Buy a sheet of gasket material at any auto store (tell the guy at the counter your use). Make your own using an exacto knife. Apply a thin film of gasket sealer. It's worked for 40 years on tens of thousands of cars....so it must be OK .

usually when these engines register that high on the temp gauge the heads are warped and the head gasket no longer functions. I'd wait for the new IAC gasket and see if it solves the issue, if it doesn't then your head was warped.

Sounds like you fried the engine, white tailpipe smoke doesn't just go away.

IAC uses an oring style gasket, use nothing but an oem. No silicone or home made gasket, the surface of the IAC will not accept it.

I hope the engine didn't run long enough while hot to fry it... I bought the gasket from Honda and picking it up tomorrow. If putting the gasket back on and flushing the coolant doesn't return it to normal, I suppose it is safe to assume the engine is fried?

I'd check the oil for coolant, and the coolant for oil. If you got coolant in the oil the engine will be in bad shape.

You should do an oil change before running it any further when you get the IAC gasket installed.

If you get the engine up and running and it seems worth saving you will need to bleed out the air that likely caused the overheating in the first place or it will just return again.

There is a slim chance that the white smoke was being caused by coolant being ingested through the intake manifold, worst case scenario it was getting into the engine through a failed head gasket.


Good luck with it, keep us posted.

Ok so I changed the coolant, did an oil change and when I was going to start the car to finish the coolant flush, it won't start. I tried jumping it with another car, but it still wouldn't start. I can hear the motor trying to turn over but it just won't go.

When I changed the oil, I did not notice milky oil so hopefully that is at least one good sign. Now why isn't my car starting?

Checked the spark plugs, they look fine maybe a little black, but they're fine. Now I'm thinking maybe the ignition coils went bad.. Two days ago when this all started happening in order to start it I had to give it gas for it to turn over and even then it would take a little extra to start. But I thought replacing that gasket would help, guess not.

Do you hear the fuel pump priming when you key on? How old is your battery and has the car been sitting a while? If both of those things check out, then you'll need to do a compression check, as I think you may have warped the head bad enough to where it's basically killed the engine. Plan on getting your head pulled and milled, then replacing the head gasket.

Yes I hear the pump, and it has only been sitting for one day.

DRY, COLD Compression test:

Cylinder 1: 185
Cylinder 2: 180
Cylinder 3: 180
Cylinder 4: 105

After adding a spoonful of oil, compression on cylinder 4 jumped to 145~150. Would this be enough of a difference to indicate fried piston rings? Or something worse?

Well I just got the battery tested @ AutoZone.
Results: Bad Battery, 12.5 V, 65% Charge.
Ok so there's my starting problem, hopefully. I'm going to go to Honda tomorrow and get an oem replacement. Now as for the compression results, I'm stumped as to what could be causing the low compression in cylinder 4
