How low? The Northstar's oil passages are huge, and with 7 1/2 quarts of oil, it doesn't need a lot of pressure. The normal operating oil pressure is less than 10PSI, and that's at 4000 RPM. If you get a low pressure warning, it's possible the sensor is bad. They do go bad, especially after a ham-handed mechanic whacks it out of place while replacing the oil filter. They're a snap to replace, and I'll bet that's your only real problem, if any. DO NOT let any mechanic who is not COMPLETELY FAMILIAR with the Northstar mess with it, or give you advice. They don't know what they're talking about, 99% of the. This is not a 350 small block here, it's a highly sophisticated race bred engine that is completely different than virtually any other engine your mechanic might be familiar with.

Where is the starter located in a 1993 Cadillac Eldorado?
It depends on the motor im not sure if the eldorado ever came with a 4.9 but i know on my eldorado it was underneath the intake manifold...which involves taking the fuelrail off and is not something i would recommend doing by yourself if your not a mechanic but if you do make sure you change the injector o rings because leaking after this is common and can lead to a bad motor fire
You have 1997 ElDorado with an oil leak coming from who knows where A mechanic said these cars have a reputation for manifold oil leaks True?
Yes anything running a northstar engine is prone to oil leaks especially if you use a synthetic oil this is because the block is made from aluminum which is more porous then steel so fluids can get past the seals in an effort to fix this gm started pressurized molding in 2000
I got a 96 Cadillac Eldorado. My Mechanic replace blown headgasket. 3 days later car ran RUFF. I had a 2nd mechanic test to see why car was running so ruff. 2nd mechanic said the HEADS were NOT SHAVED?
Very possible. Also the head(s) may be cracked. They should have been checked for warpage and cracks when they were removed when the job was first done.
What would cause a 1983 Cadillac Eldorado to stall when making right turns?
