Hi All
After fitting the forged pistons and rods ,all went well until a noisy lifter started, any how decided to buy new set of lifters and again head gaskets, going to fit these in
However I have a disc called Dodge Challenger 2014 P/no SN 953917AA this shows me the complete tear down and rebuild
Firstly.......... on fitting the rocker arm back on the 5 small pillars on the head you then slowly torque down, and follow the torque sequence
what does confuses me a bit is the instructions are hi lighted:-
CAUTION :
Do not rotate or crank the
engine during or
immediately after rocker arm installation
Allow hydraulic roller lifters adequate time to bleed
down (after about 5minutes)
Not sure here ?? their`s no oil there to bleed down if they are new surely!
am I reading this right ??
To follow on with this prior to doing the rocker arms etc., when you fit the head gaskets it tells me this:-
NOTE:-
Rotate crankshaft 45 degree's so that all pistons are 1/2 the way down the cylinder bores to avoid piston to valve contact.
Please correct me here! is this telling me that the cam is at its lowest points to allow the rocker arms to be more easily fitted
so you can torque down and not put too much load on one or two of the value springs.
Would this also not squeeze down the new lifters too harshly
Help and advice here
Thanks all for reading this
