If you remove the oil cap to check, make sure the oil is over 185*F. Before this "smoke" one may see will be condensation burning off. What you see is steam mixed with some oil. It should go away once its up to temp. If you see darker and almost bluish smoke always puffing out then thats an indication that it is oil. Also oil consumtion between oil changes will verify this.
Actually, it gets a lot worse once the car is warmed up. It barely smokes at all when you first start it, but gets worse as it gets warmer.... The fumes are pretty bad, especially if I'm stopped at a light. So yes, I could go ahead and do the pcv system, but I'm taking it back to the builder to do that as well (he took the one that was on there off when he changed cams So, I figure he can do that while he is figuring out where the smoke is coming from...
If you install the pcv back in the car,you will create vacuum. That how is works.
You need to do that my friend,before you spend dollars going in a different direction.
The pcv once it's connected to the TB, will vacuum the engine crank case gas and introduce them to the fresh air intake at the TB..
To me this is a first to do.
I would had done that in a couple of hours taking my time and am an old guy.
First, the builder is a young guy... One of the reasons that I was surprised he took such an old school approach... On the other hand, I AM an old guy... 45 actually, so I've been around engines and hot rods a long time myself. I've built my own old school carbed 350's for many cars, but know little of these modern "computer controlled" fuel injected machines. That being said, the builder and I have resolved that he will do the pcv system (LS1 to LS6 conversion style), take a look at the plugs to assess current cylinder status and then we'll see where the engine is from there. However, I now am having "service active handling" and other engine codes coming up (some I'm told point to a "maf sensor failure" according to my tranny guy who is going through my tranny for the 3rd time to make sure it's okay as I've also been having tcc problems with lockup. So....now I'm having a whold host of issues and the engine is running like crap and smoking like a "carburetor car with a stuck choke" ....again, according to the tranny guy.... So, once the tranny is cleared, it's back to the builder for the rest and to figure out what the hell is going on. Of course, I wasn't having any of these issues before the recent engine work (bigger cam, head work for bad valve guides) and tune either. Oddly, if it's worth mentioning..when the builder first got the engine back in the car, he couldn't get it to fire over and had, apparently, multiple electrical issues with the right firing bank and a ground somewhere... I'm wondering if I don't still have an issue there as well.. Who knows?? I'm about ready to demand my money back from everyone that has worked on this damned car and start from scratch again. If it's not fixed after this next round of "repairs"...that's exactly what I'm going to do. I'm tired of people pissing down my back and trying to tell me it's raining! If I hear "everything is normal" one more time, I'm gonna go postal! Anyway, I'll keep you guys up to date as more info becomes available. Sucks as it has always been a dream of mine to have a nice Corvette, but it is rapidly becoming a nightmare instead.
Sounds like mostly tuning issues. All those engine mods require a lot of ecu tuning including for the trans. Lockup and and trans line pressure all are controlled by the ecu. In fact, my old ecu got battery acid on it and messed it up. I kept breaking the input drum in my trans and couldnt figure out why. Well the ecu was overpressurizing the line (over 300psi) casing the drum to break at the lugs. I replaced the ecu and no more issues. Point is you have to look at everything sometimes that can cause a problem in a specific area with these cars.
Not blaming the car at all..... Definitely the people I've got working on it with the issues. Unfortunately, I don't have a lot of options here in Oklahoma and these guys were the most highly recommended that I could find. It is what it is...

I'm hoping it's something stupid and simple like that.... The trouble is getting people to take the time to find it. In their eyes, they already got paid and it's not making them any more money....In my eyes, too bad...you should have done it right the first time and not my problem. My tranny guy is going to tear the thing apart again and try to find the "problem", but he's saying it's tuning/engine issues causing the problems and my tuner/builder blamed the transmission builder. Next, I'm going to sit them both down in the same place and let them hash it out. My tranny guy is going to let me "inspect" the components on the bench while they are out and I plan on inviting my engine guy to look at them as well.... This way, he'll either see what's going on with it..or if it's fine, he can't blame the tranny anymore, so it's on to something else. I'm just frustrated because it seems to me that it shouldn't be this hard to get people to earn the money they so freely take and get good/careful work. I'm a nurse and I don't have the luxury of slacking on my job like that. If I approached patient care the way these mechanics approach my car, somebody could die. Sorry for the rant, but as I said....really frustrated.
