Hello all, i know its annoying question. Looking for advice or if someone local who could investigate for me..

Long story short..

Bought 2008 mk2 st.

Engine freshly forged, has westwood liners.
Previous owner cracked liner, so he gone to Brighton to devil development company, where they supplied block with uprated liners and fully forged. Can confirm that work was done 100%, as rang them and asked if this car been to them and what was done to it.

So it started misfiring randomly on cold and hot on idle only, loosing coolant, not to much.
Then noticed it started loosing more coolant and pressurising expansion tank. Other day back from work and noticed white steam coming from exhaust.. That got me really worried, obd showed misfire in cyl 3.
Took spark plug out, it was soaked in coolant...

So im confused here..
He's gone for westwood lines so it wont crack ever again, but whats going on then? Head gasket? Its rarely blowing head gasket.

Any input appreciated!

I'd get all cylinders compression tested and if possible a borescope inspection of each cylinder then go from there. Either way the head is coming off if you want it repaired.
Thanks for input. I know either way head has to come off. Anyone here located in Buck's, Bed's l, Oxfordshire?

If Devil Developments did the work they are the first people I would be going back to in order to give them a shot at fixing it. Not sure what warranty they offer but even if not it would be the best bet. Otherwise if AN Other garage take the head off, do anything to the engine, & find an issue then DD have no responsibility or reason to cover anything to fix it.
Hence my first call would be to DD.

Have a chat with DD. Do remember that any warranty is likely to only be valid for the owner who paid for the work. You never know though, DD may be willing to warranty it for you, given that they type of work it has had done is rare and distinctive.

Good luck.

I wouldn't rule out head gasket, given the other work that has been done.

I would be extremely surprised if it was a liner problem, it's supposed to be 3 x stronger than standard and for builds up to and over 700 bhp.
Headgasket is most likely.

Have you actually spoken with devil, they may give you a few ideas to check first.

Sorry to hear about the warranty, but this is exactly why the only person who works on my car is me!

If it is the headgasket or liners (I would say based on the amount of coolant you've described it's definitely the headgasket or the head itself has failed) then a job done properly with proper parts 'should' last a lot longer than one year. In my opinion handing over thousands of pounds to a specialist is a lottery. I'm not having a go at Devil Developments in particular and they do have a generally excellent reputation but even if they take a lot of photos of the work it doesn't necessarily mean that the mechanic torqued each and every one of the headbolts through each stage correctly etc. The only way you know that for sure is if you do it yourself.

Thank you, very good reply! I'm diy guy, but basic stuff, never attempted to take head of etc. Will update when boroscope will be delivered, hoping something will be visible.. if not, will go to the garage for head removal and inspection.
But still what worries me al lot is, its not leaking to cylinder 3 all the time, only when engine is up to temperature, as expansion tank pressurises. Thought if gasket were gone it would leak all the time regardless of temperature or pressure in the expansion tank. (might be wrong here). Can someone shed some light here please?

Also if anyone running with Athena head gasket? looks stronger than ford one..

If it is the headgasket, then dependent on the location and nature of the break it could leak more when hot. Both the head and engine block are aluminium so there won't be a significant difference in the thermal expansion rates as the engine gets to temperature.

It could be a fracture in the cylinder head itself but based on your description of the soaking wet spark plug I think that would be unlikely. A garage should be able to make a fairly quick diagnosis.

One more thing - it doesn't really matter much now but do you think the previous owner sold it on knowing the fault was there or was this something that happened after you purchased it?

I think head gasket.

That warranty isn't worth the used toilet paper it is written on.
Absolutely agree.

Absolutely agree.
No, previous owner is absolute brilliant guy, helps me in every way. Only thing he moved to Italy, other wise he would be happy to take head off himself. But still he is on the chat with me whenever i need something. Provided all lost invoices etc.
When told him what happened he asked not to scrap it if i was going that way, he wanted to send his friend to buy it off me. As there is some sentimental value to him (bought it and worked on it with his grandpa who passed away). And i saw his face when bought it, i had same face when sold my other car that i was attached a lot.
When picked up this car, haven't had any problems whatsoever, as i always check my cars before/after longer trips checking coolant/oil levels daily. All levels were spot on until last week when started noticing coolant disappearing somewhere.
So don't think he knew anything, or sold me with issues already.

I would agree with the guys and imagine its the head gasket. I had similar setup to yours, forged internals and linered block, running around 370 bhp and my head gasket went 2000 miles/ 6 months later. No reason i can think of other than the head gasket might have had an issue when installed or head itself and went one day when i was pushing it hard maybe? The car had no symptoms apart from an initial misfire and bit of coolant loss. I'm pretty meticulous with the up keep of my cars and had only replaced the header tank with a new one a couple of months earlier, due to it getting mucky from the split liner and a couple of days after the misfire,i checked the cars coolant level again and noticed the header tank had now been contaminated and instead of a nice red/pinky colour it was now murky and emulsified. I did the hydrocarbon test just to prove the obvious but after it failed the pressure test, had the head off and skimmed. Can only assume it was faulty parts or workmanship, as the car had never lost coolant or over heated.:unsure:
