Thoughts on this, possible freeze plug repair (1 Viewer)

[fj40z]

I just picked up a used 1FZ that I know absolutely nothing about. I found this on the rear passenger side freeze plug. Kinda looks like some sort of plug or patch but have never seen anything like it before.

Installed by machine shop.

When I had my 2F head done, they put something very similar at the back plug of the head.

Where did you find that block Stephen? Michigan?

Haha!! No, Raleigh! It's a complete motor with all accessories and ecu. I got it just for the cylinder head as my plans are to still get a short block from you sir.

@beno was it a patch or just something they put on to identify their work?

Where did you find that block Stephen? AT THE BOTTOM OF LAKE Michigan?

FIFY

For the record I did go to Michigan over 10 years ago and hauled back this rust bucket. It started this whole crazy addiction

Warranty plug. If you're an idiot and overheat the motor it melts off and they void the warranty on the rebuild.

Addictions typically lead to records.

Sweet 40! Makes me miss my Freeborn...

If it makes you feel any better, here is my free 1FZ-FE that I got...

Yup, it's a solder plug with a pre-determined melt point. I've used those hundreds of times when I was rebuilding engines and it was cheap insurance against claims. Once you show a customer the melted away center, after all their bitching and whining, they tend to calm down and realize it might have been something they did...like forgetting to fill the coolant system before driving it. Happened a few times...idiots.

In other words, likely a rebuilt motor.

If anyone knows overheating, it's @NLXTACY!!

Also found what looks to be a Toyota parts sticker on the back of the head
