Summer is almost here -- Time to pull the old car out after a long winter's nap and go touring! But wait, before you fire the 'ole girl' up and take her for the first spin of the new summer, one question - When's the last time you changed your engine oil? Did you know the average vintage car or truck typically travels fewer than 1,500 miles per year. And, considering the most common school of thought for engine oil, which is 'change it every 3,000 miles' -- You should be okay, right? We think not.
When considering the life span for engine oil in older vehicles, we suggest you use time in the crankcase and not mileage to determine when an oil change is necessary. Oil in a vintage engine that sits idle over the winter can break down from the residual gas, dirt, and other contaminants generated from running. Regardless of number of over the road miles, engine oil should be changed between six and twelve months. Several quarts of oil and a new filter are certainly less expensive than a premature engine failure caused by oil that's lost its lubricity. ENJOY THE DRIVE!
Proper oil pressure is necessary for your engine to function efficiently. Remember, oil is the lifeblood of your engine. If you've noticed a drop in oil pressure i.e., oil pressure gauge (needle) hovering lower than usual or a red flickering light on the dashboard, you should inspect your engine and immediately begin troubleshooting to source the problem. Below are a few of the 'likely suspects' to look for to help you combat this common problem.
Oil pump pickup screen - Look for any dirt or debris clogging the screen and/or blocking oil flow to the pickup tube. This is usually the main cause of a sudden drop in oil pressure and (also) a simple repair you can do at home. After inspecting the screen, check the pickup tube to ensure it is positioned correctly to enhance oil flow.
Oil pump - Perform a full inspection of the oil pump. Open the pump cover to check for excessive clearance between the gears, scoring in the housing, broken teeth on one or both of the gears or the housing having any cracks in it. If the oil pump is showing noticeable wear of the gears, you can purchase a new or newly re-manufactured oil pump from Egge. Pump rebuild kits are also available for some applications if you are a true do-it-yourselfer.
Bearing clearance -- OK -- So you've replaced/rebuilt the oil pump, cleaned the pickup screen, and repositioned the pickup tube and there's (still) little or no improvement in oil pressure -- now what? The next phase is to inspect your rod, main, and cam bearings. Excessively worn bearings can (also) cause a drop in oil pressure. Check the clearances of the bearings and crankshaft/camshaft journals for wear. If the crankshaft journals are out of tolerance, the crank will need to be reground and fitted with new undersized bearings. Tighter bearing tolerances will improve oil pressure ratings.
Remember - These are just a few of the likely causes for low engine oil pressure. Also - we suggest you call Egge or consult your local automotive machine shop if you're having these kinds of challenges.
