Ok I'll put some brake cleaner on a rag and clean up the area around where the gasket seals. The spark plugs are Autolite, he also replaced the distributor most likely with the cheapest one he could get at the local parts store, but I'm not sure.

 

Not to interrupt your sequence of repairs, but at some point, check those plug wires also and see if he replaced them as he probably should have and regap the plugs @0.044 or change them if needed.

 

Ok will do, he did say he replaced the wires too. He went through repairing a bunch of ignition/spark related parts because I guess he couldn't get it to start for about a month and finally he replaced the computer and that fixed it. However, when I drove the truck back to my house, it stalled while idling in my driveway the next morning and I never messed with it after that. I just went straight into fixing the oil leaks so that will probably be something I'll have to check out once I replace these gaskets

 

I wouldn't personally be able to clean just what's under the pushrod cover. I can't help but imagine what else is that dirty inside the engine, and before I know it I'm rebuilding the whole motor.

 

There are a lot of different PCM's. There is a calibration code on your driver door or door cab body. You can check that and pull the PCM and check the number and see if he put some random PCM in from a JY.

@ andym Look at his original picture on post one.

 

I don't see a picture in post #1?

 

Yeah your right, that's pretty much how I feel, I'll just do a quick clean and hope for the best. The pictures pretty much start on page 2, I'll be posting a lot of pictures for the oil pan gasket haha I'm sure that's going to be quite the task

 

Good idea. I'll check that out

 

This is what the engine looked like when I first got the truck last week

 

It was pretty dirty

 

Sorry andym that was another engine on another post. It left a lasting memory.

 

Brake cleaner took some paint off so I lightly sprayed the cover with some high temp paint, obviously not the best paint job, but it will do for me

 

Is it normal that some of the little circle pushrod gasket/seals sit flush and some are popped out a little bit? Here's a pic, those 2 don't sit level and the others sit level or below level, also you can see the last spark plug that is all carboned up compared to the one next to it

 

Does the inside of the spark plug wire for that plug have carbon build up? If so maybe it is arcing

 

The lifter top appears to be protruding for the #5 cylinder and then as you make your way down to #6 cylinder the lifter is retracting into the bore.

From the look of the spark plug on #6, are you sure it's just not the manufacturing process used at the time, color could just be different month or so, an older plug in inventory.

When you examined the plugs, are they all Autolite plugs, same #?

The PO may have just thrown in some old/new plugs from sitting on the shelf for 5 years.
