TR4/4A TR4 Crankcase Vent Pipe Mounting

[Tim Tucker]

Guys,
I'm in the process of mounting my crankcase vent pipe. I pulled the plug (PITA) and have the pipe in the hole. I assumed it attached to one of the oil pan bolts. Perhaps I was wrong. Can anyone help me here?

Here is a picture of what I have:


Here is a picture of the piece I thought I needed to fab to mount it up. Picture was found someone on the internet years ago.


I would like to get this mounted up looking close to original. Any help would be greatly appreciated!

I really need to look at the pictures in my Bently more often...
Figure 1 on 1-106a has it very clearly...sorry..

Good you found it! That part is actually confusing because there were at least two vent pipe variations - one needed the twisty tab you show in the picture, one just needed a straight tab. Just fyi after you fab up a tab, the factory used a thick spacer washer under the tab to mount it to the sump. Just a washer or two and you'll be in good shape.

Good to know there is in fact a "twisty" tab...As it turns out all of my years of keeping metal bits & pieces paid off. I scrounged through the box and found the perfect tab. I drilled out a 5/16" square nut for the spacer and came up with this:

The tab is a bit thicker than original, but it does the job. Many Thanks!
