Guys i need your help, something went terribly wrong. I did all intake gaskets today along with OSV and new vanos fuel injectors today. I took the whole manyfold off, fuel rail etc. I swapped my old non-vanos fuel injectors to the vanos injectors (boch style 4 with all new gaskets filters etc). When i hooked everything back car run terryble (like a misfire) for a few seconds than died. I tried to start again and same thing only followed by sound similar to backfire.At that point i double checked the connectors and everything seemed ok. Also i took the maf to look in the intake and noticed when i opened the seconfary butterfly a litle bit of smoke came out of the intake manifold...At this point i left everything as is and waited for my mechanic to come. When we tried to start again the engine would just click...would not turn over.He checked everything out and thinks that gas filled up the cylinders...tommorow we ll be takin everything upart again and takin off the plugs to check for fuel. Could it get hydrolocked because of new injectors? Or did i forgot to connect something or have a major air leak? I am looking for any ideas guys please help me out.All parts are oem bmw.

Pull the plugs and try to turn the engine over. If HL, something will come out the holes.

sorry bro but one of two of the manifold gaskets is inside the INTAKE. Huge vaccum leak I would say, It happen to me. The engine sound was hard knocking with backfire and engine idle would not hold.. You should also be smelling gas right? ..I tried reving it but it would die quick. I had no clue as to why but calmed down and removed everything again...What I found was 1 of the manifold gaskets inside intake#4( backside of passenger engine ). 1 half of the profile gasket went inside the intake... I had to reuse 1 of my old 1`s because the new gasket got torn up......When I went to the M60 manifold I bought all new manifold gaskets. I tripled checked to make sure the gaskets were fllush on the intakes and NOT inside em....

Cazal please tell me i dont need a new motor....i dont care if i have to take the manifold apart again, i just hope nothing got damaged since the car doesnt even turn over now, yes definately had engine knocking. So tommorow morning will take it all apart again.

Your probably OK dude, just take it all apart, and take your time with the re-install of it all.
Lucky you, you don't have my problem lol.
No u don't stas
...once u pull everything aparr and reinstall everything back right(slowly) ur engine will be back to normal. It will run ruff for 10 minutes. Turn off engine a restart it. I remember like I was yesterday. Prior to finding out the gasket was inside the intake my engine wouldn't start either and when I tried to turn her over the engine sounded like death. It wouldn't idle period. Again make sure the gaskets are seated righ and make sure the vent tube is on right underneath
The extra gas in th intakes will mqke the initial start sound crappy but it will smooth out.

take the plugs out and crank the engine to get the gas out.
Once done (be sure battery is full) try again and listen for vacuum leaks
Have a technical question, don't send me a PM but post it on the board so others can benefit from it!
Ok took the manifold off again, the gaskets were fine, i did find oil between one of the glasses looking gaskets and the opening with the valves; i am taking the plugs out now. On the side noye i really dont like how the new injectors sit, i can turn them with a bit of force while they are connected not sure if thats ok.

Stas,
Everything is going to ok. The chances of an injector failing on the wide open position is very very very very rare.... Very rare. At best it would leak. As previously said, you probably just have a intake leak from a gasket or hose missing.
The injectors can move freely when freshly installed. Remeber they hold vacuum and not pressure inside the manifold, so it doesn't take much. Just be sure the fuel rail is bolted down properly to hold the injectors in place. It is ok if the spin in place, especially with all new seals.

Well my block cracked....found a big hole next to the starter in the motor , i guess time to look for new engine or call it quits and buy a corolla. I still want to know how could this happen, cause if i get a new motor i have lots of new parts for it, and dont wanna crack another block.So ye i guess this is becoming one of these convince me to keep my car threads....

Wtf?
I don't see how an intake upgrade could cause a cracked block. Something else must be afoot. I will send you a pm with my number. Let's talk.
John
Cracked block
Wtf? When I tried to start my car, like an idiot, I kept trying to make it hold idle for like 20-30 mins. I could of put money I ruined my engine they way it tried to start. Bang bang bang idle bang ...It was ridiculous the way I was trying...but it went back to smooth idling the next day...Cracked block for different fuel injectors? thats crazy. BTW was it your 740il or your 750iL that went bad?
S62 engine in ur future?

Wow what a bummer! I heat hearing about this stuff. Well If you were to buy an econo box it would still be more cash then it would be to just replace your motor...
Running on all 8 cylinders once again!
Sorry stas...
Basically if sounds like the engine hydrulic'd which caused the rod to break and that is what put a hole thru the block.
Sorry to hear this Stas.
Damn, sorry stas that sucks
Get a new engine rather than buying a POS...at least you know everything that's gone into your car.
Replacing the engine is still better than replacing the car.

Ok i am looking for a new motor asap if anyone knows about one around mass please let me know! Will most likely come pick up around rhode island new york etc if the price is right. I still wanna know how this happen so throw some ideas at me, the engine hand cranks to a certain point than stops , second cylinder is stuck from the driver back side. The big chunk came of the passenger side next to the starter.The thing that sucks most that this was and valve cover gaskets was the last project on my car. I mean i had zero issues with my car with 200k, my tranny has 60k and pretty much everything else possible got replaced.

How did this happen?
Not from an intake swap!?!?!?
Have any pics?

Man that's terrible I feel your pain man. Sounds like maybe something fell into your motor or something, or it was just some crazy coincidence.
here is some in your area, this may help you out?

Oh wow, sorry to hear this Stas
Does sound like a crazy coincidence...
the only way that could have happend is at least one injector is stuck open and filled a cylinder with gas, the force of not being able to compress the liquid broke a rod and cracked the block. DO NOT reuse those injectors unless you want it to happen again. There is NO WAY a vacuum leak will fill the cylinder(s) up with fuel flat out. get your money back on those peicers....
