i’m troubleshooting the leaking oil in the galaxy 500 and my first thought is that a deteriorated valve cover gasket is causing the problem. the engine exhaust doesn’t smell sweet and there’s no oil in the radiator fluid so it’s unlikely to be a head gasket issue.
when i went to the local auto parts store, the guy behind the counter said he’d love to sell me a valve cover gasket ( only $20 ) but asked if i had tightened down the valve cover bolts recently.
“uh, nope. and to be honest i couldn’t remember when i would have thought to tighten them.”
“give it a try. i’ve seen valve covers so loose that oil starts seeping out.”
i went home and sure enough the valve cover bolts were so loose that i almost couldn’t believe the covers stayed on! i was sure that had to be the cause of the leak since the oil seemed to be coming in out of the bolt hole that had one of the loosest bolts. it couldn’t be a coincidence!
so i tightened the bolts, cleaned up the oil that leaked on the block and started the engine.
the result? the oil was pouring out of the same area faster than ever! what was going on? i couldn’t quite tell because it was hard to watch the oil leak and start the car at the same time but it didn’t take too long to figure it out.
while i was poking around i discovered this line appeared to be completely severed! it wasn’t obvious at all that it was severed because it was running through the clip attached to the bolt that seemed to be the main source of the leak. i turned the engine over and sure enough oil came spurting out of the lower section of line that emerged from the engine block. the line looked like it went into the main cabin bundled with a few other lines. i wondered why pressurized oil would be going into the main cabin and it took me a few seconds to come to the rather obvious conclusion.
it’s the line for the after market oil pressure gauge that sits under the dash. it must have developed a small crack right under the clip that held it in place and i broke it completely when i cleaned up the oil around the bold holding the clip.
