PCM Mark IV 454 Manual

I am looking for a manual for a PCM Mark IV 454 for my 1988 BFN. It overheated on the lake and now (or was I pulled all of my plugs and turned motor over until no more came out) water on top of three cylinders. One on the driver side of motor and two on passenger side. Anyway I am starting to pull it apart this afternoon and just wanted a reference to go back to and to also have the torque specs when i put it all back together. Hopefully I won't find anything to troubling. At least there is no water in the oil. Thanks for a great site it has been a wealth of knowledge being new to the Correct Craft world!

Thanks for the tip I took your advice and checked compression found three cylinders that had less than 80 psi. I went ahead and pulled it apart and found a blown head gasket. I'm also wondering what made it overheat. The rwp looked fine when I replaced it thinking that was what made it overheat

I have that service manual, but you aren't next door. I'd be happy to look up a thing or 2 for you. My manual came from go 2 Marine I think.

It's been a while; Pete is probably correct.

My manual says to add 5 to both figures. 80 & 30

if its got points take a file to them

If your distributor is getting 12v, your coil is good, the rotor is there and turning, and you have no spark then it is likely your module is wonky. I suspect you can change it, or if you have a need for expensive shiny things the dui wouldn’t be a bad ideal.

That's right Hollywood it turns over there's just no spark.
