Keep getting p0302 code

Im still gunna put the vct solenoid in once i get it. Then if that dont help itll go to the dealer. Just had to put car back together last night to put vette in the garage. Snow sucks. Im still going to replace the vct even though it looks fine. Thats how i gotta be at work also with jet engines. Even though a part looks fine it might not be fine and a plane just cant pull over and pop the hood and walk to a service station. So thats the mentality i have when working on anything

My sho also shares the garage with a vette. What’s even funnier, over 20 years ago I had an sho sharing the garage with a vette.

I got my vvt solenoid and i will install it tonite for the heck of it but i was also wondering what that real long bolt is. Going down the throttle body of the car. Gray i believe and marked i think. I had it out and reinstalled it. Is that like a idle control screw like my na6 miata has to override the computer?

[yaycandy]

Not my car. A image i found online and circled the bolt. I had that out before the issues got worse. Not sure what it does

 

[yaycandy]

Now i did figure something i think. I put my camera in the vacuum inlet of intake manifold behind throttle plate and fished it to the second cylinder. Then i got my seaform with a metal long bendy end on it. It took awhile but i got it right at intake valve. And it was misfiring the whole time. Until i sprayed seafoam. Ran real smooth with seafoam spraying over the 2nd cylinder. Mabye the fuel rail is clogged from e85 like right at the second cylinder but i dont know how it wouldnt effect others though. A thought. Ford told me no openings till december ha. Figure it myself

Are there any writeups on turbo removal? They both blow alot of oil out. I had just downpipes and removed the rest of my exhaust. They both blow oil out. O2 sensors looks like....i cant even describe it. So caked up they dont do anything. I wanted to order atp upgrades but i called livernois and they wont tune them without a fuel upgrade and torrie wont tune for them either. So i guess ill buy stock garrett remans

 

[luigisho]

what is considered a fuel upgrade? Just a higher volume pump or more? If it's just a pump I'd do that and get the turbos you want.

nevermind. just took a peek at retail price. ouch!

Yea its like 3k for turbos and probly another 2k for a fuel pump. I wouldnt do a turbo upgrade because as hard as the tranny shifts now with stock turbos and tune before. Id just consider a tranny upgrade. I see shift kits but itll have to be some custom work to make it handle over 600hp maybe. Lots of angles in it compared to rwd application. Lots of angles=1. Haha

Very little compression in cylinder 2. Both turbos blown. I blame ford. Didnt have those issues until the wastegate hose flew off. I guess no hose means max boost. I guess its engine time. I have livernois engine in my cart on there. They just wont ship it to me. May have to shipcar out to them

 

[SHOdded]

Ugly ending to this phase of the story The pcm monitors over and under boost conditions tho, so it would have popped a code if beyond tolerances. I dont think we saw such a code? Maybe the failure happened too quick to set a code? So I have no explanation for the lost compression, other than that is one of the more common scenarios in a failed 3.5EB. If we blame the oil, could be timing, could be the piston cooler squirters, could be anything.

I really dislike that open deck configuration. The Livernois build, with bigger turbos, is a great way to move forward.

 

[yaycandy]

210 compression on all cylinders but number 2. Number 2. Is 30-60. More on the 30 notch

Could be bad intake valve. Bad exhaust valve. Headgasket. Or worse a piston ring

 

[SHOdded]

That is a whopper of a difference. Usually a broken ring, but who knows in this specific case. No one has done a teardown yet to provide independent verification, too time consuming. Reliant on dealer assessment - cracked block, broken ring land, etc.

 

[yaycandy]

I did a wet and dry test and some other tests. I had to turn my brain on but i figured some stuff out. Every cylinder was over 210 except cylinder 2. The cylinders next to it matched the cylinders across from it. So headgasket is good. Also no issue with coolant. I did a wet test. Got about 50. Same as dry. So that tells me. Rotating is fine. Rings are fine. Its a valve. My oil blow by could be from sticking intake valve and oil from cams possibly leaking into it but im not sure if its possible or not on that head design. I pretty sure its not an exhaust valve because ive had a sticking open exhaust valve before and it was fireballs in the mufflersystem. Was cool but had to fix it on my bigblock. Im thinking the intake valve not sealing could be the issue. Im gunna tear intake manifold off and clean them instead of wasting money on intake sprays. I had the turbo intake pipes off. Its blows smoke out but not into intake. Maybe caused by cam oil leaking into cylinder from a not sealing valve. I looked at my turbos real good and saw no play in them or any leaking areas or anything, just rust. Intake valves looks horrible to me. Worth a shot.

 

[yaycandy]

Maybe something can be learned from this. Or close to this.
Kids dont unplug your spark plug cord on your bigblock with an hei system while holding the hood with your other hand while the engine is running. It can overcook your little noodle like it did to mine 4 years ago
