Engine Ticking Noise

I would just live with the tic......just keep watch...
run injector cleaner every 2 or 3 tanks.....
After market injectors have big holes and dont clog as much.....
they dont combust as effectively as the the toyota oem injectors.....

The real toyota ones have many more tiny holes......hum......
and they need cleaner even more so than the big ass inefficient ones....

I'll get pic up of the 2 different styles.....



Here's the one's you dont want......




Denso exert........ , Denso introduced the 12-hole injector in 1999. Its breakthrough design reduced fuel droplet size to 65 microns, providing superior atomization for improved engine efficiency. In 2002, Denso followed with its UC injector, reducing droplet size even further, down to 50 microns more details on - https://www.carid.com/denso/fuel-injector.html#features

 

The good ones.....

 

As I usually fall victim to this, but in the opposite direction, OP has a v6, and I think the injectors you pictured are for the I4?

I know my stock injectors did not look like these, nor did my MotorWest "upgrade" denso injectors.

 

It looks like all 3 engine sizes use this individual injector (98-2004)

$70 23250-75080 4Pcs

23250-75080

looks to be about $150 a piece for the real one......
about half for premium reman denso's.....
and 1/3 or less for all the questionable rest......

if you order supposed real one off ebay....there's about 50/50 it wont be....
and just as bad - if they drop ship it from china, when u think its comin from Omaha... - you get 6 mo later....maybe not even right one......
