RX450 2013 Knocking noise at start up

[pikeycockney]

Hi to you all,

                     Dont know if this has been asked before, but on cold start for the first 5 mins of driving there is a knocking sound coming from the engine. After that its fine.

Im think lack of lub, Is there any filters in the VVti pipe lines?

 

Many thanks for your help.

Have you the right 0W-20 oil?

[pikeycockney]

Its all lexus main dealer service,  so I assume they used the right oil.

Sounds normal and something mine did. Was told that it's to warm the catalytic converter up quicker

Had the car  into the main dealer, they confirmed there is  a knocking noise from the engine, no **** sherlock 🙂 

40 hours labour to take the engine apart and  investigate,  I informed them the car has a extended warranty, waiting to hear back from them.

I still  think its lack of lubricant on start up,  engine flush , new oil and filter, would be my first thing to do, but hey Im no engineer.

40 hours labour?  Surely that's around £4,500! 😱😵😨

Yeap, trying to fobbed me off with big ££££,  back there to pick the car up today, basically I said warranty - engine- not working- you fix, .......now maybe new engine, l watch this space!

I will watch with interest.  Hope you have a satisfactory outcome.

Stick to the new engine demand - since if they now decide they can fix it by changing something like the oil pump you have no idea what damage has already been done.

What's the mileage on the car?

[pikeycockney]

Yes I will,  I have closely read the warranty,  and its clear an engine is under the warranty 🙂  cheaper in the long run for them and a happier customer, 82k

If any garage offers you a "flush" you can pretty much prefix the term with the word "wallet".
