Oil Cooler Housing Failure

[silverhorse]

While in the process of rebuilding my motor, I started to clean the Oil Cooler housing. (Blown Head gasket or so I thought) It had a very corroded area at one end. I started scraping with a small flathead. I noticed the aluminum was very soft so naturally I kept picking at it and this is the end result....

I assume others have had this issue, How do we prevent this from happening in the future???

Less than 150,000 on the motor, BTW.

I wonder if something like this may help......

"Colonoscopy"??

ROFL I just noticed that in the pic, GOOD EYE!

Yep, I have Colitis, or did. I had my Colon removed a couple years ago. My doctor likes to go in , Literally and take a peak around ever few years ...... I hope I just didn't open a can of worms with this..

Glad you're now healthy.

So, do you suspect the problem was the oil cooler all along, rather than the HG?

just keep up with your antifreeze regiment.

As others have mentioned, maintaining the cooling system will avoid this in the future.

I'm not sure what the PO did as far as maintenance.

Wow, Looks like you win the most damage award! I plan to run the Toyota antifreeze, hopefully that will take care of it.

I would get a couple bottles of Prestone Super Flush and run that with distilled water for a week or so. Then, flush and fill with Toyota Red. I was surprised how much crap came out of mine when I did that.

Thanks for the tip!

Thank you, sir!

I noticed to HG looked good when I tore the motor down so this probably was the problem all along....
