When I purchased my 07 Tl-S it came with rv6 pcd and I noticed blue smoke coming out the exhaust while taking off in 1st gear and also if there car is on idle some blue smoke comes out so is it normal for this to happened with pcd?

Also my car has an xlr8 j pipe so idk if that makes a difference.

Exhaust Smoke Color Diagnosis: Blue, Black, or White?

I've seen cars with PCD but no blue smoke so I would say not normal.

Don' know if it still has the downstream cat, but If the cats were installed, no smoke.

Blue smoke generally means you need new valve stem seals.

Engine is burning oil not related to the PCDs. I would check compression.

so if I replace that part that would fixed it and not smoke blue anymore?

Well, since blue smoke is a result of burning oil, it could be a variety of components. Valve seals are one, piston rings are another possible culprit.

Are you noticing your oil level dropping off over time? If not, I wouldn't worry about it. My 2009 Honda Pilot has 200K+ miles and spits out a bit of blue smoke when I start it after sitting for a few days. Yet the oil level never noticeably drops and it runs fine. If that's the case, just leave it alone. However, if your oil level is dropping significantly, you may want to have it repaired. Problem is, it's not a cheap repair. Probably well over $1000 to rip the engine apart and replace seals and rings.

I called the Acura dealer and they told me the tl don't have stem seals only exhaust and intake seals 6x per cylinder

i haven't checked, I just did an oil change so I'll keep monitoring the oil and it barely smokes, only a small amount when I start the car and when I take off from a dead stop and not every time as well and then it doesn't smoke anymore while driving.

I really wouldn't sweat it much then. It's not entirely abnormal for an older motor to allow a little oil between seals.

Your dealer doesn't know what they are talking about. Here look at number 3 and 4 it says Valve stem seal. There is a valve stem seal for every valve.
