It will go away after a properly heat up of the engine. Unlucky if you will replace the lifters- as I did see the post of it- with the audi lifters you must do the job again. But hey you are now heaving lots of experience I dd bet you can do it withon two hours.

Having watched the video with the English translation, I was amazed at all the items that needed to be taken off to do this job. I do not work on my car myself but take it to a mechanic who knows the car. Approximately how many hours would this job take to do?

 

And what parts would you recommend changing as so mush is taken off the car, besides the seals, gaskets and the water pump that were mentioned in the video.

 

Should the water pump be changed on a time interval, even if there are no leaks?

Good questions William, I don't know how many shop hours to do this job, but now that I'm familiar with moving things out of the way in the engine bay to get to other things I could probably replace the timing belt in less than 8 hours over the course of a weekend. (I'm slow and cautious). I'll have the chance to test this next year which will be my 4th season of ownership and my first time replacing the timing belt myself. But I wouldn't be surprised if it were a 2-3 hour job by the book; but you have to include the other things that would be wise to replace at the same time, so maybe 4-5 shop hours (just an inexperienced guess). I have found that for jobs I took to my mechanic (all belts and fluids when I bought the car, then later the clutch & Flywheel) that days to weeks went by waiting for parts and waiting for the mechanic to get back to my car, so with that in mind I can get jobs done faster and cheaper than my mechanic, even though I am slow and cautious.

 

The water pump issue has been debated back and forth, but from what I've read about the WP on this particular car, I would say the conventional wisdom is the old adage "if it aint broke don't fix it" because owners have reported failures of new/rebuilt WPs within a very short time of replacing a working original pump simply as a "While-you're-in-there" (WYIT).

a timing belt job, done right, which includes timing the cams, generally takes about 8 hours soup to nuts

so

 

a timing belt job, done right, which includes timing the cams, generally takes about 8 hours soup to nuts

so when do you recommend changing the water pump, is it based on time or miles?

 

I drive my car about 2000-30000 miles per year, as I drive another 3000-4000 in my minivan or a total of about 5000-7000 per year. in both cars.

tough call.  i've changed mine twice since i've had it.  if the car sits, then it's a good idea to change it, regardless of miles.  if you drive it a lot, then it may be ok for up to 60k miles, as long as it isn't leaking.

I am looking to have variocam pads replaced and timing belt done at the same time.  Any recommendations on the timing belt brand:   Genuine Porsche, Gates, Continental ?

Gates seems to be the consensus best brand. Avoid Continental.

During a recent labor charges "benchmarking" exercise, one of the repair costs sites I ran across had this statement under the 968 timing belt replacement job info :      

" A worn timing belt can result in trouble codes from the camshaft or crankshaft sensors, causing a dashboard warning light to be lit. The engine can make slapping or scraping noises if the timing belt is loose or worn " 

    :blink:   Really ?!   Warning lights and slapping noises when the belts are wearing down ?   Wow, that 's a new revelation re fault codes giving you advance notice of impending doom ..only wish it was true.. or, maybe I must have the basic 968 model which came without that warning lights option.  Dammit, I could have saved $ 6 K in repair bills . :glare:  :whine:

<p style="margin-left:40px;">it only slaps and scraps momentarily just before the your **cked light illuminates, you can get the engine codes once the car is at the indie having a 8k engine rebuild

I have heard chains (specifically Nissan 4 cyl) make a slapping sound as they got loose and started sawing through the block, but if a belt does that I think the sound you hear is your wallet being slapped around by your mechanic. i

Hey guys.  I've had mine for two years, put on only about 4500 miles (66k total).  Yeah, I know, time is important regardless of distance.  The guy before me said the belt had been changed a year before, but he had lost the receipt for the job.  So it's anyone's guess.  Accordingly, I'm going to get the shop to change the belt first thing when it comes out of the garage in the spring.  I guess the water pump should be changed too given the effort and I have no record how old the pump is, right?

 

Given that, I was thinking about getting the following from Zims since I heard they were decent quality.  Can anyone confirm that?

Is there anything else I need besides this timing belt package, water pump, gasket, and block off plate?

 

Thanks for the advice!

Generally, I do not change the water pump with each belt change. The only other thing that seems to be a no brainer is if the balance shaft seals are leaking (if they are not leaking don't touch them, or they will be).

 

JMHO,

I'm a bit sceptical about new water pump for $145. I replaced my original one with a brand new Laso for about $350, but it started to leak after about a year. After replacing it with OEM Porsche the problem was gone. The price of the original one hurts though. One more thing to check - Zims site lists the same pump for 944 and 968 whereas there are differences between the two if I remember correctly.

depending on the year of the 944.

 

our cars have a 78mm impellor so did some of the late 944's Turbo and S2, the early cars had a 68mm impellor

 

current part number is 944 106 021 24 @ £516.00 $658

 

there is a kit available.

 

that comes with...

 

Gasket

Round Seal?

Bolts

Washers

Nuts

Roll pin

Shim

Thermostat

Water Pump

and a few other bits

 

Part Number 944 106 021 AX (AX=Exchange) @  £432.00 = $551

 

that's basically everything in PET image 105-00 except 7,8,9

If you don't know how long the water pump has been on the car, you should change it when doing the timing belt. Gates seems to be the preferred belt brand. I was able to get a factory rebuilt pump through my local Porsche dealer, had to come from Germany, with a core exchange. Took about 4 weeks to get it. Don't recall the price right now but it was quite reasonable, less than aftermarket brands, and my mechanic said it looked new when he installed it. And it was Porsche warranteed.

The 2.5 944 uses a different pump, later ones are ok.


Do not use additional sealant on the gasket. It should make a perfect seal without it.


A decent pump should last long enough to be changed at every second belt change. Decent as in definitely not Chinese.

When I did my belts year before last the water pump was dated 05/1992 no bearing play but a bit noisy at 139k miles
