Call Roger at 928sRUS, he will fix you right up with materials and then print out the instructions found here using search and have at it.
+928. It isn't that bad a job. Just do it like Doc says.

I agree. How long since the coolant has been changed? That stuff turned into an acidic bath in about 1987.

BTW...I can do a timing belt/water pump on a clean engine without any problems in about 5 hours.

I plan on the "normal" job taking 12 hours....and we very seldom "meet" that time...it usually takes longer. Cleaning the area, dealing with frozen hardware, rebuilding the tensioner, getting the "stuck" damper off, dealing with almost every early engine pulling the upper alternator mounting bolt threads, flushing the block, changing the oil pump seals (minimum), all suck up many extra hours.

I would be surprised if his 'book' lists 19 hours. I suspect that, based upon his experience, he may have a good idea of other work that will be necessary and has quoted book time for the belt, pump, and the other items he suspects.

It can take 19 hours to do a proper job on a not-perfect, not-clean 928. It can also be quick if the car is clean, nothing breaks, and nothing other than the belt, pump and tensioner need to be touched. That is however very, very rare.

Thanks Jim. I appreciate the offer. I plan to give my guy a shot at it and go from there. Plus, I have quite a few things to do while it is on the lift. Tranny fluid, differential fluid. Clutch adjustment check, etc. Radiator fluid leak. A whole long list of issues.

I am sure I will need plenty of advice going forward, so, again, thanks for your offer and advice.

The only thing that stopped my pace was the tensioner on the '84 was "upgraded" from the previous shop, and therefore the boot I had from a 'kit' didn't fit... Had to reorder and send back for the correct one. Just ask Dave and Jeanine.

I make a slick adaptor that attaches to the early tensioners, so that they will accept the later boots.

Available from 928 International.

I would plan to be ready for WYAIT situation.
Front main seal, PS and oil pump R/R. Fuel Lines etc as others have said.
I"m sure with enough notice. Jim (Jadz , Myself) can all pitch in. I will have some time the middle of February if that's not too long.

Let me know

Steve was at my garage on Sunday. He noticed I'm pretty well booked thru Feb.
Plus, he already said he's got a shop he's going to try.

This will be interesting..."Tranny fluid, differential fluid. Clutch adjustment check, etc. Radiator fluid leak. A whole long list of issues......." The trans and diff are one unit and share the same lube on 5 speed cars , there is little to adjust on the clutch , coolant leak can be any number of things. As far as the long list goes this could turn into quite a project. Is this the shop that quoted $3,000 ?? as a start !!

I wish you had a list of all the neat stuff you make Greg, my guess is you would sell a lot more stuff if folks knew you made it.

Glad you hooked up with Jim. I was going to ask if you were closer to him and the Richmond crew or up here in NoVa. Hope Jim gave you a good list to get started on. If I stay focused I can to a tbelt job on my car in six hours - mainly because I know exactly what I'm running into. All the sketchy bolts, WYAIT items, etc, were addressed some time ago.

Heck if you schedule far enough out I may be able to head down there and help. Or at least have a beer or three and watch.

This is very good advice.

This guy was well underway before we met him yesterday. Appears he's been lurking here and reading. Pretty well tuned in.

I just wish him well with his mech. Would be good to know a local mech for punt jobs. My guy blew out of town a while ago headed toward Maryland.
