Guys, need some advice.

My Singapore VQ20 overheated recently due to the radiator bursting.
I bought a foreign used radiator and replaced it.
Got a mechanic to do a check and he said the car was ok.
No water being thrown out the radiator, no mixing of oil and water and no bad fumes from the exhaust.
I drove the car for about a week as usual, with no issue then out of nowhere the radiator burst again.
This time I took it to another garage and they put in another radiator, but now the car won't start.
They checked all that they could and they just could not get it to start.
They took it to an electrician that said the brain and harness were burned out.
Now they advised me to buy an engine with brain and harness.
That is quite a costly fix, especially as the car is for sale.

Any ideas or suggestions before I spend close to $10k on this job?

a brain and harness wont cause a radiator to burst, It will prevent it from starting. I suggest you get another mechanic to take a look at the car.

The issue was that I did not get the thermostat removed. This eventually blew one of the heads. The back bank. I did change the engine and the brain and harness in the process.

Morning Guys ,
I am having a little trouble with my VQ 23 for my Teana, I am hearing a whinning \whistling noise between the speeds of 40-70 km\h. the noise is intermittent and only happens when i am mashing the accelerator. I have tried changing the belts, idler pulley. checked for belt deflection. I have also removed the belts and spin the PS pump, alternator, A/C compressor by hand looking for a hard spot. All to no avail. It only happens when the engine is under load.

Any suggestions as to what i can check again is welcome. I will start to lose my hair just now if i cant figure out this problem

Folks, i've decided against selling my VQ30DET and I want to put it back together. I need the brackets from the front to hook back up my accessories. It was removed to check the timing chain and misplaced. Think the VQ20/25 might be the same. Here is a pic of what mines used to look.like.

White smoke and burning oil. You need to get that checked immediate.
Worst case scenario - head cracked and oil seeping into the cylinders.
Not so bad - Rings are gone and you need to change them and machine the cylinders.

Isn't that symptom related to bad valve stem seals?

Change the oil and use an engine flush, put a thicker body oil.
