About a year ago, I drained the oil in my deuce transmission (very dark) and put 40wt in and magnets on the fill and drain plugs. Yesterday, while preparing for a 150 mile trip, I discovered that the fill plug magnet had quite a bit of metal glitter. I drained the oil and found the same amount...

Hey, nobody else provides as much entertainment as you do. Til next time, Rusty.... :-D

Modern tractors still use break in oil. At least the green ones do.

Rusty, please see here, right from the ring manufacturer: http://www.ms-motorservice.com.tr/fileadmin/media/MAM/PDF_Assets/ks_50003958-02_web_53094.pdf 1.6.11Piston ring movementsRing rotationIn order for piston rings to run-in andseal properly, they must be able to rotatefreely in their...

LOL. I know you love to argue EVERYTHING. You are correct that they will stop rotating if the cylinder becomes out of round. Otherwise, they will normally rotate. This has been studied quite a bit by engineers and published; read up. Let me know if you need some hand-holding and I'll even...

Yes, piston rings rotate. I'd guess that the cross hatch is the cause. What is also interesting is that the rings will rotate at different rates. Accordingly, no matter that you carefully you space out the gaps, they will eventually line up.... and then move out of alignment....

You wrote "the Air-Pak has a "multiple" factor of 10 between the inlet and outlet pressures" which is not really what your scanned document states. The document states that you multiply the third part number by 10 to get the hydraulic pressure at an air pressure of 90 psi under full braking...

I don't think that is what it says. Read your scanned text again. You multiply the part number by a factor of 10.

TM 9-1819B (page 192) states that there is a factor of 17x between the applied air pressure and the resulting hydraulic pressure.

I never buyed into this tale. An occasional use of ether would wear the cylinders due to burning off oil but sustained 1200 EGT won't?

I don't see any reason why an LDT couldn't do LDS power levels. However, based on your boost pressure, you are WAY WAY beyond stock LDS power levels: stock LDS boost is 4.9psi at 1600 rpm and 9.9psi at 2400. Your rings may simply be stuck due to the excessive piston temperature forming ring...

The chevy oil flow referenced above is at oil pump speed which is half of the engine speed. In other words, the SBC is spinning at 6k crankshaft rpm.

The field method is described in the LDS troubleshooting manual: boost pressure is 20" Hg (9.8 psi) at 2400 rpm and 10" Hg (4.9 psi) at 1600 rpm. Is the LDT boost specified in any of the manuals?

I went to Honolulu for a conference a few years ago and took the wife. Honolulu has a problem with their sewage. Apparently, they pipe it out to sea but it flows back in to shore (read about it in the paper while we were there). We were both sick during our stay after a trip to the beach...

What heads don't fit? This is another potential supplier: http://www.dieselinjectionengineering.com/products.htm This place has rebuilt PSB heads for $299: http://www.mylexinternational.com/otherservices.htm It also looks like they can rebuild your head/ pump.

I did a quick search on a popular auction site and found one for $391.72 with free shipping.

Do a search for the hydraulic head part number on a popular auction sight.

The LDS manual does say that, if a nut doesn't turn, it should be backed off and retorqued.

I've had FAR better luck with loctite than thread sealant where coolant is involved. Especially on those cases where the hole is a little sloppy and the thread sealant doesn't stay put. Do you think that you can remove the affected studs and loctite them only or will you need to redo the head...
