  • Engine: Oil spray leak

    Amazingly all of the fluids in and everything’s buttoned down, the car with the completely rebuilt engine actually started up. I’m still talking about my 1952 Studebaker commander Land Cruiser three speed manual overdrive. As I gave it some gas while sitting in the driver seat and watching through the crack of the opened hood I could actually see oil spraying all over. I turned it off luckily it did not have any near amount of time to get hot I guess it ran for five seconds. My problem now and the help I need is suggestions on where I might have gone wrong. The oil level is right at the add 1/2 quart level which I did on purpose. I was very careful I thought at least with the valve cover gaskets, all of the gasket retainers are in place inside the valve covers. Is it possible that the valley cover, that thin plate could be the source of the spray leak? I’m estimating in a few seconds I had a half cup of oil come out a lot of it collected on top of the valley cover and sprayed over on the driver side valve cover and on the fender well. Thank you in advance for any ideas you may have everything else is amazingly great good spark good cranking pretty good running although the timing is off. And that will be a problem in the future because my distributor hold down clamp was missing I can’t seem to find one to purchase so I had to use a bent washer with a bolt to try to hold it in place. Much appreciated your consideration and sharing your expertise even guess what it could be thanks in advance, Roger Click image for larger version

    With my '51 Commander it was the tube to the oil pressure gauge. It comes off the engine on the passenger side near the fire wall. The rubber portion can have a small crack and although it is on the passenger side it can spray all over in any given direction when under pressure. Turner brake has a great replacement for short money. These seem to be notorious leakers especially when work is done that moves them around and leaks are hard to see when the engine is not running.

      Only a guess, but is it possible that the oil pressure line going from the rear of the engine to your oil pressure gauge came loose or was cracked? Easy to check, but if so, can create an enormous mess in only a few seconds. I was also thinking of a leak at the oil filter, but I didn't see an oil filter in your picture. In any event, most likely a small problem and one easily fixed. Best of luck.

        I too vote for the oil pressure line or connection

          A replacement can also be obtained from Studebaker International. I keep a spare in my glove box just in case.

            Your small 1/8 pipe plug is missing at the front of the engine

              Mr. Altair NAILED IT!!!! I had already replaced the flex line for the oil pressure prior to starting the engine so it was not that. I think the 1/8” plug is the culprit as most of the oil is deposited on that side of the engine. Thanks to all who contributed now and in the past. Thank you Mr. Altair of BC!!
              Unfortunately another problem, another post coming now, has to do with starter. Roger

                In my experience, the tube to the oil pressure gauge may not leak at idle, but will spray a lot when the engine revs increase. If that is your problem, use the new reproduction tube available from Studebaker vendors, and not a NOS tube. Even if unused, the rubber on an NOS will be brittle.

                  I think if you look at the picture that he posted with the problem you can see the missing oil plug location on the cylinder head.....yes - no ?

                    Absolutely that’s why I posted “nailed it”, he was absolutely right that plug was left off that is my problem. Thanks to you all very much

                      There is also a missing bolt in the intake manifold.

                        I thought the same thing but when I look down there I’m not seeing any hole with threads but I’ll have to check it again tomorrow thanks for the heads up

                          Thank you Mr. Altair. I'm sure I'm not the only one who learned something valuable tonight. And so much of what I've learned on the Forum is stuff you will never learn in the manuals.

                              The open 1/8" Pipe thread hole is for the Fram Oil Filter that can be added.

                              It is possible that the Intake is a '55 to '58 259/289, that used the end Bolt Holes.
