streamer Posted July 27, 2008 Report Share Posted July 27, 2008 I just got my engine back from the rebuilder and he somehow lost the oil pressure spring and the threaded cover. I have another plunger, spring and cover from a 218 parts motor. I tried to put the plunger into the hole and found that the original plunger is still in there. I have tried to get it out - with no luck. It moves back and forth about 1/2 inch, but gets stuck at that point. I searched the forum for ways to get it out and will try those in the AM. What I would like to know is the length of the spring. The one I have is just about 1 3/4 inches. Also if the plunger moves back and forth 1/2 inch, is that enough for it to work properly?? Thanks Quote Link to comment Share on other sites More sharing options...

Thanks You definitely need to get that plunger out of there. You're going to need to get air pressure blowing from the oil gallery side of the plunger to get it to come out. I'd be a little leary of the machine work that was done. With that plunger still in the block there is a chance that metal debris could still be in the oil passages. One last thought on getting it out would be a really strong magnet. You might get lucky and it will be sucked out that way. Good luck!

dodgebomb Posted July 27, 2008 Report Share Posted July 27, 2008 I got one for ya; my motor (230) came back with the threaded cover on but no spring or relief valve. 2 sets of rod bearings later, and finally hooking up the pressure gauge, i figured it out. I had a spare block with one in it and i used a dental tool and eraser end of a pencil-no problem. I do know that there are 3 different springs that can be used in there. Maybe get some solvent in there. Good luck. Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted July 27, 2008 Report Share Posted July 27, 2008 Try using an easy out. The plunger must slide in and out easily. Once out chuck it up in a drill motor and polish it with emery paper. Quote Link to comment Share on other sites More sharing options...
streamer Posted July 27, 2008 Author Report Share Posted July 27, 2008 Thanks for the information. I got the plunger out, cleaned it up and put it all back in. As I said this spring is about a 1/4 inch shorter than the one in the picture so I guess I'll just have to see what the oil pressure is after I get the motor installed and running.

grey beard Posted July 28, 2008 Report Share Posted July 28, 2008 According to to the VPW catalog, the heavy duty spring is green in color. Didn't realize they were color coded. Glad you got that little devil out. Like bkaler said, please make certain you have no debri left in any galleys, especially if they cleaned the block with the plunger in place. Might even wanna' unscrew the two plugs at either end of the block for the oil galley and blow through the thing end to end. AND if your mains are not yet installed, I'd blow shop air through all the block passages. If you do see dirt come out when you do this, K'd consider investing in a rifle bore brush or two - they even got 'em at Horroible Freight. Just like a paint job, preparation is the key to a good job. Don't let someone else's carelessness ruin a fresh overhaul. New engine assembly parts should be clean enough to eat - not that I'd go that farrrrr . . . . . . Quote Link to comment Share on other sites More sharing options...
streamer Posted July 29, 2008 Author Report Share Posted July 29, 2008 Thanks, I will definately blow out the oil lines before the install. Quote Link to comment Share on other sites More sharing options...
