Hi , I can`t seem to find the correct head gasket for my 89 Prelude Fuel Injection 4WS in Australia , every

gasket that I have been given covers some of the water holes up in the head & block , this is not correct ,

can you please tell me the correct one to get . Thanks

PS I forgot to say that it has a B21A6 engine fitted

I've never heard of a B21A6. Do you mean B20A6? Otherwise, you have a very unique engine. Most of the 3rd gens are equipped with the B20A5 or B21A1 so that's likely why you're having trouble finding the right gasket.

Verify your engine and then we can try to help you chase down the right part number. What is the part number of the head gasket that you got that doesn't fit?

Hi sorry you are quite right , I got my wires crossed , it is indeed a B20A6 . Honda told me that the number is

12251PK1662 or the old one is 12251Pk10131 , but looking at the diagram they printed out for me it half covers

the water holes up in the head and block .

Thanks Dave

Based on my search of the parts catalog, 12251PK1662 is certainly the right head gasket for the B20A5. As far as I know, the B20A6 only differs from the B20A5 in that it has a higher compression ratio. I've never heard of anyone saying that any of the cooling or oil lines were revised.

I can't find any reference of the old part number anywhere. Perhaps the diagram you received is just missing information?

Hi , I would like to send you a photo of my Honda head & gasket , but I don`t know how to download

my pictures to send to you can you please tell me how .

Thanks

Hi spiffyguido , sorry I could not reduce the size of the photo for the

Honda prelude form . This gasket is not genuine Honda had gasket

the only one I could get . The genuine one would have to come from

UK at a cost of $100 AUS . I tried inverting the gasket but to no avail .

the water holes are still covered . Thanks for your reply .

Duway

It definitly is a B20A6 engine with serial no 2002345

It's certainly not the right gasket. The holes don't line up at all, and it doesn't look like flipping it over would improve things. There's no way that's the right part.

Need to get some Honda genuine goods.

Thanks for your prompt reply, it looks as though I`ll have to get one from UK .
