I've just been watching a video on YouTube discussing the front cover. I think it was Atlantic British.
The guy described each part of it and listed a few common issues that arise in that area. One of the parts that he mentioned was the oil pressure relief valve. I figure that its job is to release oil pressure when it gets too high. Is that right? Does it release the pressure by squirting the oil out of the engine or back in to the sump?
If so, if/when it fails could it possible lead to low oil pressure at idle but when the engine revs it produces enough pressure that the sensor reads OK again?
I'm wondering if I've gone a bit overboard with my low oil pressure at idle issue (I've ordered a set of new pump gears and a timing chain kit) and perhaps my relief valve has failed.
There's no procedure for replacing it in RAVE under the Engine > Repair section but it is mentioned in the Engine > Description section. I also can't find a part number for it on the LRCat, Bearmach or Turner Engineering websites.
Is this a serviceable part or is a case of replacing the whole front cover?
