My '72 911T

A Dowty seal might work as well, if you have enough thread to accommodate the extra width.

That’s what I had on there that leaked, I think the slightly rough surface damaged the O Ring when I did it up. Switched back to aluminium washer for now.

The other detent still has a dowty on it, as does the oil pressure sensor!

Those bolts weep on my Lola mag case box, 1973 vintage out of my 73T

What about the engine sealing Loctite used on the case assembly?
That keeps oil in ok and the joint can be broken with ease.

The alum case 915 Mike has rebuilt some years ago in my 911 is dry everywhere, maybe the mag cases are not oil tight in thin sections?

Would not surprise me.

There are a few loctite recipes that would work. I tend to use 518 for that sort of situation (metal sealing washer). Its anaerobic, tacky, red flange sealer. However I mostly use it because ive got a big tube of it, and other similar products would do equally well. (574 for example)

It works! Lap of Honiston Pass this morning having endured a soaking M6 yesterday:)



Snow and hail just to focus the mind

We have stalkers everywhere!
Remind me not to have an affair in the 911

Temporarily given up trying to fix the tacho so put it (loosely) back together so I can use the car whilst sourcing a replacement.

[Gary71]

I needed to swap an instrument bulb or two so did that then put it back in. This is when it went a bit wrong…

I turned the lights on to check and then there was a fizzing noise and some smoke escaped from the wires!

For reasons unknown one of the bulbs had shorted in its holder and I now know that the instrument light circuit isn’t fused and how much smoke one wire can cause in 20 seconds!

[Gary71]

That bulb holder is now toast along with that wire, and I’ve added a 2amp fuse into the circuit.

Dead easy to do as there is a spade join where the wire separates so a little link harness and bit more tape than in this pic and put it all back with no smoke this time!

Do we get to nick name you Smokey and the Bandit now?

That was rather scary , I bet!

Had a lovely day Saturday afternoon exploring my fave parts of North wales. Car running lovely, just a bit more noise than I’d like from the RHS of the engine, so will look at clearances again.






Fitted a known good rev counter on Sunday as mine has stopped working altogether (stuck at 2k!) and it still wobbles… so I’m guessing something else is going on that eventually killed the original. So I’ll disconnect the new one and have a think!

Hi Gary, I presume that you have checked the distributor points gap? A wobbly tacho reading is usually the first sign that the points have worn.

Not recently, must admit! Will do that
