Default Smoke ?

Well Guys I've finally got her running and on somewhat of a tune. The tune is OK but not a 100% but at least it doesn't have any knock. She has 2,200 miles on her and I have one issue.

The heads have new valve guides along with a mild port job. Motor was making a lot of noise last time I wrote inside the cabin but not outside. What I found to be the cause was when I put on the intercooler I smashed the aftermarket fuel lines onto the dog bone which transmitted the sound into the frame of the car and into the passenger cabin. Pull off the intercooler and wrapped the lines in a heat blanket and noise went away.

Back to the issue, Here's the deal. When I drive her around town and crank her I see no smoke, none not even in the morning. But I've noticed a couple of times out of no where a puff of smoke at start up. It lonely happens after I get on it real hard with a full amount of boost thru every gear. I'm running 24lbs of boost and was wanting to know could there be a reason she smokes at start up after she's ran hard ? I've only noticed it twice but then again I've only got on her a couple of times hard.
I thought maybe it's pushing oil at high boost into somewhere it's not suppose to be ?

Dnorton, glad you found your noise. I dont know about your issue, but I personally wouldnt be overly concerned about a puff of smoke after a day of hard running. If it was all the time, I'd be concerned. If it persists maybe you should run a catch can vs. the AOS. (apologies if you have one too and I didnt see it in the pic)

jdmforlife, perhaps you have an injector that is stuck open

I'd say its the grimmspeed aos not being worth a damn. There is not enough space to allow for proper speration to occur. I had a mild puff after running my car hard one day and I found a kinked line coming off of the turbo inlet to my aos. trimmed the extra slack that originally pinched the line and I have nothing anymore.

To keep a clean thread, you should start your own.

White and I can smell a hint of oil. It's wired that it doesn't happen all the time. They only thing that seems to be common was I've noticed it after hard driving, But not always.
You guys have been great helping me with all the hard questions I've had with this build and there's no way I could have done it without a lot of you. I wish there was some way I could repay you guys. I wish you were local so I could buy you a cup of coffee or whatever.
This question I assume is a tough one since it doesn't happen all the time. Tomorrow morning I plan on doing a compression test. That brings up another question, Should I try to warm up the engine a little before talking the readings ? This might be hard to do since my hands are tight as it is when removing the plugs and installing the tester.

I forgot to answer the question about the GrimmSpeed, Yes sir I have one and a chance to buy a Crawford for a good price. Do you guys think it's worth the money to get rid of my GS and purchase the Crawford ?

always do a compression test at full operating temp. remove all spark plugs while testing. unplug the crank sensor. and keep the throttle plate wide open while cranking by holding your foot to the floor. and make sure you do them all even. I count to 5 strokes when i do it.

and yes the crawford is better than that grimmspeed aos thing. seriously who wants to put oil that has mixed with condensation and gotten all nasty back into their oil.

Thanks Guys, I guess I'll have to figure how to get it warm but cool enough to remove the spark plugs.

I bought a Crawford AOS today and plan on installing it when I do the compression test.

Do it on a cold motor. The readings will be different but still uniform if you understand what I'm saying. Also, a leak down test would be good. Smoke is not good in any way. I assume the turbo is fresh so that's probably not the issue. Could he valve guide seal. Is there any oil in the exhaust ports when you remove exhaust manifold? Either way you shouldn't need an aos at that power level and boost to stop smoke.

^^^^ I feel the issue is what they guys in the thread say it is. I went and did a bunch of researching and if you search Grimm Speed VS Crawford you too will see the very same. My car does the very same thing they are writing about in that thread. Easy enough to find out. I purchased a Crawford yesterday and at the moment I installing it. After a few test I'll know if that was the issue.
The very first thing I though about was valve guides but since I just had then all replaced with seals and since it only puff a little smoke after I drove the crap out of it I dismissed that idea.

The Crawford puts everything back into the oil as well. I have a Tigwerks can made in the same style but with a petcock on the bottom, and the crap that I drain out is nasty. Fuel condensation, sludge...
