I haven't been on in a while but ne ways, I have an S13, (93 240 sx) Right? ne ways thats what i've been told. But i was just wonderin, I have over 190k miles on my car and it is still running beautifully, but it squeals from 2k rpm on up, i thought it was the fan clutch and i replaced it, but it is still squealing, so im replacing the belt, it looked kind of damaged, ne ways i was wonderin what could be the causes of this, and i need to know how to adjust my valves, i have a stock ka24de please help me.

Belts wear over time, and they usually squel when either they are warn down, or they are on to tight or to loose.

As for valves, have no clue

Sirikool

squealing can also come from the AC sometimes (when it's on). happened to me. check ur fluids?

How do you know your valves need adjusting?
What symptoms are there?

I say this because it isnt something an "amature" can do.

i went out and changed my belts and it stopped the squealing, as for the valves i figgered it out too i have a breakdown manual for my car i found a while ago so i have all the original valve adjustments, and measurements, just had to look. But thanks for the belt, I changed em all, and it dont squeal ne more

...had a convo about this the last meet... DOHC's valves can't be adjusted - they have to be reshimmed or something like that... only the SOHC can be adjusted because they're mechanical, whereas the twincams are hydraulic.

If you need a copy of the Factory FSM, search around the forum (it's here) or go to the "Galley" section of www.tougepirates.com and you can DL it there for free as well (shameless plug!)

That would be adjusting them

You have it backwards. The SOHC's are non-adj because of the hyd lash adj.
The DOHC's are adj by using shims.
here are a few pics I snapped of a SOHC i'm about to rebuild.
Notice the valve how it goes" up inside" the rocker arm. Well in that rocker arm is the hyd lash adj.
The DOHC are adj by using shims.


Kinda crappy pics. But shows what it needs to.
