Hello,
New to forum, looking for some help with an oil pressure problem on a 1952 VAI Case (124 cubic inch 4 cylinder motor).
The tractor ran good for years, then sat for an extended period of time. Ran rough when restarted, primarily a carburetor problem but checked the compression and found it low so decided to do a modified rebuild. Did the carburetor, heads and new piston rings. Did not touch the main bearings. Changed oil and filter.
After I put it all back together it started right off and ran good but only registered about 2-3 psi oil pressure so I shut it down.
Thought maybe the sump suction/screen assembly may have come loose so drained the oil, removed the oil pan and checked. Found it was in place and secure.
Checked the gauge and blew air through the sensing line - all good. Checked the bypass spring found it intact and in one piece but tension seemed a bit low so I put a small nut behind the retainer to increase the spring tension a bit although I doubt this is the problem. The new filter has residual oil in in it so it appears some oil has been circulating.
Beyond the above I have no idea what else to do or check. She’s a good old girl, I’d love to get her working again.
Any advice on where to go from here would be much appreciated.
Thanks
