Chrenan you rebuilt the 924 motor that can't be less difficult than changing a bumch of belts on a 944. Just because there are more belts I think 5 belts in total doesn't really make it harder but more time consuming. haha I'm talking like I know what I'm talking aobut

the main thing is getting the tdc right if you get the balance belt on wrong it won't wreck the motor when you try and crank it....

I guess most people think that I shouldn't do it myself I'll make the decision when I get the car and check it out in real life rather than pics. In pictures with the engine out the timing belt and balance shaft belts don't look too bad.

the things that will give me problems will be removing the big oil pump bolt and pulling out the gear.... Also I heard it's easy to break the water pump bolts and then I'd be screwed. I just have basic wrenches and sockets I'll need a gear puller like that pic, better torque wrench and all the other special tools (120 bucks on ebay).

Honestly I don't get why everyone thinks that looks bad, just becausethere is a balance belt and balanceshafts in front of the timing belt makes it that much harder than any other car?

I think I've changed my mind again about doing the timing belt / water pump myself. I read a lot of posts on Clarks garage and Rennlist and it looks like almost everyone breaks a couple of the water pump studs when removing the water pump and a lot of them have trouble getting the studs out even with a torch and drill, sounds too frustrating.

Also it looks like a good idea to replace the cam belt tensioner stud, a couple of people have had the tensioner stud break off at the block so that should also be replaced and it look like a paint to get off, especially if you break it.

So I change my mind if it was just the belts and rollers I would do it but with the risk of breaking studs and having to take the car to a machine shop to have them removed and fixed it's not really worth the risk. Plus it's stupid to not replace the oil seals.


I guess I'll pay the 2000 or whatever and then I can forget about front end service for a long time.

haha, sorry Stu2j, I don't want to do a butched job removing everything and then breaking a stud in the engine and then buying drills and torches trying to fix it I read a lot of posts and it seems like you're guaranteed to break studs.....

Next timing change is much easier with new studs intalled and you don't have to replace the oil seals every timing change.


I'm getting the car today in a few hours and the guy said he'll bring as many receipts that he can find so maybe I'll have the receipt for at least the belt and rollers and clutch.

Also, does the 944S2/968 motor have the same belt issues? If not, at what stage were they ironed out? (2.7 or 16 valve?)

Well I dropped the tranny and changed the clutch on the 924 myself, but I wouldn't touch the belts on my 944. I'm going to watch the guy do it at the shop and maybe next time...
The 944S2 engine definitely has the same issues as the 2.5litre. Different sources quote different tensions I think (porsche, pasha, chilton etc)...
The 87 and later cars have a built-in timing belt tensioner that means you don't need the p9201 tool, though you are recommended to use it on the other belts.

Car is here now. I'm a little disappointed but not really suprised, the car definately looks like it was in some type of collison recently and thus was repainted at the body shop. I say this because there are other clues in addition to the car being "keyed" and then repainted. The headlights go up and down but they are too noisy I think and when you shut it makes a "clunk" sound don't think they're suppose to be like that, also you can see one of hte headlights raises faster than the other, but maybe this is just a binding headlight thing....

other thing the driver door like my 924 sticks out a tiny bit from the rest of hte body panels, notthing that most people would notice but if You look closely at the side of the car the door is not flush with the rear of the car, the passenger side is a little better.


another thing again, the driver seatbelt needs to be replaced as when you pull on it, it does not lock as it should, passenger side works fine, again seatbelts probably break during a crash. there are other minor clues also, hood is not completely flush on one side but they are all very minor.

What I worry is possible frame damage, but the car drove good during the test drive.

last I think it's called the 'valance' ? it's under the front pumber and it's plastic, on one side it is cracked and has a fiberglass patch on the backside and is a little loose but this isn't part of the body and again you won't really see the crack unless you look under the car.


Ok now the car sounds horrible but it still looks good, the paint looks like a quality paint job and looks very nice. Not sure what wheels I have cookie cutters or Fuchs? I get them confused. Also will eventually need tires they are 2 different brands of tires on and they aren't all season.



I'll post pics tomorrow when it's sunny before I go to work.

Oh and the guy gave me lots of receipts all of them are for parts from Weissach not anything for labour or work done. There is a new radiator, starter, AC components, sunroof seal.

There is a receipt from Dec 22, 2004 (parts) timing belt, balance belt, rollers, water pump. So I guess he replaced it himself around that time, so its getting 2 years old. He says the belts have 10,000 kms on them. I have no idea if they were installed and tensioned properly. Also I don't think the oil seals were replaced. I'm going to take the timing cover off and look at it myself.

Another thing when I put the key in the ignition, the computer shows "check brake pads" and "check brake fluid" but when you start the car it goes off. Also when I start the car when it was still hot it would idle at 600 rpm and then as soon as I step on the gas for 1 sec it would go up to 1100 rpm and stay there weird. Also the oil pressure needle flies up and down between 2-2.5 bar at idle.


Also after the 45 minute drive when the car was shut off for 10 minutes and then I started it again and let it iddle on my driveway the temperature needle was over the mid point not sure if it should run that hot, I heard the fan come one once but it quicly went off again even when the needle was in the high temp area (not red area but halfway past the mid area. I'll have to keep an eye on this just in case.


I"m probably just worrying too much.


What do you guys think? still change the timing belts/ water pump or just get it checked (tension) and try and drive it for a year.
