OIL Pressure drops, on my 08 5.7 Hemi motor, the engine sounds fine but something is not right with it. Is the sending unit my best option for fixing it?

Asked by MikeNorwood Jan 14, 2016 at 02:22 PM about the 2008 Dodge RAM 1500 ST Quad Cab LB RWD

Question type: Maintenance & Repair

My 08 Dodge 5.7 Hemi has and issue with the oil pressure dropping at highway speeds, when you slow down it seems to go back. Stopped checked oil it is fine and I am thinking it must be the sending unit, but I would really like to hear from someone more in the know then me. Can anyone help? The truck does have a lot of moles on it but has always had regular maintenance and has never cause me any problems.
Thank for any advice you can give. Mike

My 2005 Dodge Ram 4.7 is having trouble starting, it usually takes 3 attemps until it turns over. I suspected that it may be the check valve on the sending unit but I can find the part in online autopart stores which leads me to believe that it doesn't have one. Could it possibly be the fuel pump? 1 Answer

I have a 2007 Dodge Ram 1500 SLT with the 4.7. The plugs for the 4.7 have a reach of 3/4". I believe my mechanic may have installed the plugs for the 5.7 hemi which are 1" in reach. My truck went into the shop perfectly fine and came out with the engine knocking. Is it possible that the 1/4" difference in length caused the pistons to strike the longer, incorrect plugs hence, that caused the knock? The shop admitted to me that the wrong plugs had been ordered. When asked if it was possible that they may have installed the incorrect ones, they told me that the thread size wasn't the same. Well, truth be told, it is the same size thread. Thanks for any input! 2 Answers
