Engine not well (with video)

[CallyTeee]

Took the car a run today and noticed it a bit "chappy"

Took it around the block and on the bypass, sitting at 70-80mph steady heard a pop and bit of smoke from engine and now sounds as if it's running on 3?? Any clues to fault?

Check the HT leads have not blown / chucked a spark plug out.

 

[car.crash]

I was going to suggest a blown plug too.

 

[Gus]

crack in exhaust manifold? on the exhaust manifold behind the engine tap each of the 4 pipes with a screw driver or knuckle and see if one sounds different.

I'd bet my wages on that being a plug popped out. Whip the upper inlet off and it will become apparent which ones goosed.

 

[bloke]

yup, it's shat a plug out.

.... Your wages you say? 😂:wink: Haha.

I'll keep yous posted it was a bit wet and windy today for my liking so will take a closer look tomorrow.

 

[Mr Plums]

I would also bolt the inlet down properly.

 

[CallyTeee]

Shat a plug right enough

@NorthloopCup your money's safe :smile:

I wish i put £20 on this now LOL

As soon as i seen this i knew. Remember and use a timesert and NOT a helicoil

Has it taken the threads? As you may well be able to just wind it back in. Was it cylinder 2/3 by any chance?

Edit, no, 4.

Cylinder 1 closest to oil cap.

I did try it back on a few threads and it was starting to take to it but it blew the plug out so would that increase it happening again if just put back in as the threads will be weak?

 

[Dan@SJM]

Half the time they've just unwound.

 

[MicKPM]

Not that it really matters BUT on a Renault, Cylinder No.1 is flywheel side

 

[CallyTeee]

New HT leads and put a new plug in aswell and this is it starting




Seems fine until I let it warm up at little.. Maybe I'm just being cautious but is that not a bit " chappy " it reminds me of the old fiestas needing it's tappets done 😂

 

[MicKPM]

When was the oil last changed?
