The engine of my Lexus RX300 knocked on Monday

I eventually bought a tokunboh engine yesterday at Ladipo Market for 540K

Now I want to sell the old engine that knocked, what is the best price I can get for it?

Does anyone have any idea of a fair price to ask for or the current going rate for a knocked engine?

Hello everyone,

I recently installed an AC in my 2005 Toyota Camry, but I’ve noticed that the car vibrates excessively when the AC is running. While trying to diagnose the issue, the engine began making a rattling/grinding noise, and now it shuts off immediately after starting.

Has anyone experienced this before, or does anyone have suggestions on what might be causing these issues? Any help would be greatly appreciated!

Why don't you retrace your steps and replace the compressor with the right one?

Greetings everyone,
My Toyota Camry 08 is making some noise on cold start but the noise vanishes after the engine gets hot.
Two mechanics I've ed both said is the timing chain.
But one said it needs adjustment while the other said it needs replacement.
Kindly advice what to do.
Thank you all

Replace the camshaft with the updated one and you should be fine.
Please do not weld it if suggested to you.

We later discovered it was due to a bad top gasket and it was replaced with a new one and car runs fine now.

Good to know your car runs fine now.
Curious to know how an AC job led to rattling and grinding noise and then gasket

No ask this kind question bro, no loud am. If you know you know.

"The previous air conditioning system in the car wasn’t functioning, so I had to purchase a new compressor. After buying the car, the seller mentioned they had recently replaced the engine. However, I suspected the engine might have had a preexisting head gasket issue, based on a past experience: once, after installing a replacement engine, it immediately began making grinding noises and vibrating violently, which turned out to be a blown head gasket. Given that history, I decided to check the head gasket on this engine as well—and sure enough, it was faulty, so I replaced it.

Is this the head gasket you pulled out from a supposedly tokunbo engine?
