Hi everyone
i got an old 300D 1976 115
i am having a few little problems and i'm wondering can anyone help because i absolutely LOVE LOVE LOVE this old benz..
i ran the car on veggie for a while and it ran fine.
she drove great up until recently.
now the car starts up perfectly first turn of the key..
but next what happens is no so pretty, what happens is the car warms up to normal operating temprature and as it does the oil pressure drops drops drops slowly to 15 psi then stays there for a while then drops to 0 and stays there for a a minute, then stalls, and she will not start again until the whole car has cooled down for half an hour.
There is a funny , slightly noticeable tapping noise coming from the engine as well.
sometimes the car smokes moderatley, sometimes it doesn't smoke at all.
I put some heavy weight oil in there to try and build some pressure and replaced the oil filter. it made no difference what so ever. I cleaned the fuel tank out and filled with clean white diesel, just to eliminate that for any veggie haters out there,
could i have blown bearings? or oil pump? if someone could give me some input it would be great as i dont want to let this old car slip away over to the dark side...:roll:
