I have a 97 850 GLT and this is the first oil change I've done on it. After it was over, I noticed it was running rough and there is a ticking coming from the valves. Here is the steps I took when changing it, maybe you guys can notice something wrong that would cause this.

I warmed the car up and took the plug out.
I took the oil cap off to drain quicker.
Took the filter off
I used a filter from walmart, Bosch distance plus.
I put oil on the filter gasket and put it on.
Put cap on and filled car with mobil 1 full synthetic 10w30.

I think the oil is right. It is what is listed in the owners manual. I'm read afterwards of people filling the filter up before replacing it. I didn't do that.

Should I just completely redo the process and buy a new filter/oil?

 

Only one thing pops out to me. I presume by 1 full synthetic 10w 30, you mean a 5 quart container. I guarantee the car will take more then that. These engines typically like 5 1/2 and up. My buddy says 6 quarts, but each engine is a little different. Best thing to do is fill it up by the dipstick. My T-5r takes close to 5 3/4. My mothers s70 takes about the same.

The Ticking I wouldn't be concerned about unless it never goes away. My mothers s70 will every once in a blue moon tick after an oil change. It lasts maybe a few minutes and then it is gone. Also, just dont rev the car like crazy, keep the rpms down when it is ticking.

I will also say someone might comment about the oil filter you used. I have seen some people say a certain brand only. Hope that helps

 

It's got 6 qts of oil in it currently so it isn't that. I did just switch to synthetic so im thinking that could have something to do with it as well.

 

I doubt that's it. I have switched all of my Volvo's to full synthetic and have never had an issue like that.

I would change the oil filter with a Volvo or Mann. How many miles on the car? Sometimes an oil change will cause lifter ticking, especially of you don't install the proper filter or don't prime the filter.

 

Add "replace the heater core" if you don't know the history.

 

I ordered some mann filters from IPD and will be switching the filter as soon as it gets here.

I'll also look into the heater core. Thanks for the help
