    So I recently bought this Flatty.
    I opened it up yesterday, didnt see any cracks. Not looking for a full rebuild but to freshen it up, clean and drive.
    What do you guys think?

    looks like one burned valve at least, can't see cracks in it, but it is pretty dirty still.

    Hot tank, and crack check the block, check the bore and get your wallet out..... If the bores are good and theres no cracks should be straightforward.... Put GOOD pumps on it from speedway or skip...
    My old engine looked worse and after the tank we found out the jackets were cracked...
    What year is the engine?

    clean it up, throw a good oil pump in it, throw on some aluminum head and a manifold and drive it.

    Taking it to get hot tanked and fluxed on Thursday.
    Hoping for no cracks.
    So if there are no "major" cracks, then oil pump, new water pumps, a dizzy, seals, carb rebuild,
    anything else?

    Your doing this without a disassembly??

    You might as well rebuild since your engine must be disassembled to get a proper cleaning and magnafluxed. You cant see cracks on a block that has components in it!

    Honestly, I've never seen an untouched flathead that DIDN'T look like that in the lifter valley when I removed the intake. Non-detergent oil, a substandard filtering system, and running too cool for it's own good most of the time equals black puddin'.

    Yeah at this time a full rebuild is out of the question.

    Is there anyone in the Orange County, Ca area that would be willing to take a look at it in person?

    How do you hot tank it without disassembly? And if it did get all clean inside those bearings, what prevents them burning up when it is spun the first time again?

    You need to take it all the way down to clean, then if all is OK, you can reassemble with new lube and seals at the very least.

    Pull the pan and check the pan rails where it bolts up. I've seen a few that cracked between the bolt holes and can run up inside the crankcase. The crack was hidden by the pan until it was removed. If the block is cracked there it is a boat anchor.

    The only reason I was saying that, was I called a local machinist and talked to him about what was going on, he said "no problem, you can leave everything in it"
    So I will for sure not go to him.
    I can rebuild a VW engine with my eyes closed, I am having a hard time with this. thanks for all the insight.

    Can't see burned valves from the pics, unless I'm missing what others can see. Do the valves look ok close up? I'd be more concerned about bore and piston wear. I can clearly see the top rings down the sides of the pistons. Man that thing is WORN! I had one similar to that in my 40, and while it did run, it was really fumey and smoked from the breather.
    That motor has a lot of miles on it, and while it could probably be run, (assuming not cracked) it wont run great because of the wear.

    It's not a boat anchor, but is probably past it's best for running like it is.

    You'd probably have done better to have left it in one piece, and just run it in blind ignorance. Now you've seen the wear and gunge buildup it will put you off running it.

    Lastly, the amount of wear and crud in it is exactly the amount it had the last time it was running. It doesn't wear out or crud up by standing.

    So the question is, how well did it run the last time it was running???

    If you can't afford to rebuild it, and want to run it then fair do's, just go for it. You can't really do it much harm. But you would only be able to sort of cruise around - it won't take kindly to wide open running and high revs, because chances are the bottom end is as worn as the top.

    Clean the oil galley tube properly with a rifle bore cleaning brush. This means taking the plugs out of each end and driving out the fuel pump pushrod bushing. You wouldn't believe the crap that can hide in there.
