  1. Hey everyone, this is my first time posting here on the forums. I've poked around and read on here and a few other sites for a couple of years now and have finally gotten around to making an account. Majority of my problems I've been able to solve either by reading on here or in one of the manuals but I've come across a bit of problem. I own a 1981 280zx 2+2gl N/A 5spd, over this last weekend I started tearing the top end of my engine apart to have head work done. I have the car torn down at a friends house and his dad is really wanting the car gone so I need to hurry up, figure it out, and wrap it up, please help me! I have no prior experience with cars or mechanical work so this is all new to me and I'm still learning a lot, please forgive me for any ignorance or lack of knowledge/understanding, I really appreciate any and all of the help you guys have to offer and look forward to your recommendations and responses! I've gotten everything torn down to just the head now, my problem is I can't remove the head. It is sealed tight to the block. I've removed all 14 of the head studs and the 2 small front cover bolts. There is nothing that could be holding it on, I've given it a once over a million times and a half to make sure I wasn't missing something and throwing the towel in for nothing. The last head stud to come out broke in the block on the driver side in the middle of the engine, about a cm or so was left sticking above the thread. From what I've read this shouldn't stop the head from coming up and out so I'm under the impression there must be something creating a really tight seal on the head gasket. I'm guessing it's either rust and corrosion, fusion from overheating, or the K-Seal copper head gasket leak stop I had sadly used, probably the latter. So far I've tried wailing on all sides of it with a rubber mallet, pulling, pushing, and yanking with all my might stopping just before I give myself a hernia lol, and soaking all the edges and head stud holes in PB Blaster and WD-40 Penetrating Oil. I've read a number of articles so far recommending a variation of ideas and would really appreciate any and all of your guys input, advice, feedback, and help. Please share this with anyone you might know who can help. So far I've seen the following recommendations; use a few wood wedges in between the block and head to slowly and evenly pry the head off (what type of wood? how wide, tall, long, and thick? what degree of angle?), use a screwdriver and slide it in between the block and head to pry it off (could lead to potential head damage), use a 2x4 on the sides and hit it with a big ol' hammer, use a propane torch to heat up the area the broken stud is and also areas suspected of corrosion/fusion (could lead to warping or other problems if i'm not mistaken), use a long pry bar or pole in one of the intake runners on the head (could bend/damage the head because it's aluminum), stuff a bunch of rope into piston 1 and 6 then turn the engine over and use the cylinder head and rope to push the head off (I don't know the first thing about timing so this option makes me really nervous, I don't want to move the pistons without the cam sprocket and timing chain connected because I wouldn't know how to re time it or where to begin), use a high pressure compressor on the spark plug hole (I don't have access to a compressor), or use a engine hoist/lift attached to the head and bounce it tell the head comes off of the bottom end (I don't have a hoist/lift and have jack all for money so renting one isn't an option). A number of those ideas leave me very weary about the damages or problems that could follow and the other ones I feel incapable of acquiring/doing or simply feel it wont cut it, I will probably be trying a number of the above ideas anyways throughout the week and following weekend none the less. If any of you have recommendations, comments, or ideas please feel free to drop a reply, PM me, or shoot me an email, any and everything helps, I would really appreciate it, thanks guys! Also if any of you are in the San Diego area and open to giving a fellow z enthusiast a hand please let me know, I can buy you some beers and food for your time or whatever's clever. Again I can't express enough how much I appreciate any and all of your guys help, thanks in advance for your time and help! - Noah M (Word block dissected by Zed Head)
