eating oil!!

Well i have been trying to find the reason why my CB is eating a quart of oil every five hundred miles. My compression seems fine and i can not find any leaks so i was going to try to put new valve seals. What do you think about superteck valve seals or should i just go OEM? Oh i what other thing can cause my motor to go through that much oil? Thanks

if you have ruled out an external engine leak, it can be burning in the cylinders. This would be caused by worn piston rings or, I think, poor or burnt valve seals .

It could also be due to leaky spark plug tube seals. Check to see if your plugs are covered in oil. ALWAYS investigate simple solutions before jumping to more complicated and expensive conclusions!

have you messed with the oil filter at all recently? i actually found mine to not be so tight and its reduced the comsumption a good bit. also i have replaced my tube seals but it didnt work so i think i have something else wrong. possible warped valve cover or something.

Yea deever that is all new with my a6 cam swap. Do you think those valve seals will work or go with oem ones? And then if that is not the problem think it will be the rings even thou it is holding compression.

I've never done valve seals, so I can't say from experience... However, OEM is always the best choice in most cases.

If the valve seals were the issue blue smoke would be coming out the tail pipe...

I'm getting around 155 per cylinder +- 10 psi, I am not getting any smoke out of tail pipe. So now I don't know what to try just want it not to eat or burn any more oil.

Perform a leak down test?Compression doesn't seem that bad off, but a leak down will tell you far more.Check main seals?I think you'd see an oil leak if its losing that much.
