i check the oil level and i find out that its below the lower line on the dip stick... i have checked for leaks everywhere and i still havent found any leaks... Does this mean that the piston rings are bad??? When i swapped in my DOHC ZC, i rebuilt it with all new rings, gaskets, bearings and more.. the engine has about 30k miles since the rebuilt... Should i change the piston rings?? or is there another reason why the engine is burning oil??
any help is appreciated...
thanks

 

Check your PCV valve....as b17gsr mentionned in the past...you can suck quite allot of oil through it.

Are you puffing?

 

is it smoking??

 

the only way i know of to test the rings is compression testing. doing a dry run first and then a wet, a tbsp of oil in the cylinder, and that should do it.

 

Even then its total BS...I'm pissing oil out of my rings and I have perfect compression........its ghey....leakdown is a bit more accurate.

 

I dont really see any smoke coming out... i guess ill do a compression and leak test too..
thanks
any more info??

 

try dumping a bit of oil in the cylinder to see if that bumps compression up dramatically. If it does, it's rings. Leak down test will tell you if you have a blown headgasket or leaking valve seals.

 

a leak down test will only test your compression rings..

If you buring oil and you think its your rings it would be your oil rings.

Or it could be your Valve stem seals.

Or your PCV

 

what if there's oil on your plugs, does that necessarily mean its your rings? could it be bad spark plug gasket deals?

i don't have smoke, my compression is fine, i'm not losing oil, but i found some oil
on my plugs..hmmmmm any ideas?
