I have a blown head gasket in my 92 civic. Its not only blowing antifreeze out the exhaust, its spitting it out. Does any one know how much damage is done by now and is it to late to change the cylinder head and gasket? Please advise.

 

It's hard to say. You have to replace your head gasket anyways so pull your head and see.

 

no its not to late, also what do u mean by spitting it out?
where?

 

If you haven't overheated it badly the motor should be okay once you change the oil, coolant and other HG ods and ends. When you pull the head to change the HG, put a straightedge on the head mating surface and the block to check for warpage. Sometimes you need to have the head machined in order to get a good seal.

 

the exhaust

 

Regardless of the cause, take a straight edge to the head and block surfaces. Even if it isn't overheated, fluid begin forced through the gasket takes up space, and it gonna push something out of the way to get through.

I'd say prepare to resurface the head, just to be safe.

 

how often do the actual blocks on d series get messed up from a blown headgasket?

Whenever they blow.

Not as often as some may think.

I have replaced the HG on my niece's 93Si after it got hot enough top melt the plastic behind the timing belt. Had the head flatten and put it back on and drove it.

These little engines will take lot. The head gasket is easy to change once you've don't it.

Just pulled the head of the race car in 2 hours last Sunday, without air tools.

yeah seriously some of these motors can take monumental abuse if they were in good condition to begin with. I have a d16y8 which had been turbo'd for 30,000 miles at 10lbs of boost, and had redone my turbo setup and dyno'd it at 200 hp. Driving home from they dyno it was overheating badly, and it turns out the head lifted. So i took it off and the head was warped about 4 thousandths. So i threw it back on with some of that copper gasket spray and an OEM headgasket and ran it for another 10K before pulling the motor to accommodate for bigger things I've also hit 9000 rpm on said motor and it now has about 100K on it and runs great. Not saying every motor can do that, but with D series motors being a dime a dozen, if you can afford a little down time just throw the headgasket in there. But if it's anymore than 4 thousandths out then you might want to consider getting it resurfaced.
