There’s a weird cranking noise that sometimes emanate from the engine of my few months old RX 350 (2009) Lexus. Bought the car directs Tok and engine is still very sound . I usually notice this weird engine noise whenever the vehicle is parked for a few hour’s especially on hot afternoons


My mechanic said it happens due to oil circulation when you start a car and its normal.

Another mechanic told me it could be that the filter under bottom plate is dusty or it could be that the chains in the engine need to be adjusted. That I should bring it for him to access it .

A friend who uses ES 350 is also experiencing similar issues and his mechanic said it’s the oil circulation when a car parked for a few hours starts

I’m still not satisfied with the mechanics response

I use the normal Mobil sold 9500 at Mobil stations and I’m thinking of switching to Mobil 1 hoping that would correct the noise. A colleague using RX350 uses Mobil 1 and has never encountered issues like this with his car



Please I need the views of experts/engineers in the house

Anybody here experienced a similar issues before ?

I use the same car, am interested in reading the answers.

Hnmmm

why are you using OW-50 for a Lexus RX350 though. You should be using at least a 5W-30 semi synthetic oil (though dependent on what the last user was using).

Scan the car and post codes.

I don’t think a scan can point to this.

I will suggest you open the bottom tray like suggested and clean the oil pump filter.

That is the first cheap fix

Oil pump is blocked..rem ypur engine is aluminium

look for kingreign on auto section, the guy is good, if you in Abuja

Read the post and start from the op fix first before opening engine

I used a fully synthetic Mobil oil when I serviced last week and the noise stopped .

Is it okay if I use 5w 40 fully synthetic oil?

No use the recommended oil. Not 5w40
