Packard Forum Index » V-8 (1955-56)

I've only had a few oil changes on my 56 Patrician, but the first few I used 10w-30 and had loud consistant lifter clatter, with the addition of bardhals istead o lead (recoomended to me on this forum and probably spelled incorrectly) lowered my lifter noise. However since then I've used strait 30 with Lucas oil stabilizer and the instead o lead and the only lifter noise I get is on hills.

I have not dropped my oil pan since I've owned the car, but I'm sure my oil flow problem is due to not cleaning or replacing the oil strainer.

<p>I'm sure it is not. Lifter clatter is due to low oil pressure which is due to a worn out oil pump. The only 100% sure solution is to replace the Packard pump with an Olds 455 oil pump using the adapter kit developed by Eric (Turbopackman), Keith (PackardV8), Kevin (KevinAZ) and myself. This kit can now be obtained from Jack Vines, who has taken over production.</p><p>Craig</p>

Hello Everyone,
It's been awhile since I've posted to this NG, but I still lurk from time to time. Working 50+ hours per week nowdays, I don't get much time for anything.

I have used Mobil 1, 15W50 now for about ten years and 80,000 miles in one 352 engine, and six years and 40,000 in another 352 (both engines in 1956 Stude Golden Hawks). I also change the oil and filter every 10,000 miles.

When I pulled the oil pan on the first car to install a Melling oil pump after around 75,000 miles, I removed the main-caps and checked to see how the MBs were wearing. They all looked like they had maybe 5,000 miles on them. Just about every Packard V8 I have torn down (maybe a dozen) had the lower center main worn into the bronze, and similar wear on #2 and 4.

I am convinced the oil zinc hype is not an issue, at least on my cars.

Oh, by the way, I LOVE the Melling pump!!!

For those that have access to the February 2010 Studebaker Drivers Club magazine Turning Wheels, there is an interesting picture and comment in the Co-Operator section about lack of enough ZDDP in the oil used in a brand new Ford 429/460 rebuild. The cam and flat bottom lifter shown have some severe damage and claim is bearings and journals also show damage. This was after only 20 minutes of "proper run-in time" and will require a complete rebuild again due to "metal fouling the oiling system".

I don't pretend to be very knowledgeable in either engine wear or oil but does this seem realistic? Apparently the Valvoline VR1 racing oil (and others) is said to have the correct amount of the stuff but the article doesn't mention what that is to be on the lookout for.

i posed the zinc question to the Shell rep who comes to the garage where i work, and he told me that Chevron Delo has the highest concentration of zinc, even more than Rotella. The Cummins diesels i run have flat tappets and mechanical lifters, so i plan to switch to delo and see how it works.

I have been running a 20w-40 in the PV8 which has kept the engine happy and lifter noise free, but i may switch to delo 15w40 next time.

I tried running 10w-30 last summer as an experiment, but it seemed to thin out too much, and the lifters started to tick.

Classic Car Motor Oil, 15W-40, sold through Indiana Region of the Classic Car Club of America, made by DA Lubricant Company, and sold by the case.

Hi. Don't know the availability for specialized oils in your area. I use 30w Rotella in my '53. I tried a couple of other "newer" types of oil and got all sorts of rotten results. Lifter knock, oil burn, oil consumption (my engine was eating up about a quart every 50 miles!). Put in the Rotella and everything got better. Rotella is usually available at most part stores. I can even buy it sometimes at Wal-Mart!

I too use diesel 15w40 in my old cars, anything that doesn't have roller lifters...usually Valvoline Blue or Rotella, I can get both at Auto Zone. Valvoline is available in both Synthetic and Dino, but I use the latter.

The best info I've seen anywhere on oil and additives is on "Bob is The Oil Guy" aka BITOGhttp://www.bobistheoilguy.com
Great site.
