RX7 allnight

i got a 1st gen awhile ago i thought i checked the tranny fluid but i was driving it the other day and i heard alot of noise and heat coming from the tranny so i thought it was low. took it home and for the life of me i cant get the 14mm bolt out. i sprayed some pp blaster on it yesterday iam about to go back out and check.. i might just need to get a tourch and heat it up for a second. any thoughts? and if the tranny was low or at out gear oil could it seize the tranny fill bolt?

actually i just think this is very common, if the tranny hasn't been messed with for a while, heat and build up just tends to lock bolts. Use PB blaster, or wd 40. spray it, let is soak for a while, see if that works.

damn, i read right over that lol...idk man, i've had a couple really stubborn ones, specially cars that have been driven where there's lots of salt on the roads. but usually just a few minutes soaking on pb blaster does the job . . .

14mm you say? Get a bigger wrench, or a breaker bar, or make a cheater bar I wouldn't worry about breaking something that big.

i made a cheater bar, didnt budge. i even layed underneath the car and used my leg as a cheater and nothing

get a long ratchet and hit the end of it with a hammer or something, that usually works for me lol. or get an air gun/drill/lazy man's screw driver. just trying to throw ideas out there man.

i always use a little heat on those. i fire up the map gas torch and heat the surrounding area to expand it. remember, you're dealing with aluminum so not too much heat in one spot for long. you'll get it free that way. the reason that they seize is because the trans is aluminum and the fill/check plug is steel. when the two metals are together, a small amount of oxidation can form from dissimilar metals.

^^ with regards to that, spray some wd-40 on it, then spray it, that way the oil burns off and warms up the metal, instead of applying straight heat to the metal....that's the way i've taken out a few other bolts, works great.

Skip the WD-40 and go straight to P B Blaster or if you feel spendy, buy some Kroil. Heat can also make the removal easier. Keep in mind that the threads have a slight taper to them, similiar to gas pipe fittings. This often leads to overtightening. When re-installing the plug use anti-sieze o the threads.

i used a pair of vise grips and got it off then replaced it with a regular 3/8ths drive plug. saves time.
