Loud lifter tick after injector install

[crespoh69]

Hey guys, first of all just wanted to thank Martin at MotorWest Performance, the injectors seemed to have fixed my injector code issues!

I did the Denso performance injector replacements, changed out all new gaskets, new crush washers and a few new hoses as well, the car even started up after the initial crank and it only took me a the later part of yesterday and today to complete and I'm mostly happy. The power was severely lacking on this V6 and I didn't even know. Now it really seems to pull and there's no shuddering of hesitation any longer, I even tested it out by driving to LA, turning it off for a few mins and turned it back on, no shuddering at idle.

Now the downside though. One very noticeable thing is the lifter tick. It wasn't there before my install but now it is and it's very apparent, even inside. What could have caused it? Like I said it only sat about a day in all so it wouldn't have been gunk I don't think. Here's a video to show how apparent it is: Shared album

It's the Toyota tick. Some injectors are very loud and sound just like a lifter tick. Harmless, drive happy!

Yup sounds like injector noise. I have an even louder fuel injector on mine.

I had this happen with my 04 Ram/Cummins. The shop that installed the new injectors couldn't isolate the loud injector so they replaced them all under warranty. It's quiet and runs like a top now.

The Toyota engines are famous for sounding like a diesel.

use a long rubber hose or buy one of those stethoscopes at Harbor Freight. Find out which injector. talk to the injector shop see about replacement.
However they ae a flow matched set...well at least that is what is advertised last I looked.
Installed a set of his about a year ago and have had NO issues

Thanks, it's definitely not affecting driving performance, just wanted to check in with those more experienced than I before just ignoring it. Next thing that's bothering me is what sounds like a vacuum leak as well as a rattle while initially stepping on the gas, it goes away at WOT and after more than slight pedal depression.
