So, what’s a camshaft seal anyway?
Alright, so you’ve dropped in because you’ve got oil under the car, or maybe someone’s told you about a camshaft seal. Let’s break it down. The camshaft is a key bit up top in your engine, helping to open and shut the valves so fuel and air can get where they need to go. The camshaft seal – well, that’s a chunky little bit of rubber that stops oil gushing out the end of the camshaft, basically where the top of the cylinder head meets the valve cover. No fancy tech stuff, just a real workhorse part. If you fancy reading a bit more detail, here’s a good rundown on how camshafts work.
You see, those seals cop a hiding, especially here in Hamilton. We’ve got every season sometimes in the same week. Searing heat on Avalon Drive in summer, or that freezing fog on the way out to Tamahere in July. That seal sits right near the engine where it’s roasting hot. Add in Kiwi roads with all the stop-start traffic along Te Rapa Straight, potholes in Hillcrest, or lumpy speedbumps around Rototuna High – things wear out. Eventually, the seal hardens or cracks, and next thing you know, there’s oil where it shouldn’t be.
Signs your camshaft seal’s carked it
Oil leaks you can actually see: This one’s a classic. You might spot a dark patch of oil under your Nissan X-Trail after parking up at The Base, or see oil collecting along the sides of your trusty Mazda 6’s engine. Some folks pop the bonnet and notice fresh oil all over – not flash.
Burning oil smell or smoke: Had a lady in from Cambridge last month with her Volvo XC90 – oil dripping onto the exhaust, making a stink and puffing out smoke. If it gets onto something hot, you’ll spot it pretty quick, especially when you’re stopped at lights on Grey Street.
Oil warning light pops on: Modern cars like Hyundai Ioniqs or Toyota Wish will flick the light on if the oil’s low. Don’t ignore that! If you keep on cruising to Morrinsville with that light on, you’re asking for trouble. Full story about this here: Oil warning light diagnostics in Hamilton >
Strange engine noises or misfires: Had a Honda CRV in from Ngaruawahia with a dodgy cam seal leaking onto the timing belt. Made the engine sound real weird, and even caused a couple of misfires when oil got near the spark plugs. Not ideal when you just want to zip down Peachgrove Road without hiccups.
Why you want to sort an oil leak – sooner rather than later
Look, dodgy camshaft seals are common on high-mileage Kias, old Subarus, even some European stuff like Peugeots or Skodas that we get through the shop. It’s tempting to leave it for a bit – “she’ll be right” – but you’re playing with fire. Oil keeps everything running smooth, and if it drops too low or ends up in the wrong place, shiny engine bits grind themselves to pieces. That’s how you go from a cheap seal job to a blown engine or worse. Nobody wants to pay for a new motor for their Suzuki Swift just because of one little leaky seal.
