Re: 1950 packard 288 engine just rebuilt now has water in the oil

It has lost water 3 or 4 times the last time I marked the distill water jug where it was and filled back to that level it was 14 oz . "I never put coolant in it since I have worked these type of engines in my Ag days at Allis Chalmers plus several other tractor manufacture that used this type of head gasket. We always ran water until we had no leaks and retorqued the head hot. We had a Ford tractor that had to bored oversized for pistons that once it was back together and found it was getting water in the oil plus white smoke. We were very certain we had a leak , dropped the oil pan and put pressure in the radiator you you could see it spraying out a pin hole "porosity" from being bored oversized. My engine is not that obvious Thanks for everyones input I hope My machine shop guy and I find something.

I read the post from Gene in Dec of 2020 with the same issue and started checking my engine. The engine was bored .030 for pistons , the deck was machined .005 and the cylinder head was machined .020 due to running hot before I got the car. We installed new valves Intake and Exhaust and guides on all cylinders and ground the seats the crankshaft did not need turned just polished . Here is a list of everything I have checked or tried . Water temp has run between 190 to 200 its a mechanical gauge also a new radiator core was installed with a new water pump I also checked the engine temp with a temp gun in several locations each time it was ran. I never saw smoke out the tail pipe their was some smoke / blowby from the breather tube from the valve cover under the car and oil fill but cleared up after a few short drives about 1.5 miles each time. I decided to check the water level when it was cold from the flange in the radiator where the cap seals to the water just above the core then drive it and check again the next Morning before starting it . The next day it was down about 1/4 of a inch so I filled it to the same level not to worried at this time . Then drove it again and did the same this time it was down about 1/2 inch now I getting worried . I started to do some checking compression check all cylinders 120 PSI cold then checked hot all cylinders 110 to 115 PSI. The next Morning drained the oil slowly and water came out first put in it a separate clean pan then the oil. Checked the water it was down about the same amount. "I forgot to say after two of the runs I retorqued the head ( hot ) the first time they moved about a quarter of a turn to half the next time very little. " Then I pressurized the radiator over night to 7/8 PSI and it held no loss then I did it hot it also held overnight. Now Im thinking it must only lose water when its running. Now I went to see my engine guy who did all the machine work he wanted me to try a block sealer called Irontite that he has used in other engines with success. Not wanting to run it any more but did to work in the sealer fingers crossed then drained it hot and letting it set for 12 hrs I did 24 then refill with water. Sad news but still losing water. Last check was a cylinder pressure test each piston at BDC and TDC with 100 PSI of air and listen out the oil pan drain plug no air coming out. Then put air in each cylinder and closed air supply valve leak down was about the same. Now not knowing what else to do pulled engine out and apart " the block sealant leaves a white film " was hoping to see something and found noething . Took the block and head back to my engine shop we magnaflux everything we could get to head , cylinder bores valve and seat areas and found noething . Then put the head and water pump back on sealed it up and put 30 PSI of air to it and sprayed it with soapy water could not find a leak any where when we rotated it and looked. "The inside of the intake manifold is wet all 4 locations and spark plugs are to clean water leaking from seat ??" " Please forgive me for this giant run on paragraph Im at a loss and so is my machine shop guy ". I need you Packard guys that know these engines for you help because I don,t. know them .Hope I have missed something easy at a loss of what else to check or look at.

1950 Packard deluxe 288 cu in 8 cylinder compression check
#23

I just finished a complete rebuild of the engine. New 30 over pistons, reground camshaft , new valves and guides , new std. main rod and cam bearings and new timing chain. We had to take 20 thou. off of the cylinder head and 5 off of the block deck since the engine had run hot before I got it. Just wanting to check cylinder pressure after getting it running. I have seen post saying it will raise the compression. But wanted to make sure what it should be since the Service Manual does not say. Starts good cold and restarts good hot runs down the road fine. Water temp gets to 200 deg. Have not put coolant in it yet since the block was pretty nasty from all the years of not changing the coolant. " Still running water and changing it after each short run until it cleans up ." Any info would be great Thanks.

I need the big end bore spec for the connecting rods " with out the bearing installed but the cap is torqued" I have the Packard service manual and the section in the back with all the specs it does not say. Also still looking for a good lower tank for the radiator it measures 20 1/4 x 2 inchs One from a manual transmission would best even though mine is a ultramatic I will be using a external trans cooler.

1950 Packard Deluxe 8 cylinder engine removal.
#25

I am going to remove the engine to tear it down when it got hot it must have damaged some of the cylinder packs. It only has compression on some cylinders when cranking it over. It trys to fire with a small shot of starting fluid. It looks like the support that goes around the radiator needs to be removed or cut the top off and then bolted or welded back in place. After looking at the front and seeing the support holds up the front of the fenders and everything above the bumper not sure of what is the best way to go.

1950 packard deluxe radiator interchange ?

What years of radiator will fit a 1950 Packard Deluxe with a Ultramatic transmission? Is a radiator for a manual transmission the same size and will it work if you add a external cooler for the transmission?
