Thanks for the video. Have the same problem on my 08 Polo 1.6 Petrol. Started out as a misfire, low compression on 3 cylinders, removed the head and found out the valves were burnt
A friend's son had a Polo with this engine & I googled searched it when his car started running badly. I found out that these engines had so many design & quality of construction faults that it would be best if he just got rid of it & a professional mechanic was of the same opinion! It's beyond corrupt that major car manufacturers like VW can get away with selling vehicles that are not fit for purpose without properly compensating owners!
I am also have the misfire on Cyl 3 and its pressure was 80psi, Here in The Netherlands all mechanic garage advised me to replace the whole engine, because it will be cheaper than rebuild it. I am thinking to do it by myself ,do think it will not be hard to do it. Thanks again for this great vedio.
Is heel makkelijk! Let wel op voor handelaren via Marktplaats, ik heb tot 4 x toe een motor mogen wisselen omdat ze gewoon niet goed waren en in elkaar geflanst waren. Worden kapot gekocht, goedkoop opgelapt, niet getest en zo doorgeschoven. Kijk in het bijzonder uit voor PST Tilburg met ‘n 89.000km oud BMD blok, dat is zo’n oplichter..
I have the same car, here at venezuela is not a common car, and dont try to even refer it has a 3 cylinders motor, this is a freak car in this place, but the thing is I am looking for some catalog parts ,this type of video are very helpfull 4 me at least.
with my vw polo, the problem of misfires apears useually in the morning, and disappears after warming up, then sometimes it comes back. i checked the ignition as wel as the injectors( as my car has bifuel it was as easy as using the switch) when this problem apears my engine is limitid to 4000 revs and 130 km/h. it has fault codes 16725 cam shaft (position, sensor, wire) ,16684 (misfire) and 16555 (lean feul mixture) i drained my fueltank once so this is explaineble? im a bit puzzled because running on lpg the valves would have even more to suffer, however the above mensioned problemes are more electric, with that a valve problem could not come and go right?
@@paulraynard2226 there is really no pattern, sometimes there is no problem for the whole day sometimes after a long drive after turning it of and starting again 1 hour later. Today i changed the camshaft position sensor, so far the problem did not least reacur
Hi mate, just wondering if you are mechanic :) I've just bought a 1.2 VW Polo 9n with this engine as my first car but after only one month it has many problems. I'm also from Liverpool, are you able to recommend a garage in Liverpool that will be familiar with this engine? Thanks
@@LetsGammel1996 Check the stupid PCV valve. Mine was fucked and was drinking oil like a motherfucker. I noticed when I was opening the oil cap at idle that there was a very strong vacuum that made the engine run like shit and when I put the cap back it almost or even stalled. The valve is on the left, on the timing cover - a black mushroom thing with a hose running to the intake manifold. Held on with 2 5mm allen bolts underneath. You can open it and it's most likely fucked. Either replace the stupid thing if you got the money or semi-delete it like I did. If you're interested to tell you how I deleted it leave a reply here. Cheers!
Excellent video. I'm currently in the same boat, the car is chugging along as if firing on 2. Spark at each plug rules out coil/plug problem. No oil/water cross contamination - might rule out head gasket leak. Have just done a compression test - Nos 1 and 3 reporting 220 psi, but No 2 only makes it to 180 psi and spark plug is wet - signalling possible valve problem. Did you find any camshaft index marks so it can be re-inserted correctly? Again, thank for posting a very visually clear demonstration.
What were the symptoms except low pressure in the affected cylinder ? A friend of mine has a fabia with this engine 1.2 l, and at idle runs unevenly, no problem if it stays reved up over 1000 rpm, and one guy that tested his engine pressure said that he loses pressure in one cylinder.
@@paulraynard2226 I'm about to attempt this job on my own car, god help me 😂 I'm actually pretty good with mechanics so it looks straight forward enough. I did think you had to skim a head though before it went back on? Cheers for replying mate its appreciated.
@@paulraynard2226 Ah I suppose so, I've heard that before somewhere. I mean the car is only worth a few hundred quid now anyway so if I can save a bit on not having it skimmed then happy days.
Great video, really helpful. How much did it cost for the all of the parts? I got misfire issues with my Polo on Cylinder 1, it can't be coils or spark-plugs as their new but cylinder compression test came back as C1 - 162PSI, C2 - 175PSI and C3 - 174PSI, so Cylinder 1 has the lowest compression but no where near as bad as yours.

Why did this happen? Stretched timing chain?
Still think its criminal that a company the size of VW can't make a reliable engine. Or, in fact, releases an engine after 1990 with 2v per cylinder.
Hey. After the rebuild did you have any problems with the engine burning oil?
Al Keatinge no mate was perfect and still is today 👍
@@paulraynard2226 cheers man was told by my local garage it might, I won't be going there so
Hello mate. Just wonder if you had to put new valve seats or just use the lapping kit to fit the new valves
with my vw polo, the problem of misfires apears useually in the morning, and disappears after warming up, then sometimes it comes back. i checked the ignition as wel as the injectors( as my car has bifuel it was as easy as using the switch) when this problem apears my engine is limitid to 4000 revs and 130 km/h.
it has fault codes 16725 cam shaft (position, sensor, wire) ,16684 (misfire) and 16555 (lean feul mixture) i drained my fueltank once so this is explaineble?
im a bit puzzled because running on lpg the valves would have even more to suffer, however the above mensioned problemes are more electric, with that a valve problem could not come and go right?
René Aangenaam ! Could come and go depending on temperatures within the head, is it ok when warm ?
@@paulraynard2226 there is really no pattern, sometimes there is no problem for the whole day sometimes after a long drive after turning it of and starting again 1 hour later. Today i changed the camshaft position sensor, so far the problem did not least reacur
Faulty information from the camshaft position sensor can lead to running on limp mode, wich will almost feel like a burned out valve
I will make an update later this week
it was a faulty camshaft position sensor

Why?

Roger Owen yes it’s the most straightforward timing job you will ever do, just need to buy a cam locking tool I got mine off amazon
the camshaft will only go back on the correct way buddy hence the lock off tools ! any probs drop me a message
Hi Paul, Did you use new bolts on the reassembly any where?
New headbolts mate

Exactly that mate

Hi mate, great little video that. Please tell me, do you skim the head aswell of does it just go straight back on? Cheers!
I never skimmed it mate no just straight back in , still all fine today

Hi, what was the cause of your lower compression? Worn rings? Thanks man
@@rturner1321 yeah from what I checked it was the gone rings as it also began burning an excessive amount of oil just before completing dying
What is the cause of such thing?

Is there anything you can do to prevent this problem
