Industrial engineering and oilfield services stocks kept the London market in positive territory on Tuesday as fears of Greece defaulting on its debt appeared to be receding.At 1545 BST, the blue chip FTSE 100 was trading up 0.34% or 23.22 points at 6,848.890 as the headline Markit/HSBC Chinese manufacturing sector purchasing managers' (PMI) index rose to a reading of 49.6 from 49.2 in the prior month and the US economy showed renewed signs of growth.Engineering stocks were natural gainers as oilfield services company Petrofac (up 6.38%) said it had mostly performed in line with expectations in the first half, though development of a flagship project in the Shetland Islands will incur further costs.
