Doing a rebuild and look what I found.
So I'm doing the engine teardown and I come across this. Does anyone know how this happened? I know is something with the oil, but is the oil injector bad? And how do I fix it so it won't happen again.
Thanks

ROFL looks like someone pooped in your coolant passages. I typically have those plugs blocked with pineapples seals. But looks like there is some corrosion happening probably due to worn water seals or not changing out the coolant when you need to. If the coolants been sitting for a long time that enough to make the color of the anti-freeze brown but that build up looks like more neglect than just sitting. But a good cleaning will fix that when you do a rebuild.

that's "mud"
i've seen it in every engine i've torn down that's over 10 years old. pretty sure it's a biproduct from the engine using both aluminum and iron components.
that spot doesn't have a lot of coolant flow, so the deposits have a place to settle.
more frequent coolant changes can prevent it.

looks like someone tried to block it by filling it with silicone...? check the texture. that will help out...
people usually plugs those anyways. cheap and easy way is a quarter with some high temp silicone. i done it that way on every motor i have had. never had a leak or a problem.

What has happened is the previous owners of that engine didn't use the right coolant and probably never drained and cleaned the water out of the engine periodically. So corrosion occured and ended up in the *dead end* passages of the engine. Not desireable. Think Rust.
The rear side housing has freeze plugs in it and are used for what you mentioned (keeping the engine from cracking if not enough antifreeze is used in freezing weather. The front side housing might have them also but..........I forget.
