So while I was waiting for various tins to dry , I decided to do a mock-up of the new injectors in the the restored manifolds so see what kind of hose adjustments do I need to make. Now I originally had everything assembled and then tried to place the injectors into the manifold as…

Murbella – Day 39 – New Throttle Body Seals
The Harwal oil seals arrived the other day so I test fit them into the throttle body. These are the same seals that the guy on The Samba used on his bus throttle body. Now they aren’t perfect fits as they are not a 1:1 replacement part. However, I think they’ll do at keeping the…

Murbella – Day 36 – TPS Sensor Case “Repair”
So I pulled out Murbella’s original throttle position sensor (TPS) to compare the one I removed, from the questionable functioning part I purchased. Now I wasn’t concerned in that TPS sensor working so much as I was in the condition of the plastic cover. This “repair” will perfect. The new old part is solid with…

Murbella – Day 34 – The throttle shaft seals
So I pulled the throttle shafts off of the other throttle bodies I have and sure enough, the seals are just as bad and I would not want to reuse them. The VW part number is 022 133 089 A and of course, that’s not something available anymore. Hell, given how many Beetles were sold…

Other People’s Parts – More Used FI components
My order of used FI parts from Bugcity.com arrived today. The throttle body with TPS of unknown status is generally clean, and then plastic on the TPS is perfect, so I can use the cover portion to replace the damaged one I removed from Murbella. I know have 2 backup throttle bodies and linkages and…

Murbella – Day 32 – My injectors arrived back!
I am rather out of words and what my cleaned and restored fuel injectors look like. Remember these pics from a few weeks back? The package I just opened is like magic happened. Other than some wear on the plastic electronic areas, the injectors look practically brand new! And that Cold Start Valve…

Murbella – Day 28 – Fuel Injector Test Results
So I got the Fuel Injector test results back from Cruzin Performance and I’m happy to say that they all passed with flying colors, including the Cold Start Valve! I was a littler worried since I have no idea what to expect given their age and potential, though unlikely, to have 237K miles on them….

Murbella – Day 26 – Finishing the first pass on the plenum and throttle body.
I started working on the 3/4 side of the plenum’s air intake, and went about doing the slow job of disassembling the throttle body. I’ve reached about the end of what I can do with scotch pads, sand paper, a pick, and solvent in terms of cleaning up the aluminum. I just can’t get…

Reference: FI Engine – FI Cylinder Heads
Every day digging through my late model Beetle introduces me to something new and different from most prior years. The tear down of the FI Cylinder Heads for rebuild has introduced me to even more new things. The years 1975-1979 saw the US import models shift from the early 70’s carbureted system to the successor…

Murbella – Day 22 – Throttle Body/Plenum Removed
It took a bit for me to figure out how the plenum and throttle body assembly would come off. Now 1/2 of it rests on where the traditional generator stand would be. And while the 2 front nuts came off, the 1 exposed rear one (near cylinder side) would loosen but not come off. I…
