freeze plugs

[70chevfred]

well i just bought a 01/72 fj40 and just rebuilt the f motor. my problem is the freeze plugs, i have already replaced the one on the back of the block twice and one on the side. its been a pain in the j**p . does anyone have any knowledge on keeping them in the block . i ve been slowly breaking in the motor to prevent any major problems but as soon as i took it for its first bath in the mud, it pop the rear plug out and i got it tow back to my shop. im trying to go to gorman next sunday so your help is greatly useful before i start to lower the motor and try again. thank you in advance.

where did you get your freeze plugs? i had my F rebuilt about 8 months ago and i had the same problem. the guy who rebuilt the motor got the plugs from a kit. needless to say, they leaked and popped out. i ended up ordering 3 new ones from toyota. they are more of a concave disc than a cup. they went in great, and they have not been a problem since. thanks

you were right the OEM ones were just a little bigger. we put them in today and look like they are holding. and the rear one it the biggest pain in the A**

One of the biggest fights I ever had with my old machine shop was in getting them to stop using aftermarket freeze plugs. For the last 10 years now, I just drop off a set of OE plugs with the motor, along with a 2 page list of protocols, to 'remind' them how I like to build a landcruiser engine. EVERY time they stray from the protocols, it costs THEM money.

OE plugs are the ONLY ANSWER.

Speaking my mind!
