I am a new owner of a 1984 - 928S. My first Porsche. The odometer stopped at 122,000 and the guy I bought the car from said it had about 140,000 miles. At my first local PCA meeting they told me that I needed to change my timing belt (about every 70,000 miles) and while I was doing that maybe my water pump at the same time. One guy said it should cost around $1600.00.
The Porsche dealer told me $4800.00 and I am in sticker shock. I am looking for advise, What should it cost and if $4800.00 is correct, how hard is this to do my self?

first off ILL give you the link to the maintenance page.

It is not a job for the light at heart.

There is more then one style of engine so put your car year and model in your signature so that people can tell what type of car you have.

I vote for you to do it yourself! The belt will run you about a $100. The water pump, about $300. Some recommend changing the belt tensioner when doing the work. I probably would with the later 32V engine, but I don't do it as regular maintenance on my '84. 16 valves = non interference. Other than that, you will need a flywheel lock and the Jay Kempf tension tool. Consider both of which an investment. You'll need them again. I also advise following all of the procedures outlined in the WSM when performing the work.

we will walk you through it step by step but you will need and should have a good tool box full of tools to own this type of car. it is way to expensive to pay someone to do it.

$1,600 is certainly in the ballpark given no other surprises (stuff breaking when they dissassemble, etc) and if the tensioner, rollers are in good shape. I just bought an '87 and had quotes all over the map, but ended up below the above number because the water pump wasn't replaced (it was relatively new/low miles on it) and the previous owner replaced tensioners, rollers 25,000 miles ago (had to replace the belt due to age, not necessarily because of high miles/use).
Not sure if I would tackle the job myself, but if I did, I know there are a great deal of knowledgeable and helpful people on this forum.

Yep, please do it yourself and don't pay someone else to learn on YOUR car!:rolleyes:

Also about 50,000 is the most i would push one, it is rare to see one make 70,000 w/o something breaking and causing more damage and requiring a tow. :eek:


Actualy you don't need that many tools to do an '84 it is a lot simpler than a 32 valve.

Where do you live? We may have other 928 OC members in your area that may wnat to lend a hand or even just guide you and may even have some of the special tools.

The belt sells for $28. bucks from one of the Big Three 928 vendors, and also rebuilding the Tensioner is cheep, replace all rhe rollers and guides.

I would highly recomend replacing an much as you can afford While You Are in There (WYAIT). It is cheeper as most is the labor getting it apart.

I have done several in the past few years and it is not hard to do, just take your time and follow the directions from others who have been there.


Oh, and $1,600 is about right for a non-dealer shop work, don't go the dealer route.

Yes but his will most likely look like this.. this s an 85 Euro that had a WP failure and the belt broke and bent a few valves.
