just wondering why my 2000 gsr burns oil seem to burn a quarter of oil every week or two

 

You blowing smoke at high RPM's?

I would assume that oil loss like that can be attributed to blown piston rings. I was in the same boat and was going through about the same amount as you are and it turned out to be toasted piston rings.

Here is a post about my delightful experience replacing the piston rings: https://www.honda-acura.net/forums/s...d.php?t=177478

 

First things first, what oil are you using? These motors burn oil naturally, just not to that extreme. A quart a week (depending on mileage) is a ton.

The wrong formulation in these cars can cause serious oil consumption as you are describing.

 

i have the same problem, and its your piston rings and/or valves. you need to get into that engine and replace the piston rings, and have a valve job done somewhere. you also need to replace the valve seals. if you dont feel like doing it yourself (i dont recommend it, since you probably need the cylinder walls honed) find a machine shop to do it for you. of if you dont want to spend the hundreds of dollars to have it done, its always cheaper to just keep putting oil in it. nothing will come bad of it in the short run, but u need to get it fixed if you plan on keeping the car and/or engine. just dont drive it too hard or else the problem may worsen.

btw, my car is burning 2 quarts every 2-3 weeks, i feel your pain! i am fixing the problem in the mechanic program i'm in. it should be fun!

 

:werd:

Especially if the car is taken into VTEC a lot.

 

are you hitting vtec everytime you shift? thats alot of oil.

 

The valve stem seals will only leak during vacuum conditions. Yes, vtec burns oil, but with the abnormally large amount being burned, I tend to believe something is wrong.

A piston ring install isn't that hard, it is just very labor intensive. The head needs to be pulled, oil pan dropped, and the pistons pushed out to access the rings. Honing can be done with the block in the car with a drill and the proper stones (400 grit) as long as care is taken not to hit the crank and thoroughly clean the bores afterwards. It took me 10 hours working by myself to do it in my garage, so it isn't the end of the world.

The danger of not fixing the problem is that the oil consumption will starve the engine of oil if the oil level is not properly maintained. You can also kiss your catalytic converter goodbye if you let it burn too long.
