It will most likely be the valve cover gasket

Well I just did my valve cover gasket about a week and a half ago is not that hard for some it is of your a dyier guy you could tackle this job just check if your dropping oil on your left side of your engine passenger side the smoke comes from the oil dropping in the exhaust causing white smoke to come out just check your oil regularly to make sure you good on oil if your not dropping to much you can roll like that for a while until you replace it

DIY - not too bad

I would allow about 3 hours and read over the instructions and required tools before you begin. It will not be that hard and will save you a lot of money.

This thread (first picture) shows exactly the leak that I was having:

If you are leaking oil, it will not be good for your engine, so you don't want to let this go too long.

Good luck.

Has to be VCG.
Order VCG and 15 rubber grommets.
I'd advice not to use victor reinz gasket, I had to re-do the VCG in 4 months after I replaced it with victor reinz. I'd rather order elring or OEM gasket.

OP, I'd prefer you to use a torque wrench if you are doing this kind of job for the first time. The studs are easy to break if you over-torque them.
7~8 ft lbs of torque is what is needed to wrench those cap nuts.

If not a torque wrench, then once its snug hand tight, just a quarter turn is all it takes to get to that kind torque.

Good luck.
Its an easy job(around 3 hours slowly), but careful not to drop anything inside the engine.
Also, if you want to do the spark plugs its a good time.

Tip: warm up the engine a little(not fully warm, it will burn your fingers). It helps to remove the old gasket easily, as heat makes it a little soft.

OK thanks for the tip!

I did get the VCG's.. I was told by a buddy of mine as well he did say get those VCG's or your going to be visiting the engine bay in 4-6 months to redo what you have did..

there is one thing that I was wondering was the silicon gasket seal stuff.. what brand so I get and use? I see they have the high temp ones and there are others that are high temp and permanate versions.. Im just not sure what is a good one to use...

and yes I have that in mind to change the spark plugs but not sure which one would be good to use...

bosch +4 or
NGKs...

This may sound crazy but double check it is the vcg. I had white smoke coming from back of engine but could not see oil on exhaust. But i changed it assuming it was that, but it still did the smoking.

The crazy thing is, it was actually my gearbox pan. It was leaking slightly from a hole in it, and when i drove it threw the oil backwards onto the exhaust about midway beneath the car. The smoke however travelled along the exhaust then to the front and out the engine bay when i stopped moving. Why i saw no smoke out the side or back of the car was the strangest thing. The smoke seemed to just follow along the exhaust as if it was attracted to it.

If it is the vcg its a real easy job to be honest just take your time.

Plugs- i went for the ngk iridium on my 330

Sealant - here in the uk i just went to motor factors and asked for correct flexible gasket sealant. It was red stuff i can remember that much!
