Best way to seafoam a 4.0 sohc??

[Gianni D]

I'm planning to seafoam my X this coming weekend (weather-permitting). I read the sticky on how to seafoam a 302, but how do you seafoam a 4.0 sohc? I know I can use the brake booster, but it seems that a lot of people here don't like that method 'cause the seafoam doesn't reach all cylds ...

Any suggestions??

wouldnt the break booster get only 1 side? it would get to the back though.
you could try throttle boady & break booster.
dont forget to put 1/3 in your crank oil.

iac valve maybe...

I read somewhere around this forum to use breather tube that connects the air intake to the IAC ... can someone elaborate on this procedure??

Thanks,

The Idle Control Valve "IAC" is at the rear centre of the upper intake and is vac controlled to a wire actuator arm.
You could remove this and poor the stuff in!
You could also look at the crankcase ventilation - those lead to the middle of both sides of the upper air intake.

Thanks for the advice ...

I found the actual thread that explains this ...

Yup, best method I used when I had a SOHC.

I just completed seafoaming my engine at my buddy's place. It was extremely easy to do and I got the expected results (my friends thought I broke my engine when they saw the smoke cloud). I also cleaned my MAF and throttle body and replaced my IAC sensor.

My engine is running extremely smooth now ....

Thanks for all the advice,
