Does anyone know what size bolts I need to mount the rear bumper brackets up into the holes in the frame (there are captive nuts there)
I took my old bolts to the hardware store but I couldn't find a good fit using the thread gauges they had in the store. |
I see by your signature that you may have a 1977 VW transporter.
I notice in a response that the diagram for a rear bumper appears to be a 'blade' bumper, perhaps for a year prior to 1973 (1972??)
Question: are the bolts the same size for years 1972 - 1979?
Thanks

|

I read in Ratwell.com the following:
1.1 Compression Testing:
You've bought a compression tester but it doesn't contain any instructions. Here's what to do:
if you have hydraulic lifters, run the engine the night before for 30 minutes to make sure they are pumped up.
adjust valves if it's near adjustment time
break torque on the plugs with a cold engine so you aren't removing them when the threads in the head are softer from the heat. Just keep them snug.
run the engine for 5 minutes to warm it up
remove all four spark plugs
key off to disable coil and injectors
unplug double relay if you have FI (left plug is mandatory)
What is the rationale for this statement " unplug double relay if you have FI (left plug is mandatory) "
Thank you.

You want to disable the FI and the ignition. Removing both the green and white wires from the #1 terminal on the coil will accomplish this. |

Ratwell says unplug the DR because that will also disable the CSV and the fuel pump. No need to be filling your engine with gas while testing.
And yes, rear bumper bracket to frame bolts are the same from 68-79. _________________ Rust NEVER sleeps and stock never goes out of style.

With a hot engine the CSV shouldn't be doing anything, and having the fuel pump running should matter little. Pull the wire to the double relay and the backup lights off the coil if the FP is a concern to you. You could instead pull only the 12+ wire from the coil but need to be sure it doesn't ground out to anything. I don't like pulling the plug from the double relay as you only get so many shots at doing so before the pins push out of the connector. |

It is #11.
Everything on the PB Warning socket is unplugged.
I'll get out and test the other stuff Sunday.

My stupid question du jour...
How does a fuel injected engine compensate for high altitudes?
I had problems starting and running my '76 Riviera with FI when we were above 5k feet or so. When I got home, she drove normally. So my assumption is the altitude and thin air may have caused the problem. _________________ -Kent-

L-jet isn't that smart, some buses and bugs sold in high states had an altitude switch in the engine compartment and a special ECU, whether that saw an option or te dealers just ordered it like that has never been resolved.
You could re tweak the cogwheel in an AFM and swap it in as a preset unit when climbing in elevation, there's little other things that come to mind to lean the system safely over it's full temperature range.
Edit: A little reading on the option: https://www.thesamba.com/vw/forum/viewtopic.php?t=411925&highlight=altitude+ecu
There's more somewhere but I can't locate it right now. _________________ Rust NEVER sleeps and stock never goes out of style.

Welcome,
This switch sounds interesting, could be something that alters the resistance of temp sensor 2. Pictures would be very helpful here, of the switch, where the wires from it go and the throttle body as well. |
Thanks for the reply! The 1st pic shows the switch mounted just above the CU connector. The 2nd image shows how the leads join into the main wire harness that leads to the double relay mounted on the upper part of the left firewall. 3 wires branch off about mid engine and disappear under the air distribution box and I can wiggle them by grabbing a lead on the Temp Sensor II near Cylinder 3. It's all black magic!

Thanks for the answer, busdaddy. And I think I understand better what was happening while driving at 5-7k feet...
She was running rich to begin with, while at low elevations. So when I was climbing, the mixture kept getting richer as the air thinned. The ultra rich mixture explains why she would suddenly jerk and die at the highest elevations, and also explains why she wouldn't start until after sitting for at least an hour to cool down.
A couple months ago when I took her in for the smog test, she passed pretty easily. But for some reason, (TS2? Dual relay?) she started running rich occasionally. My guess is I need to replace the TS2. Or I'm going to take TCash's previous advice and add the potentiometer. I haven't decided yet. It may be a combination of both, with a switch to override the TS2 if I want. _________________ -Kent-

If you are spending much time at those altitudes you can bump the timing up a bit to help compensate. The general rule is 1° of extra advance for every 1000' above 4000'. |

I wish I had known that. That solution didn't even occur to me (not that I would have EVER thought about it). It would have saved hiring a Uhaul truck and car hauler to get from Utah back to Calif.

Could be, its Brazilian, they made that body style there well into the 70's.
Some really rough looking repairs on the frame, be careful, could be lots of demons hiding beneath turd polish. _________________ Rust NEVER sleeps and stock never goes out of style.

Huh. Did not know that! I'm not buying, just thought I'd do the seller a favor if he had it wrong. Busdaddy, you unknowingly helped me today with an old post in the bay forum re: "turn signal switch", also "cab door locks". Both are working PERFECTLY now thanks to your input! I owe you! |

Hello, my first post on this forum
Where can I get hold of a black old-school lace-up steering wheel cover for my 73' Westie. Something of a decent quality that fits neatly on the original steering wheel.
Thank you! |

Does anyone have a photo of the warning label that is on the center of the dash from a 77 Westy?
I see WW has them, but am trying to see how "accurate" they are - as the Delta Six labels are pretty off.
Also, my original dash was pretty chewed up. I scored one on a trade for some wheels and tires but the holes that were there for switches were in a bit of a different order.
Without my having to dril more holes is it totally weird that I'm planning to put my rear dog, rear defroster, and gas heater switches to the right side of the dash? Other than the order of the holes the padded part is in great shape. _________________ Mike

Putting a dog's butt on the dash officially qualifies as weird, yes. _________________ -Kent-
