Reply to "Oil Pressure Guage"

Sure, liquid filled gauges are nice but more expensive and not vital. My $12 undamped gauge from Kragens is now 18 years old riding back there on the block, and is still more accurate than the stock in-dash gauge....
Rule of thumb for Ford engines: if the gauge is accurate and reads lower than 10 psi at idle or lower than 30 psi at 3000 under load, drive directly to your friendly engine overhaul shop 'cause it needs expert attention! A strong motor will give around 20 psi at idle and 60-80 psi above 3000 under load. Note- these numbers are meaningless with a normally inaccurate stock gauge. Many stock gauges will not show above 40 psi when first fired up, even with a new engine!
