TDI Posted August 1, 2007 Author Share Posted August 1, 2007 We use a special dummy cylinder head when boring/honing the block to pull everything into line prior to the machining process. This is the block assembly fitted with crankshaft, pistons and rods, and showing the Cosworth head studs Quote Link to comment Share on other sites More sharing options...

TDI Posted August 1, 2007 Author Share Posted August 1, 2007 The pistons crowns showed a remarkable amount of carbon deposits for such a low mileage engine Any particular reason for this? Running on 95 RON or something, just poor quality fuel etc? Hi Jacko, we found out that the cylinder bores were slightly oval which causes an inconsistant piston ring seal Quote Link to comment Share on other sites More sharing options...

TDI Posted August 2, 2007 Author Share Posted August 2, 2007 We like to add little "finishing touches" like this special treatment to some of the metal components. The cost is disproprtional to the value - it only costs a few Pounds to do but it looks a "million dollars" so is well worth the effort Quote Link to comment Share on other sites More sharing options...

Cheers, Rob. Hi Rob, the carbon build up is the result of oil consumption, and can ultimately lead to an increase in compression ratio and "hot spots" in the combustion chambers - which can cause detonation.
