Question about 1986 Alfa Romeo Spider
I have a 1986 Spider Graduate, recently bought from online seller. I'm also new at restoring cars. So far, I've just cleaned and re-oiled the K&N air filter, and put new gas in the tank. The oil needs changed I'm sure, but the oil pressure guage indicates a pretty low pressure, and it idles very rough, threatening to die if I let off the gas. The oil dipstick seems to indicate the oil is full. What might cause the low oil pressure, if the gauge is correct, and I am reading the dipstick correctly?
Also, the car has rust damage on the underside. What is the best way to fix this?
Please understand, all I can offer you are suggestions, since I don't have access to hands on testing. You might first change oil and filter.
If going by the oil pressure guage, low oil pressure can mean worn crankshaft bearings, as the clearance between bearings and crankshaft is what determines oil pressure.
Of course a worn oil pump can cause the same problem.
You might want to connect an external oil pressure guage to the engine to verify the pressure reading.
The rough running at this point would be hard to pin poit.
Because I do not know the extent of the rust, I can suggest that you consider having it undercoated.
Again, I can only make suggestion because you need an absoluate diagnosis.
