Looking for help my 06 baja sport is drinking oil and smoking bad I took the engine out did the rings didn't fix it then did the valve seals still to no avail thanks for any help

Have you looked at the turbo? You could have a blown seal that’s leaking oil into the intake or the exhaust. 

Its naturaly aspirated no turbo but I did check the pcv system and replace all parts of it intake seams to be dry 

any smoke coming out the oil filler pipe?

It smokes a fair bit out of the oil filler but i didn't notice any blow by maybe a tiny bit at idle but goes away however the smoke goes up with rpm 

For testing, unplug the pcv hose to the intake and block off the port.  That way you can rule out pcv related oil consumption.  

Did you have pictures of the cylinder walls before replacing the rings?  If it was smooth and lost the crosshatching, chances are the new rings won't break in properly.  

Apologies, I thought all bajas were turbo for some reason. I’ve only ever seen one in person when I was in the states in 2009, even then that was in traffic on the Las Vegas strip so not an up close for a good look over it. 

I’m out of ideas. If the re-ring was done properly I can’t see where it would be potentially sucking oil in to be smokey and consume oil. 

We’re all rings replaced and were they gapped correctly?

Head Gasket blow-by?

With pcv disconeted still burns oil i let it run for several minutes incase of residual the cylinder walls were honed when when the rings were put in and the rings were gapped but it seemed like it only worked for 300 miles before starting to smoke bad I think Ill either tear it down and do rings again and measure everything to make sure its in speck or grab a junkyard short block to through in thanks you all for your ideas

Most are non turbo.

How many miles on the block? 

Leak down and compression tests?

Check the PCV valve system for blockage?  Seems like a long shot but if you're confident the valves and rings aren't it....

Was it burning oil before you replaced the rings?  After you replaced the rings did it burn less, more, the same, or can't tell? 

When rings were replaced were there any signs suggesting which cylinder was the culprit?

Did you replace all the rings?

There's only two ways for oil to enter the cylinder:  valves and rings.  Rings are most common

Finally solved it for anyone wondering it wasn't actually oil burning like we thought at all it somehow is getting brake fluid sucked in from the brake booster which I didn't even know was possible

So new Brake Master Cyclinder and Booster?

Yes that's the plan

That sure is unusual!  How does that work? I don't see a physical connection between the vacuum lines on the booster, and the brake-fluid system.

EDIT (2 weeks later): I now see how this must have happened: the brake master-cylinder is mounted on the front of the vacuum-booster, with the operating rod of the cylinder extending into the booster. Hydraulic-oil must have leaked past the rod-seal, and into the brake-booster; and from there, a vacuum hose would have sucked the hydraulic-oil into the intake-manifold of the engine. Bingo, oil burning-off in the exhaust!

That's wild.  Glad you figured it out.
