Permatex aviation form a gasket #3 non hardening is not bothered by fuel oil or water.
If you want to make sure it is not going to leak, coat the gasket and the seat part of the threads on the bolts no more worries.
I hope that helps.
Try replacing your coils or crank angle sensor.
DTC 76 - Air/Fuel ratio variation between left and right banks
This may be a false code thrown up because of the miss. However you may also want to check that both oxygen sensors are ok and in reasonable condition.
I hope that helps.
we got 330K out of the one in my wife's VR currently my VS built box is in her VR until I can afford a rebuild for hers.
We only pulled it out as it was starting to slip and get warm.
My wife's VR made this noise for a while it turned out to be the swaybar rubber.
It had moved out of location which was making the noise on left hand turns.
once back in place we had no more problems.
Let the engine check light flash 3 times the first time as a code 12 then it may show a code.
I had the system give me the same issues twice before the first time the immobilizer in the bcm,
was throwing a code and prevented the computer from telling me that the hall effect sensor was playing up...
holden will probably still sell them but it will hurt the back pocket as you,
need to get a new key fob and have it programed to the BCM.you can do this at most locksmith's and it is a lot cheaper than holden.
If when you check the codes it comes up with a 31, this may be a BCM fault as the BCM has the anti theft
module located in it and I have had 2 fail before.
VR VS and VT ser 1 all run OBD1 with and OBD2 plug.
you will need an ALDL cable to use the pcm software. Sorry
here is a link or you could just search ALDL Cables on Ebay...
Just because they are new does not mean they can't be faulty.
when the engine is idling, try pulling the leads off one at a time (and putting them back on of course).
That should give you an idea where the noise is coming from. possibly even a dead spark plug.
I hope that helps.
