You posted this in the "Cherokee forum questions and suggestions" section, which is for questions and suggestions about the site itself. For example if you have a question about how to create a thread in the appropriate section.

I moved your thread to OEM Tech, which is for questions about stock parts and workings.

Getting to your issue...

What weight oil did you use?

 

thankyou for that. i used a valvoline 10w30 synthetic in it

 

How many miles are on it? And did the previous owner always use full synthetic?

 

has 95xxx miles and not sure about previous owner use bought from a car lot

 

Why'd you put Lucas in it?

 

thought i was taking care of it

 

Usually on an engine thats a little older. You would want to use the same kind of oil in it thats always been used in it. If possible, find out what the previous owner used, and try using that.

 

okay thankyou

 

Also, what brand of oil filter did you use?

 

used a puralator .just changed it again put regular 10w30 in it with a mobile1 filter now it just ticks loud at start for a few min.then tics of and on makes no since to me since it didnt tick at all before oil change thought i knew how to change oil lol

 

Next time you start it and it ticks, shut it off, wait a few seconds and re-start. Still ticking?

 

Thats weird my truck has 138000 and am on my second synthetic oil change and i have no weird noises mine runes better than with conventional

 

The Lucas was probably a mistake. Too thick.

 

I'm curious too, mine does the same thing. I had a friend say it was something in the valvetrain
