Poor acceleration after head gasket change

waz · Apr 28, 2013

Just replaced my head gasket, starts fine but lumpy acceleration and a bit smokey(blue). Could this be air in fuel? have slackened off fuel return pipe and pumped lever, + bleed screw on filter head. Any ideas much appreciated.

if you need to bleed pump do it by slackening font banjo bolt on injection pump.have you reset tappets?

Do you mean where the pipe goes to the filter head?

Valve clearances !! Take the top rocker cover off , get feeler gauges ! Find a ten thou feeler , put a socket on the bottom crank nut , look for the rocker that is lowest down !! Count upto nine and insert the feeler under the rocker arm!! Adjust the gap until feeler slides nice and snugly!! Do all eight valves slowly and carefully !! If in doubt double check all clearances !! Put the le Iid on using a smear of sealant !! Do this while the engine is cold !! Done correctly the engine should be nice and quiet ! And smooth running !!
Good luck .
