Yeti 1.2, delivered Dec 2013, engine CBZBE9xxxx, currently not quite 35K and having a fairly easy life nowadays. 

 

No known problems at the moment (quiet starting, at tickover and at revs.), but previous forum comments on this engine leave me unsure - old chain, updated chain, or belt? 

 

No record of work on it prior to my acquisition as a three year-old.  It's likely that one of our residents can kindly answer more quickly than I could find elsewhere, so my thanks in advance..

Typo

Chain: camshaft timing chain; timing case; D - 24.10.2011... - Yeti(YET) [EUROPA 2013 year] (7zap.com)

Thanks, Wino (...also safely jabbed!), but I'm still unclear whether that's the original, or with the updated tensioner that seems to have been introduced about then.

Well there's another diagram for cars built before that date, which probably has different versions of bits in it: camshaft timing chain; timing case; D ... - Yeti(YET) [EUROPA 2013 year] (7zap.com)

 

 

 

This is an interesting read about the cam chain on the 1.2.

My thanks for all help.  Seems I'm in the clear

Was recently  told by one garage my timing chain needed replacing because it was noisey, despite it sounding how it did when I bought that car at two years old and 20000 miles (currently 10 years old, 70000 miles). I phoned the various [2] other Skoda garages and they said the chain is a lifetime part. They stated it would only need replacing if it snaps or significant wear has been physically identified by taking an actual look (not by sound). And for the former you would have the car recovered to a Skoda garage to repair. This was confirmed by Skoda UK.

Welcome,

that is true if your Timing Chain & Tensioner is one after the Upgrade that VW / Skoda did in 2011.  18th June 2011.

Pre upgrade are covered by a TPI.

Were they checking your car via the VIN?

The aforementioned garage, who stated it needed replacing, operated purely on sound. When I spoke to the other garages and Skoda UK, who took my car details, they confirmed it didn't need replacing on my car. 

But that little gem of a detail regarding 18JUN2011 is good to know.

Chains can need replacing even after the upgrade as even 'Fitted for life' wear and can jump a tooth.

Then there is the issue with some that have issues after an oil change and the tensioner having gone slack.

 

As to noise, personally i would want to be sure a good oil filter is fitted and with a 1.2 TSI i would not use the VW / Skoda recommended VW 504 00 5w 30 FS III (Long Life Oil) 

for fixed or variable servicing but would use the VW 502 00 for Fixed Servicing, so 5w 40 FS and change the oil annually or ever 10,000 miles / 9,400 or sooner.

 

The OEM Oil Filter  & Oil Capacity changed in from *June 2012*  with 1.2 TSI's, same time as the time chains. 

So 

***3.9 litre rather than 3.6 litre as it had been.***

 

Amazing how long it took some Techs at Main Dealers to know this.  Many still do not know as they were not around on just not switched on.

Thank you. This is super helpful. And I'm definitely not refuting your statement regarding replacing lifetime parts that do wear and malfunction. 🙂

I don't know where @e-Roottoot get his  dates from, but I can assure you cars were being built in Dec 2011 with the old engine block (3.6l oil capacity) and chain. As I got in an Octavia build date early Dec. 2011

 

Other dates I have seen for engine/chain production changeover have been Nov 2011. Cars will still have been fitted with the old engine until their production stock of engines was exhausted.

 

My engine started rattling on cold starts at 2 years old. Needed the upgrade kit fitted before 4 years old.

 

If the original factory fitted spark plug leads are plain and do not have the corrugated marten protection trunking, it is the old engine.

I took the dates from those given in the links from those that got the info.

If wrong then only by months because the changes were in 2011.       I was only looking at Mk2 Fabia, not other models and their build date.

If Yeti, Octavia, Roomsters are that much different then sorry.

 

The Oil Capacity change June 2012 is for the CBZA & CBZB  86 & 105 ps

If it snapped then you would very likely need loads more replacing than just the chain.  These are interference engines the valves open lower than the piston rises. Without the chain keeping them all timed together they'd smash into each other. Could get very expensive, bent valves, damaged head, holed pistons.

Basically a new engine which would cost more than the Yeti is worth therefore effectively a write off.

Would generally agree, but a good s/h engine with a warranty would only be in the £500-£900 arena plus fitting, so really no need to write-off ... its only a collection of bits after all and a good used engine can be good value.

 

 

Edited 13 August, 20214 yr by TruckbusUK

Any links or leads to sellers of good Euro 5 or even Euro 6 1.2 TSI's in the £500 - £900 range from trusted sellers that have a warranty might well be of interest to people.

Post 2011 makes sense, or Rebuilt / Refurbished ones.

That is good value - where have you seen that price? Labour costs would be significant but overall I guess it might be worthwhile if the rest of the car was in excellent condition.

My sister was given that price a couple of months ago when she had the belt (apologies chain) on her 1.2 TSI Polo let go, lunching the engine ... that was from her trusted garage in Edinburgh ... sorry no more detail than that ... but it does show the kit is out there at that type of price ... just needs a bit of digging.

tech correction.

Just stick "CBZB engine" into the ebay search box.  Loads on there I would think.

It's actually not that hard to swap whole engines in/out of cars, certainly less work than trying to repair one that requires a big stripdown.

Plenty show on ebay.

Getting good ones is something different, but if you can and it goes in and all is well you are laughing, if it has to come out and the seller honours the guarantee and they provides another one then more labour, but it is only money.

 

Preventative Maintenance can cost less, like if the timing chain is pre upgrade then maybe seriously consider having your own engine done and not waiting until you need another engine and having to do a timing chain on it.

Defo agree with that.

Obviously. I think Truckbus and I were responding mainly to Expatman's assertion that once an engine is bust, the car is history.

Yup!
