What’s an Exhaust Manifold Gasket, Anyway?
Ever pulled up to our workshop off Te Rapa Road and one of our techs starts talking about your exhaust manifold gasket? Let’s be honest, most folks don’t usually think about this bit unless something’s up. But it’s a pretty important part that keeps the noisy, smelly stuff from sneaking out of your engine — especially important if you’re crawling through Hamilton’s morning traffic or bouncing over potholes near Rototuna.
So, quick rundown: your exhaust manifold is bolted straight to your engine cylinder head. Its job is to grab all those hot exhaust gases from the engine, then shove them down the pipe to your tailpipe. Sitting between them is the exhaust manifold gasket — a tough little seal that stops those dangerous gases leaking out where they shouldn’t. Think of it like weatherproofing, but for your engine. And with the hot/cold, wet/dry weather we get round here, from those cold foggy mornings in Cambridge to a scorcher driving over to Morrinsville, that gasket cops a lot of stress.
When it gets worn out, all sorts of hassles can kick off. For one, gases can make a sneaky escape before they even hit the catalytic converter, which can bump up your emissions. That’s a fast way to fail your next WOF in Hamilton. Or worse, if those gases sneak into your cabin while you’re stuck on Ulster Street with the air con recirculating, it can be a real health risk for whoever’s in the car.
How Do You Know If the Exhaust Manifold Gasket’s Let Go?
You don’t need to be an expert to spot something’s off. Here’s what we see in the workshop all the time:
- Hissing, popping, or ticking noises – You might hear it when you first fire up the car. Especially noticeable in hybrids like a Toyota Prius or when that Honda Accord lady from Tamahere comes in complaining her Jazz sounds like a steam train leaving the station.
- Burning smells – We’re not talking someone’s left their pies too long in the glovebox! If the leaking exhaust starts melting wires or cooking nearby plastic, you’ll cop a weird burning whiff. Had a Volkswagen Golf in just last week, bits of the loom were getting toasted.
- Sluggish engine or acceleration – Little Suzuki Swifts or the odd Peugeot can feel gutless when the seal’s gone. And with all those stop-starts around Chartwell, you’ll really notice it.
- Worse fuel economy – You’ll be filling up more at the BP on Victoria Street when the engine isn’t running sweet.
- Check Engine Light – Maybe the most obvious one. That orange light loves to pop up if the manifold gasket’s leaking, no matter if it’s a Mazda, Nissan or even those SsangYongs you don’t see every day.
Can You Keep Driving With a Knackered Gasket?
Technically, yeah, you can keep driving for a bit. But we wouldn’t recommend bombing around Hamilton East or taking the Waikato Expressway to Raglan with a leaking exhaust gasket. You’re breathing in nasties, the engine could start running rough, and you might do even more damage to your pride and joy. Not worth it.
