HELP! Second Hand Engine Blew 4 Days after service

I assume he drained the oil when he serviced it.

Did he put any oil in it?

It's seriously a common issue, and it's not always dependant on service history, and doesn't always give a check engine light before it lets go.

I did an engine in a mk6 gti last week cost a bomb and it was only a few thousand km after the guy spent over 5k getting the dsg gearbox rebuilt.

Car was always serviced on time, no signs at all, just unlucky that everything packed it in.

Usually with the tensioners, you'll hear the chain rattling for a long time after start up. This is a sign that you're about to cop it.
A lot of owners don't even notice different/terrible sounds.

Still if it was noisy after servicing and you had a good mechanic he/she would have told you that the engine needed preventative maintenance.
If you get the engine series code like "CAVE" off the sticker in your service book or boot, you can get on eBay or gumtree or start calling euro wreckers and try find the cheapest running engine.
Probably throw a new chain and tensioner on it, unless you are selling immediately, wack it in and start over.

It sucks hard, feel sorry for you

I bought a 2010 1.2L 77 tsi Polo 5 years ago.
October last year (2016) my engine blew because I hadn't taken it for a service. Idiot mistake I know.

I went to a private mechanic, he quoted me $3500 to get a second hand engine with 92k on the clock, my original engine had 75k since factory. Already knew I was at a loss, at the time I needed my car, it's 100% my only way to work, so I said yes to replacing it.
Anyway, within the 6months of having it I made sure to keep up with the services. On Monday (8th May 17) I took it in for it's 108k service, this is the 3rd minor service I've done within the 6months of having this engine and on Friday (12th May 17) I turned the car on, let it warm up and drove my normal
20kms out of my street, it revved 3-4 trying to get out of 2nd, 4 1/2 to get out of 3rd with an extremely loud rattling sound. (Rattling I experienced more with this engine than my factory engine) I get 200m from my street, turn and the car shuts down and I'm rolling to the side of the road. Doesn't start.
Tow it to the mechanic who serviced it, who also bought this engine and asked him what happened.
Engine has blown again! He said the timing chain snapped which most likely caused damage to the valves.
With this engine I paid an extra $200 to have 90days Warranty instead of 30days.

He told me on Friday, he and the guy from the car yard he bought this engine from, had discussed this is a "common" issue but bought the engine before telling me there's a possibilty this would happen again.

On monday he ran a full computer diagnostic on my car and said it picked up no faults. He did a minor service and when they gave my car back to me the rattle sounded louder than when I had taken it in to him that morning. 45mins he took to do the minor service.

I need some advice, what can I do that will get my car back on the road without me having to replace the engine at my cost?
Is there anyone else who has dealt with a similar situation?

How many services did you miss?

A design that needs full oil pressure to force out the tensioner on start up/after an oil change sounds a bit how you going. Can you run a grade lighter on cold temp oil to counter it? They make a manual tensioner for the 1.8T 20V - if I had one of these engines and the problems with the chain tensioners were this bad I'd be looking into some kind of manual tensioner solution. Or can the oil gallery to the tensioner be modded to help?
