Oil Pressure
Oil Pressure
Just a quick question, but i was just wondering where the oil pressure gauge in our lx470 should be at during idle. In the middle, or higher the better? Sorry if a stupid question, i just really don't know
factory oil pressure gauges are no more than a guess to show that there is oil pressure... (funny note, but in most fords, the oil pressure gauge goes to the middle as soon as there is voltage to it, it is not a gauge at all, it is a oil pressure switch)...
anyways, so long as the oil pressure gauge is above the bottom, there are no worries... if you want an accurate oil pressure, you will need to buy an aftermarket gauge... the oil pressure warning light will come on on the dash if oil pressure is below 5 psi...

Ok, so i just checked it, and the oil pressure gauge is about a quarter between the bottom and the middle, just had an oil change. If you don't mind me asking, what could be a cause of a low oil pressure
as far as oil pressure - well, first off, if there was no oil pressure or less than 5 psi and the warning light is on, most likely cause is low oil level...
as far as just low oil pressure, three things can cause that typically - most common is worn main bearings, next is worn oil pump, then one more possibility is that the oil pressure overpressure valve spring is loose or worn, allowing oil to bypass... Honestly, I don't know if the 470 has that overpressure valve, but afaik, most engines do or have something similar...
Yea, the oil pressure gauge is nothing more than a dummy gauge. It simply says "yes i have pressure" or "no something is wrong"... This is why Lexus has steered away from using gauges, and just using lights. If the gauge moves, you're fine 
Hate to bring this back, but what if the oil gauge is higher, bout 1/4 from the top on starp up, could this have something to do with a certain smell i have been experiencing from what smells like the left front of the car? I thought the smell could be caused by a muffler and exhaust pipe that needs to be replaced but idk

No leaks anywhere, oil is never overly brown in a short period of time, 93 octane gas only used, always dealer serviced, and today i started the car, turned it off, then started it again, oil level is where i thought it should be and the smell seemed to be reasonably less or even gone. It is definitely coming from the front left wheel area, but there are no performance differences, no still averaging 14 mpg around town, all fluids are the same, i can't stand thinking about what the smell is coming from

It's definitely not a plastic bag, had both manifolds replaced in the spring, doesn't smell like gas and no smoke is coming from the exhaust or anywhere, no strange noises, but it does smell stronger when it is colder and it may be a mental thing, but depending on how much gas in the tank or where we get gas, the smell is stronger or weaker. I guess the smell i could best associate with the smell of a zamboni while resurfacing the ice....if you know what that smells like. As i said before though, after the initial start up and shut down, then start again, the smell is much weaker if not completely dispersed
