Misfire and Limp Mode Diagnosis - Vauxhall Omega

Having had the Vauxhall Omega for only a couple of months, she's already let me down. In this video I try to find out what the problem is.

Trying to fix it but making it worse, is certainly relateable, and it's often big problems caused by small fixes. Like, oh no a frayed wire, I will just fix that. Then the other wire had the same issue (but unseen) now there is a small fire and a sensor shorted out so the car won't start.

Cam cover gasket leaking oil into spark plug wells causing misfire... where have I seen this before... ah yes my SW20!

[@pahooper99]

Yay your back. Normality has returned to life. All is good 👍

[@davespoon5082]

Whoohoo. Nice surprise, my favorite KZbin show.

[@blusun2]

💯

[@pahooper99]

Totally agree with you there. Mine too. 🎉

[@EnginesandUnfinishedBusiness]

Thanks, we really appreciate it 😄

[@oscarwithers4599]

Awesome stuff mate! Looking forward to the next video :)

[@FixingWithFriends]

I thought you were just getting it as a sleeper build. But... I can't say I am surprised it had some issues. I am glad it was not like... a timing chain skipping and destroying the engine. It has a nice pair of intakes though.

[@EnginesandUnfinishedBusiness]

Yeah, I expected issues, but I was also expecting to be using it a lot more than I've been able to so far 😅 annoyingly it is due a timing belt, although I think it's a non-interference engine at least (although I should probably double check that)

[@Oblithian]

OH NO! Don't tell me that, now I feel like I jinxed it! Hopefully it is non-interference. Anything with a belt should be (IMO), a friend's Aveo destroyed itself one day because the belt snapped at 90,000km.

[@BennyHarry]

Great to have another video from you!

[@PowerBeeKill]

You might struggle to get them new rocker covers. I’ve manage to pick up from eBay 2.5 v6 vectra aluminium covers 👌🏻 hopefully you’ll be lucky to ! And can’t wait for part 2 ! I need to see where is valve brother !

[@EnginesandUnfinishedBusiness]

Thanks, part 2 is up now. Luckily I didn’t need new covers, just the gaskets, although good ones of those weren’t easy to find for a good price 😖

[@alanryderb]

Vera, that was what my Zafira was called. It was wicked Vera at first because of the WKD reg. Nearly bought an Omega many moons ago but got a cheap Vectra instead. still like them though

[@EnginesandUnfinishedBusiness]

If you want an omega I’ve decided to sell mine 😂

[@Mong00se]

thx man, i had the same issue with my 2.6 v6 a week ago. my mechanic changed the left side of the coils, and after this video i try to change the other side myself 😁

[@seancostello387]

What is all that schmoo on the inside of the intake plenum? I've never looked inside my intake runners but I hope they don't look like that.

[@EnginesandUnfinishedBusiness]

Mostly oil from the crankcase breather. It’s pretty normal for older cars that don’t use a catch can as the crank case is vented back into the intake, and that will always bring a small amount of oil with it, which builds up over time

[@GodOfBiscuits66]

Man, whoever owned that bodged it together. I hope this is the biggest problem you have with it.

[@EnginesandUnfinishedBusiness]

Indeed, and I’ve already found more bodges

[@t.fk2052]

Did the car make no attempt to start at all after it stalled

[@Elkadetodd]

It's a Chevy. Cylinder 1 is on the port side (passenger for you), unless that specific motor is a special case.

[@EnginesandUnfinishedBusiness]

This is must be a special case, as according to the labels cast in to the engine cylinder one 1 is on starboard side (my driver's side). Might be a British thing, as according to wikipedia all the Omega/Catera V6 engines were made in England

[@frisco557]

4:00 You could have used the impact driver in the blue case to loosen that phillips screw. Its what they're designed for. you just set the driver to loosen, set it into the phillips screw, and hit the end with a hammer.

[@EnginesandUnfinishedBusiness]

That would have been the next plan. As the screw was already a bit stripped I wanted to try the more gentle approach first - it was only a little 1/4" ratchet, so I wasn't putting much torque into the bolt

EAUB: "See you in a few seconds or in the next video........." Me: "How many seconds should I wait until I must accept the reality?"

[@EnginesandUnfinishedBusiness]

About 3,456,000 seconds
