running in

[tainer]

i have 2000 peugeot 406 and i just got a new head gasket fitted and someone said it needed 'running in' is this right.

if so how many km do i need to run it.

Not really if you have change the Piston rings, crank bearing, connecting rod bearing etc too then atleast 1000 km running in must.

Only head gasket sets in half an hour of first drive. Still better drive easy for first 100 -200km. thats it.

its better to be safe than sorry....if, at any time, on any engine, u replace a major part, take at least 1000kms to run it in...no more than 120km/h and no higher than 4000RPM
