watch that :D

 

 

Should tell you every thing you need to know. Take notes if you need and give it a shot! Take pics along the way in case something goes wrong. I just built mine after watching that video, havent started it yet but it looks just the same as hainz did

remember that all donations are a tax write off..

 

 

yea right, tell that to IRS.... :D

 

 

 

 

now watch, someone will be searching for "IRS" and come up with this thread. lmao

If the chain is stock (has the little white marks) you should have no problem. :)

 

If I ever have to adjust timing on my L, hainz can expect a check in the mail. ;)

ok i got it started but it is leaking some oil from whatappears to be the head gasket some one told me factory tork is to low on those head bolts and instead of 4lbs i should go 48-56lbs what do u guys think

[izzo]

i dont know what factory torque is?

 

 

Best bet, get a nice clean surface on the head and the block. super clean and smooth. Look for any signs of cracks or warpage.

 

 

after making sure its super clean, and smooth +flat. Get a head gasket, you can buy this copper spray stuff at your local auto parts store. its around 8-9 dollars depending, maybe less

 

 

Spray your head gasket with it, both sides. let it sit for about 4-5 minutes andi t will tack up. after doing that put it on the block, line it up, then put the head on and make sure its still lined up. it will still be sticky

 

 

once you do that, you torque as followed starting on the SPARK plug side

 

Torque bolt one, then two then three etc, as listed below. And torque it in 20lb increments up to 60lbs. 20, then 40, then 60...

 

10 6 2 4 8

*9 5 1 3 7

who is this someone??????????????

[izzo]

oh yeah, i just did my first engine build off some guides on here, and hainz' video. super easy man. i watched his video again after build and realized i missed a step (didnt put some oil in the oil pump before re-installing)

 

but thats easy enough.

(didnt put some oil in the oil pump before re-installing)

 

A new Motor can be a Junk motor pretty fast

Yeah i heard you say some people end up finding metal shavings in there oil afterwards. I havent put hte motor in anything yet its still on the engine stand, so itll get some in there before it gets ran :D

[matt w.]

factory spec is 60 lbs? and the guy that told me spec is too low is a nabor of mine he owns two waggons and used to race trucks

I think the Honsowetz book says to torque head bolts to 70. But that is 'race spec', and using the high spec 'turbo' head bolts with the groove in them. I stripped my new oil pump before putting it on the motor - it was also full of fine aluminium shavings. I washed it out with paraffin. Pretty poor quality control sending out brand new parts without cleaning them...

[datzenmike]

The L20B is about 60 but if you have a stock L16 it's less than that. I don't remember but around 50 is a guess.

 

Either you didn't hear him right or stay away from your neighbor.

[Buzzbomb]

I torqued my L20B head bolts to 55 ft/lbs, trying to compensate a little for possible wrench +/- readings.. Check the guide below, it states 54 lb/ft for L20B. That guide is as authoritative as it gets, IMHO, especially considering gaskets made with newer technology.

I found this link from the Victor Reinz website, BTW.

Correction:

Honsowetz says

• stock head bolts - 55
  
• grooved head bolts - 61
  

Datsun Factory Manual:

• L16 - 43.4
  
• L18 - 61.5

10 bucks?! :eek: WTF! He got me for $20 and halfa pack of smokes back when I was trying to fire up my old L20. :D

[banzai510(hainz)]

20$

Most people would say,

Can I make Payments on that 20$!!!!!!!!!!!!!

1. Make sure you dont' have a Printo-Seal gasket.

2. Torque in factory pattern, and factory steps. to factory levles.

3. Head and block face need to be absolutely clean. No oil or water on either.

4. Head bolts and bolt holes need to be absolutely clean - no oil or water in the bores. And bolts should not be oiled.

 

Blown or leaking head gaskets 10:1 are caused by not following these steps. Not by 'warped' heads. Nissan says the head can be warped 0.004 inch and still is acceptble.
