So... Cams looked fine, inlet valves were all present and accounted for, head was itching....

I timed the engine up however and the marks for cam and crank were perfect! Like a muppet I forgot about a key feature on the TFSI the camshaft adjuster and fuel pump cam on the NS....

After being reminded of this fact and with some help from a good friend of mine I whipped the casing off to discover this....



The adjuster on the exhaust cam was shot... the chain had snapped... the guide for the chain had been smashed... and pretty much every tooth on the exhaust cam adjuster had been sheared off... Champion.

With what spares I had with the head came a complete camshaft adjuster, with chain and guides... So we removed the old kit and using a locking tool for the cams, we timed the exhaust and inlet cams and locked them together... New chain and adjuster were refitted and the rest of the ancillaries were refitted. Last thing to do was give the lump a rotate and check for contact/compression... zero contact/plenty compression... Happy days!

Battery on... Flick of the key... Broom broom

Not all smiles though, the engine sounded pretty rough, with a blinder of a misfire  There was a serious case of top end rattle so I quickly switched the car off and got the sump off. Unfortunately I don't have any pictures. Which is a shame, as the sump was completely saturated with sludge, even after draining, and worst of all, the oil pickup looked like it had been painted with black wallpaper paste, to the point I could not even blow through it! This has been cleaned, along with the sump, within an inch of their lives.

Oil pickup refitted, sump sealed and refitted, a few litres of the finest longlife, key flick round 2!

Engine now sounds lovely. I think the original fault must have been an ignored oil light for a drop in oil pressure/starvation due to the blocked pickup! Something so simple eh?

I have got extremely lucky with this one, the eventual failure must have happened under very little load. So when the chain lost pressure and tension, the exhaust cam dragged up the slack, snapped the chain and sheared some teeth. Meanwhile, with the last bit of hydraulic pressure left, the inlet valves were slammed shut and survived!

This leaves me where I'm now at;
Car at least wants a flywheel so will have all at once Flywheel/clutch etc.
Disks & pads all round.
