Driving to work today, just got onto a dual carriageway and put my foot down, next thing, there's a big bang, something flies out the back of the car, and it misfires like a pig, managed to limp to work, open the bonnet to find the spark plug cover smashed, and a spark plug missing. Tried one of the others in it, and it won't do up, so it's stripped the thread.Bugger, looks like I need a new head.:(

Mum's old Vectra did the same thing but we were able to refit the plug. I'm guessing all the extra boost must've stripped the thread.

What's the plan then? ME7 head with VVT delete?

How about getting the thread Helicoiled? They always advertise spark plug hole thread repair without removing the head.

the s40 t5 and c30 t5 are 2.5 t5 as they have the same engine the focus st has

I'm not 100% but I dont think it will fit as the engine is smaller than the 2.3/2.4 engine for a me7 head you want a early 2.3 me7 or a 2.4 me7

Also sorry to hear your troubles hope its not much of a fix to get it back on the road

It says it fit a 97 onwards so that rules out the focus engine.

First of all, sorry to hear about this.

It always seems to be the modified cars that this sort of thing happens to, I've seen it countless times on here where cars that have gone beyond their standard set-up seem to bend a rod, have engine damage or something like this.

I just hope no one pops up and tells to sell it because you're chucking good money after bad with it. Interesting how people will plough thousands in to an engine rebuild..........

Bad news but easily sorted, I'd go down the helicoil route, no way on this earth the amount of boost your running would have been the defining factor of the thread failure, it's either worked loose, has been worn to excess or is cross threaded, just a shame you hadn't noticed anything before it blew the plug out..

Definitely wasn't crossthreaded, as I always do them up by hand, and give them a nip up with a ratchet once it's hand tight, though can't rule out it working loose, it's unlikely, I've changed loads of plugs in the past, but you never know.

This is what happens when a plug makes a bid for freedom.

Perhaps you forgot to nip it then? There are a vast number of T5's that run a lot of boost around the world and stripping plug threads isn't something that's reported on high hp T5 lumps... Regardless of what happened it wouldn't have been the boost that popped the plug it would have been an issue with the tread being stripped, worn or the plug being incorrectly tightened..

Sorry to hear about your eventful journey. Depending on what you want eventually with the car - I think it would be best to put a new head on it. You could use the time to have some additional work done e.g. port/polish - 3 angle valve seats etc.

The car was done yesterday, but didn't want to post until I'd given it a proper run. It's running fine again now, the spark plug hole was enlarged, rethreaded, and an insert fitted. Had a bit of a moment after I'd put it all back together as it still had a misfire on the same cylinder (5), but I'd swapped HT leads on 4 (got taken out by the wayward plug) and 5 (thought it might have been damaged by the plug detaching itself so quickly from it) for the old ones I took off last year, turns out the old HT on 5 was dead, as when I refitted the plug lead for 5 that had been on there it ran fine. Checked the tightness of the other plugs, all took a little nip more to get them tight, apart from cylinder 1 which took 2 turns!!!!! Now, I've fitted plugs more times than I can remember, so either I wasn't paying attention when I did it (it was done at the mini fix meet her for Graham's brakes and there was plenty of banter flying around) or I need to do them up tighter on a turbo engine. Anyway now my spark plug covers smashed to bits, and in the bin, I will be keeping a close eye on them, still got to get a new spark plug to replace the one that parted company with the engine, as I nicked one off the cabbie, and it's a NGK Platinum, whereas the others are Iridium.

My initial thought when I heard the bang and the misfire, with bits flying out of the back of the car was I'd stuck a rod through the block, and I'd have to get another engine for it, then once I'd found out it was a spark plug flying out it was damn, I need a new head, it was only through a bit of head in the hands thinking, and google that led me to get an insert fitted. I've spent too much money on the car to break it, but I've found through previous bad experiences that my initial reaction is worse case scenario, but taking a bit of time to think it through brings me to an easier solution, that's a lot cheaper. :)
