Default Cars blowing white-ish blue smoke-Help Me Please

So i discovered today that my cars blowing white-ish blue smoke out of the right exhaust tip. Its only under harder acceleration, not idle or speeding up slowly. Any guess at what this could be from? some things i checked was the coolant, theres no oil visible in it however it is low, i've also never noticed my oil level dropping however if i get on my car in WOT from about 30-90mph i will smell a little oil but nothing extreme, also the car has 130,000 miles and i believe atleast one of my catalitic converters is "going" bad due to my car smelling like "burnt cats" under acceraltion, not really sure what that smells like just what i've been told when cruizing with a friend in a car behind me

Anybody know what could be causing the smoke?
How can i fix this and what would it cost/involve me doing, if possible i rather do the work myself?
What could happen if problem is ignored, like will there be other damage to engine?

How much smoke? Most engines will let a little smoke out under WOT but it shouldn't be that noticeable.

It is definitely going to be something internal no matter what it is, could be something in the head or piston ring(s) but either way not cheap

First change the PCV valve and make sure its not just oil blowby, after that if it continues it could be worn out rings or bad valve seals which would be time to rebuild.

+1 with Uber.
You might want to change the PCV valve and possibly add a "catch can" between the PVC valve & intake fitting. At WOT you may be sucking oil thru/past the PVC valve.
This is an inexpensive thing to try.

Depending on where the intake end of the hose is plugged in could explain why the smoke is only on one bank.
Start with the easy stuff before assuming it is in need of major engine work, you just might get lucky.

Valve seals/guides are "usually" both banks equally, as well as heavy blow-by.
Head gasket issues are one bank.
Broken rings are one bank.

Doing a compression test will tell you a lot, and maybe eliminate a lot of possible issues.

to rule out worn rings do a compression check....real easy. just make sure your weakest cylinder is within 25% of you highest pressure reading. if it is then your doing good there. i mean 130k isn't that high mileage, but its when things start to get alil loosey goosy

Thank you very much everyone, I took you guys advise and changed the PVC valve yesterday and will check for smoke in an hour or two and if it's not that then I'm going 5.4 anybody know if the stock auto tranny is a direct bolt on

As others have said, if it's just a little blow by, a catch can would remedy that. Our billet catch can is only $89 with a Lifetime Guarantee if you use the mf.com discount, and it's very effective at catching the oil vapor. http://www.uprproducts.com/mustang-b...erator-79.html My '06 GT was occasionally puffing smoke at startup, but that went away after I installed a UPR catch can on it.

Regarding the 4.6/5.4 swap, I believe the tranny bolts on the same, but I'm not positive.

I am having a similar issue with my 06 GT so please keep posting updates. Light blue smoke at high RPMs WOT. Have also heard ticking sound at the same time, not always though?

You have a leaking injector. Change out the bad one soon, running fuel/oil in crankcase motor wont get lubrication properly and boom new motor time.
