Could anyone show a picture of the holes in the H22 head which should be blocked while building H22/F23 hybrid, please?

Is it possible to tap them and plug with some stainless steel plugs sealed with hondabond? I really don't like the 'hondabond alone' idea there.

Thanks for your help in advance

 

I don't have a pic but it's the two drains closest to the timing belt side of the head. One on the intake side, one on the exhaust side.

 

Just to confirm


Is that correct? Thank you

 

hahaha. That head is familiar:

But yes, those two drains need to be plugged.

 

yeah you know, it had to be the very special head to make you interested enough to answer thanks again

 

I wonder if thats why I have an oil leak running down the front of the block.....

Hondabonded the rear, but left the front untouched

 

OK, as I mentioned above I didn't like the idea of hondabonding these holes at all. So I took the head to the friend machinist and we made screw-in plugs.
The head is just to be cleaned and refreshed so don't worry about its condition. Of course the plugs will be sealed.

 

I thought about doing that too. But I've had really good luck with Hondabond and close-fitting plugs in the past.

Nice job.
