This often occurs after the oil pan is resealed where excess sealant is forced through the lube system (short circuit check valve) and trapped at the edge
filter of the high pressure pump.
5.) Abnormal Long Crank/Stall after cold start
A worn lube oil pump can negatively affect ICP system's performance in the following ways.
-
Cold engine, abnormal long crank to start. (Oil pressure gauge in dash moves immediately prior to start.)
-
Cold engine, start then stall - then long crank to restart. (Oil pressure gauge in dash moves immediately prior to start.)
These symptoms are often mis-diagnosed as high pressure oil (ICP) concerns. Both symptoms may be caused by wear in lube oil pump or thick oil (poor
maintenance).
Pump wear causes a decrease in pump efficiency. Cold, thick oil becomes to move.
Any lube oil system failure can negatively affect the performance of the ICP system.
Recession greater than .003" causes long crank to start and/or stall.
