Default Help needed. Cam cover plugs missing

Can someone help with a pic of their engine bay with cover removed?

looking at a RX450H engine bay and notice there are two plugs on the cam cover are missing, try to trace it back to the loom.

it seems someone replace a different loom as there are few screws aren’t done properly

car had front end repaired

Two plugs missing connectors

What year is this 450h? Here is some pictures I have from previous repair jobs of a 2010 and I can’t find those connectors. Maybe they engine swapped the wrong type of engine? The 450h came with a 2GR-FXE which uses an Atkinson cycle.

Actually I think that’s what happened. They swapped in a regular 2GR-FE which is used on a non hybrid model. The last photo is a picture of my 2010 ES350 with a 2GR-FE. You can see those exact connectors on it.

my car is 2009.

you might be correct. the wiring on your second last picture is what i have.

this may also explain why one of the wiring case can not be secure to the cam cover...

the cam cover must been swapped, rather than engine as a whole?

You need the whole engine. It runs on a different combustion cycle so it needs different sensors and may have different internals in the heads. At the very least you would need different engine heads.

2GR-FE: Otto cycle
2GR-FXE: Atkinson cycle


Does this engine run? I’m surprised it was installed with a wiring harness that can’t accept it. Somebody didn’t care or didn’t pay enough to repair it properly.

I'm actually surprise that the engine is running and drives too! it operate 90% normal, but not as smooth as what a Lexus should be.

i suspect that the cam cover has been damaged and the repairer just use the 2GR-FE valve cover rather than replace the whole head.

i'm looking at ebay and thinking just buy the correct cover and see what happen.

Hopefully that’s all it was but you should really find out what type of engine is in the car.

Was this repair covered by insurance? If so you need to file a complaint with your or the offending driver's insurance that the repair was not performed properly because they installed the wrong engine. You may get better results contacting your company first and they will go after the offending driver's company. and thus the repair shop.

"update"
i have source the 2GR FXE cam cover and fitted.

so previous repairer did a sh^%^&it job may be it was damaged/crack and just use a normal 2GR cam cover.

Car is running smoother and as what a Lexus should.

Thank you for your help
