PCM Rebuild & Info

[Leedanger]

I'm about to rebuild an engine I have never rebuilt before and could use a little guidance. It's approximately an 1988... I didn't see any serial tags anywhere, but I did find the Ford block casting number on the starboard side under the block which reads " D9AE-6015-ED-1". Also the bolts to the mechanical fuel pump are horizontal, so I believe this to be the marinized 5.8L 351 Windsor.

I've rebuilt dozens of 5.7L 350's, but never one of these Fords. Is there a good manual in the iboats library that I can follow? The main topic I am looking for is timing (if setting valve lash is the same). For the GM's I run the crank around and look to see if number one valves move as it reaches TDC and if they don't I know that I am at TDC for #1, otherwise I am at #6....Do the same rules apply for the 351? I'm guessing not because I believe the firing order is completely different. Speaking of which is 1-3-7-2-6-5-4-8 the right firing order for this?

And lastly when it comes to getting parts I like to know what automotive applications I can use (generally speaking) in case I am in a pinch and can't find one...for example if I need a new oil pan gasket and I go to autozone and tell them an 88' Bronco with a 5.8L am I speaking of the same engine?

Thanks again as always....you guys are always here in a pinch.

D9AE

D= 1970 to 1979
9 = is the year 1979

if your engine is a standard turn your firing order is correct
Right hand turn you would move the 1 to the right of the 8 and read backwards 1-8-4 and so on.

Pan gaskets are the same as any 1979 351 w

You need to get a ford book. The cylinders are numbered different and the valve are just tightened all the way down.

If your boat is a right hand turn ( prop) lets us know. You will need a lot more info for a rebuild

Thanks Lyle,
So yes, it is standard rotation and that's great to know about the block serial number. I think I have an older ford book around I'll have to look. Meanwhile, am I correct also that the cylinders number 1-4 starting from the starboard side then 5-8 on port? Will both valves be closed @ TDC still?

Re: PCM Rebuild & Info

Your welcome. The engine is set up just like a chevy. On most of them if you numbered the cylinders the same way you would have the same firing order.

Forget all that. Yes 1234 is the starboard side. Remember that all manifolds has the standard firing order on them. some were grounds off for a RHT but not all. Finding TDC is the same as other engines. ( unless your RHT) No valve adjustment. Just follow book and tighten rocker all the way down. Yes both valves on 1 will be closed at TDC.

Re: PCM Rebuild & Info

Perfect thanks. I was looking for firing order on the manifold but never found it or it's one of the select few that don't have one idk. Regardless it is certainly LHT and I feel pretty certain based on the info you gave me and the book that I got all the square pegs in the square hole. Thanks again for your time.

Re: PCM Rebuild & Info

Just an FYI on Ford block numbers...
The actual block/part number it's self will give you the year the block was designed/revised, and what it was originally intended for. Like GM/Chevy they may have used the same numbers from year to year, so don't assume D9 automatically means it's from '79. If you look below the D9 series of numbers, you may see a 3-4 digit date code that should tell you the exact year it was cast.

Sorry if this is a hijack, but I was confused when seeing this thread. My background is Caterpillar and they number V engines from front to back, so you have odd numbered holes on one bank (side) and even number on the other like this:

Seems like others do the same, and there is no agreed way. I will definitely be confirming this when I am discussing V engines from now on. Prior to seeing this I assumed all were the way the image shows. What a potential mess :facepalm:

Sure would be nice if everything was the same, but they aren't. Here is an example.

Jeez. Worse than I thought. The firing order stuff doesn't bother me, but the cylinder numbering deal is way flipped up. "World! We need a meeting." :facepalm:

Weird that the Modern Hemi and Ford have two cylinders on same bank firing consecutively. Seems like it would vibrate like crazy. I guess it works or they wouldn't do it. All others always alternate banks. Hmmmm.

This has all been very helpful to me. Thanks

Re: PCM Rebuild & Info

I'm amazed that the old Ford flathead fires 1-5-8-6-3-3-7-2. Maybe #4 is a spare plug? :watermelon: I know, it's just a typo. It's 1-5-4-8-6-3-7-2.
