Quick yarn about oil leaks
You ever pulled up on Kahikatea Drive or parked up in Te Awamutu, headed back to the car and spotted a puddle under the engine? Not water from the A/C — we’re talking thick, brownish oil. If that’s you, mate, don’t just wipe it up and hope for the best. Oil leaks are actually a big deal and super common for cars hitting the roundabouts in Hamilton and all the stop-starts through Frankton or Rototuna. We see them come through our doors all the time, from trusty Honda Fits, Mazda Demios, to the odd SsangYong or Peugeot wagon.
Oil is basically your motor’s lifeblood — it keeps everything inside moving smoothly, less friction, less heat. Run low ’cause of a leak, and things inside the engine start wearing out way faster than they should. We’ve even seen a tidy, late-model BMW 1 Series in from Cambridge for a WOF Hamilton check, only to find the engine running way hotter than normal — turned out she’d been losing oil onto the driveway for months.
Here’s a bit more about what happens when oil goes missing
What usually makes the oil leak out in the first place?
There are a handful of spots oil sneaks out. Usually, it’s nothing fancy — just wear and tear. Common ones we see:
Engine seals past their best – Every engine’s got rubber or silicone seals trying to keep oil in. Knock a curb in Hillcrest, or just from years of hot Waikato summers and freezing winter mornings, those seals dry out and start letting oil past.
Oil pan or sump damage – Speed bump too quick down Ruakura Road, big pothole out Morrinsville way, next thing, you’ve dented your oil pan. Even a loose or perished gasket can let oil drip.
Dodgy sump plug washer – Not just old Falcons, either. We’ve seen Toyota Prius hybrids from Ngaruawahia in for a hybrid service, and the washer on the sump plug had squashed out, so oil was creeping out.
Head gasket issues – Look, head gaskets aren’t just for Holden Commodores. If you’re seeing weird white smoke out the tailpipe as well as low oil, check this link for more: head gasket drama explained.
Rocker cover gasket leaks – All that expanding and shrinking with Hamilton weather and running errands around Chartwell can break down a rocker cover gasket. Oil sneaks out, dribbles down the side of the engine.
Oil filter not on right – Seen it plenty, especially after a DIY oil change on a Subaru Legacy or a Kia Carnival. If the filter’s a bit loose or the seal isn’t sitting straight, oil’s gonna pour out.
How do I spot an oil leak before things get ugly?
Some signs are dead obvious, some sneakier:
Puddles or stains – Brown or black pools on your garage floor out at Tamahere or even just sticky dribbles down the driveway.
Engine running hot – Traffic on Anglesea or the slog through Dinsdale, you notice the temp gauge climbing higher than usual? Not always coolant — could be your oil running low.
Oil warning light – Ignore it and you’re pushing your luck. If that dash light comes on, it’s probably not just a dodgy sensor.
Burning oil smell – Open your door after a drive to The Base, and there’s this whiffy, burnt-oil reek? Oil’s probably dripping onto the exhaust. Not good.
