Risky Business:  GuysWithRides Purchased This 1985 Porsche 928S As 2020’s Winter Project, sight unseen, for $4,000!

When Rudy’s friend Glenn reached out about selling his 1985 Porsche 928S taking up space in his garage, Rudy jumped at the chance to take over this project car not started in two years.  Follow Rudy on this blog as he attempts to bring this RAD Era supercar back to its former glory and ready in time to drive to the Porsche Club of America’s Fifth Annual Werks Reunion Scheduled for March 5th, 2021 at Amelia Island, Florida.  You can follow Rudy’s Blog below or better yet, subscribe to the GuysWithRides YouTube Channel to be notified every time he posts a new video:

February 4, 2022 Update – Coming soon is the complete video detailing the engine motor mount replacement, but for now, this quick video gives you perspective on the nearly one-inch heigh difference installing new mounts made.

November 27, 2021 Update – This is not how we ever want to leave our local Cars & Coffee:


February 25, 2021 Update – Cold and often snowy weather hampered our efforts to work comfortably in bright enough light needed to troubleshoot a nagging fuel pump ground issue. A clear, sunny, late February day allowed Rudy and Nick to finally resolve the issue and provided a chance to complete a well-overdue 30-mile ride. Here’s a teaser video of what the car sounds like:

January 23rd, 2021 Update – Two new fuel pumps (the first one went bad from stale gas), fuel filters, a clogged tank strainer, and one bad sending unit later, the ground wire leading from the 928’s tank-mounted fuel pump to behind the tail light is bad and continues to cause stalling. We’re just glad it’s not something going on behind the electrical panel.

January 8th, 2021 Update – While Rudy and Nick were finally able to start and idle the 928 after a successful timing belt replacement and full service, old smelly fuel and a deteriorated gas tank-to-fuel-pump hampered their efforts by yet another week as they wait for the latest unexpected part to arrive.  In this video, Rudy walks you through what it takes to troubleshoot and replace a Porsche 928 fuel pump and filter:

January 4th, 2021 Update – IT’S ALIVE! After trying to resuscitate our Porsche 928 following the timing belt and Porken tensioner combined with a full tune-up, Nick and Rudy discovered a faulty fuel pump needed replacement, delaying the startup one more week.  With the replacement pump in place, the 928 fired up! Rudy is slowly working through what is the remnants of some very bad gas.  Stay tuned for a more detailed video later this week.

December 30th, 2020 Update – In this video, Rudy documents in detail the successful installation of the aftermarket Porken Timing Belt tensioner.  With the replacement timing belt now installed, work can finally move forward bringing our 928 back to life…we hope!

December 24th, 2020 – It’s a Christmas Miracle! The Porken Tensioner we’ve been waiting for since December 8th FINALLY arrived on Christmas Eve, so with any luck, we’ll have this car running by New Years!

December 20th, 2020 – In this long-overdue update, Rudy takes you through the problems of trying to rebuild the factory timing belt tensioner as well as the aftermarket upgrade he decided to replace it with.  The only problem now is waiting for the Porken Tensioner to arrive from the Post Office!

November 23rd, 2020 – Unfortunately, one of the eight additional parts needed to complete the major service ordered last week, a $4.50 oil pump shaft seal did not arrive by Monday morning.  Consequently, Rudy used the time to deep clean the parts removed from the 928 that facilitate access to the timing belt and water pump.  In this installment, he provides examples of when its best to use steam versus a parts washer tank:

November 21st, 2020 – Rudy took advantage of a rare hazardous waste disposal day in his town to remove the 928’s stale gas as well as the coolant removed several days prior:

November 20th, 2020 – With complete access completed two days earlier, Nick and Rudy continued on the major service by first removing the harmonic balancer, the hydraulic tensioner, and the water pump tucked behind the timing belt loop:

November 18th, 2020 – With the help of Nick, Rudy takes you through all of the parts that need to be removed in order to gain access to the water pump and timing belt of the 32 Valve, 5.0 Liter V8 found in our “Risky Business” project:

November 1oth, 2020 With the requisite major service parts now in hand, Rudy sets out to start working digging into the front end of the 928 by removing the cooling fan assembly and both distributor caps. Yes, there are two on the 928S 32 valve engine!

November 5th, 2020 – FedEx delivered the balance of the timing belt service kit ordered from 928 Specialists.  Even better, the Eaby purveyor of the $600 928 Service Manuals guided Rudy through where the 32-valve specific information lies in the eight-set volume of dark red three-ring binders.  With nearly $4,000 in parts now in his possession for his $4,000 Porsche, Rudy can finally move forward with the engine’s full maintenance service:

November 4th, 2020:  This past week was a “One Step Forward, Two Steps Back” in the project timeline as Rudy continues to wait for 928 Specialists to send the timing belt and other key parts needed to start the project.  In the interim, Rudy shows how he steam cleans an engine using no solvents or paper towels:

October 28th, 2020: Rudy provides his Week 2 Recap of what he worked on while waiting for the critical timing belt, water pump, and associated parts to arrive:

October 27th, 2020: In the video, Rudy shows how to replace hatch and hood struts on a typical Porsche and most cars:

The first seven days after bringing home our 1985 Porsche 928S from Buffalo was all about sourcing and ordering parts. While Super Cars may get cheap over time, the parts needed to bring them back to like-new condition don’t!

October 14th, 2020: We Shuffle off To Buffalo to Pickup the Car

Rudy provides a quick summary of his and Nick’s road trip from Central New Jersey to Buffalo to pick up “Risky Business”, our 1985 Porsche 928S project car. With only 142 days until the Amelia Island Werks Reunion, Rudy starts the process by testing all of the electrical systems to confirm what works and what needs attention.
