Ticking sound coming from engine bay.
Hey everyone,
I just got my first 1993 jeep wrangler, its a 2.5 4 cyl.
its in overall good condition, but im hearing a ticking noise coming from the engine bay.
Do any of you have any idea what that might be?
I was told to use a stethescope ( sp? ) to pinpoint the location of the noise. I put the stethescope on the valve cover, and i heard alot of noises. Im not too sure if it is the exact noise, because the valvetrain has alot of parts moving around.

Thank you in advance.

lifters maybe??
sometimes happens when the oil is getting thin..
maybe give it an oil change and see if that helps.

Yeah, sounds like a lifter is tapping. You might wanna get that checked.

X3 on the lifters, how many miles does the rig have?

97REDTJ 10-31-2006 06:52 AM

x4 on the lifters. When i first got my 89 yj it had some ticking noise. We messed around with it for a while and finally found out it was the lifters. They dont cost all that much but its alot of work for those little things.

has 88k, origanal. 3k on the new head.


Wrangler93 10-31-2006 10:27 AM

This may be a dumb question, but since its a 4cly. Can it do any sort of offroading?


Dare2BSquare 10-31-2006 11:04 AM

Darn straight it can. A Jeep with a 4 banger is a capable 4 wheel vehicle. If you are going to be hardcore, you will need some mods.

You may also want to take a look at your exhaust manifold. A leak where the manifold meets the head will also make a ticking sound.

94redwrangler 10-31-2006 11:59 AM

hey man i have a 94 wrangler. and on mine i had a horrible ticking sound and i found out that is was coming from two places the donut and at the manifold where it meets the head. from what i have been told is that the very last manifold bolt is very weak. and alot of them will break off. i have ordered a new header and cat back exhuast kit.and i am getting the bolt tapped out. i don't know if that helps but that is what it was on mine.

BUMP!! the exaust manifolds are famous for cracking, the only thing good about yours is if its a new head the nuts wont be rusted on the studs so it will be an easy swap to put in a header!

rebelBullDawg325 10-31-2006 03:48 PM

it's most likely an exhaust leak.... does it go away as the engine warms up?

Wrangler93 10-31-2006 07:34 PM

i think it does actually go away slightly when the engine warms up.
it takes a while to go away, but i think it does. And, if it doesnt go away, its very..very very slight.
how do i check to see if it coming from the manifold?
and would putting headers on this car do anything? i have a 79 trans am as my fast muscle car, i do not need this jeep to be fast by any means haha, but any nice jump in power is appreciated.


Wrangler93 10-31-2006 07:36 PM

AND, sorry i forgot to post this, but. 94redwrangler. What do you mean, donut. you said two places you had the tick. donut and manifold. do you mean the donut tire?


Angler1979 10-31-2006 07:41 PM

by putting a header on your jeep it will allow it to move exaust gasses out of the cylinder head faster which will result in more horsepower, and tourqe the 4 banger needs all it can can get expecially when running larger tires.

Wrangler93 10-31-2006 07:56 PM

if it is an exhaust leak. Should it go away really fast when it warms up, or will it just quiet.
When i first start it, its pretty loud, you can tell its there. But after a while, its like reallllly quiet. And im not sure, but i think its gone. But, it still might be there.


amerijeep 10-31-2006 08:09 PM

I think he has a dozen donuts on his seat and they are ticking.

94redwrangler 10-31-2006 08:39 PM

the donut is where the head pipe connects to the rest of the exhaust. or thats what i have always called it. it is a flat piece of metal with three nuts and bolts holding the two pieces together. sometimes they will rust and break or there might be a crack there.

Wrangler93 10-31-2006 09:03 PM

well guys.
The noise doesnt go away. at all.
Not even to the slightest imagination.
I started the jeep up, it was there, and fairly loud.
Then, i drove it around, got her nice and hot. And the noise got a little quieter, but was still there never the less.

So, you guys think its the lifters?


Wrangler93 11-01-2006 10:32 AM

well, i think its a knock now.
I took it into my shop class today, and we were looking at it, and it seems to be knocking, not ticking.
but, i can not find where it is coming from. i used a stethescope, and searched everywhere on the block.


timmy43410 11-01-2006 04:50 PM

The tick might have been the lifters...a knock could be something a whole lot worse. Pray its not coming from the bottom end inside your oilpan.

Angler1979 11-01-2006 05:06 PM

pull the oil pan and check the conecting rods, is there any fluctioation in oil pressure during all rpm ranges?

Wrangler93 11-01-2006 06:56 PM

my oil pressure goes up to around 50. when im driving on the express way, and when i get off the expressway, it goes back down to 40. or wherever the middle is.


Wrangler93 11-01-2006 07:35 PM

does that oil pressure increase, mean anything?

daddyjeep 11-02-2006 11:13 AM

Mine comes up a bit during acceleration, i don't know if this is a problem or not. Mine has been this way for years.

Angler1979 11-02-2006 12:03 PM

it is normal for oil pressure to rise during acceleration because the more RPMs you have the faster the Oil pump pumps creating more pressure, when you rev up the motor and the pressure gage stutters or even drops you have a bad oil pump, and the end is near unless you take action.

Wrangler93 11-02-2006 03:45 PM

well, its at the shop right now, getting its final check.
We believe that the motor is taking a crap on me, and im looking into a new one.
I found a brand new from the factory motor, direct replacement for my jeep. for 1,500.
i think im going to go ahead and take it.

what do you all think?


Angler1979 11-02-2006 04:21 PM

that sounds fair thats problibly just the long block, your going to have to change over all the external stuff like exaaust manifold, intake manifold, alt, Ext... when you do the motor swap its an exelent opertuinty to install a header!!!

Wrangler93 11-03-2006 10:25 AM

Well, actually, the engine comes with everything, EVERYTHING, but the alternator,ac pulley,powersteering and tensioner pulley ( sorry, spelling sucks )
So its a great deal.
I can just transfer all those accesory pulleys over, right?
