carmover Posted October 22, 2017 Share Posted October 22, 2017 The V fitting on my 25 Buick that supplies the oil gage and oil to the rockers is stripped out and broken off at the block. I did a repair with JB Weld years ago and would like to do a proper repair while the engine is out. Is there any place that reproduces the fitting? I haven't had any luck finding any thing at hardware and auto parts stores that have 2 two different size ports. Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted October 22, 2017 Share Posted October 22, 2017 Ron, I don't have the big book with me, but maybe someone call tell what years use this Y fitting and perhaps you can find a replacement. I think I breifly tried to remove it from the block but mine seemed like it wanted to be left alone. Hugh 1 Link to comment Share on other sites More sharing options...

Jim Bourque Posted October 22, 2017 Share Posted October 22, 2017 I have a spare from a 25 Master 6 I could send you. I don't know if it's the same as a standard 6? Jim 1 Link to comment Share on other sites More sharing options...
Leif Holmberg Posted October 22, 2017 Share Posted October 22, 2017 One year of Master will fit too, and that`s 1925 Master. Leif in Sweden. Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted October 23, 2017 Share Posted October 23, 2017 Jim, Yes your part is the same number that Ron needs. 1924-1928 6 cylinder. Hugh Link to comment Share on other sites More sharing options...

carmover Posted October 28, 2017 Author Share Posted October 28, 2017 Can the oil line from the v fitting to the back of the block from a 25 master work on my 25 standard? Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted October 29, 2017 Share Posted October 29, 2017 Ron, Your part number is 184914. Attached is a snip from the 25 Master parts book. They assigned a different number for the Master, and even between the models, created a pipe 1" different in length and gave it a different part number. My guess is that it will fit.

carmover Posted October 29, 2017 Author Share Posted October 29, 2017 Hugh, The one I am needing is the brass pipe from the large port on the v fitting to the back of the upper casting that supplies the rocker arms. Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted October 29, 2017 Share Posted October 29, 2017 (edited) Ron, Same thing perhaps. Your part is 172991 vs 181475. May need to put a new end on the tubing or a little more or less bend. Shown first is 1925 Standard then 1925 Master. 1`72991 is 1 year only.

carmover Posted October 29, 2017 Author Share Posted October 29, 2017 Hugh , Here is the one that Jim has and he wants to make sure it is right before he ships it.It looks just like mine and not like the master picture. Link to comment Share on other sites More sharing options...
dibarlaw Posted October 29, 2017 Share Posted October 29, 2017 Ron: That is what mine looks like for my 25-25. There will always be a bit of variation. The Master is probably longer. I can't compare since the standard engine is in NY at this time. (See my post starting up the "1925 Saga continues".) I had to re-solder the brass tubing to the fitting at the back of the block. Then make a new gasket. It took a bit of work to get that tube to connect into the Y fitting with out stripping the threads. The tough item is the correct style of the compression fitting if a new tube is needed. If the old compression fitting is in good shape it will probably seal well. There fittings cannot be removed from the tubing as it cuts a groove into the tube when it is first tightened. Note in my posts about the 3/16" tubing from the head to the rocker shaft. Part #172929. Shown in Hugh's parts book photo without the 2 compression fittings Part #152121. Link to comment Share on other sites More sharing options...
carmover Posted October 29, 2017 Author Share Posted October 29, 2017 Thanks Larry, Jim is going to send that one Monday for me to see if it will work out .I am about 95% sure I can use it. Link to comment Share on other sites More sharing options...
carmover Posted November 2, 2017 Author Share Posted November 2, 2017 (edited) I got the brass oil line from jim yesterday and today I test fitted the new upper casting to the original crankcase and test installed the v fitting and then hooked it to the v fitting first and it is about 1" too long.I was able to make some suttel bends in just the right places taking my time to not damage anything and in about 1 hour I had it perfectly installed.I removed it and the test fitted it and it installs perfecty with no damage to the v fitting or the line. The brass line will be a little higher before it goes behind the block but it is not very noticeable.
