I'm swapping out the cam/oil pump on my 4.6. I went to install my old timing cover from the 4.0 it's replacing along with new oil pump. These wear rings make me nervous. Think I should find another cover?

 

I would replace just because it's a once and done sort of thing and we know how much Rovers love their oil pressure. Any idea what the oil pressure was like on the 4.0? That would be my decision mark.

 

That's the timing belt cover. You probably have a leaking oil pump or cam seal. The cam seal would be directly over that spot. The oil pump is behind the crank pulley but if oil is leaking g it will spread along the bottom of the cover. It also looks like you have a valve cover leak and possibly head gasket /upper oil pan leak. Nox Vidmate VLC Hard to tell by the angle.

 

having just changed mine (SW Rovers) I got a schooling on the oil pump cover and I would say this one is really past re-use - search out another without the heavy scoring - discoloration is ok and light scuffs ok but the deep groves are a no go

 

Um?? What? Lol there is no timing belt. And the timing cover has the oil pump housing cast into it. There is no cam seal. Upper oil pan??

​​​​​​Gents I wound up not using this cover

 

Did you buy a new one, or used? There is a specification for the gap between the two moving parts. That is probably the most important to get right.

 

I used another I had. I had a few laying around along w a new oil pump. I haven't had any oil pressure issues

 

what is your oil pressure - cold / hot ?

 

​​​​​​When I had the gauge hooked up around 10-11 or so at idle. Then around 30 at 3k engine warm. Running big ol Mann filter and Rotella 15/40

 

Just as a comparison... After a complete rebuild (March of 2018) on my 4.0 I get (today) 22 PSI at warm (160-180F or 70-82c) idle and 40psi at cruising speed with 15/40 Rotella so those numbers aren't bad. I also used a timing cover that came off a junk yard car that was smother than mine, not smooth, just smoother than what I had. I have a mechanical gauge connected and routed on my dash, temp too.
