I have an 89 Probe LX [i:77eaa260a0](non turbo)[/i:77eaa260a0] with 2.2 L.
It had quit running, but before it did, I could smell coolant in the exhaust. I suspect the head gasket had blown, so I've since began to tear it apart. I removed the head to find all cylinders had coolant in them. Number 3 had the most. I noticed some discoloration in the gasket, and cylinder walls:
Here's a shot of the head:
How do I know for sure the head gasket is blown for this much coolant to be in the cylinders?
The cylinder walls are discolored, and it needs a clutch, so I figure I'll take the motor out to make it easier. There's no ridge felt at the top of the walls, so can I get away with just honing and replacing the piston rings?
As for the head, I'm wondering if I should take it to a machine shop for reconditioning. As you can see, the #1 cylinder's exhaust valve is a bit darker than the others. I've thought about just changing the valve seals and cleaning it up in the parts washer, and then milling the deck enough for straightness. :?:
