Freeze plug or Expansion plug info

[tramp_drift240]

ive got two or three leaking freeze plugs on my kade, i plan on diving in soon to replace all of them at once.

what im needing to know is how many there are, and what size plugs they are.

also, id like to have people's input on whether i should go for regular metal tap-in freeze plugs, or if i should just get some of those washer-rubber-and nut freeze plugs that you tighten with a ratchet to squeeze it in the block.

so, maybe a link to the FSM, or maybe just some nice info. and people's opinions about metal vs rubber expansion plugs.

please and thank you

i found a link through google for a 1993 240 fsm, but i couldnt find any kind of specification for the freeze plugs.

i have to try to change them pretty soon, im moving to another state in 2 weeks and im hoping to use the trip to break in the rebuilt engine.

so, freeze plug dimensions anyone? opinions on metal vs. rubber freeze plugs?

just call up your nissan parts dealer and order stock replacements...

if the KA has as many as an SR does, it should take 6 to redo the block. Including the back of the block inside the trans bellhousing.

so, if i recall from rebuilding it, there are the two on the exhaust side of the block, three on the intake side, and one on the back.

any opinion on rubber vs. metal? the rubber one i may be leaning toward, i used one to replace a metal one that kept busting out of a 1971 dodge 318.

thats why im trying to get the size of the plug, so i can see how much the rubber ones are. theyre a lot less likely to leak, dont corrode/rust, and a lot easier to take out/put in/replace than the regular metal tap-in ones.

The only reason I have ever had to replace nissan freeze plugs is due to fire damage. I have wrenched on a ton of nissan motors and have never seen bad freeze plugs.

I have used 3 typesbronze (the best but hard to install and find)metal (will rust like the OEM ones)Rubber (easiest to install BUT can become loose , also expensive)
