I was just trying to be helpful with my post, nothing else

Hi Packard Friends,
I thought I would share a quick way to siphon out the oil in the canister of your Packard when performing oil changes. Harbor Freight sells one for around $6.00, less when on sale. This has been a valuable tool during oil changes. When I'm finished I simply place all 4 ends of the hoses in an old gallon oil container for the remaining oil to drain. To me this is so handy that if I had to purchase one of these for each oil change I would !!! I have attached a photo of this item. Hope this is of some help.

Can someone give me an idea of the spark plug torque specs for a 1941 Packard ? I just don't want to over tighten and I always seem to under tighten for the fear of striping threads. Thank you!

Would like opinions from other Packard owners about how often you suggest re torquing flat heads. Thank you.

I purchased a siphon pump at Harbor Freight Tools. It is orange in color ,cylindrical in shape and does a great job of siphoning the oil out of the canister. A couple of my antique car friends suggested bypassing the filter but I guess I'll leave mine intact. I just was under the impression that they were not very effective thus my reason to bypass. Thank you to all of you that have commented on this forum.

Any suggestions on bypassing the oil filter on a 41 super eight engine. I feel that this oil filter is very inadequate and creates a mess when changing the oil and can be a source for leaks. I change the. Oil on my 37 and 41 Packards around 500 to 700 miles.

What is the best procedure to remove the oil pan bolts at the front of a 41 super eight engine, they look impossible to get to without jacking up the engine. I want to check the pan and screen for any sludge. Thank you.

I've noticed several 40 & 41 Packards have the head nuts painted. Am I correct to assume that Packard did not paint head nuts?

Thank you
