Default Whats the ticking noise comin from under the hood

i have a 2002 ranger XL 2.3 4 cyl and theres an annoying ticking noise that is consistent. the only time it seems to go away is when i accelerate. my friend who is a mechanic for Mazda (who makes the ford ranger engines) says i need a new intake manifold. he may be right but i was just wondering if anybody else out there has had this issue and what the problem was.

it may be valve tap... i forget how but you can test the distance between the valve and some other piece and if its too large it will make this annoying tapping sound. happened a bit on my 94 yota pickup

fuel injectors doing their job. you can't hear it when rpm's go up because overall engine and road noise gets louder than the injectors. my 4.0's injectors are LOUD.

Default Re: Whats the ticking noise comin from under the hood

I have had the same exact 2002 ranger 2.3L since I bought it new. It always has that natural tick....but......lately the tick is much louder at start up. it does tend to go away after a few seconds and the RPM's go up. Obviously there is something changing. I was figuring valves as well. Is there a way to test that theory, since I don't have a mechanic shop but do have enough balls to try some engine repair? Thanks for any help.

Bob

You need to get a stethascope and determine where the noise is coming from. Ie. Lifters, injectors, crank. In the mean time add some tecron to the tank. Seafoam thru the brake booster and change the oil to full synthetic

Default Re: Whats the ticking noise comin from under the hood

I have a 2001 with the 2.3L and it has had a similar ticking since about 100K miles (207k now). It only happens under 2000 rpm and disappears under light throttle. When you hit 2k rpm it's as if a switch was thrown and the noise quits instantly. It seems to be coming from under the intake manifold which leads me to believe the injectors are the culprit. I have always used Lucas injector cleaner, about every 2000 miles and my gas mileage is good - 27mpg average, but the noise persists. I just replaced the pump and the filter has been changed regularly so the fuel system is in good shape. Oil pressure looks good, but I am not sure if I have the "dummy gage" that only registers if less than 7PSI? Do you know if we have the fake gage? Thanks

Dave

Thanks for the info. To be honest, I had no idea what Seafoam was until you mentioned it. Watched a bunch of youtube videos on it and did it yesterday. I am planning on letting it run for the week, and then changing the oil this weekend over to full synthetic. I always go to Chevron for gas, so techron runs all the time.

The ticking is still there, but it sounds like a regular issue with the rangers. I just hate having something like that happening. Maybe I should run seafoam through the gas tank and crank, or would that not really help?

Appreciate the help.

Sdbob since you use techron all the time you don't need to put seafoam in the gas. Put 1/3 can in the oil for a couple hundred miles and do the 1/3 of a can thru the brake booster twice. Then change oil. When doing the brake booster don't let the truck stall. Occasionly it will foul a sparkplug but yours are easy to change

What does the Seafoam in the oil and thru the brake booster do? I suspect in the oil is for a noisy lifter? We used to use some ATF in the oil because it had real high detergent content to clean everything.

Thanks

In theory the seafoam through the BB helps clear out Carbon, etc the carbon can foul a plug. I know it helped my engine when I used it. I use to have a lower end crank noise which cleared up significantly after using seafoam

I am running Auto-RX in a 1998 Saab 900S right now.It seemed to quite a little lifter noise I had at startup. I will swap out the oil filter in 800 miles. I plan on opening the filter and if I think it worked I plan on running it in my Ranger 2.5.
