Re: 443 high oil pressure - cause for concern?

A follow-on question to this topic: reading my materials indicates that if I did need to adjust oil pressure, I could do so adjusting the relief valve located within the fuel pump. My question is how to access the adjusting screw. Below are the instructions from the service manual (instructions for this operation are the same for the 6 and 8), and a sectional cross drawing from the same.

I do not read this to indicate that you need to drop the whole oil pan to access this piece. However when I remove the cover below the oil pump at the bottom of the crankcase, there remains a casing covering fuel pump mechanisms which can be seen in the illustration. None of the materials I’ve consulted suggest to me how to remove this casing, and examining it myself I cannot see any obvious way to do this. Is this a job that would require me to drop the oil pan to access the full fuel pump (not a job I want to do if it can be avoided) or is there something I’m missing here in how to remove this casing? Thanks.

Fun item for my ‘54
#3

I have a ‘54 Convertible that I bought in 2006 and restored over the next 12 or so years. It was an upstate New York car, and when I bought it I was told that it was the daily driver of the dealership owner’s wife - didn’t say which dealer.

Well, sifting through spare parts that came with it, we found a little pot metal piece of trim with “Osterdorf” on it - turns out it was Bufflo’s Ostendorf dealership, a building now on the national register of historic places.https://packardinfo.com/xoops/html/modules/dealer/View.php?ID=384

So recently I decided to get the old piece re-plated, and you can see the difference before and after. I understand it was found on the passenger side of the trunk lid, roughly opposite the “Packard” script on the driver’s side, although I don’t know the exact spot, so I suppose I’ll just attach it where I think it looks nice (unless somebody knows exactly where such a thing goes). Fun thing to be able to do given the car’s history.

Thanks John, my 443 has the same system so that makes sense. I probably should’ve thought of that.

Hey thanks TxGoat, I appreciate all the advice you give here. And yeah, the oil pressure drops when I pull out the choke, even while the engine is running the exact same speed. Once warm, it does seem to run a little better with the choke pushed all the way in but seeing it nearing the top of the gauge on oil pressure always has made me nervous - it sounds like you’re telling me I don’t need to be.

And yes, I have been reading the materials - they don’t have the owner’s manual for the 443, but they do for the ‘28 6 cylinder models, and the commonalities are enough that it’s pretty useful (the instruction manual partly what inspired the question). But still on climbing the learning curve…slowly. :)

443 high oil pressure - cause for concern?
#6

When I first start my 443, the oil pressure at idle is around 22 lbs and it quickly goes all the way to 50 lbs (highest indicated level on the guage) if I apply the throttle. Even after getting warm it seems high-ish, with the pressure at idle between 15 and 20 lbs, regularly getting to 40 lbs or above at speed.

However if I pull the choke out (say between 1/3 and 1/2) it instantly drops to much lower levels. However when I do so it feels like I’m running excessively rich, even though I probably do need a slightly richer mix because I live at altitude (in Denver).

I wonder if people think this seems like a problem and if so if there are any suggestions on how to address it?

Also, just for fun, I’m including a pic of my car with the post. :)

I just did the same - the small amount I donated doesn’t come close to how valuable the site has been for me, but at least I want bigkev to know I appreciate everything he’s done here.

Thanks everyone for the recommendations. I have a very small job I’m hoping to get done - replating the original dealer tag for my ‘54 - so I’ll have to see if any will be willing. It’d be a cool original item to have attached as my car was purportedly the daily driver of the wife of the dealership owner. Although I have no way of positively verifying that.

Who did you use and did they do a good job? I have a couple of small pieces I could use re-chromed and am looking for someplace that might be willing to take the job.

Merry Christmas!
