Completed the swap, finally got the car to start and run, but after i took it for a spin on saturday, it came back rough idling and smoking white. But it's not a continuous stream of white smoke, it comes out in bursts and it was also shooting raw gas out the exhaust!!!

Car was working perfect before when we had it jus idling.

I need to know what i need to check and what could be the problem??? checked oil, water and transmission levels and all were good. Also had problems with the transmission which i will discuss after.

Car sounds like it misfiring but haven't got a scanner on it to actually tell. Service engine light on because of CAN,TCS and Evap problems so i can't use that as a reference.

I haven't hooked up the FPR to the return line as yet so right now i returnless and i using the stock 2.0 pump, not sure if it adequate or not. The one time i floored it it died on me and RPM never rose back to over 3000RPM like it starving for gas, probably because the tank was empty as it ran out of gas.

 

you know. i am having the same problem here and no one is able to help me. let me know if you find anything though, because this has been bugging me since my swap half year ago.
my exhaust smoke is only there on initial warm up though, after driving for a good 5 mins, it goes away.

 

I have smoke on intial start up to sometimes, it randomly does it
.

 

Your maf might be a problem. So you don't have a fpr on the engine?

 

Your dumping raw fuel(ubber rich) which indicates your injectors may be stuck open or the seals may be bad.
My brothers max had the same problem.It would poor raw fuel out the tail pipe till the cel would blink, but the smoke was minimal once the car warmed up. It ended up being 1 dead injector and 1 bad injector seal.Good thing I had some extras hanging around
Do a ohm check on all injectors first.And ask your installer wtf he screw up this time.lol I hope you didnt melt your cats.

 

I was also told the thing about the injectors stuck open. I was told to get them checked(serviced) and change my plugs and see if that helps. i really hope i don't have to go into the engine as that is an additional expense i not up to right now. I don't believe it's oil as it not smelling like oil, it smelling like gas and strong....

I will refer to the FSM to do the test u stated above(OHM).

So no one thinks its valve seals???

 

CONGRATULATIONS!!

Could be running in safe-mode also, are your cooling fans on high all the time?



That could be the problem right there no?

One night, I had BAD white smoke on initial start-up, it went away after a few minutes......... Than over the next few days/weeks I noticed coolant disapearing at an alarming rate, combined with black nastiness in the coolant....... damn double layer FWD head gasket, I chalked it up as my blown HG causing the initial white smoke on start-up, though now I'm double thinking that conclusion.

 

Thanks man!!! The only person to go from a VQ20 to a VQ35 on the forum...

It was a long and painful road for those who followed my progress. the only thing i eh do when it finally started was cry yes.... but the first drive literally took my breath away lol

anyway back to the topic at hand, i going and check the injectors as the guy said earlier change my plugs and install the FPR(aeromotive) and put some gas in the damm car and see what happens. hopefully by sat i will complete everything, the electrician will also be returning to sort out the speedo and jus run back through everything else. the ecu not in safe mode as when i started the following day it free revved to redline. i believe all the problems now are fuel related.

One thing to note though, i didn't have to do either a AP sensor position learn or a idle volume learn and the car revved and idled within spec even though while it was down the throttle plate was moved manually which would give credibility to the notion that if u disconnect the battery u can clean the throttle body without encountering problems.

 

I still wouldn't, imho.

 

You may want to grab an extra maf (You're using which???) I had very similar problems and it was just the maf. Someone at Ocean State Performance told me it was from using oiled air filters (junk Specter ones). Luckily they do have a full SS filter that just needs to get washed with water every now and again.

Ok guys, the white smoke has stopped. Now the only problem is the "Sticking injector". I intend to check the resistance and pull the injectors and soak them in injector cleaner. Do you think this will solve my problem, if not is there any way to solve this without changing the injectors???

keep in mind it was not always like this, when i first started the car it idled very nice an smooth for a couple days and it's only when i went on my first test drive that it started. The gas tank was extremely low at the time also.

MAF is good as i was using it with the VQ20 i had before i changed engines.

 

So i pulled the injectors this weekend and guess what i see oil on # 4 and 6 spark plug. #6 was the worst.

so i pulled the valve cover after remembering what u guys said about the spark plug oil seal and oil and checked the FSM to see how to get out the seals no luck so i pulled the ole fashion way a hammer and screwdriver and ponged it out only to go to the dealership thinking i will jus replace the 3 rear seals and i cooking with gas.

low and behold they tell me i have to buy the whole rocker cover!!! i was like WTF!!! it seems that the smaller VQ's can replace jus the seal but the 35 needs a new cover with the seal attached.

and the seals don't fit from the smaller VQ's. design different.

where can i purchase it online???

 

I would PM Nealoc187, he should have some extra since he didn't use um on his swap

 

Blown HG is my thought too.

 

Well if it makes you feel any better, your blown headgasket makes me feel better because I'm not the only one............

Side note, if you can't get it from Nealoc, order one for a 6th gen.

 

Well all my gremlins have been sorted out!!! the leaking injectors have stopped, not sure if it was because i soaked the injectos tip in carbuerator fluid and then cleaned it with a toothbrush and pin and also changed all the o-rings, top and bottom. i changed the valve cover and put on a new gasket as well and started her up and well lets jus say i was mosquito free for the rest of the night.

also i hooked up the fuel pressure regulator as well it holding and maintaining 50psi although it dipped to 45 at one point in time yesterday. but today it's back at 50.

started her up and she smoked for about 5 mins, carried her for a run and wow!!! tires from a standstill, strong strong pull in all gears...

still have some minor electrical to sort out but she running finally. took me 5 mths but it works!!!

thanks to everyone who gave me advise and solutions to get this done especially as i in another country...
