United-Kingdom Problem with Spark Plugs...

A couple of days ago my 52 reg MCS broke down.

I was doing around 60mph and then I heard a pop and lost all power. When I pulled over, my car was 'mis-firing' and sounded like it was going to blow up!

When I looked under the bonnet, one of the HT leads was hanging out. Also the spark plug had flew out!!

After putting the spark plug back in and connecting the HT lead I managed to get my motor home. However, it still isn't right. When idle and in low revs its still 'missing' and 'mis-firing'.

Would a new set of plugs fix this problem or could there be something else wrong?

Chris

Hi Chris,

The first thing to work out is why the plug had come out, was it not tight enough or has the thread in the head failed? Next thing to try is a new set of plugs as you may has a duff plug, then try a new set of leads. On the other hand fined a garage who has a diagnostic snap-on box or a like and get them to run a test. I had a miss fire went to my local garage who ran a test, result was a failing plug lead!

Happy New Year

Graham

My new Spark Plugs arrived today and I 'attempted' to fit them.

I say attempted because the plug in the 2nd cylinder would not tighten up!!! :-(

Does this mean that the thread on the cylinder head has gone??

If so, how big of a job is it to get sorted??

One of my mates said rethreading would cost 50-100 without taking the head off, another friend said it would cost s because they would need to take the head off.

Any advice?

Chris

sounds like the thread has stripped in the head,you may be able to get a "helicoil insert" put into the head in situ and then refit a plug -if not its head off ,that being the case I would simply replace the head as helicoil inserts are never a strong as the original and can fail when changing plugs ,and there a still cheap new cylinder heads around for the time being.

Thread doctor will do it without removing the head, dont let any monkey have a go either! They may well damage the head beyond repair.

I also want to mention that thread repairs are typically stronger than the original threads. Many years ago I worked in a skating rink and we repaired skates with heli-coils all the time. Not once did the repaired ones ever strip out again.

So, get her repaired and you should be good to go.

Lee - Who is the Thread Doctor? I live in the North-east so can they travel as my car is off the road and not driveable at the moment.

I have had a helicoil fitted today and the car is running again

However, sometimes the car is still missing a little bit - when ticking over and when changing gear. Also when I took the car to around 4,000rpm it was juddering and then I got my power again.

Could this just be a case of giving it a few miles to try and sort itself out or could it be something else?

It does not do this all of the time, only when I have just started the car (hot or cold).

Hope you can help

Chris

Did you renew the HT leads?

Nope, could one of them have been damaged when my spark plug flew out?

The spark plug leads are the same as the PT cruiser!

And reading the PT forums they are good for about 30K, they have a rule, change the plugs....change the leads!!

Well my MCS has about 40k on the clock so maybe I should change them.

Should i just get original leads or shall I upgrade to something a bit better (bearing in mind I am running around 215bhp). If so, which are recommended and where to buy?

Cheers

Yes, may could even be the cause of the intial problem if they were buggered, I would have changed them anyway just to be sure it's not like they are expensive...

I have just got some uprated ones from mini!

They are blue and classed as uprated, even better still they are a BMW part so no worries.

The part number is 82 110 404 488 they are about half the price of aftermarket also!

Hope that helps
