Ferkels Fantastic Voyage aka 99 miles to the new sty!

[bobm]

I used Casrol syntec in my 78 Fj40 for years with no issues except for $$ cost. 50$ for Earl change in da 70s was spensive. Now I run Castrol 10/30 in all 3 vehicles year round . In temps from - 30° to 98° plus in da Summer

Define right? 100% ethylene glycol in your cooling system isn’t right, for example. Synthetic lubricants are still made from petroleum feedstocks. They are just more controlled in many ways, not the least of which is having the optimal amount of carbon atoms for the task. In other words they are more specific to the task than a wide spectrum of feedstocks, some of which work and some not so much. There’s lots of anecdotal tales about they are too slippery, ect. If you have a leak then you should fix it. I am sure if you don’t want synthetic lubricants that you can find a GL4 non synthetic. No idea about those though as I haven’t used them in years.

Have to agree with the 100% coolant isnt right . But for the synthetic vs conventional gear oil, there are different opinions. I think I am gonna go w/ the FSM reco ,conventional oil. This discussion most always seems to open a can but not necessarily oil.

@Tomba I can happily agree with you… FSM usually is the Holy Grail. The one thing that does stand out in my head….is technology and science. That manual was written say….50 years ago and that was the best available. As everything else has evolved, newer and better options now provide improved service.
The metals didn’t change, camshaft steel, bearings, engine blocks ..all essentially the same. When I was actively rebuilding vintage motorcycle engines….single cylinder, v-twin, 4cyl in-line all 1920, 1930 or 1940 . Some bearings were babbitted and needed hand carving. Especially that 1925 Henderson. I tried synthetic oil with success. For me at the time, synthetic oils were in their infancy and resistance for use was high.

Knew a guy at McGuire AFB who was a helicopter pilot…avid bike guy. Over 50,000 miles a year. Used synthetic oils from the airbase in his bike. When rebuilt…wear was nearly non-existent and that was now almost 30 yrs ago.he had some great rebuild options from those mechanics at the base.

While I was a 30wt zealot 6 decades ago, today I look for the most synthetic crap I can find….they gotta know better than I do.

This post is only to highlight some of the different thinking about modern oil, not to change your mind….but gotta admit there are some changes

Look up 540Ratblog…don’t try reading it… it makes my head explode but some good stuff in there

We could discuss the matter all day long but the fact is, just about any lubricant will work. Where people run into problems is when one or the other runs dry for a decade and a half.
90w130 is a bit thicker and may help to quiet down some of the latent noise.
Thats what Id chose....

Thanks. re running low, I did notice that the transfer case had less than a quart in it. Not sure if it leaked into the trans or leaked out the seal that I am about to replace, I may have a clue when I remove the drum...hoping its the ladder of these 2 potentials.

Question: looks like Lucas 80W-90 gear oil is GL5 rated not GL4 and, their 75WT -90 is GL4 but synthetic. Is there another NON synthetic oil that is recommended for these old x-fer and trans. cases that's GL4 or is the 80W-90 GL5 ok to use?

I like this...

Is the transmission over-filled?

Before the successful 2 man operation to stab it together , the one man option resulted in the trans falling off the trans jack and spilling out the oil in the driveway, so I'm unsure...

Synthetic in new vehicles you’re gonna run lots of stressful miles, you’re wasting your money in a weekend project vehicle. Decent GL-4 and forget it …

yep. the big blue truck with the goods scheduled to arrive on Monday

Ghetto attempt at yellow zincing a few parts before finishing up. This is after several attempts. watched a bunch of videos too but still came out looking like garbage.

 

[knuckle47]

I’ve always wanted to try this… would you guess why this turned out like this?

There are a lot of elements to consider. many of videos I wathced do no use any heat to warm the different solutions. one of the attempts was to heat the degreaser a bit, that didnt solve anything. I have no idea really. I must have tried this 10+ different times. They all turned out like complete effing garbage. starting with creating the zinc solution then trying different timing etc. A complete waste of my time.

I’ve seen pics of this but never tried it, like many things I’m sure it’s a bit of an art.

yeah the crux of the issue is not easy to identify. Must take hours and hours to figure it out or have someone who has done it show you. The videos dont help for s&^%

@Tomba I feel for you … in the last 60 years that I have been an active “tinkerer” I have had a few things I had worked on or with, that ultimately were a waste of time. As I look back, out of maybe 20 really stupid attempts at something….only 5 had absolutely nothing I had learned from it….So, maybe not a complete waste…. But, time will tell. One day, you’ll be ready to do SOMETHING and, you’ll remember doing this zinc project and a monumental twist will actually bring you that success from this s#!t experience
I know its optimistic

I agree. Although right now I'm not sure what I learned from this one. Am sure there may be a lesson and time will tell what that might be. The good news is I can continue with my regular scheduled project that's been SLOWLY moving fwd. This zinc sub project was a hold up but I guess I'm ok with having zebra striped yellow zinc parts here and there.

2 steps forward one back. Filled the t-case and trans w oil . Flushed the block, radiator and heater core . Noticed I left what I thought was the drain cock screw open, perfect for what I was doing . I was gonna filler up w coolant /water. I shoulda looked closer before attampting to tighten that 19mm bolt . There is a screw that plugs the drain sitting in the box where I left it. Oops. The local radiator shop recently closed too.
