Why does coolant and oil mix after a head problem?

A cracked or warped head (or a failed head gasket) can open a path between the oil and coolant galleries, letting the two fluids mix.

Does the head need to be resurfaced during a rebuild?

Often yes — a warped sealing surface won’t seal properly against a new gasket, so machine shops check flatness and resurface if needed.

What’s the risk of driving with head gasket symptoms?

Continued driving risks overheating and further engine damage — a compromised head or gasket should be addressed as soon as possible.

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

White smoke from the exhaust (coolant burning)
Overheating or loss of coolant with no visible external leak
Oil and coolant mixing (milky residue under the oil cap)
Loss of power and rough running

Installation information

Replacement requires removing the timing components and intake/exhaust manifolds, and always fitting a new head gasket — bolts must be torqued in sequence to the specified value.

Frequently asked questions

Small cracks can sometimes be welded or repaired by a specialist shop, but a replacement head is usually more reliable, especially for structural cracks.

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.
