    I think the slack in the new tensioner is because there is no oil pressure yet. I'm highlighting that I think that's why. Busy doing the exact same job now. Thanks for the useful video. Wish I had a 2nd man for torquing these bolts!

    I see replacement of sprocket bot, or not, discussed and with different opinions several forums. The original Seat repair manual for this engine does NOT mention replacing the bolts. The Haynes manual says to replace. Both manual says to replace the crank bolt for comparison (and lubricate it according to Seat manual). The cam sprocket bolts are 12.9, and according to specs I find online the tensile strength of 12.9 is minimum 1220 MPa. Some googling show me that max tensile strength of cam steel is 1200 MPa, but others states higher (and I don't know about the ones in the 1.2 engine). So there will probably be similar deformation inside the cams as the bolt threads if my interpretation is correct.
    Just doing the same job with the sprockets just now after a head overhaul (burned and pitted valves and seats), and I see the same with the tensioner that "jumps" when cam resistance gets above a certain limit (as due to no oil pressure behind the "piston"). On my first attempt of turning the engine to check everything, the exhaust cam sprocket either slid on the cam or it jumped a tooth when the tensioner jumped. So I had to loosen the bolt on that sprocket and adjust the cam to right position (it was easy to turn using the timing lock and a water pump plier). I have not replaced the chain as it says only to "inspect" on 240000km, and the engine is 60000 away from that and the car will probably end its life before... New engine turning verification looks fine even with only additional 45 degrees on the bolts (as I didn't want to torque them up to full before checking again). After several rotations (even with tensioner jumping each rotation), the timing tools gets in perfectly at TDC.
    But it worries me what actually happened when the exhaust cam slid on first check. Any suggestions? Should I remove both sprockets again, degrease contact surface (as I guess friction here is the only way of transferring the torque from the chain to the cams), and put additional pressure to the tensioner when torqueing up the bolts to its first step (50Nm)? Any thoughts or suggestions?

    The tensioner has no oil pressure behind it so yes that is normal for it to compress when you turn the engine by hand.
    Oh and those camshaft sprocket bolts have to be replaced. Shouldn't reuse them.

    Thank you for the videos and the great help with this job.
    I just did mine today, same car and engine. I followed all the steps and specs and changed both chains as well. During the assembly, all marks were ok on both camshafts and the crankshaft and TDC. After torquing everything down I turned the engine and all marks were spot on again. So I finished the assembly and when I started the engine, it started straight away and after 2 seconds the tensioner pumped oil and the rattling disappeared and the engine started to run nice and smooth. But maybe 10 seconds later all of a sudden another rattling started and this time wasn't going away. It sounded from the area of the timing chain. I stopped the engine and after a while started it again and the noise was there all the time. I tried to rev it a little bit in case it needs to pump oil better up to 2000 rpm but no difference. Weather at idle or higher revs, accelerating or decelerating the noise was always there and not changing. I then turned the engine off and left it. Tomorrow will open the camshafts covers to check the timing again.
    Also, new Castrol Edge 5W30 oil and oil filter filled up to the max mark.
    Anyone experiencing anything like this after changing the whole kit of chains?

    • @Toschomacher
      @Toschomacher 3 года назад +5

      OK guys the problem is solved now.
      After doing all the work on my own all day (took me 12 hours non-stop work on my own) I was very tired and dehidrated at the end. So I mus have forgoten to tighten the three bolts on the water pump. So when I first started the engine after 10 seconds they got realy lose and the belt was half way out of the sproket. I was lucky that no damage happened from this. In the morning when I checked everything again I first saw this belt not in place and the bolts lose. When tightening them everything was fine.
      So make sure you double and triple check everything before you start your engine :)

    • @Toschomacher
      @Toschomacher 2 года назад

      @@jedgr usually when you hear chain rattling on a cold start is an indication of a slag, which could be stretched chain, tired tentioner (if it's a spring tentioner) or both. In any case the best and safe thing to do is to inspect and best change the whole kit with new parts to make sure you won't damage the entire engine if you slip a tooth or more on the timing. Especially if you have done the max mileage for this chain. Usually if you get such a noise and symptoms means you are already way beyond the chain life.

      For anyone who might need it. Part 3 is pretty much the end anyway you just put ~1mm thick bead of RTV silicone on the timing cover and you can put a very thin layer on the engine side to ensure theres a full mating coverage. The key to ensuring a proper seal is cleaning old silicone off then degreasing all mating faces.

    Hi Sandy I’m having a nightmare with these timing mark. You said your timing marks were 180 degs out on the crank at the beginning. But they must have been right 180 deg out as after you put the new chain back on with the cam tool in place you were on the exhaust stroke.
    Can you please clarify where tdc mark should be with the cam tool in? Marks together or 180 deg out.
    Many thanks I’m having a nightmare with this.
    If I put all the tooling in (crank and cam) and install the chain every time the cam position is 180 degrees out the with the mark together (That is why I think the dots/marks must be opposite when you install the cam tool) maybe!

Pulley is free wheel so blocking it will not prevent camshaft to rotate a little bit, and the 2 small tools to maintain it will brake again I guess. Any solution ?

    Firstly why didn’t you time it up to start with when you have to correct timing kit seems a bit backwards to me. But the you rattle on about flex in the chain it’s not flex it’s because there is no oil in the timing chain tensioner which hydraulically keeps tension on the tinning chain guide. The tensioner won’t work until its got oil in it as that is how tension is held onto the timing chain guide it’s not flex it’s not oil pressure in the tensioner 😝😜🙈
