Original Tbelt @120,000 - Are there warning signs of a break? 850

Greetings:

Just replaced my thermostat and feeling almost cavalier, looking to my next repair on my 96 850 which I've only owned for about 7 months....looking for ideas from the group as to what would be most important to tackle next.

1-I have a very persistent oil leak, which I believe is the rear seal. I don't think this is a great DIY project for a car I need to dry everyday. However, I read so mu about cleaning the oil trap, would this be a good next project?

2-The timing belt is original, are there warning signs before it breaks? Would you change this out now?

Basically, what would you fix next if you sort of had the time, but not the money?

Thanks
Christian

I think Klaus gave some great advice in clearing up some of the issues. My experience on a 2001 V70 obviously didn't apply. If you can do this w/out removing the crank pully, then I'd say that is the way to go. I've heard other say you could do it with my 2001, and perhaps that is possible, but not for a person of my patience level. I tried for a few minutes and then resigned myself to removing the pulley.

It is hard to believe your belt is 120K miles old, most break before then. It is possible that the sticker fell off after it was changed at 70K. Check the Tbelt and look for cracks on both sides of the belt. If there are any, replace it ASAP. Borton will charge about $100 for both belts and 2 hours of labor and will check the rollers to see if they need replacement also.

The oil seperator box requires the removal of the intake manifold and can take 5-6 hours of DIY time, parts from FCPGroton is about $120. The rear cam seal is not that hard to do, about 1 hour DIY, a little more if it is a turbo to get the intercooler pipes out of the way.

Remember, if the Tbelt breaks, you will need a new engine!

I was thinking about the same thing.

Your timing belt, C.A. is good until over 200,000 miles. When your car passes over 200K, I have another medallion for you :)

Take care,
Klaus

Hell Christian,

I would change your timing belt as soon as possible.
I believe they are rated for 70k or 80k miles, however, I have also read that with frequent short-trip service (ie: almost every personal/family car in NA) that interval should be halved to 40k-50k miles. You didn't specify whether your listed mileage is in Kms or Miles, but either way you're due for a timing belt.

I don't believe there would likely be any 'signs' of wear with a timing belt - it will just break and ruin your engine. I suppose you could take the belt cover off and visually inspect the belt....

I am currently gearing up to do this one myself, and I understand it to be a fairly involved job. I wouldn't want to tackle it without a manual and a tool to hold the cams steady while the belt was off (IPD sells one).

I agree with Jadnhm the timing belt should be next. I just did my 01 V70 T5a, and did not need the tool to hold the cam, but you do need to follow the procedure as posted here as this sets up the variable timing issue to minimize movement. Mine did move about a tooth's worth, but you can just grab the sprocket on the cam and put it back. I'd suggest counting the ribs between the cam centering marks BEFORE DISSASSEMBLY to make sure you get that part tensioned (installed) correctly (this will help confirm the cam didn't move). While I didn't need the cam holder, the crank holder is a different matter! The 30mm nut can be easily gotten off with a air impact wrench, but getting the correct torque to put it back is an entirely different issue. Without the hold tool this is difficult to hold the crank to torque setting requirements. I had to improvise by putting 2 grade 8 extra long bolts (10 mm) into the pulley. Just get full thread engagement but do not tighten. You can then wedge a screw driver or tire iron in between and allow that to swing until it jams on the frame to tighten the 30 mm bolt. I don't recommend this because if a bolt breaks, you'll need to be able to get it out. I will make my own spanner type wrench to hold it for my next belt change.

Please realize my comments are for the 2001 model, yours may be different as I have heard a lot of forum members comment on cam movement. Can a more experienced member comment on what models you need the cam tool (if at all). Also comments on holding the crank during reassembly would probably be beneficial to many members.

Good Luck!

I would second the motion to hear from more experienced FWD/AWD brick-ers on their experience with doing timing belt changes. Perhaps we should start a new thread?

Or, read this:

The 1998s don't have VVT, so you don't have to worry about it. Removing the crank pully is also not required, just small fingers.
