Triumph Spitfire Cylinder Head Strip down and Clean!
With the head off and the cylinder bores checked it was time to turn to the cylinder head itself. When first removed it did not look a pretty sight and looked very coked up. A quick dip in my parts washer and a good going over with a stiff nylon brush and the top of the cylinder head looked as good as new.
With the valves removed I started on the coked up areas on the underside of the cylinder head. With a little careful scraping and a small brass brush in my high speed Dremil the head was starting to look good again although it did take a long time.
With all the chambers clean I then re washed the head to get rid of any carbon that may have found its way into the water and oil ways.
The next items to be cleaned are the valves themselves, as the engine does not look like it has done many miles since a rebuild I intend to reuse the valves and de coke these as well. I have already tried the valves in their guide the wrong way round and there is no side to side movement so I can only assume that when the head was rebuilt it has had the valve seats re-cut and new valves fitted.
I have cleaned the valves in the parts washer but the only way to get rid of the carbon is to put them in the chuck of either pillar drill or an electric drill in a workmate. Make sure you put some tape round the valve stem before putting it in the chuck so you don't damage it. You can then use a tile cutter to remove the carbon and then some wet and dry paper to finish off.
