Intake off and looking at a lot of carbon in the gallery. The carbon is coming from the heat riser outlets. Over the years they have heated the oil on the underside of the outlets to the point of forming carbon bits. Must have done damage to the old oil pump I’m thinking.
Handy little tool I picked up years ago from Princess Auto. It’s a series of tubes that attach to the shop vac. The tubes can be added or removed so you can get the right size to get in tight spots. This is working great to remove the carbon from the lifter valley and also in the heads.
Scraping away bits of the old intake gasket from the heads using a razor blade paint scraper tool. Very little engine sludge in the heads or valley surprisingly.
Timing cover off and the timing gear also looks a bit oil starved.
From what I read a .030 hole drilled in the oil gallery plug at the top (above the two lower plugs) provides extra oil to the timing gear. I’ll do that. The high volume oil pump should handle that OK. I’ve used a high volume pump on a high mileage Chryco 360 and it increased oil pressure overall over 5 lbs.
I’ve scraped away all the old gasket and then sanded the timing cover seal surface and water pump mounts with 150 grit to remove any leftover gasket material or corrosion. The pan is still in place
Pan off and the internals look nice with high mileage wear showing. Not a problem as long as it will start well, run smooth and not smoke!
Ditto cleaning the old gasket from the block. The rear seal surface was a bit of problem, but dental scrapers helped get all the old rubber out.
Not too much crud in the pan, but there was some of that carbon in the bottom that was washed down from the lifter gallery.
A paint remover wheel is doing a fine job clearing out all the old gasket material from the pan and the timing cover.
Next: Getting ready for paint.
