Hi Folks, Welcome to another DYI. In this episode i show you how to upgrade the timing chain to a newer revision on a VW polo 1.2 tsi 2011 year model. This can be appicable to all other VAG vehicles using CBZA/B engine. Das Auto. Cheers
Your engine sounded healthy if you ask me. The "death rattle" is much more pronounced and lasts longer when the chains need to be replaced. You can also hear it when revving the engine. The slack of the oil pump was ok. All chain driven engines make some noise at startup. It's just that the oil takes a few seconds to lubricate the entire chain. But upgrading to a thicker chain is always good. Preventative maintenance. And thanks for the awesome tool ideas! Nicely done!
Thank you very much. A mechanic quoted me at 1200€ for replacing the chain but now after watching these videos, i bought a chain kit for 150€ + other needed tools + oil came to around 300€ so i easily saved about 900€ But that job was a lot more complex than on my old Mondeo where i changed the cambelt with ease as its so simple
This is actually far from complex. This is one of the simplest engines i've even seen. Probably the simplest engine to replace the timing/oil pump chain ever. Simpler even than replacing timing belt on many engines, especially Subarus.
Hey mate. Awesome video. Thanks. Few questions about the crank sprocket. 1. What are the dimensions of the pipe? 2. As I just opened my kit, I noticed that the sprocket isn’t keyed, so how did you make sure it was in time? And 3. How long of a bolt did you use for that very nice tool you constructed? Thank you kindly 🖖
HI Mate thank you. 1. sorry which pipe? 2 Yes they are not keyed thats why you need the locking tools, by installing the locking tools the engine will be at TDC 3. i used M14 bolts and nuts 10 or 12 cm if i recall
The rattle of the chain has 2 causes: 1. The chain is stretched (in the case of vw polo cbzb 1.2 tsi - over 47 cm!!!) 2. The chain performs as a stretched chain (tho is no longer than 47 cm!!!) because of the internal fail of it’s tensioner! So if you can measure the chain and it the same length in cm as a new one and also inspect it visually and see it doesn’t have any damage, than the chain can be reused and you only need to replace the TENSIONER! The causes of a failed tensioner are: 1. The lack of lubrication or proper lubrication (oil loses, bad oil, low oil pressure etc.) or 2. The internal damage of the tensioner because of the km and of the usage!
That rattling noise at the first startup after replacement, was it only one time or is it still like that when starting it up? Mine has a rattling noise when startup for about 1-2 seconds, then gone. Thinking that I might need to replace mine (again since it was replaced 3 years ago). Thanks for a great video!
Hi! Doesn't the sprocket for the timing chain on the crankshaft need to be aligned with a specific zeroing position to be positioned correctly on the crankshaft when the sprocket is installed to the crank?
@frankcumaio8328 iv tried that and every time the chain jumps..this is after changing the oil pump chain only. Now im stuck because im not sho if i should change the timing chain and tensioner as well because im aware that the tensioner only works properly with oil pressure.but the only problem the car had was the noise from oil pump chain.
Thanks for the video, i need to replace front oil seal can the crank pully be removed and reinstalled with just the holding tool? Or are the crank locking pins also required?
TDC mean Top dead center. Is the point in which the piston in the number one cylinder position of your engine is at its highest point on the compression stroke. When you place the locking tool correctly the engine will be at TDC.
@@frankcumaio8328 Top dead center. If you're not certain, just place the camshaft locking tool in place and once the bolt hole of the tool aligns with the bolt hole perfectly, it's TDC.
@@frankcumaio8328 No problem. I found another method, it includes heating up the sprocket with a heat gun (600C) -> use it on the sprocket for 30 seconds and then it slides right in. Can't put any links to the video because YT deletes the comments otherwise, but the video name is 'VW Golf 6 1.2 TSI Steuerkette wechseln' by kfz tutorial bros. Skip to 24:40 and you understand what I mean. You inspired me to do the cam holder tool, I also have some scrap metal I can cut and use :)
