Engine problems
@PipH unfortunately they'd already broken the engine before I came across that one as well! 😞 scoured all over the internet and noone in the UK has got a CUTA engine! @TerFar That was my next step until I had a look at the service manual... to get the head off you have to pretty much remove the engine anyway and then have the faff of tearing it down and trying to find the fault to repair it, and as I'm doing all of this on my driveway in a cold and wet England I really don't fancy that right now! I've ended up getting an engine shipped in from the Netherlands! Should be delivered to me this week... annoyingly I'm also in the process of moving house at the moment so not what I needed! I'll work my way through it gradually and once I've got the car running again I'll strip down the old engine when it gets warmer again and find what the problem was and see if there what can be salvaged and sold on to hopefully help someone else who ends up in a similar situation!

Engine problems
Hi both, thanks for your responses, for some reason I didn't get any notifications of responses so didn't realise there had been any. I've done the compression test, cylinders 1 and 3 showed 20-25 bar (mostly at the 25 bar end, there was just 1 test that showed 20 but I think that was the gauge that caused that as the video I took of the gauge showed the needle rise then suddenly drop and come back up again on the last turn over) and cylinder 2 only returned 1.5-2 bar. I removed all 3 injectors, from cylinders 1 and 3 I had to use the puller to get them out, cylinder 2 however I took out first and was able to just pull it out by hand with pretty little effort and the copper washer came off in my hand once I had it out. I tried moving the injectors around to see if the problem followed (to see if it had anything to do with the loose injector and washer) but it yielded the same result. While doing this I also did the oil cap test (to see if it gets blown off the filler hole by crank pressure) and while testing cylinder 2 with original injector and injectors from other cylinders it still blew the cap off, but testing other cylinders with injector 2 didn't blow the cap off. I've also had my endoscope down inside the injector bore hole to examine the piston. Cylinders 1 and 3 you could clearly see the injection pattern as darkened patches on the piston crown, cylinder 2 was very wet where you could see it had been injecting but not igniting. I couldn't see any noticeable holes in the piston but it was tough to see for definite, and unfortunately couldn't angle the endoscope to see the cylinder walls. I also got the endoscope down the air intake and the inlet valves do have a lot of build up on but all 3 cylinders were similar in that regard, I wouldn't say cylinder 2 looked any worse. I haven't been able to get to the exhaust valves as my god getting the exhaust manifold on and off is not an easy task! I've had the rocker cover off and all valves are opening and closing as expected, none appear to be getting stuck open/closed. I tried to do a clearance test but I could only do it on a cold engine so don't believe the results were accurate. Cylinder 1 had 0.25mm clearance on the intake valves, cylinder 2 had 0.23mm, and cylinder 3 you couldn't push down on the hydraulic compensators at all so the clearance was 0... so this just made it all the more confusing! At the moment I'm at the point of thinking it is going to be easier to get my hands on a second hand engine and just swap it out as to remove the cylinder head to check the valves you have to get the engine out anyway! Unfortunately I've got the CUTA engine which seems to be like gold dust and I can't find a replacement in the UK! I've found one shop on ebay that has broken a car that had one in but it appears they've already dismantled the engine 😢 I've managed to find a couple of CUSA/CUSB engines... does anyone know what the differences are between the CUS and CUT engines? Are the blocks and internals the same but with different turbos/coolers/injectors etc.? Would I be able to use the external parts from my CUTA engine on a CUSA/CUSB engine block to basically rebuild it as a CUTA or is it sadly not that simple? Thanks again!

Engine problems
Hi all, New to the forum and wondering if anyone has any experience that might be able to help. I've got a 65 plate fabia 1.4 tdi (CUTA) with 126k miles on the clock and it isn't happy. A couple of weeks ago when I was driving home from work I lost all power and the engine was running poorly. Managed to nurse it home, check with VCDS and it pointed towards a turbo fault. Took apart the air intake and there was oil basically everywhere! Poured a lot out of the charge air cooler and pipework, MAF sensor caked in oil, EGR pipes dripping. So I purchased a second hand replacement from a breakers, spent 3 days draining the engine, disconnecting pipes and wires, dropping the subframe and engine, getting off the DPF & SCR, removing the old turbo and installing the new one and putting it all back together again. To my dismay, it is still not happy. The engine will start and turn over but running rough and seem to have excessive crankcase pressure. When I removed the oil filler cap it was almost blown out of my hand. As the engine got warmer it got a little less rough but still not right... even for a 3 cylinder it's bad and engine rocking about. I've attached the log files. Note that the first one has a huge number of fault codes as I had to connect the battery back up while everything was dropped and disconnected so it flagged faults for all the missing sensors etc. I cleared these faults and ran it, initially it then flagged up turbo actuator stuck and implausible signal for cylinder pressure sensor; stupidly I didn't save a copy of the log file at this point. Cleared the faults and ran again, this time the stuck actuator fault went but was replaced with implausible signal as well, as is shown on the second log. The cylinder pressure sensor is showing 12.7 bar, and I believe on idle should be 20-30 bar. I haven't done a pressure test yet as I don't have a tester so am now looking at purchasing one. Does anyone have any experience with similar? Have I been sold a dodgy turbo? Could the turbo actuator be faulty? Could it be the vacuum pump? Have I got a pressure leak either via valves/piston rings? Any suggestions would be massively helpful! Obviously pressure testing needs to be the next step (though slightly concerned that the more I run it then the more chance there is that further damage might occur). TIA.
