Nice to see an update video:) no worries about the gap between videos life happens Slowly getting there 👍🏻

I'm not a mechanic but did a head gasket myself a couple of months ago. If you look at the valves from cylinder 3 and 4 you see they are not black by exhaust gasses but a bit cleaner compared to the others. Would explain the white smoke when running. I think there is your problem somewhere. Could be the gasket or a cracked head.

100% that head gasket has gone I would fill the bores with oil and turn the engine over see if the bores clean up then if not I'd be worrying about piston rings on the rusty cylinder

Well if no 3 cylinder isn't knackered, the cylinder head probably is, as even i know they are tightening and losened normally starting from the centre outward swapping from left to right etc, maybe now it resembles a banana, and did i see you separate the cam cover with a crow bar, the surface's are machined flat to keep the oil in ! But best of luck, you'll need it bud 😱🤯

Hey man currently rebuilding the exact same car! Grab yourself some Seafoam and give the cylinder a good clean and go from there!

That’s scrap I wouldn’t bother chucking any money at it tbh mate

Mate there are tiny timing marks on the cams if you didnt know

Get yourself a "dingleberry hone" and try clean up that middle cylinder with some CLEAN oil with the hone, using scotchbrite or sandpaper can create more hassles where as the dingleberry hone is used with a drill in a vertical motion, this SHOULD get most of the rust (and hopefully its not pitted too terrible).

Would be cheaper and less hassle to replace the engine,I'm surprised that it even ran in that condition

cylinder 3 looks screwed dude.....I'd suggest you source a new block......you can try and clean them up with some petrol and some super fine grit paper, but you're probably wasting your time. good luck, looking forward to seeing what you decide :)

Could it have been headlift? Or pressurised pcv system

Water is getting into your combustion chamber, that is why it’s not running right, that is why it’s rusty. It should never be rusty. Only oil should be on the cylinder walls. You can’t tell if you have a cracked liner without doing a compression test but you’ve already taken the head off. The crack is more of a tiny fracture, barley visible. I’d say you do have a cracked liner, or head gasket problem.

If it's been ran out water the head be bent 100% 👍

Hey man. What caused the mould to form? The cover?

Clean up the bores more and check for cracks on the inside as you won’t really see the crack from the top, when they go the cracks are hairline, the crack isn’t actually the problem and the engine will continue to run 100% fine most of the time. The issue is once it cracks the cylinder goes oval, if you don’t have a bore gauge to check it, easiest thing to do is use a feeler gauge in the coolant passage and make sure they’re all the same thickness

Good news about not being cracked liner but cylinder 3 deffo doesn’t look great but I’m sure u will get it sorted buddy happy new year

Goood luck and keep us updated keep this content coming :)

I have bought a non running 225 ST, I done a compression test and had none in three cylinders so I was certain it was going to be a head gasket problem. I removed the engine and box because I would normally replace the bearings, re-hone the block and replace the rings. I left the head in to get skimmed, it took 2thou to level it so now I will need to fit the extra thick head gasket. I can't wait to see and hear it running. Hope your project goes smoothly for you.

Just stumbled across your Channel look fwd to further updates nice to see another focus st channel on YT

i just buyed my 1 ever ford focus st225 05 modell. now u got me scared of the issues with the cars hehe :) enjoy the vids man. cheering for you best regards from norway :)

I've just taken a lump out and swapped it. Need to workout if cracked liners or head next. Put fast line hybrid turbo, rs injectors, Airtec plenum, full hose coolant kit and big turbo boost pipes with direnza fmic and just a dreamscience map for the time being. Ran 326 on dyno, needs mapping for turbo to push 380 :)

G'day from Australia, I have a 2010 LV XR5 (ST3 Mk 2.5) - Always enjoy any ST content and really do hope its just a head gasket failure (seems more likely than cracked liners in two neighboring cylinders however it CAN happen even to block modded engines).

My drink would be vodka to help with stress and keep anger at bay 😂

Slowly getting there mick!

Id just get another engine into it mate. I think these st engines are fairly easy too get hold of. Either way ive subbed for the journey.

Same black 2007 st-2 basicly standard apart from a mongoose cat back, keep it going you will get there!!!

Hi I have a 2010 st2 with 54000 miles also mapped to 320Bhp and I love it, keep up the good work I'm here till the end of the project 👍

check for rust where all mk1 and mk2 rust through. after that decide if it is worth it to put effort in. some body panels are nearly impossible to get, not aftermarket, not even from scrap cars

You’re back! Thought you’d given up…

I'm in a similar position to you lol. I've bought a Mk2 with a suspected water pump issue (going dreamscience this week) hopefully, that's all it is. Always loved these cars, always wanted one. Now I've got one, I don't want to let it go lol. Good luck and hopefully it's just the head gasket but make sure the heads not warped too

Here for the whole journey. Good luck from estonia :)

silver 2008 focus st mk2 90,000 cp320bhp, I love it. those marks on the pistons are for the value clearance.

Good vids mate, you persevering with the car (I would)? Excuse to get an RS lump put in.

100% a cracked liner, its got all the telltale signs of it. Either cut your losses or spend about £1000-1500 on a replacement engine and pray its not blown like this one is.

Almost 💯 your linners has cracked

Engine rebuild

The problem is young guys want these cars but cant maintain them so they get ruined

finally a guy doing the stuff i want to do...good video mate

The all important question.. how much did you pay?!

You can tell there's an issue when you first started turning it over the engine sounds like it's struggling for compression

scrap it , sell off all the parts. how much for the nstrument cluster

Cracked liner engine dead m8

Think you have a cracked liner dude

Never seen one as bad as that with that much pressure coming out the header tank I think it's more then a head gasket I dont know them newer focus as I keep to older vehicles I can repair myself I think you need to sell it on or break it for parts as engine could be nackered it was cheap as the person knew it was in that way when he sold it to you it's worth taking the head of and check it over but I would not get your hopes up on it but good luck 👍

New engine mate

Good video - I’m watching the series 🙏
