Over the past week or so aswell as giving freshers directions and wearing silly hoodies I've been working on the cylinder for the Mondeo. After the head was taken off I took it away to be skimmed. I did take some photos but unfortunately I can't seem to find them!
The head came back nice and shiny on one side and the guy had given it a nice wash for free which was kind of him. This is a picture of how the cylinder head looked when it came back.
In those pictures you may be able to see some dark coloured circles, these are actually the valves, the valves had to be removed for overhaul and cleaning, and also to replace the valve stem seals. Below is a picture of the new valve stem seals in place in the cylinder head.
Before going back in the engine the valves needed grinding or re-seating. The valves are supposed to make a near air-tight seal but overtime and use gaps form and the sealing ability of the valve is reduced, re-seating the valves simply improves this air-tight seal. Below you'll see the grinding stick which you may have been slightly confused why I needed to buy it.
And now me using said grinding stick...
You can see whilst the work was being done the valves, springs, collets, retainers and waste steam seals had to be kept organised.
And lastly me assembling a valve ready to go in place.
Unfortunately there's no pictures of when me and rob were having to both work on the engine (as there was no one to take the photo!!!). This happened during the final parts of re-assembly where the collets had to be inserted into place. It is much MUCH easier if one person using the valve spring compressor whilst the other nudges the collets into place. So a big thanks to rob on this one, and as I was saying at the time "he is the beef and I am the magic man!"... This is due to our ability to place the collets in correctly after only a few seconds and a few good wobbles and prods!
Hopefully there will be more photos to follow shortly, I keep forgetting to take them as I go along, often as my hands are completely black! Oh and yes this was all done in the living room!!!!
