SoCal Nissan Repair shop suggestion

[RiversideS13]

Hi, the 91 240sx that i recent brought had loud ticking noise on the engine and after searched here, i believe it was the timing chain guide is bad. But at same time, the car timing was also off that it runs very rich. So i am guessing the timing chain had loosen problem since it had 195k miles.

can anyone suggest a good nissan repair shop with good price in southern california that know Ka24de very well?

thanks,

I am locating in riverside.
