old rat 49 Posted March 12, 2012 Report Share Posted March 12, 2012 After much cleaning and eyeballing I am pretty sure that most of my leaking is from the oil pan not front and rear seals. Pulled and cleaned relief valve. It was quite clean actually. Made a block off plate for the no longer used mechanical fuel pump. Had a slight leak at oil filter line. The pan had a fair amount of sludge for a car tha sat for 3 decades and Who knows when it was last cleaned. Absolutely no sign of any metal in the pan. Quite surprized at that. My main question is this. Shoud I pull a rod cap just to check for wear or should I leave well enough alone as I don't hear anything knocking and should I drop the rear main cap and go ahead and do the rope seal. Was out running arround yesterday and put 36 miles on it with no problem and finally got to drive it at night. Those #81 bulbs in the dash make a world of difference and I love the lighted hood ornament/high beam indicator. Input appreciated. Quote Link to comment Share on other sites More sharing options...
DCurrent Posted March 13, 2012 Report Share Posted March 13, 2012 If you find that the crank needs work are you ready to rebuild the motor? I would just leave it alone if it runs fine. Darren Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted March 13, 2012 Report Share Posted March 13, 2012 What is your oil pressure reading? Quote Link to comment Share on other sites More sharing options...
old rat 49 Posted March 13, 2012 Author Report Share Posted March 13, 2012 Don; Oil pressure was running about 40-45 while driving. 20 or so at idle. Using a poor man stethascope ( a big screwdriver with the handle at my ear and the tip on the pump) I can here some noise I didn't like. Will pull the bottom plate off oil pump to give it a quick look. Quote Link to comment Share on other sites More sharing options...

james49ply Posted March 13, 2012 Report Share Posted March 13, 2012 if the noise is a knocking at idle, but not when at higher rpm, could be the relief valve opening and closing, mine does that and is not a problem. Quote Link to comment Share on other sites More sharing options...
old rat 49 Posted March 13, 2012 Author Report Share Posted March 13, 2012 OK. I'll leave alone. Made the valve all nice and shiny again. and as an added note I pulled the cover off of oil pickup/strainer to see inside and the screen itself was very much clogged up and there were three large pieces of the peel off seels from oil bottles or something in there. 1 Quote Link to comment Share on other sites More sharing options...
