The oil level was good no sign of water on the dip stick. It didnt seem as black as the 240D.
I fixed all the leaks replaced filters and swapped primer with one that wasnt leaking. valves were a little tight not bad I adjusted them 2 exhaust valves were still good. Pulled the vacuum pump it has the old style with the open bearing but looked new . It still had the cages and spun smooth. I also pumped it on the bench no odd noises.
Reassembled the motor and tried to start it. As soon as the glow light went out it fired but only stayed running with the starter engaged. I did get it to stay running for less than a minute but you would hear the screeching noise and the engine would die. I removed all accessory belts but when I try to start it the screeching still remains . The engine turns over hard when the noise is present. I'm guessing internal now.
While doing the valves I noticed everything inside is brand new. Springs adjustment nuts cam tower and cam. You can even see the machine marks in the cam lobes. New chain new guides even the freeze plugs. It looks as if it had a long block put in it not to long ago. No record of it though
The screeching is making me wonder if its not a rod or main. Maybe the oil pump? If it was would anything show up in the oil filter? anyone have any ideas on this ?
Tomorrow I'm going to try an electric fuel pump to rule out the mechanical one but I think the screeching is the key to my problems.
Thanks for the help
