Absolutely gorgeous! Well done sir. Well done.
The short block was torn down, cleaned and inspected. It was representative of the previous owners claim of being a low mileage example. Everything was quite fresh, minimal wear and is now slowly coming back together.
Also, all of the missing valve train pieces were sourced which will allow continued progress on the top end as well.
The Phoenix has come full circle as of this past weekend. On a journey east our 500SEC returned to the birth place of this project, Phoenix Arizona.
Starfest 2012, sponsored by Mercedes Benz Club of America and Mercedes Benz USA, took place at the beautiful Biltmore Resort in Phoenix. The first ever of it's kind at this prestigious local, allowing vehicles into and onto the main Biltmore courtyard.
Starfest 2012 attracted a wonderful variety of Mercedes Benz from the celebrated Gullwing to it's modern AMG SLS cousin. The vehicles and the venue made for a spectacular day under the scorching Arizona sun.
There was some time to spare prior to the event and a visit to some of Phoenix's finest self service auto dismantlers was in order. One of these pick your bits included the Ecology yard from which this project all started. Today the yard deals primary in domestic vehicles but there were a handful of low turn-over, left-over, european examples. No wide bodies but it was a treat to visit this project's birth place, the filthy lot from which this all started.
The W126 designation was well represented at Starfest 2012 and was honored with five of the top honors. One event at a time, the W126 regains the recognition as one of the finest Mercedes ever assembled.
Classic W126 tuners (AMG and Lorinser) were amongst the "modified" group making up a "full house" that was represented by three coupes and two sedans. The grounds were littered with wonderful stock examples as well, a pair of 500E's, three W126's, a handful of R107's, the W123 and the largest single designation, the R129.
After the tour of the grave yards, the attention was refocused on the event. A little wash, wax, sprits, spit and the coupe was ready to make it's way onto the field. Phoenix and Scottsdale are wonderful cities. The trip overall was fantastic and icing on the cake was when our coupe received the honor of 1st in Class.
The entire engine is being sorted, short block included.
I'll be sure to post photos as they become available.
Meanwhile there is a more detailed thread dedicated to the engine portion here:http://www.mercedes-amg-classic.com/....php?f=20&t=11
At first glance, registration for our website may appear lengthy but you need only to provide minimum particulars. Hope you enjoy!
During the past year, since taking possession of the AMG DOHC 4V heads and engine, I have spent a considerable amount of time on research.
This particular example was pulled and disassembled over a decade ago. At the time, the heads were sent out for machining but were never completed and many of the valve train bits went missing.
Assuming that the DOHC 4V heads would check out to be sound, I continued to search far and wide for the missing bits and additional reference materials. One gentleman in Germany reached out and provided me with samples and reference materials for each of the missing bits, which could be used to reproduce the bits if needed. I chose to hold out, as I was still confident that the originals could be located that of which included intake and exhaust valves, valve springs, cups and retainers.
There was one potential resource that I had overlooked here, stateside, Mr. Hartmut Feyhl at Renntech. For those not familiar, he was the lead tech/engineer at AMG North America prior to AMG merging with Mercedes Benz and was responsible for all of the authorized DOHC 4V installations in the U.S. during that time. He later formed Renntech and completed a number of AMG DOHC installation there and continues to produce and engineer products for contemporary Mercedes Benz models today.
As a pleasant surprise, not only did he provide the missing pieces, but Mr. Fehyl also took the time to share his invaluable experience with the DOHC engines. The bits arrived last month and work could begin on the heads and block.
The AMG 4V was now back on track…
Everything was sent off to Motor Works near San Diego, CA, where Sergio Bartolino, who had work with these back in the day, began taking inventory, disassembling, cleaning and inspecting. The short block was stripped and proved to be reflective of the low mileage claimed by the previous owner. There was some scoring in one of the cylinders, but everything else in/on the short block passed inspection.
One of the valve seats was suspect and was replaced. Also, the valve guides installed previously were not only incorrect but not properly installed, thus they were removed and replaced.
More progress to follow...
