Engine failure

[lichfielddriver]

Seems the cambelt tensioner fell apart, belt shredded, engine dropped its lunch down below

 

How fragile these things are... 

 

Come back crossflow pushrod Ford Cortinas

 

 

 

 

[Ootohere]

They are not fragile but not 100% bulletproof and not engines with 1 in 5 failures as in your other thread.

Was it changed at the 5 year interval as recommended by Skoda UK?

Over 25 years ago I had exactly the same thing happen on a Vauxhall Corsa GSi 16V, so this isn't a VAG specific issue. The cambelt tensioner failed one week after a cambelt change (the main dealer replaced the belt but not the tensioner).

 

We want high compression engines for efficiency, emissions, power, etc and that means having valves that will hit the pistons if incorrectly timed - we can't have our cake and eat it.

Hi, very unfortunate, but you say 'only 3 years old' - your profile does say 2015 1.6 TDI.

Ive had several since then

[lichfielddriver]

And I am in the octavia mk3 forum.... 

 

Lol

@lichfielddriverIf asking questions on engines or parts like tensioners it helps if you say particularly what engines, big, small, TSI or TDI and age etc.

Cambelt tensioner does help a bit in knowing it is not a chain drive engine.

...to avoid confusion it's a good idea to keep your profile up-to-date 😘

Well let's look at it...

Engine block cast metal

Crank forged and machined

Camshaft solid steel

Crank shells high quality bronze/phosphorous? 

 

What operates the important valve openings on this interference engine? 

 

£5 worth of 1" wide nylon webbing as strong as my braces.. 

 

Another big earner for garages either to replace or fit new engines when they fail.. 

 

Manufacturers must award designers for the best revenue streams in parts and labour

 

DMF

DPG

VGT

EGR

Anyway,  Skoda stood the bill, it's easier to sell than with no engine

@lichfielddriver  I was only suggesting in the first post of a question it might be an idea to be specific and not assume Derren Brown is in the house. 

[lichfielddriver]

I recall possibly the 1st engines with cambelts in the UK (Ford Pinto) and the soft camshafts they had too

[lichfielddriver]

I had a cambelt fail on a 1.8 Sierra turbo diesel, £400 skim head/new valves, back on the road, the 2.5di transit could shed a belt and be running again with a set of cam followers fitted

 

we are going backwards not forwards

 

Special Award if anyone can tell me the special secret of the FWD Vauxhall Cavalier (at least the petrol models)

Some of the engines were "cam safe" and would survive a belt fail. I had several Cavaliers through the 80s and had a single failure. Only damage was the oil pump.

I seem to remember that the clutch could be changed without separating the engine and gearbox - very clever.

Thats its trick

Correct term is interference or non-interference

True, but the term "cam safe" is good for non-technical people and a marketing phrase

[lichfielddriver]

Or

 

Bang n £6000

No bang no £6000

I've still got the "clutch changing kit", ie short slide hammer with adaptor to fit shaft and a set of clips for the clutch - unused, they were bought just in case, but car, a 1991 Cav GSI 4X4 2000 16V, was just too reliable and never ended up needing a new clutch!

They copied Saab from about 15 years before

Easy clutch replacement? Access panel in inner wing so that input shafts etc can be removed easily. 

Didn't work with all though - for some reason on the very latest versions they did away with the inner wing access panel! 

 

In the past I had a Datsun 100a that had a similar clutch arrangement - replaced is less than 20 minutes even as a one off DIY.
