O/T Vectra engine prob
Hi all
Started my tin top tonight, idled fine, pulled off fine then about 100 yards down road engine started chugging and wouldn't rev, drove a bit
further thinking it might be damp plugs or leads, no differance.
Stopped car and lifted bonnet, smoke coming from inlet side of engine, idle really ruff and wont rev properly, Any ideas?
I'm thinking head gasket

When you say "smoke from inlet side" what do you mean?
Like blue oily type smoke from the block on the inlet side or steam from the block on that side or coming out the inlet tract?
Might help pin it down a bit - Iwouldnt suspect head gasket yet - ive had em go about 3 times and they've all driven fine for ages until they
ran out of water!

Hi Geoff
Smoke looked white by torch light, could't really see where it was coming from with all the inlet hoses and stuff
I'm hoping i can sneak off home early tomorrow to have a look in daylight

Lots of smoke or could that just have been condensation evaporating away? Any oil in the coolant expansion tank, or mayonnaise in the oil filler
neck? Time for a compression test I think. Good luck dude!

smoke may be a red herring... have had many problems with sticking/faulty egr valves on ecowreck engines, this would also cause a lack of power and
make it run quite lumpy under load.. its worth investigating

Some Vectra engines suffer with water pump and timing belt tensioner problems . Check valve timing before attempting to start engine.

Hi again
Had a look at car, only running on cyl 1 & 4, plugs 2 & 3 were black and wet Plugs 1 & 4 black and dry, Going to try new plus tomorrow
Anyone no how the coil pack works? just wondering if it fires in pairs like ford do?
Also may have found a reason for the smoke, found a big split in the inlet hose right next to where the rocker breather joins it

Oh good not the HG then. Vaux distributorless system is almost certainly wasted spark so fires in pairs as you suspect. Sounds like half of
it's fried so get hold of a replacement coil pack and replace that split hose.

Glad to hear it's not timing belt problem
