taco tick noise

Hey all, new to the forum. Just wanted to ask if this sounds like normal taco tick or if i have a valve or injector noise. My truck is a 98 5 speed 3.4l v6 with 268,000. It's most noticeable at warm idle, and either stops or engine drowns it out above 1500 rpms.

 

Sounds like the normal tick to me

 

Really? I thought it was a little excessive. Sounds a bit like a deisel. What causes it to tick like that? Btw thanks for the reply

 

Pretty sure it is injectors, even my four cyl just ticks away at idle. Can't hear it at any other time

 

They all do that man

 

Thanks for the reply. Its nice to know I'm not the only one

 

Maybe the valves are a bit loose???

 

Could be you need an oil change...the lifters seem to quiet down when you get your oil changed.

 

my 95 has done that for a while, ran some sea foam through the system and it helped but it's back again

 

Mine does it too. Seems to go away for a while after an oil change.

 

Crank case or gas tank

 

I actually just changed it

 

Yeah, the posts suggesting the oil change seem correct. I changed my oil yesterday and noticed this morning when I started it, it sure was quiet. Was my first change, so wasn't sure if it was the weight of the oil or quality of it or what. I'll know more by next change, in spring hopefully.

 

What kind of oil (weight and synthetic/dino)?

 

Your injectors do make a very faint ticking noise, but what you're likely hearing is the EVAP VSV. It's located on your EVAP box on the driver side and ticks at low rpms. Put your ear up to your EVAP box and I'll bet that's the source.

 

Ummmmm, ummmmm.... You should follow the manufacturer's recommendations on oil weight and I like Mobil 1. It's inexpensive at Walmart.

 

Ok guys thanks alot. Just one more question. Why is it so audible from the wheel well and from under the truck?

 

If is what he mentions :

It's located right by the wheel well under the hood.

 

no lifters to be heard

 

Ok I will check it later. I remember hearing like a vacuum type suck noise from the charcoal canister but it might be it
