block to head dowels (L20B)


Dawa

Recommended Posts

im trying to find a part number or source for the dowel pins that align

the block and the head. i've heard that running without them could cause

head gasket misalignment/failure. i didnt remove them when i took them

to the machine shop, had both block & head decked, and in between that im sure

they removed them. i went back last week to see if they had any, they didnt and they pointed me towards the dealer. he also said that i could use the Z dowels.

 

so yeah, part numbers or solutions, pretty please.

They should be same as L16.  This website is awesome for part numbers.  it looks like you need number 4 part -11053-73400.

These should be in stock at the Nissan warehouse and cost about $1.00 to $1.50 each

Going to a dealer and telling them you have a 1980 720 with l20b. That will get you the part you need.

Bring back this thread because I thought my dowels were in my baggy of parts but they were not.  So I need two of them.  Tried the pn 11053-73400  but it wants you to order 10 of them.

 

 

 

I seem to remember cutting short length 1/2" copper pipe and using them.

 

Do you know about how tall they need to be?

If you have on line or paper access to that page look carefully at the line just above or below the listed part number.  Often 2 P/Ns are listed, the first for a single unit and the second for the dealer to order bulk for shelf stock.

11053-73400 about 83cents ea. Used on every 4 and 6 cylinder L, Z and B-210/210 A series

 Each site makes you order 10.  Stupid!  I think I am just going to order them threw Napa.

Not in a crazy hurry but it is the one thing keeping me from finishing my LZ

You may want to pry apart very slightly so they have to be tapped in snug.  Good going. I thought I was going to have to take my own advice but found one on the KA block and another on a Z22 head.

 

 

Maybe you should post these pictures and a write up in the How To section. It's little things like this that hold up builds and it's such an elegant and simple fix.

I had a warped head on my L20B  521 back in the '70s. Changed the gasket, it blew, changed it, it blew, swapped a 510 head on while getting the head milled and swapped it back... so 4 gaskets in a month. Got pretty good at swapping gaskets. Didn't know enough back then and lost a dowel
