Hi guys as the title says really.
I just finished doing a intake manifold gasket on my vs commodore s1 due to oil in my coolant.
Everything went smoothly and did all according to a Gregory's manual.
Tightened bolts up in the pattern to the required torque.
Filled her up with coolant and started it up. Running a bit rough and figured out it was only running on 4 after taking off injectors 1 by 1. Cylinder 2 and 6. Checked for spark and no worries, and looks to me like a lot of unburnt fuel coming from the exhaust. Even changed coil packs around and still nothing.
I've been looking at it all yesterday and still nothing. Got me stumped. Any body got a idea?

Could it have got coolant into it?
How long have you ran it for?

I tried my hardest to not, did the water pump to so took that off first which should have dropped most of it out from the top. Ran it maybe 10 mins now all up.
Forgot to mention to that it is duel fuel and runs the same in gas.

Any loud hissing sounds? You might have a vacuum leak.

Double check the bolts as well.

Not any hissing noises that I can hear, that's what I first thought and hunted around but didn't find anything.



Ill recheck all the bolts when I get a couple hours free.



With the spark plugs I took them out 1 at a time and earthed it to the body of the engine and they both had what looked to be the same spark as a cylinder that was firing.
