Well as the title says is all gone tits up.
I started my rebuilt engine yesterday and broke in the cam, today was supposed to be the first drive. I decided to check the actual oil pressure so I pulled the pressure switch and connected my gauge. There was no pressure even at 2k rpm. The pump is working but there is no pressure. Obviously the oil must be going somewhere, if the high pressure relief plunger is stuck open would this explain what's happening? Appreciate some help |

So, what was the problem? Do you think there was any damage done, or still not sure?

So, what was the problem? Do you think there was any damage done, or still not sure? seriously, what was the problem? Well I made a major mistake while pulling the oil gallery plugs. just before I was about to drill a hole in one of the plugs the phone rang and my wife started going on about what I was going to cook for dinner etc. After I got off the phone I suffered a complete meltdown in concentration and drilled into the case in the wrong place (entirely my fault). I drilled one of the plugs located on the side of the case by the passage for the oil relief piston. I realised the mistake immediately although I was not aware at that point of the consequences. To cut a long story short I drilled out the case threaded the hole and inserted a metal plug. As the relief piston was not installed I did not realize that the plug was too long and stopped the piston from seating in the closed position. (IMG:http://www.914world.com/bbs2/uploads_offsite/i1300.photobucket.com-17452-1431983973.1.jpg) This picture was taken after I had removed the engine to find the cause of the problem, the oil relief piston is clearly visible. Yes I do feel pretty stupid but I guess shit happens. I installed a shorter plug so the piston is now free to travel. The engine fires up no problem and as I said I have 60 psi at cold idle dropping to 20 when warm. I just hope the cam and bearings are ok. I will take the car for a drive during the week and see how it feels. During the rebuild the flywheel seal did not go in straight so I tapped on the other side and got it square (I thought). I now have a steady drip from the observation slot under the fly wheel. I plan to replace the seal if the engine runs ok. I will gladly take advice regarding the correct procure for installing the seal so I get it right this time The engine build has been a painful as well as educational experience....I guess you would call it learning by doing. Hopefully my next build will be better. And thanks to everyone who has taken the time to help me out, I do appreciate it. |
