Cleaning up a milkshake-what to do?

[runnerC2]

Well I should be getting my 4runner out of the shop soon- hopefully within the next couple of days. Long story short I bought it with a blown head gasket not knowing much about the 3.0 and older yotas in general (except that I love them). My bro and I tried to fix it. Got it back together and it wouldn't run. Got tired of it and took it to the shop and my mechanic has it running again. I can't believe I have had the thing for 2 months and haven't even got to drive it yet!! :gun6:

Anyway, once I get it back how do I go about cleaning all the coolant/oil mixture out of the crank case? I was reading a thread on yotatech about seafoam and was wondering if putting some seafoam in there would help. I have put fresh oil in it so I figured I would change the oil and see how that looks. Then maybe change it again after a short time. Any suggestions?

Nothing? Nobody has ever had to clean up after a blown HG? I find that hard to believe...:hello:

When I blew out the head gasket on my '86 and had milky oil I junked it. No help, sorry.

Sounds like you have the right idea. After mine blew and I repaired it, it took two or three changes if I remember correctly. Seafoam really can't hurt either. Just have to get that stuff out of there. Also don't forget if you are running a mechanical oil pressure gauge to clean or replace that line. Good luck man.

 

[runnerC2]

Thanks. I hadn't even thought about that line.

I have heard of people poring diesel or kerosene through the block but I personally wouldn't bother. I just change out the oil if it looks like it still has water mixed in..

Changing the oil several times in a very short period of time would be the best place to start. Maybe with some kind of oil additive.

Just hope it wasn't driven much after it happened, crank bearings don't like coolant.

It wasn't driven much. Hydrolocked the motor and the starter would grab. We pull started it just to get it on the trailer but it was only running for maybe 30 seconds.

I would change the oil at least until you check the oil & it looks like all the coolant/water is out of it. The problem with getting the coolant/water in the oil is that it causes oil to oxidize & become acidic. The acidic particles can become inbedded in the boundry additives meant to attach to the metal surface for start up lubrication.If the acids are not removed from the metal surfaces in the oil they can slowly eat away at the metal. It would not hurt to use Seafoam or similar product meant to clean sludge,varnish and other contaminents off the metal surfaces.
