    Hey guys, me again. After I broke off that bolt (picture will be included) I seem to have some trouble getting the head separated from the block in the area where the bolt broke off. Everywhere else I have been able to get separation, but not that one spot. I’ve filled the hole with PB Blaster...

    So I’ve got a question. As I was pulling my head off, I came across a bolt that was rather stuck. I ended up breaking it, but as I pulled it out, I noticed it was dry and rusted, rather than covered in oil like the rest of the bolts I had pulled so far. I was wondering what this could be a sign...

    Right now I'm going though my engine and deleting anything that isn't needed. Just wondering what all I can get rid of and the car will run fine. I have the ERG and coolant stuff on the intake gone, heater core is gone, majority of the vacuum stuff is gone now. Just wondering what others are...

    Hey guys, I’m trying to pull the engine out of my ‘75 280 right now, and I cannot for the life of me get the engine and tranny separated. Does the crank have to be in a certain position? I am honestly completely lost, any input or help would be appreciated.

Does anyone have any links or know of any...

    So just cause my engine that I have is old and I’m gonna need to take it out anyway to work on it. I wanted to ask what engines would work in a z31. I’ve done a bit of research and I know a lot of people say just get another vg and drop it in but I kinda wanna keep my options more open then just...

    So I just very recently bought a 85 300zx and my whole plan is to put it all back together and get it running. It’s in pretty decent shape the engine is half taken apart because the owner before the guy I bought it from was working on it, said two cylinders were misfiring, but never said which...

    I'm looking to buy pistons and rings in +.40mm. Preferably in the flat top variation. There seems to be a worldwide shortage of some kind. Please point me in the direction of some +.40 flat tops for the l28. 280zx or 280z since they're the same block, just as long as its flat top. Thanks.
