    Block deck surface

    Ok, I'm all in. I wanted to rebuild this engine anyway, so I may as well do it now. This is a project for me to learn and have fun with, and it's not like I need it to take me to work on Monday. Speaking of learning, all of the guides I've seen to pulling the engine have you attach the engine hoist to the cylinder head. Seeing as I've already removed the head, is there a recommended place on the block to attach to? I'd rather not put my newly rebuild head onto the scummy block just to pull it off again. Also, any thoughts on Tom Monroe's method of pulling the engine without the transmission? I've heard that one is pretty controversial.

    Block deck surface

    Thanks @Lazeum - that's the way I'm leaning. My impatient side really wants drive this car asap, but I think I'll feel better if I clean everything up first. As long as I have this engine out I may as well strip and repaint the engine bay. As long as I'm doing that I may as well strip and repaint the rest of the body. As long as I'm doing that, I should probably clean up and repaint the frame. As long as I'm doing that.... oh no, here we go!

    Block deck surface

    I just pulled the head off of my new (to me) L24 that hasn't run in ~10 years to get it rebuilt and resurfaced yesterday, and my engine looks like it's in worse shape than I was hoping. When I pulled the head off, there was coolant puddled in some of the cylinders. I was hoping to just get the head work done, pop it back on and be able to drive the car around for a few months. After cleaning up the deck surface a little bit, I've found that it's pretty scratched up and has a few nicks and dings around the top of the cylinder. I was planning on pulling the block apart at some point so I can get it hot tanked, but now I'm worried that I need to get the deck resurfaced before I can run the engine. Am I being too conservative here, or do I really need to pull this thing apart and get it re-machined? Coolant in cylinders right after pulling head off: Nicks and scratches on deck near cylinder: More scratches: State of cylinder before minor clean up:
  4. Aha, that makes perfect sense. Thanks David and Miles! A friend printed out a FSM (the one here) for me as a gift and that hot air intake diagram isn't in it. Miles - which FSM did you pull that image from? It looks like my flexible tube deteriorated long ago. I'll reinstall the intake and hunt around for a replacement tube at some point.
  5. I'm currently pulling the manifolds off of my 1971 240Z, and I can't figure out what this pipe is that's bolted onto my exhaust manifold. It looks totally vestigial because there is no opening for it on the manifold side, and the other side just dangles into the engine bay. What is this thing, and can I leave it off when I put everything back together?

    Broken Fuel Pump Bolt

    Yeah, I believe it. I'm a little scared to try welding for the first time a few mm from that machined surface though. Maybe I'm being too timid and should just give it a try, but I'm worried about splattering metal and having to pay to get the pump mount resurfaced. Great tip about agreeing on a price with a machine shop beforehand, any idea what a decent rate for something like this would be?

    Broken Fuel Pump Bolt

    Ok, so just a quick update - so far nothing I've tried has had any success. Last weekend I tried JB-Welding a nut onto the stub after roughing it up a little with a file and cleaning it off with acetone. I used the two-part stuff instead of the SteelStick because it claims a higher strength. After letting that cure for two days I put a wrench to it, and it just broke off immediately. I then tried filing some flats onto the stub and turning it with an adjustable crescent wrench, but it just rounded off my flats. I also tried vise-grips and channel locks (even squeezing the hell out of my channel locks with another pair of channel locks) with no luck. That bolt is seriously stuck in there. I've been hosing it down with PB Blaster every morning before I head out to work, but I don't think it's making a difference. Finally, on the advice of a friend I bought a left-handed die and managed to get a few threads onto the stub last night. It's in pretty bad shape now after all of the abuse and I didn't want to take too much more material off, so I just did what I could and applied some red Loctite to a left-handed nut which is curing on there now. I'll try turning it tonight and see what happens, but given how stubborn it's been so far I have low expectations. At this point, I'm fine with just bringing in a professional to help me out. I did some searching online and came across this guy who does house calls, so I'll give him a call and see what he charges. I'm also fine just removing the whole head and bringing it out to a machine shop. Does anyone have a shop they recommend in the LA / Sherman Oaks / Van Nuys area?

    Broken Fuel Pump Bolt

    So... A friend of mine loaned me one of these gadgets claiming he had gotten out plenty of stuck bolts with it. Well, all it managed to do was turn my bolt into a peg (see attached depressing photo). The nut still kind of threads onto it so I applied some J-B Weld 2-part KwikWeld to the inside of a nut and it's curing onto the peg now (with plenty of Saran Wrap between it and the block). I'm going to let it set overnight and see if I can get it out tomorrow. Thanks for all of the help everyone, I'll let you all know how it goes. @manimal : How did you know what size bolt it is? I checked the FSM as well as my Haynes manual, and none of them specify any of the bolt sizes. Do you have another book you pulled the info from, or did you just know it off-hand? I'd love to be able to look this kind of stuff up in the future.
  9. I'm trying to get my new Series 1 240Z project car started, and it looks like the original fuel pump isn't working. I bought a replacement, but the bottom bolt snapped in half while I was removing the original. Now I have half of that bolt stuck in my block with no good way to pull it out. Does anyone out there have any good ideas? I've heard of people welding on nuts, but I've never welded in my life so I'm a little worried about trying it. Also, I'd like to get a replacement bolt for when I eventually pull that sucker out. Does anyone know what size bolt this is?
