Okay well I just got down with a mini-me witch took me an 1-2 hours. I have a d16z6 head on my 88 CRX DX block.

Well I was finished with the timing belt getting ready to do valve lash then the rain started coming so I put everything away. While I was putting stuff away I noticed a dowel pin (I believe thats what its called) there are 2 on the cylinder head where the head bolts go through.

Well I am just wondering if I HAVE to have them in there. I have one in place and I am hoping the dowel pin I found was just an extra from my extra can of parts (bolts, washers, pins, etc.).

Help I need to know my 90 CRX Si motor bit it and I need to put this in there to get to work.

yes the dowel pins are very important, time to pull the head back off

 

What are they used for? I am guessing oil passage?

Damn, this is gay o'well thanks.

 

they're used to align the head in the exact space, for the combustion chamber and timing belt alignment.

 

lol, well got the head off took a look and both of the dowel pins were there needless to say it was an extra Dowel pin.

Thanks for the help glad to know what they are all about
