right, situation is that the original head ( 2000 2.0 16v ) was sent for skimming and checking after head gasket failed for the 3rd time, got a call saying it was cracked through the inlet manifold side so managed to ebay, a 1999 vectra head( part nos match but no 2.0 2.2 cast on side) with 65k on clock. head arrived and was bolted on new gasket and bolts. moment of truth arrived and fired it up...somewhere between a rattle and a thwack noise appeared, ran on fast idle to see if it just needed a nice long oil pressure build up.. but no. pissed off shut bonnet went inside and contemplated ringing scrap man to collect ( which is were i stupidly sent the complete old head)
nothing better to do today so gave it a last go. took out camshafts and low and behold 2 of the exhaust lifters were sat lower than the rest, as in the others bounced back when pressed but these were stuck down, put the in a bowl of oil and pumped the piston inside but they just didnt pressure up just slid in and out very easy not like the others that kept there pressure. am thinking that i have the problem just wanted to see if anyone can give a second opinion before i go pissing anymore pennies up the wall ( cos it needs a windscreen as well and then moting as its been sorn for last 18 months) any help/ advice would be grately received. cheers chris.
