BullittBrock

So I have a 2001 mustang bullitt. Just passed 130,000km and if I let the car sit for a bit (duration of a red light) it blows a puff of blue smoke out the back. Sometimes very little sometimes a bit more. It's been doing this for quite a few months now and I've tried thickening up the oil but no change. And the weird thing is it uses no oil This is pretty low km for a problem with the seals I'd think.

I'm kinda confused by this any tips as to what it could be or what to do?????

Thnx for reading

I'm guessing the seals. You say it's low km, it could be a combination of km and age. Do a wet and dry compression test. That may give you some answers.

Best thing to do is to take it to a licensed mechanic for an evaluation of the problem.

Sound like valve seals to me

No idea on your blue smoke issue, but if you need some spelling pointers…..

How old are your spark plugs or plug wires? If one or more are fouled enough then there may not be enough spark at idle to ignite the fuel so it may be collecting in the cylinder and suddenly burning when you roll away. Or a partially clogged injector that doesn't allow enough fuel to enter until you begin to accelerate and the pressure increase causes the collected fuel to enter the cylinder all at once causing an inefficient combustion cycle. Blue smoke is almost always oil or fuel so if you aren't burning oil then it is more then likely a fuel delivery issue. The first do-it-yourself step is to check your plugs and wires. If one or more of your plugs are light grey or light brown then they are okay but if they resemble the colors or condition shown in the attached link then new plugs might save you a trip to the garage. Anyway good luck.

Was gonna say that you may need a tune up aswell, or fuel issues, if not, valve seals, or even rings.

What he said.

If the seals are worn, vacuum will draw a little oil past the seals .

If not plugs, have the compression tested, can do when changing plugs.
this will tell you about your valves or rings.
