My First 240sx ka24de cylinder rebuild

[OoAtreyuloO]

Hello my name is Matizzles !

this is my first nissan 240 sx
picked her up for $900 not running clean title :naughtyd:
And the reason it was not running was because of a broken cam gear(the exhaust ripped through the vlalve cover =o)

So i always waanted the coupe after i left the honda game
:dead:

So I got it home feb. 4 2011
and the first thing i did that night was to Take the valve cover off and see the damage.

I dont have pics of the damage, but to give an image, the valve cover was broken in 2 pieces on the left exhaust cam gear.

So i got to work

Jacked her up and began taking out all the radiator and fan stuff (hoses,fan shred, and ect.) and draining the fluids.

(ignore the top intake manifold half that was later when i took that off.

Took me about 2 1/2 hours in total with a friend to remove the head.(remember this is my first time ever removing a ka24de head.)

We ran into troubles taking the intake manifold ....took for ever to remove those 12mm bolts. And even after we removed them all and the bracket bolts under the manifold....it would not budge!:rant:

-_-...so we decided to remove the half top portion of the intake manifold.
Even that proved to be a pita!

anyways....so after we got the top portion along with the fuel rail and the engine harness, we removed the cams and the head bolts. That was after setting it to tdc.

and when i removed the head this is what it looked like....starting from cylinder 1-2-3-4.

apparently an intake valve was hitting...what do you guys think??

So now that im typing my head rebuild

do you guys think the pistons look good enough for a rebuild head to be slapped on? This is only a dd for now. Thank you and more updates soon!

I really need to know if the pistons look good tell me what you think and by the way the cylinder walls have no ugly grooves looks really smooth.

[OoAtreyuloO]

Help me out peeps thank you in advance!!!

[SHARKERIOcoupe]

congrats - i love coupes

good luck - keep it clean :)

[c-los13]

just replace the valves that hit the piston since theyre most likely bent!
i forgot to tighten one of the cam sprockets when i rebuilt my ka ='(
the valves hit cylinder one and it looked exactly like yours
i just took the head to the machine shop to get the valves replaced and put the head back and my ka has been running perfect =)
good luck
and congrats on getting a coupe that cheap!

[OoAtreyuloO]

Thank you sharker luk i shall need =p

c-los13

+1 on the timing covers.

When I took my block to get machined, I didn't take my timing covers. When I put the engine into my car, I couldn't get my distributor in, I was like wtf... Well, it's cause my front timing cover was a few thousandths taller than my head cause I didn't have it machined with it.

Long story short, bolt your front timing cover to the head when you get it resurfaced/decked. Everything needs to be the same "height"

[OoAtreyuloO]

thank you all for the adive im actually looking to have the head machined and probaly do the instalation myself.

for now i want her up and running till i get an sr20

And by the way im selling the stock seats really good condition for 40$ let a friend know or something.

[OoAtreyuloO]

So today really didnt do much on the motor.

So went inside cleaned her up saw this

So i decided to rip it all out and do a diy!

So a friend gave me an idea to rubber coat it like they spray the trucks cabs with!

I will be doing this tmmrw and will make a write up see how it goes!

[OoAtreyuloO]

So update on the motor
I spoke to Manny a 240 mechanic and i asked on the price to rebuild the head and said im better off getting a ka24de!
so i am really considering that and will be pulling the block off soon so if anyone needs parts let me know!

[andyv316]

thats what you have now is a ka24de. You already have a dohc 2.4 liter. he is thinking you have a sohc that came in the 89 and 90 models.:confused:

[s14freak93901]

thats a clean body. don't work around the single. swap it for a 5 speed dual cam DE.

[OoAtreyuloO]

sorry for the confusion guys but yes he is saying to get another ka24de which he knows i haveone already u know sry XD

[andyv316]
