Water and spark plugs :s

DJBadBoi

I've recently got a misfire on my coupe. Thought I would change plugs just invade it was that but when I removed coil pack I found antifreeze in no4 spark plug hole.

I've been looking everywhere to see where it's coming from but nothing.

I dried all water up and thought I would drive round block and when I got back it was full again.

If anyone could help would be so much appreciated as I don't really want to drive car till I find out what's causing problem.

Cheers Danny

Bad News 🙁 looks as though the plug has been over tightened at some stage, this in turn causes damage to the cylinder head. No fix possible, new head may be required or try K Seal as a cheap alternative. Lots of threads on here about this problem

The plugs haven't been overtightened as I'm the only person that's changed them and Only started about a week ago

sounds as if head is cracked m8

ask yourself where else could the coolant come from ?

As above. Did you use a torque wrench? Usually the thread cracks whilst being removed.

DJBadBoi

Checked at work today it's it is cracked at bottom of spark plug hole 🙁 so basically I need to get it changed??

JohnnyN

New head then.

DJBadBoi

good job ive got a spare 😛 but that cuts my bank holiday weekend out fixing car.

Is there anything else to check before I assume that my cylinder head is cracked? Had a flat spot about 3000 revs so went to check the spark plugs and found pot 3 full of coolant and a little in 4 too.
Only picked the car up a week ago so won't be impressed with a cracked head. :-)
