Would really love to see any updates about this engine, car, track vids, pics, etc. I used to live for this thread.
Hey boys (Happy 4th of July!),
So I'm sorry I haven't posted in a while. I did run the car on track back in March. The CJ monoblade kept limping and had a minor excursion into the tire wall (cuz of said limp) and needed a fender and door replaced (it happens), but haven't run the car since then for a few reasons. One of them is getting blind sided with work (which is good because I've now paid off said motor) and two, developed a nagging tendonitus in my shoulder. Soooooo.......lol......nothing juicy. BUT!
The motor was fantastic on track! It pulled so much harder than the stock motor that I was pushed back in my seat and said "Wow" in my head. And I was already condition to a tuned up stock motor. The difference was THAT much. Almost scary.
I'm prepping the car for mid July run. But I probably won't be pushing it too much since a lot of setup changes.
QUESTION: So right now, there is a good amount of smoke spewing out from the catch can when the car is warming up. The shop said its normal blow by. It _does_ seem to subside when the car warms. Just wanted to get opinions on that. Probably the rings are gapped for heat expansion at WOT? I know nothing about this.
Anyway, here's a video of a walk around from March and a couple looks at the car now. It's actually back at rev auto for a tune update for the SCJ TB and possible swap to the GT500 dual blade.

New fiber vented fender here (sorry for big pic, can't seem to resize them in a post).

It's probably blow by from rings not seated yet..
Not seated because the engine is just warming up? Or not seated because the motor is just breaking in still?
In other words, the rings seat after it warms up?
New engine, however its also possible the blow by when cold is due to the low tension rings they are using, or maybe also the super thin ring setup, its one of the tricks of the road race trade that you run low tension rings and gain HP on a NA engine setup careful to make sure there is zero blow by when up to temperature that can cause detonation. I highly doubt the rings are on upside down, or that the gaps were wrong and something fractured, or they didn't hone the cylinders correctly, etc.. I'd bet its designed in..
Ask Livernois they should be able to tell you instantly if its part of the design, if not, time for a tear down again.
PS. Total seal recommends break in with dyno oil only then change to synthetic oil after 2000 miles.
Edit: I just read this from your earlier posts about the pistons:
"Thinner Ring Pack for Reduced Friction"
That's probably what is causing it.

Thanks for the info man.
Yeah. I emailed them but they're on vaca. Waiting to hear back.
But let's assume it's not "a feature".
What would be the test? Compression test? The dyno will show detonation right?
The ECU will throw a wrench if there's real problem too right?

Leak down test. 3% or less is typical.
Stock boss brembo calipers. SS lines. GT500 brake booster. 302r ABS. Girodisc rotors. Hawk 70/60 pads. Castrol SRF.
It's a beast system. Just ask pufferfish who rode shotgun once last year.

Full VTA crankcases will also smoke a little as opposed to one where a vacuum is applied to the crankcase. The vacuum just helps the piston rings seat a little quicker / easier, but with the amount of rpm / hp / and heat you're running, it is almost guaranteed to be a ring gap with some expansion room built in.

Car sounds amazing Darren!
I am going to go with twistedneck on this one. I believe that with the rings and forged pistons it will create a little bit more blowby than we would be used to with the stock engine. Did Livernois ever get back with you?
Also, your cam drive kit came out
http://fordperformanceracingparts.com/parts/part_details.asp?PartKeyField=24693
$416.90 from Tasca and it comes with the Boss 302 tensioners, not the 2015 as confirmed by Steve just so there isn't any confusion.

Thanks man. Yeah, I have the kit, but had to source the parts separately and paid twice as much back then. It's a great deal from tasca though.
The shop confirmed the motor is all good other than a bad O2 sensor (oddly no engine light). The blow by makes sense, but I'm a newb compared to you guys on this topic and when I see smoke billowing out from my hood, my first reaction is....WTF....lol
Trufiber
No cracks so far. Work well.
Another topic coming up with the motor (which is doing well). The excessive blow by. It's been suggested to me to put a 3 vane Vac pump (e.g. Moroso) on. Moroso has a really nice kit but it lacks a mounting bracket for coyote motors. Has anyone dealt with this before, have any recommendations? Another person at the track suggested using bigger AN lines from the valvetrain to the catch can so it doesn't choke the motor not dispensing the blow by fast enough.
