We are one step closer to fitting the new timing chain, I've nearly messed up a few times now, but I've noticed in time. Can I still save this badly neglected engine and get this VW Polo R Line back on the road.
I've never replaced a timing chain before so this is a massive challenge, especially on a neglected 1.2 tsi engine. As I delve deeper into the engine I'm finding more problems. Can I actually pull it off and replace the timing chain or is the engine knackered.
Hopefully, I can pull it off and actually fix the engine faults, The EPC and Engine light are on, but The engine has a misfire, Is the timing chain stretched or is it knackered.

I would highly recommend this guy as his attention to detail outweighs other YouTube car repairers. And he is working in a small home garage.

Great video. A tip for pressing on the drive sprocket, heat it up in a toaster oven or something similar first. It will expand slightly and be MUCH easier to press on. You can also use a bolt in the threaded hole of the crankshaft and press on the sprocket using a nut and a washer or socket. This way you don't have to hit on the crankshaft in a longitudinal direction. Anyway, looks like the sprocket came on without a hitch!

Love a video where things don’t go according to plan. Makes the rest of us feel more human

All you needed to do to sort the chain being pulled was undo and re do the cam pulley…but other than that spot on and I’m a VW mechanic!

Congratulations M8 glad to see you are in good spirits.The salvage game will send you through a roller coaster of emotions.Sometimes it is as simple as a rounded off bolt to ruin your whole day.But when you get past the barriers and make it to the finish there is no better feeling to know you did that.In the words of Dee from salvage nation KEEP IT MOVING!!!!

I have to do this on my Touran, 1,2 tsi 105ch. Very insightful video, and very much appreciated!!

Loving your videos mate. I'm not a professional mechanic, but I spent 50 years as an aircraft maintenance engineer & have rebuilt/restored many cars & motorbikes in that time. I have just done this job on a mates vw caddy & it was really simple. I think where you went wrong re the timing, was tightening the cam sprocket bolt before you fitted the tensioner. Anyhow, all you had to do was slacken the cam sprocket bolt, rotate the crank web to the stop & retighten the cam sprocket bolt. Anyway, no matter & you got there in the end. Keep up the good work for us all to enjoy.👍

What a great channel….you really go into detail on how to fix a problem…. Other channels need to take note because this is what we want to see…not tell us what you’ve done after it’s done with no video to show it!!! Great content I hope people see your channel for how great it is….brilliant…”❤

Great job , pay attention to the tiny differences will help and usually I soak the chain in oil before installing

@ashleygriffiths441 2 years ago

Great video mate, your plodding along with the job nicely.

Plus it's always best to double and triple check your timing, it's something that I always do myself.

Looking forward to seeing the next installation video. 👍

The coloured links align to the marking on the cam sprocket and there should be one for the crank sprocket, they are there to show you that you have the correct teeth on the none tensioned side of the chain, I would think when releasing the tensioner you should have the cam sprocket loose so it can turn, turn the crankshaft to make sure it is pressed against the locking pin and then release the tensioner. As the cam sprocket can turn all the slack from the none tensioned side will transfer to the tensioner side at this point you can turn the crank to make sure it's still against the pin and tighten the cam sprocket. Pull the pins do the 2 turns on the crank but stop just before TDC or only turn it 1 and 3/4 turns, insert the crank pin and continue turning until you feel it lock refit cam locking tool if it fits great if not release the cam sprocket and turn the camshaft until it fits retighten and redo the 2 turns. normally you'd have the rocker cover off and would be able to turn the camshaft with a spanner :)
