Is it dangerous to drive with a cracked exhaust manifold?

Yes, exhaust leaks can allow carbon monoxide to enter the cabin (a serious health risk) and typically also trigger a lean-running condition — repair promptly.

Can a cracked manifold be welded instead of replaced?

In some cases yes, a specialist exhaust shop can weld a crack, but on a badly cracked or warped manifold, replacement gives a more reliable long-term result.

What is the manifold made of?

Cast iron (traditional, heavier, but very durable) or fabricated steel tubing (lighter, often used on performance applications).

What is this part and why does it matter?

The exhaust manifold collects exhaust gases from each cylinder and channels them into a single pipe leading to the rest of the exhaust system.

Frequently asked questions

Repeated heating and cooling cycles cause metal fatigue over time, particularly on cast iron manifolds, which are more brittle than the flexible steel of the rest of the exhaust system.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
