Really nice - I wish my engine builder took note in terms of pics and updates; it appeared to
Be a chore to him to let his customer know what was going on...

I’ve not seen those pistons before, nice option

Sure do enjoy Steven's tools.:cool:

Just curious... I don't see any locking tabs on the oil pump nuts? :confused:

I was looking into doing twin plug on my 3.2, but realized the costs get rather high. Getting the heads drilled for a 2nd plug is cheap compared to finding a distributor and ECM and ignition setup to handle the added spark.


I decided to stay single plug with the same 3.4 Mahle Max Moritz design 9.8 compression P&C (my 3.2 pistons had valve slap on them and were alusil).

But also going with 964 cams, Aasco springs and retainters for higher redline.


BTW... REALLY love these pics. I wish someone would just create a video of EVERYTHING they do to build the engine.

There is Trakrat
https://m.youtube.com/watch?v=HqTJ2lgVEKY, if the link doesn’t work search “The Canary Files” this guys documented his entire engine rebuild on YouTube
I’ll be doing the same when I rebuild my 964 engine later this year when I finally get my garage built

Trackrat - The legendary Carroll Smith believed locking tabs don't work. He suggested "prevailing torque" nuts. I suspect nylocs, though less positive, would do.

I'd have to look at the other case half to be sure, but maybe the nut couldn't come all the way off anyway when the case is together? Only the upper nut is subject to tension with the pump turning. The force would vary with RPM, which is a minus for the nut staying put, but maybe not really enough to loosen a properly torqued regular nut?

One doesn't hear about these nuts coming loose, though.

Probably used wave washers and locktite

What do you think Smith thinks about the ability of a wave washer to add anything significant to the stretch of a fastener? To be sure, Porsche used them in some applications, like under all those nuts holding the cam carrier onto the heads.

Loctite maybe, though if Smith is right about the tabs, with the standard torque for an 8mm stud, maybe any flat washer is fine with a standard nut. The washer keeps the nut from gouging the aluminum of the pump.

Cross threading....
 

"Cross threading is almost as good as Locktight"
Anon

I like to tighten it until it strips, then back it off a quarter turn

Amazing thread ..... :eek::eek::eek::eek::eek:

Well done! Great photographic detail.

what size/part number are those Bosch spark plugs you're using there sir

Nuts in that picture of the oil pump installed are actually nyloc style like those used on the valve covers. Like Walt said, the "top-lock" prevailing torque nuts are a better choice here. Nyloc don't provide a lot of locking effect

Interesting choice to use nylocks inside the motor. Porsche never did that, and there are mechanics that recommend against it. Loctite would probably do the trick. How can locking tabs fail anyway?
