It's rebuilt, and it runs, which is a bonus I hope I never have to do that again.

New inlet valves fitted (left), all valves lapped in. Valve stem seals also all replaced. Found two cracks on the exhaust manifold. I welded these but I'm not posting a photo as it's not pretty but it's solid. 😬 It's a pity the Cat is built in to the manifold otherwise I'd have replaced it.

Hi all, I'm rebuilding my engine but need to double check the torque figures for the head, rocker cover and timing chain cover. I've found some info online but need to double check it's correct. The engine is 1.2 16v 3 cyl' CGPA 2014 Fabia Mk2. I have torque figures of 30Nm first pass, then 1/4 turn 2nd, and 1/4 turn final pass for the cylinder head. For the rocker cover, 10Nm plus 1/4 turn. Cam shaft gears, 50Nm plus 1/4 turn. Nothing found for the timing chain cover. If anyone has a list of these to check my figures it'd be appreciated. Cheers P.S I'll be updating my other post as it's rebuilt.

😪 Spares arrived on Monday but I won't be able to start any work for a few weeks. Valve guides are good. Valve seats (all 12) are in very good condition for 65k miles.

Cheers I'll check them out once I've got the valves out and see how much damage there is. I have and Audi S4 (3.0 V6 supercharged) which I carbon cleaned the intakes (walnut blasted) early this year and I thought that was advanced. This little 3 cylinder is definitely testing me.

Not yet but they're in my amazon basket. Something else I've never done so will get that tool also. And watch some Youtube videos 😬

Thanks Wino, I'll do that when my removal tool arrives. My last post was for sepulchrave, I still can't edit posts to quote 🤔

I don't know any places around me that offer that service. Garages in and around Aberdeen are extortionate price wise at the best of times, they mostly just want quick jobs. I'd probably have to travel to find someone offering a rebuild service. Now I have it apart it's not too daunting (putting it back together and getting it running may be another story 😬).

My photos didn't upload on the last post and I can't edit. Here they are:

Just an update on my predicament which might help others in future. My local garage couldn't take my car in as it would take them too long and they have a backlog, I don't know any other garages around that I'd trust so I had no option but to strip the engine myself. Unfortunately all the intake valves are bent and sitting in the same plane as the piston top. This is my first time doing an advanced job like this so I have more questions to get this thing back on the road. - Do I have to lap the new valves? - What should I replace other than the valves? Stem seals? I can't see much else on this diagram (4cylinder, I can't find the 3 cyl version) which would need replacing. I'm awaiting delivery of a spring compressor tool to remove the valves. - What jobs should I do while I have this thing apart? List of parts so far: 6 intake valves and seals. Timing chain kit. Head gasket RTV silicon for the timing and rocker covers. Spark plugs (they're due). Oil change Coolant. Cheers

A view of inside the cylinders: The flakes are small, must be the coating on the valves. I managed to pick up a few with a magnet. The second photos looks like impact damage? I'm awaiting a quote from my local garage. Thanks for your help Wino. Much appreciated. Not knowing what's faulty is sometimes worse than finding the fault.

It's not looking good. I've just inspected the cylinders (with a cheap USB inspection camera) and I can see debris. The timing is also off with cylinder 1 at TDC. Pictures say it all. I'll add more later from my laptop of the cylinder.

Thanks Wino, that makes sense. I'll have a go tomorrow although I don't think I have a 12 point socket, luckily I have another car. Is cylinder 1 closest to the timing chain?

I just watched this video (same chap): Timing chain replacement so a bit too much work for me, it would take me weeks. I pulled the end covers and took these photos. They look aligned. What are the chances both jumped the same number of teeth? I also put both images in to GIMP and aligned them and I can't see any difference in angle. If it's not a jumped timing chain what else would stop the car starting after a few stalls? I don't think the camshaft sensor failing would stop the engine starting ( I may be wrong).

I just found this video so I'm off out to check: CGPA timing check If mine is off what would be the process of resetting it? I'm pretty competent when it comes to mechanical work but I've never worked on timing systems.
