gunk under intake manifold

The gunk you see is the lack of oil changes by the previous owner, and a lot of stop and go driving where the engine never got warm and stayed warm for a while. What to do now.........?? Choices range from nothing to complete rebuild, how much money do you wish to spend?

I'm gonna catch flack over most of this......so be it

Nothing would be new intake gaskets, bolt down the intake, put the engine into the car and start an aggressive routine of oil and filter changes and a quart of Risoline at each change, hot oil can remove alot of that.

OR, get 5 gallons of kerosene, scrape what you can out, with the pan still on wash down the valley with kero, you'll find the block eventually.

OR, very carefully take the engine appart, leave the rings on the pistons, mark them (the pistons) for what cylinder they came out of, keep the cam and lifters in order, keep the bearings in order, take the block to the car wash, blast the living day lights out of it, wash down all the parts in solvent, put the engine back together.

OR, do a complete rebuild to what level you desire.
