Thanks again for running the possible scenarios with me. Thanks also for conforming the the rear engine seal can be fixed without pulling the engine. The second question is yes we have not yet pulled the fuel pump and based on the photos in the manual it is the correct one however it may not be the problem as the carburetor also could be leaking.

Thanks for everyone's suggestions, we shall see what we shall see tomorrow.

Welcome to the forum..one last question for me to ask..

I put in five quarts of regular oil before the noise, then removed a quart and added MMO. I have since added 1/2 quart extra of MMO and it again stopped the clicking for a few moments. Should a bad bearing start and stop and what about the increased engine vibration? Even with the click before I started you could put a glass of water on the air cleaner. I have also had the mechanic try an engine flush and put in some super lubricant that he suggested and it seems to be getting worse.

Thanks for all of your suggestions. Shorting the plug is a good idea and will try it as well as pulling the valve cover. Dropping the pan unforunately has been met with the "how the hell" look from the mechanic and is beyond me as it has been discribed earlier (not an easy job and I am less than a novice mechanic) if the confirmed problem of the leaking rear engine seal requires an engine pull could the pan be them checked and not mess with the stabilizers or starter motor (two things that are at this point not wrong with the car). If you tell me to paint myself blue and run in a circle I would at least think about it if it could help. Does the engine need to be pulled to fix a leading rear engine seal? To answer the question about the oil pressure, it increased slightly after the MMO was added and the engine seemed to run smoother. Since then there is a definite side to side movement as perhaps one cylinder is not firing???

The Packard had a frame off restoration in 1990. From the photos it was a real mess. It appears to have been resembled nicely and been driven afterwords in a Southern town for a number of year and in storage for a couple more. Milage is estimate at 65K, looking at the engine and underneath it is clean and well assembled. Sold to us with a "strong engine". The engine was started and ran smoothly however we never drove it beyond putting it on the trailer, jumpy brakes and the fear of unknown fluids kept me from taking it out. The noise only occurred after the oil change and radiator flush and stopped for a few moments after I added a quart to MMO. Does the engine need to be pulled for this and does it need to be pulled for a leaking rear engine seal?

The saga continues with the engine noise. I have tried all of the suggestions and the sound disappears only for a a few moments. It looks that the noise is not coming from the lifters as I have been told by another "expert" that it coming from the connecting rods. That involves pulling the engine and he suspects that the gas leak has "washed" the bearings. Anyone have any thoughts on this? Thanks

I am frustrated also by the "expert" mechanics, I tried the MMO as suggested but could not find the diesel. I therefore only put in one quart of MMO. She started with the lifter click but within seconds it was gone. Five minutes later the clicking was back but closer to the front of the engine. I drained out another half quart and put in the same MMO. Still nothing. The car is level on front risers and I just let it idle should I reve it up or try more MMO or even the Kerosine or drive it gently for a few miles? What is the level of damage that I could be causing. Could a short blast of air from the compressor into one of the outlets in oil filter clear the clog. What really is on the other side of the Moon (sorry wrong forum) Thanks

Thanks, have you gotten tired with this question? Growing up in South Florida I did not see snow until I was 16 much know about heaters or heating oil. To me a home heater is a .357 in the night table .

Ok..so let me make sure i understand this right.
I put off road diesel GAS into the engine oil with the marvels and the 10w-30?
