Glycol mains are fine, never had an issue with them. Much less abuse than a rod bearing

A couple of comments - Millenium does great work, nikasil is a lot harder than alusil. You have to have pistons in hand to get coating / machine work done.
Mahle makes a great piston- extremely consistent and exactly to spec.
Now the bad side - custom Mahle pistons will take 6 months to get.

Well, good news: Taking the block to Bearing Services in Portland tomorrow. Ran into a wrench from Grand Prix (911r on BAT), and he referred me - they seem to know what they're talking about, and are willing to take on the work immediately!

Head and flywheel are going to a local shop next week.

I've been keeping busy with a few interior things (weather stripping, door cards, aiieee...). If anyone has suggestions for repairing those damn window guide spot welds I'm all ears! Rebuilt the steering rack (and hopefully didn't make it worse - the rack was pretty leak-free, I'm not sure why I bothered...other than it was on my bench).


Now, for brain trust questions: I've let the lifters (oh boy) sit in clean oil over a few days. Most of em kinda seeped out old oil, but they don't really respond to being pressed on, with a single exception. As far as I can tell, that's not a great sign - I'm gonna throw em in an ultrasonic bath and hope I can break the pistons free and flush out all the gunk, but I'm not super optimistic. Will *probably* be keeping an eye out for a nice set...


On another note: any recommendations for AN fittings?

Aeroquip or Russel or Canton

Don’t by the cheap Chinese garbage such as Jegs brand.

Pegasus caries the good stuff as a vendor

I used Earl's Performance AN fittings when I installed a remote Canton-Mecca oil filter on my highly modified 1976 Capri II many years ago. At the time, the Earl's hoses were easier to cut and assemble (still a PITA though).

For the lifters, you might try this with regular oil and some engine flush (Sea Foam, Aimsoil flush etc)....

^^ we did just that when doing the heads on a friend's C6 Z06 engine, as this friend also has a 951 and remembered that trick of yours. The engine ran like a sewing machine when we started it.

Agree with Earls too as I have them also. That was the brand name that was evading my brain this morning.

Well, my wallet isn't too happy but...brand name it is, then! Thanks guys.

Picked up some of the fittings I need from Russel, not least because I kinda like their black/silver colorscheme...

Block and such are off at Bearing Services, we'll see what they say in the coming week or so. One thing of note..the foreman suggested, apropos of nothing really, that I go with oversized rod bearings. I know the cranks are allegedly pretty hard, and don't really wear much (I don't have calipers in that range, so I haven't actually checked). Is there any wisdom in preemptively going that route? Looks like a set of ACLs is still $80ish, so not exactly a huge loss...

Edit: will be giving the vacuum trick a whirl this evening, assuming I can track down my vacuum pump!

BTW - the non stainless hose is the way to go unless you are right by something really hot. The 'classic' braided stainless steel hose might as well be a hacksaw blade if you let it contact anything. a little vibration and it will chew through aluminum very fast and steel too, just a little slower!
Also - read up on how to torque the connections - many a good fitting/ hose has been ruined by cranking them too tight,
