2003 4.6 engine camshaft thrust plate problems?
Hey there,
I have a nice rattle on start up that decreases in sound intensity as the engine/oil heats up. I doubt it is the oil pump as the oil light (pressure) is not on.
The sound is not on the top of the motor (lifters, pushrods), nor does it sound like rod-knock (which is always there and gets worse over time and increase in RPM).
My two main catagories are either the oil pick up rattling loose, or the camshaft thrust plate. I have a Bosch motor, and I believe the 4.6 has this item.

Anyone know about if the thrust plates get worn or rattle loose (bolts loosen)?
Regards,
Jonathan
Here is a photo of a similar set up for reference:

I might be stating the obvious, but the diagram you posted is showing the TDI engine?
I'm not seeing the thrust plate on this diagram or parts list, but then again, this diagram doesn't list the 4.6 either.....http://www.roversnorth.com/store/c-598-lower-end.aspx
P.S. - I see you're from the Boro, I'm an MTSU Alum. Go Blue Raiders!

Per your link for the rover engine parts, I concur that the part #51 (camshaft retainer plate a.k.a. "thrust plate") is only for the 3.9 and 4.2 liter motors.
However, if you dig further and click on part #51, it takes you to a link where if you go back one you find the plate for the 4.6 liter motor:

by the way, I hate MTSU. Hopefully they will have a parking garage completed within the next two years.

The sound is puzzling. It sounds like a rod knock on start up, very loud and clacky. However, the sound fizzles away after the engine is warm and is incredibly hard to hear at all after driving around for 10 minutes (oil hot). Every single rod-bearing issue I have ever encountered it was loud clacking through the entire RPM range and the motors never lasted long after that.
Maybe its just the oil sump tube loose, per my indy mechanic (he is a BMW master tech and loves to work on Rovers, he had one and loves their durability and alike).

The photo was for reference, but actually part #4 is a thrust plate, and yes that diagram is for a TDi.

And sorry you feel that way about MTSU, parking sucked bad enough 4 years ago I can't imagine what it is now
Good luck with your fix, hopefully it's something simple.

I will shoot BPUtah an email. I already ordered a gasket kit to fix the front cover oil leak I have (and valve cover leak). I guess I should go ahead and replace the oil pump gear just in case when the front cover is off.
