I own a Land Rover Discovery II 2004, 109,000 miles, and blew a chunk of front cover gasket out last week, causing me to lose oil like BP in the Gulf of Mexico. Made it home a few miles away, no funny sounds, although oil was extremely low. Replaced the gasket with The Right Stuff, and not a drop of oil leaked out of the cover on starting up, but my oil light came on again, even though the oil was full.
I had not primed the oil pump on putting the front cover back on (it’s in the front cover), as I had replaced the oil pump just a few weeks prior and primed it then. I now understand I maybe should have packed it with vaseline again.
So today I turned over the engine several times with the spark plugs disconnected to prime the oil and started it up again. Oil light didn’t come on right away, but after about thirty seconds it did.
I replaced the oil pressure switch and oil pressure light did not come on at all, after running it several minutes. Felt really great. Turned it off, went to grab something and then take it for a test drive, and on starting it up again, light came on! But when I revved the engine, sitting in my driveway in Neutral, it would go off. Just on idle it came on. So I revved it up a little to get the pressure up, and drove off and the light stayed off completely on my test drive of about ten minutes, low and high speeds, not coming on again at all, even at idle.
So my oil light seems to be off for now, but I’m not confident.
I smelled a little bit of burning oil on pulling back in to my driveway, but this may have just been some residual oil on my frame and car, right? Temps on the Rover get up to 200.
Could my new oil pump have gotten cracked by running out of oil last week? Does that happen from low oil?
Any ideas on how to be sure I’ve fixed this problem for good?
