Loping Idle

[dboyw]

Last weekend I replaced the pedestal due to an oil leak. Replaced all four o-rings also. I also installed the SS X-Over line. Changed oil at same time, from Amsoil to Shell Rotella, due to next few changes are going to be short intervals.

Everything seem to run and sound great, but the engine seems to also have a lope in it. Very steady. About 102 beats per minute at idle, 750RPM.

Truck still drives fine. Floor it and she moves. I just do not remember this being there before and wanted to have it diagnosed.

Thanks in advance.

You may still have some air in the HPO system. How many miles since you've installed the crossover and introduced air into the system?

Some trucks take 50 miles or so, driving it harder will also help purge the air out quicker since the harder you drive it the more oil volume is pumped by the HPOP.

Drove it to work everyday this past week, 30 mile round trip, highway. Never really floored it though. I'll try that this week.
