Well my 98 xj is running funny my engine is makin a ticking sound not a knock but tick tick tick tick tick... cold or warm it makes this sound now my oil pressure gauge is a lil above 40 when I first start it then if im not on the gas the oil pressure gauge goes down below 40 then when I get back on the gas it goes back up to 40 or a lil over 40?? And then to top it off my temperature gauge will be at like 195 degrees then shoot up to 210 maybe 220 then go back to around 195 or stay at 210?
I feel like somthing is wrong with me jeep and idk what it could be the ticking is getting to me I hope its not my oil pump someone please gimme some ideas thank you

 

Could be millions of things. Try to figure out where it's coming from.

 

I have been tring man sounds like upper right side so therefore sounds like my oil pump huh'??


But yo people say jeep tick could this be wat they mean? Ima put new oil in her right now then see how she is;( any ideas pleaase lemme know thanks Bro

 

Sounds like a lifter, or rocker arm BTW your oil pump is at the bottom of the engine. The oil pressure going up when on the throttle is normal, it will lower once it warms up and the oil thins a little, the temp will flucuate especially at a stop light it doing it at stop lights? or while moving? if its doing it while moving may be water pump, When it goes to 220° your efan should kick on so youll see it drop.

 

Could be a lifter, rocker arm/pivot, and in my case, a pushrod.

 

Thanks guys and also its while im moving slowly so idk ima get it checked out thanks

 

Sounds like sound is at bottom on driver side front??

 

Nothing there but bearings!

 

It's normal all jeeps do that at some point

 

Listen around the firewall. I don't know about on a 98 but on mine there is an evap solenoid on the firewall on the passenger side, and it ticks really loudly.

 

Mine makes a bad ratle noise at low idle; then stops when I rev it up. I think it's the flexplate. I saw a video on youtube whre another jeep did this and the noise was exactly like mine.
As I understand it, flexplate problems are common on the early Cherokees.

 

Yeah mine ticks pretty loud is that normal ?

 

if it quiets when warm consider exhaust leak from manifold or gasket or downpipe connection. the metal warming up causes expanding which in turn lessens the gap and reduces noise. mine turned out to be a bad seal at the downpipe and manifold.

 

you could have a air bubble in your cooling system, causes similar problems. i would agree that you may have a lifter/rocker/push rod/valve adjustment problem, or it could be that you just never noticed the sounds before my heep makes all kinds of noises when i shut it off it sounds like it has a rod knock. 270k strong i still rev that thing to 5k well it does it to itself but you know what i mean. i have always said dont fix it until it breaks

 

My jeep made a tapping noise at idle.I pulled motor last week to get rebuilt & it was my flexplate! Cracked all the way around n ready to fail in a few hundred more miles. Check your flexplate. Cracked exhaust header maybe. Does it tick throughout the rpm range or only at low rpm? GL
