So, just to be clear, I should have casting no. 10088113 on my 89 C4, and not to worry about my heads being prone to cracking?
Can the casting number be read without removing the heads?

Sure... Just pop a valve cover off and it is cast into the area between the rockers.

PS: Regarding cracks..

It is an article of faith that regardless of casting number, any time you remove a cylinder head, especially after a gasket failure (Because they often involve overheating), and especially an aluminum head, you at least look at the area between the valves for a crack.

It's probably fine, but it takes two seconds to clean that area up to check and be sure. If you overheat a head and crack it, that's generally the area that cracks first.. And you do not want to do the job and put it all back together only to find you missed a crack.

This is what you are looking for.. Yours are probably fine, but, you should take a quick look anyway. You do not have to remove the valves to do this, even though they did in the pic.

For a lot of jobs I like it better.. Like wiring for example. You can print out a diagram, drag it all over the car, write on it, get it filthy.. then just throw it away and print a new one next time.

Another option is to get the digital version, can be found for $30-40. However, that is typically for one specific year, sometimes two. Mine was an 86-87, it was two separate files for each year. Downside, the wiring manual was not part of this.

Alldata includes wiring.. Which is really, really nice when you are stuck and nothing but a diagram will do.

yes, indeed so both sides! Back when I was in the NAVY, was short on dough and cheaper out on my 87 which cost me in the long run. Do it right or donít do it at all man.

Default Relieve fuel pressure

OK, I have decided to seriously look into doing this myself. Got a shop manual, looking under Intake Manifold, 2nd step is to "relieve fuel pressure refer to section 6E3". looked and looked there but no luck. How do I "re;ieve fuel pressure"? thanks

It will be located in the fuel rail..

You really need to spend some time familiarizing yourself with the various components and what they do..

MAF = Mass Airflow Sensor. (Connects to your air filter)

TPS = Throttle Position Sensor. You will find it on the PS of the throttle body. It has three wires and mounts up high. Its job is to tell the computer how hard you are pushing on the throttle.

IAC = Idle Air Control. 4 Wire plug below the TPS. It is kinda like a computer controlled vacuum leak and it permits the computer to adjust the idle speed..

Go to autozone or rockauto if you are confused, and put in the make and model of your car, then search for the part (Mass Air
Flow Sensor - For Example) and they will show you a picture of what you are looking for.

PS: when you get it torn down, stop and post photos..

Forum members may have advice on cleanup or assembly tips before you go back together.

Best of luck!
