no not the terminals themselves, the connections that bolt onto the cables and connect to the terminals whichever style the cable corrodes where it attatches to the terminal clip because it's just clamped on, not pressed or crimped with a good connection. I've seen them both corrode on the battery itself, though top terminals tend to build it up more since it all just sits on top.

Not sure if it was mentioned...but I'd be concerned a bit about WHY the head gasket blew in the first place.

Ultimately, I don't know. A few months previously, the bypass hose failed and the car got pretty hot before I caught it. This could have caused it.

I also believe that after the thousands of thermocycles the engine goes through in its lifetime wears the sealing surfaces of the HG. The CRX has a fiber gasket and it shredded when I pulled the head off so I couldn't see exactly where it had failed. My Integra blew its HG a year ago, and being an all metal gasket with some kind of black coating, you could see where the black coating had rubbed off in several areas.

I wouldn't. On Honda's, except the Si, the head gasket is just the rubberized gasket material, except for a tin ring, basically, which is at the top of each cylinder. The block is an open cast design, so the only thing holding the head is where the cylinder bores meet the head, and the outside edge of the casting.

I've got 1-87, 1-89, 2-90's which I've owned or worked on in the last couple of years. Everyone of them seems to have the head gasket just finally whimp out at around 220,000 miles or so. I've installed the econo head gasket sets and I've done one with a hi end, Si set, so the whole head gasket is enclosed in metal. I've not had any further issues from any of them. Nah, I don't drive them all, although I have. Two of them are for a couple of my children and one of them is for one of my sisters. I do drive the 89 Wagon, though.
