Do the rings spin freely by hand? If no they could have been squashed when the valve/piston contact occured.

Yes they all spin easily by hand.

Any damage to the ring lands (the gaps and part of the piston around the rings)

Not that i can see but going to clean them up tomorrow.

Now is the time to fit new rings and hone the cylinders.Especially if had high oil consumption.

Regardind the honeing is there a resonably priced tool i can buy to diy this?

This has the highest reviews of what amazon has to offer

I managed to do this same thing with mine - after swapping my intercooler I managed to nick the edge of my drive belt on the AC union and the belt thread unravelled itself and posted itself into the timing belt.

Despite the financial impact, it was possibly the best thing I have done to my Mk5 - head rebuild & injector clean seemed to restore power. new valve guides & stem seal + DIY Turbo rebuild also helped - now my engine barely uses oil.
As its off, get a vacuum pump rebuild kit from ebay.

If I had to do this again, the only thing I would change is to remove the misery with both timing belt and chain - I managed to get both a tooth out in opposite directions - correctly installed, my BWA belt seems to always be 2/3 of a tooth out comparing cam & crank timing marks.


Thanks for the encouragement.

Regarding the valve guides these are easy to remove/replace.

I've never used that type myself, the garage ones I've used are the 3 x stone type. Can get them for under £20 off eBay I've seen.

Both types will do the job.

To do the honing do i need to take the crankshaft out? There are also the oil feed at the bottom of the cylinders

Just got to be careful at the bottom of the stroke not to hit the crank and oil squirters. The squirters can be removed , see Ollievrs thread about his oil pump woes.

I just sent my head to an engine shop for rebuild - £225 for full rebuild, including new guides.

One other tip - when reinstalling the Turbo - bolt on all the pipework that connects to the core before you mount the turbo - it will save a lot of swearing

Where is the best place to get the bolts? Are vag bolts on eBay well priced?

For faster delivery and original quality I'd go straight to your local dealership's parts department, usually there similarly priced to eBay but you're guaranteed quality. In Ireland parts collection usually takes 2 working days (parts are shipped from the UK), so I'd expect it's next day or same day collection in the UK.

You can also go to Skoda dealerships, they sometimes sell the parts cheaper (or so I hear).

Best to call the parts departments of each just to get quote for prices, double check with them that they are quoting with VAT included, ask for estimated collection time, and then compare with eBay.

As always thanks for all your help guys.

While I wait for parts to arrive I've been trying to clean up the mating surfaces.

I've seen some videos where people use 3m disks on the block. Any tips would be appreciated?

I'd avoid at all costs anything like abrasives that will throw gritty stuff everywhere, you'll never be able to get it clean down all the passages. Use a plastic or metal scraper.

Look at 0000 grade wire wool or 3M non woven pads The white ones are the finest  I think :thinking:

I've ordered a carbide scraper. I think I have some fine wire wool. Will give it a go.
