The Nanstone - 2.0 16v CR - GTB2056VLK build

[Ruan]

So as some may now know, I've got myself a cylinder head for the new engine project which will start being put together soon enough.

The head will require a bit of work to get it back to the correct state sadly, but I've had all the valves out, cleaned those up with a wire wheel in a die grinder and cleaned out the inlet ports - absolute nightmare to get all the EGR crud out, the worst of it is now out, but the entire head could do with a dip in something to get the last of the cruddyness out the casting, it's clean enough, but not where I'd ilke it to be.

I'm waiting on a few parts that need installing, but undecided whether I fit them before or after skimming and cleaning the head...

Anyway, we all like pictures - the 16v heads seem to have issues with their cam bearings, but thankfully as you'll see, the cam bearings are in near perfect condition. It'll take a bit of work I think to make sure the injector bores are nice and clean, just very difficult to get anything down them! Same goes for the inlet ports, lots of odd shapes and castings to generate swirl, but that's life.

There's pictures at various points throughout the process of my initial cleaning and disassmebly:



Can see the EGR shite here on the swirl flaps (they're being removed as always):










Some of the unfortunate damage that happened during disassembly before me picking it up, easy enough to sort, will just require a quick tickle back and maybe a skim of monkey metal and then make sure it's flat all round, I'll get on it with the DTI as it's just sealant used, rather than any gasket










Anyone who has worked on a 16v head will know that they're actually a nightmare to get the valve spring compressor in, due to the inlet ports running down the centre of the cylinder head, so space is very tight, so there were some modifications to the valve spring compressor to get it to fit in correctly, I didn't just chop the end off and weld some bar on, ended up doing it properly and making it unboltable even - it can be returned to stock at any time, get me! Don't get me wrong, I was very tempted to just chop the end off though!




Tickled the backs of the valves with a die grinder with a reasonably light wire wheel, just to get the carbon off.


Back together again and at least clean enough to hump round without fear of shit getting everywhere!




Pretty boring, but it's shitty work that had to be done. My new years resolution is to document better what I do - so here goes, hah!
