What have you done to your Land Cruiser this week?

[cims1970fj40]

Started my 40 today to make sure she’s running properly before converting to a sniper only to find out that I have antifreeze leaking underneath my bell housing.
This makes me sick to my stomach.

There's a 50mm core plug on the back of the block. I'm trying to remember if it's behind the flywheel.

Lord I hope not because I don’t want to have to pull the transmission

Pulling the transmission/t-case combo isn’t that much of a thing if the plug is really the issue.
easily done in a few hours if not doing a bunch of “while you’re in there”.

Do you have any other thoughts where it might be coming from?

Given the close proximity of the firewall mounted heater control valve and the drip you see, check this “warm pull” action to double check…I discovered a slow but steady drip when that valve was in the closed position on my 40. It did not drip when I pulled that knob for heat…but, it was summer so I Replaced that valve easily

I checked everywhere else and the surrounding area of the flywheel cover doesn’t have anything running on either side of it.
I wiped the flywheel cover where its dripping from and once I finished wiping it started dripping again.

Of course you checked the base of the head at the rear, right? Can you pressurize the cooling system and see anything more pronounced?

I looked for a second but need to look again. I’m currently cooking so going to head back out shortly

That’s for the insight. I did look in that area earlier and it looked dry but can try that.

You can get a loan a tool pressure tester at the local box a/p store. Remove the inspection cover and take a look.

Yeah I was planning on removing it.

UV dye in the coolant might help. With the light and a mirror or perhaps a cheap borescope that plugs into your phone.
You could look between the fire wall and the engine.
Dye $10 uv flashlight $10 scope $10 on ebay

Thanks! I have a borescope that I’m plan on using. Need to get the dye

That is an oil galley Welch plug that goes bad on the rear of the block

Bounced around in Sedona yesterday.

 

[Oregon FJ40]

Made brake lines for the first time. Hopefully they survive the leak test.

I took the transmission down. I forgot/didn’t understood change the input axle seal when everything was open. That chinese cheap motocross bike lift was a big help. So tight to get off, maybe easier with the bellhousing? 3B and H41 here.

 

[Rochfort]

A little before and after is always nice. This came out way better than expected.

We drove to a waterfall just outside of Bogota. Lots of twisties , turns, low and high elevation. The Land Cruiser ran flawlessly. We had a great lunch (menu del dia) at a roadside restaurant. The weather held up well, as we were expected to get rain.
