My 850 started ticking pretty solidly tonight.

I am going to sell the car and get something newer I think.

It most likely won't be a Volvo, unfortunately.

I'm extremely bummed because I was at the point where I was going to be able to fix the boost issue and start doing stuff to it. I REALLY liked this 850. It still drives smooth, but I don't want to chance it.

Most likely will be returning to my Toyota/Lexus roots. I am considering a GS300 or an ES330. Its up in the air right now.

I want to thank all of you, especially Tech, for the info and fun I've had here. I'm sure someday I'll be back here. Most likely with an S60R...mmm.

I'll pop in time to time to see how everyone is doing.

So, good luck to all of you. Enjoy your cars and have fun with them.

 

Man, that sucks...... But you also can't go wrong with Toyotas. Good Luck!

 

Take care man! I recently got rid of my V70, but still stick around the site.

 

Sorry to see you go. Good luck in your search for a new car. You will be back sooner then later because once the Volvo bug bites, it never goes away.

 

Thanks for all your help. I will miss your distinct avitar. Good luck with the next chapter

 

Thanks guys.

The tick increases with the rev of the engine but then goes away.

Its present at idle also.

I would look for another 850, but for what I sell this for I won't be able to.

 

I mean what do you guys think? Keep it and hope it doesn't blow up?

One other issue is there there is a burning smell at idle sometimes. I have NO idea what it is. Timing belt looks okay, serp looks fine.

I don't know.

I DO NOT want to get rid of this car, but I don't want to be stranded and not have a car, because I'm not taking the Celica out in the winter.

Its not a horrible tick, but I'm sure it would only get worse.

I am going to change the oil and throw a bottle of lucas in with it and see if it goes away.

if it does I will change the oil again in a few days with synthetic and see if it comes back.

 

Dude, Keep it and if it Blows, go buy another one and then when that one blows, well you get the picture

 

Ah man, I already forgot all about you. haha. just kidding. I would do a little research before just giving up on it. Do a compression and leak down test. It's probably just the lifters making the ticking noise as that's what it always is. If it eventually goes away then pretty sure it's not a rod. If it is lifters, that shouldn't be too expensive of a fix.

 

I don't have the skill or time to do those kinds of things. I need something that doesn't make noise...lol.


I changed the oil. The tick is there from idle to 2,000RPM and then goes completely away. As soon as you let off the gas, it goes back to ticking.

 

Sounds like a lifter to me. Check with a mechanic and get some idea of what it would take to fix and factor that into whether you decide to sell or keep the car. I might not be too expensive or too difficult to fix. Good Luck. Even if you do sell the 850 we'll let you hang around the forum.

 

My dad seems to think its a lifter too.


Also, what about this weird burning smell.

Sometimes you can smell it through the vents.

Almost like a burnt rubber smell. I cannot pinpoint it!


Help me out!

 

VJZ,

The T-5R I bought had the exact same problem so the guy (thinking the engine was toast) sold it. I was able to talk him down because the clatter was so loud that it was scary. In the back of my mind I knew a little secret and was not scared of what I heard.

I bought the car and took it home. Here is the little secret...Add a quart of ATF (Automatic Transmission Fluid) to the engine oil. Its viscosity is very thin and it contains additives that will break up the stuck lifters. It took about 45 seconds and my engine was running silent. I left it in there for a few days starting the engine now and then and letting it cycle the oil then shuting it off. When done I changed the oil to some cheap stuff, ran it for a day then changed again to Mobile one.

Bottom line - Perfectly quiet engine.

You have stuck lifters, thats what it sounds like to me. This is the same engine I took the the drag strip Saturday.

 

^^ good tip

 

I fixed a tick on my 850 wagon yesterday by adding about a pint of Rislone to the engine oil — same idea as above. My 78 VW Bus has a sticky lifter on one of the cylinders, and the mechanic I bought it from said, "I never go for snake oil, but try adding a quart of Rislone with every oil change and it'll keep that lifter free." My the Bus is running strong at 230k+ so, guess it worked.

 

Really!?!?! Never heard of that before. I want to try that on my wagon, see if that could possibly fix the collapsed lifter I think it has. It would make it a lot easier to work on if I could drive it.

 

Try a heavy duty dose of motor flush then change the oil. It might be nothing more than a sticking lifter. If you can't find motor flush, put about a quart of kerosene in the crankcase, and let the motor run (don't drive, but vary the RPM from idle to about 2500) for about 7-10 minutes. LEt it cool a bit, drain the oil and put in fresh.

 

Mine has had a tick for a about 13,000 miles now. It is annoying and kinda embarrassing, but I know it is not anything major like a rod bearing. Also, mine tends to stop ticking after a long drive on the highway. Maybe I will try the ATF thing and see if it will go away.

 

Yes try the flushing. I have seen cars drive for years with a lifter tick.
