I think the flakes might be "SALTS" precipitation, Filter them out with a coffee filter- one possible "solution" (Pun intended!)
I need to purchase some Ph testing strips to keep tabs on my concentration levels and "sweeten" the solution periodically to maintain effectiveness.

Jackpot!  I think you are correct.

Good idea on the Ph.  I wonder what a good "range" would be?

I know he mentioned that using HARD water instead of distilled water can cause surface finish streaking, & maintaining your ph range is critical to the solutions effectiveness.

I've only been using distilled water.

On a somewhat related topic, were there any internal changes to the 302 when they changed from the 6-8 to 6.5-8 tach?  I'm thinking screw in studs and guideplates?  Did the 302 ever have screw in studs and guideplates?  I seem to read differing statements on this.

My used solution get whites "flakes" that tend float around in it.  It still seems to work OK.  Any idea what these are?

Hood hinges and latch catch are manganese phosphate. Bigger darker almost black crystals, must be oiled and is used for applications where parts rub one another.

The black Zinc on bolts is a passivation conversion from silver zinc using a chemical dip.
Same with Yellow, Clear, and Olive. ALL four are Passivation conversions of silver zinc which modify the surface of the ZINC coating into a harder surface more resistant to abrasion and corrosion.

FWIW I have been ZINC plating parts lately and as a sample I have had a fender shim laying in the driveway since January and it has yet to show a spec of rust yet.

First I've heard about the hinges and release mechanism being manganese phosphated.  When I stripped the paint from my originals, they were a lighter grey more like zinc phosphate.  When i zinc'd mine they came out a dead ringer for the original grey.

Are you guys using it mostly on bolts? or what other items are you using it on?
What is the process for using it on bolts that is the most simple?
The big parts on our cars are the hood hinges-springs and the hood release mechanism in front of the rad support.

Other non-fastener items CAN be the Hurst shifter mount plate, the Hurst shifter housing (check first, it varies on when made), shifter-backdrive linkage.

Stuff works great.

Got some white "floaties" in my premixed-reused solution.  Doesn't seem to affect anything as far as performance.  Any concerns?

Hey Bullitt!

No!!! I hate clear it stays in a garage and likes the paint job NATURE gave it! Plus when I take it out everybody asks when RU going to restore or paint it! I would get bored if I didn't have to answer all the same questions! Tks! Bill

It was interesting to me that the 'dykes' rings were not mentioned... (for drag racing purposes)...

Very popular on 2 strokes in the 70's.  Single rings located very close to the top of the piston.

I think burial vaults are to keep things in, not out.

See any zombies roaming around lately?  See, they work! ;D

Yup I could have been clearer but by 'may have what you need' meant a solution to fix the stripped threads, or a correct vent bowl.
Also in re-reading the OP's question I missed that it was particularly the rear bowl - I *think* only front bowls were vented where required, but anyway the recommendation for Eric still stands. He's very knowledgeable and does fantastic work - restored a 4053 for me and it was so perfectly done that I wondered if it deserved to be in an illuminated display cabinet rather than hidden under an air cleaner!
Had Eric do the 4555 on my 70.  The  worst thing is that the air cleaners drop so low you can't see the beautiful work.  Thinking about putting tiny mirrors on the intake to look underneath like at the car shows to look underneath the car!

General Discussion / Re: Reason for the spiral shock design?
« on: April 17, 2018, 03:58:51 PM »
Never took one apart but these were "tube-in-tube" designs meaning there was an inner tube inside the outer tube.  The inner tube needs something to locate in the center of the outer tube and still allow the oil to flow when the shaft moves.  Most shocks have spacers that are welded to the inner tube.  These are extra parts-processes.  My guess is Delco engineers eliminated these part-processes by rolling the "spacer" into the outside tube (shock body) with the grooves.

Most modern shocks a single tube and gas filled. 

Incidentally, Delco shocks were all made in a factory about 5 miles from where I live.  Many neighbors-family worked there when I was growing up.  Long gone now.

"Coffin" or "clamshell" or "flanged" whatever you want to call it power steering pump.  Those weren't on cars until 71.
