Oil galley head plug

You guys are great!

Gentleman,
I want to send a big thank you to all who have posted information about this topic here on the forums!

Several weeks ago I was driving to work, pulled into the parking garage, went inside and started going about my daily chores. Around 30 minutes after arriving at work one of the property maintancemen came up to me and told me that my FJ60 was leaking oil, and it appeared that I had been for a while as there was a trail throughout the whole property that led to my car!!!

I headed over to the Cruiser and looked around, sure enough, something had caused a leak, I thought it was a loose or bad line. I had some tools, new hoses, hose clamps and oil delivered to me and began to fix the problem. Once completed I fired it up and discovered this leak right near the #5 plug.

I called my shop and explained the problem, they said they would take a look at it, then I called the tow truck. While waiting I decided to do some research here and found this thread. I then called my father in law, showed him the threads. He said "we can fix it"! WooHoo!! I then called the shop and the tow truck and cancelled my "reservations".

After looking at the threads my Father in law followed everyones advice and my 60 is running again! Total out of pocket expense on this fix was probably 25.00!!!

Many thanks to all here...I want to make a motion that we sticky this thread for the FJ60 FAQ's this could save Cruiser owners lots and lots of money!

Thanks again all!
Rob

90% of all the factory plugs fail after a machine shop vat clean... its common practice to replace them as part of the rebuild... you wouldn't want that plug coming lose on a fresh motor and spoil the good feeling........drill and tap and a plug is the only way to be secure.......

X2.............never knew it was there until I had it strain relieved, painted and back on the motor. Then it started to weep. Evidently I missed the" ... its common practice to replace them as part of the rebuild... " part

I just saw this, let me put my $.02 in, I use a 5/16" x 24 tap, no drilling required, then I install 2 allen head plugs one deep, and lock it in place with a second. Red loctite on both.
I have done at least 30 heads like this, SOP on all my head work or overhauls...........

I've been carrying this secret for a while. Glad to see someone man up and tell it. I didn't use a F drill bit for the tap. I just was really carefull not to overstress my tap and went slow. But I figured if I did a writeup on it and didn't tell people to use a drill bit someone would snap a tap off in there and well we know what would happen. That would suck.

I like the two allen head screw idea. Will be storing that little nugget away in my brain.

Well, you all officially scared the bejesus out of me. Here in Ecuador it’s not an easy task finding plugs, so I opted for a different approach. I also did not like the idea of “possibly” breaking a tap off inside the head. So until it’s time for a rebuild..... I do believe, as long as it’s not weeping oil and annoying me, I’ll never have a problem with this fix.

I’d like to see it try and pop out now.

Clever!
