Yes, timing chain as stated earlier. If you car has more than 81K miles you should be looking to replace it or have it replaced. Its quite costly depending on how the mechanic decides to do it. Doing so however will result in trouble free miles, less oil consumption and not running the risk of having your engine seize while driving. Even for the intermediate mechanic its a daunting task. Once projected to be in the hours of 20-22 to complete, alas mine took almost 30 days due to a lot of stubborn bolts and part delays. Its also a great opportunity for either you or your mechanic to access other potential failing parts such as your water pump which in my case was past due and on its way to failure, and also examine your oil pan to determine how your car is handling its oil use and weather or not you have slugging problems.
Given that its a '01, it must be a T7 turbo with the chain; later and earlier models were either an I4 or a V6.this might be stupid but i just bought a 2001 Saab and i would like to know if its a chain or a belt? could anybody help me out?
You replaced the chain with the motor inside the car?
Exactly! This is very unnecessary at 81K miles; some cars with more than double that mileage never needed replacing the chain.But why do this job as a maintenance job at 81 k miles or any other mileage.
I would only do the job if the chain was stretched. The tensioner would need to be at its outer limit and the chain would need to making noise before I would consider replacing the chain and guides.
the chain in our cars, pending any oiling issues should last darn near the life of the motor! I would not even think about it until Im nearing 200k
Please don't make statements like that when you have absolutely nothing to back up your assumptions. The timing chains on our cars last well past the 200K+ miles mark indeed if the engine is maintained properly and the oil changed regularly. The indication was to measure the extension at the 80K mark not to replace!200K miles??...ooof, your assuming too much out of an engine if you think you can go that long without opening her up even half way in between ....especially a Saab.

T7 cars specifically have some sludge issues when the car isn't maintained properly with the PCV version 6 upgrade and proper synthetic oil proper & oil change intervals.
The sludge buildup on the oil pickup screen reduces the oil flow in the engine. The oil starvation causes friction and excessive heat that will stretch the timing chain over time past the allowed limit. When the timing chain is extended past its limits you'll hear the timing chain slapping in there. Your car may have had some sludge in the past that was cleaned but the timing chain may not have been replaced at the time. 80K miles is really nothing on a SAAB timing chain if the proper maintenance is followed.
By the way there was a guy that went past the million miles with a SAAB 900 a few years ago. It had its original engine but the guy maintained it pretty well IIRC it was replaced with a brand new 9-5 courtesy from SAAB and SAAB acquired the old car for the SAAB museum.
Yeah :roll:.......And out of all the Saab's how many cars actually reach that mark, if they all did I doubt Saab would be giving out free 9-5's...lol While Im sure you though that nice explanation on sludging was relevant to I guess show me that you know something about engines, Im not quite sure what facts your exactly looking for to back up my statement? But if I was to use a backup it would be this entire forum...I'm sure all the people here who have replaced a bad timing chain or rebuilt an engine would love to hear that their cars should have gone 200k miles...lol
Simply put, I dont doubt the longevity of Saab engines or I wouldn't have bought one. However I still dont think one opinion should cover every engine. My engine happened to be pristine aside from some left over varnish from the semi synth oil used prior because I switched to AMSOIL at 20k miles....(seen in the photos above in prior posts) my pick up screen had very little debris as well mostly because I have a two stage filter system as well as a filter magnet on the second filter.
Maybe some could consider my timing change un-necessary especially since I am the origination owner and have changed the oil religiously even though I can get around 35K miles per oil change. However , if I bought a Saab second hand with 81k, like evoxkib stated in the first thread. I wouldn't assume anything or leave to chance that the engine was well maintained or serviced regulatory just because my engine "could" go 200k. Because unlike most people on this forum, your average car owner turns the key and drives a car and usually ignores most preventive maintenance unless instructed by a decent mechanic. So as with this case I would at the very least pop off the valve cover and see whats going on inside before I just assume that because the chain is "supposed" to last 200K that I should just keep driving the car unaware of any other existing issues.
There is no one answer for the situation. My answer is investigate and/or change the chain. Agree or dont agree thats up the the reader....thats why they call it a forum.
And after all the stuff we wrote about timing/balance chains, we should have said. Great Car these 93's and the earlier Ng900s - my daughter now has mine!this might be stupid but i just bought a 2001 saab and i would like to know if its a chain or a belt? could anybody help me out?
And the early Chryslers with the 2.6 engines as well as the GM's J serie 2.0 engines :lol:And after all the stuff we wrote about timing/balance chains, we should have said. Great Car these 93's and the earlier Ng900s - my daughter now has mine!
She even drove it for 1-15 mins at 60-70kph with the oil light on!. And no damage to the engine!! But that is another story!!
I would recommend you read up on the sludge issue in the 95 forum. This is the only real issue that Saab have in the later model engines.
Normal maintenance and a sensible approach to caring for the car will eliminate these issues. And we should say other cars of this ear had sludge issues as well.
If you want a horror story about timing chains, check out the early Ford Explorers with the V8 engine!!
Saabs are angels by comparison!!
I agree with hkaysii on this point. The timing chain tensioner was changed in the late 80's and corrected a rather poor design which caused premature timing chain failures. The current design has been in use since ~MY88 and is nigh on bulletproof provided the owner has kept up with oil/filter changes throughout it's lifespan. It's not uncommon for the chains to last 200k+, and if yours went at 80k, then the previous owner did something wrong (or you, if you are the original owner). I'd check the tensioner every 50k or so as part of regular maintenance (tensioner should not exceed 11mm), but to replace it at 80k as part of a regular maintenance schedule is just downright costly and irresponsible.200K miles??...ooof, your assuming too much out of an engine if you think you can go that long without opening her up even half way in between ....especially a Saab.
I think this might have something to do with it. 35k on an oil change is absolutely bonkers for a turbocharged car. Eiron (forum member here) has gone 15-20k on fully synthetic with an NA, but the heat, high pressures and extreme stress that the engine is subjected to with a turbo makes 35k look like suicide.Saabboy93se said:Maybe some could consider my timing change un-necessary especially since I am the origination owner and have changed the oil religiously even though I can get around 35K miles per oil change.
