3406E liner bore corrosion

From what I see of the pics I thank that is all above the sealing area anyway. My concern would be messing up the seals getting past the rough areas. One of the products you mentioned should be fine in my opinion.
That is just to make a smooth transition to the sealing area. No stones because you want all the original material you have left.

 

Like boxcar said. Looks like that's above the sealing surface. Take some Emory cloth and clean them up so no sharp edges and you should be fine.

It started leaking because the Orings were old and brittle. .

I've seen more engines get inframed from this issue then being wore out.

Time is a killer just as much as milage.

 

I have had good results applying a layer of JB weld to this area. Make sure you use the regular and not the quick and let it cure overnight. Flapwheel or hand sand the bore to remove the excess and to make it smooth. The big thing here is that the o rings dont get caught or cut on that lip when installing the liner.

 

have your block counter bored $100.- whatever the mobile guy charges.
measure your clean holes get shim packs and new liner's.

have you a professional straight edge (machinst grade) check you deck for warp and your head as well. spend a buck clean and save the block.

 

I have heard of and used Belzona.
Back in about 1984 i worked at a shop and we had a 300 Mack with a cracked block sleeve leaking coolant in to the oil.
The Belzona rep had us drill a hole on each end of the crack and then grind a small vee in to the crack itself.
We then filled it with Belzona and then pressed the dry sleeve in.
That truck never leaked a drop of coolant after that.
As you can tell from my story Belzona has been around a long time and has proven itself many times over the years.

 

use plenty of rubber lube on bottom seals and press constant when installing don't bounce them in. leave the liners next to the suspect seal areas out so you can watch the seals as they go over the rough area.
ideally you would have them machined and inserted.
you could also use an IPD crevice seal liner. the top square seal would cover, fill and still seal a poor surface.
otherwise worst case clean up surface and use belzona

 

Do it now or be down again SOON. I understand money is tight. So why waste what you already have invested.

 

Yeah what he said^^^ do counterbore cut and have a new counter bore insert put in. Kill two birds with one stone. Fixes the corrosion and levels up your liner or liners. The best way is to pull block and have a good machine shop repair it.
