Low oil pressure

Hello all, this is my first post on this forum, although I've been reading it for a while now. I have a 2001 Camry CSi, 4-cyl auto that I recently picked up very cheaply. The car has done 191,000km with patchy service history. I pulled the cam cover off recently and found the expected black sludge everywhere, so I decided to put a flush through and clean the motor out. It was reasonably quiet before the flush but with a bit of a grumble and a buzz, which I thought was probably lifters. After the flush and with fresh oil and new filter, the enging is beautifully quiet and smooth, but is registering low oil pressure on the dash. I've pulled the sensor out, cleaned it with carby clean and ensured it is getting oil to it, but it still registers low pressure at idle and when given a rev. Pressure was fine before the flush. What puzzles me is the quietness and smoothness of the motor; it really sounds like everything is well lubricated. Needless to say I haven't driven it anywhere and am yet to actually measure oil pressure with a gauge, but does anyone have any ideas on where to go first from here? I reckon I'll have to drop the sump and check the pickup shortly but what could I do in the meantime?

Thanks.

Ben.

About 4 litres has gone in so it should be right...

4L! thats a tad too much for a 4cylinder 2.2L isnt it!

usually its around 3.5 to 3.75 max max. and even then its cutting close to overfilling.

i might be wrong, but i placed 3.4L in to mine and it was just right.

I wonder whether the engine flush caused all of the engine sludge to dislodge simultaneously and cake-up the oil pickup screen. If the screen is blocked, that would cause low pressure. I guess the only way to know would be to pull the oil pump and have a look.

I usually put exactly 4L into my 5sfe Celica (with oil filter change).

Pull off the bottom oil pan and inspect the pick-up screen... most likely its lodged with sludge.

if that doesn't work you can always clean up the top end then replace the oil pump behind the timing cover if the sludge is not too severe.

Problem solved - I got hold of a pressure gauge and checked the oil pressure which turned out to be fine. A new sensor later, everything's great. Thanks for all your replies. And by the way, the oil level is spot on.

Considering also it's a V6, with two heads, and two extra cylinders, no wonder it takes more oil than a 2.2L 4cylinder....

      Toyota Corolla 2012 zre152 transmission issue

      Hi Toyota owners, I'm new to this forum registration. I need some advice or help as I have a shifting issue with my 2012 4 speed transmission. It doesn't do it all the time but the gears don't shift smoothly specially 3 to 4 gear it just bangs in when I'm cruising and it happens more often when hot. Got full transmission serviced with Toyota genuine parts no metal shavings in pan. Changed ATF 3 times. Full major service done, 100000 KLM on car. Full synthetic oil with 98 Ron fuel. Throttle body cleaned twice. Maf sensor cleaned. New spark plugs. No engine codes. Great loss of power sometimes specially on hot days. Please help as no mechanic knows what the issue is. Thanks in advance.

      Auto door locking on new 2024 C-HR?

      Yes mine is October 2023. It arrived late February Early March to the docks in Brisbane. I have a friend who has been told that hers will be in the next shipment but is only on the production line now. So future stock should be 2024 ! ?

      Auto door locking on new 2024 C-HR?

      Thanks Martin. I thought that may have been the case. However, it seems an anomaly with so much tech on board. My wife always looks for this feature after an ugly incident while stopped at a traffic light some years ago. As you said ...perhaps an OTA update? One other thing if you don't mind me asking. What is the build date on your vehicle? The C-HR's that appeared at my local dealer in the last fortnight all have an October or November 23 build date. Thanks, Peter

      Transmission U660e

      Not every Estima is fitted with the 2GR-FE and U660e drivetrain. This is where you have to take care that information on the internet is applicable to your specific vehicle.

      Auto door locking on new 2024 C-HR?

      Hi I was very lucky to receive one of the first new models last month. My Koba is amazing- as have all of my previous Toyotas. However in answer to your question it does not automatically lock the doors when you engage Drive or when you reach a preset speed. I am very disappointed that with all of the electronic devices and safety features and the approximately 20% increase in price over the last model that Toyota Australia has left a very important safety feature out of the vehicle. We see cars being carjacked almost nightly on the news. My knowledge of technology in this sector is limited but surely it is only an update of the operating systems to fix this. The new model is a beautiful car- your wife should still buy one.

      I rent a 2023 model in US just few days ago it’s beauty and real good on fuel much nicer to drive compare to Honda Odyssey which I own one 2022 model make me wonder why Toyota AUS won’t bring the Sienna hybrid to Australia instead we get bulky ugly looking Granvia with diesel engine 🤔🤔!!

      How to delete bluetooth device?

      I have a Yaris and had a similar issue. I just submitted a similar query to GPT. The response was to go into settings, view paired devices, select the device to remove, and confirm the removal. It helped me; I couldn't find the answer on the internet, but I found it there.
