Hello everyone, I'm new to the forum and I have a question about a diagnosis I got from the Honda Dealership. I took my 91 Civic in to have the fuel system pressurized b/c it has been smelling like fuel for a while now. They told me I needed a new tank and lines and that I had a major head gasket leak. I asked them how they determined that the head gasket was leaking and they said that when the took the rad cap off, fluid shot out. They said that this was a sign of back pressure in the coolent system because of a head gasket leak. I haven't noticed any power loss or oil in the coolent or vise versa.

I guess I'm asking if this is an accurate way to determine a head gasket leak, or if it's nothing to worry about?

Thanks in advance,

Adam

 

I wouldnt call that the BEST way to determine if you have a bad headgasket... but a blown HG will sometimes blow thru to the coolant system... (fairly often on a d-series)

Have you ever done a HG on your motor? because it probably needs one regardless of what they told you. There is a replacement gasket that you are supposed to use on those d-series motors... the stock one is a composite metal, and the suggested replacement is a layered metal...

you should just plan to do the gasket regardless... thats my advice. take it for what its worth.

 

I haven't done one since I got the car two years ago. Is is safe to still drive the car?

 

as long as you arent losing oil or coolant, you should be fine driving it until you can get it into the shop...
