hi guys i got a vr v6 and when i start the car it cranks over abit and blows smoke when it starts what i was wondering is on the fuel line where it sits up behind the drivers side rocker cover theres a little metal thing that sits in the fuel hose like a very small fuel filter just wondering what this thing is a regulator or ? and could this have anything 2 do with my hard to start smokey vr i got a pic here of it but i dont no how to add it to this message lol cheers anyway muzza
the thing on the end of the fuel rail is the regulator. there should be a fuel line coming of the end and a vacuum line from the side to the intake manifold. the only way to check the regulator is with a fuel pressure gauge. tell us the readings with the engine running at idle and the engine off also
Highly likely ur fuel regulator. I had the same issue with my replacement engine. I have to crank it and accelate to get it to start and a big bloom of white smoke would come out the back. Changed the regulator and starts first time all the time now.
