    The saga of getting a drama free start on Patch...

    I'm with Will. I'd start with a compression test and then I would look at injection timing. White smoke tells me either not enough heat or injected too late. I suppose it is possible that all the injectors could be screwed up if the pump was passing junk at some point. Of course if the pump...

    I agree. The fact that the precup skirts hang down so far and are not heatsinked directly. Combined with the apparent slow transmission of heat from the inconel. The only part that still bothers me is that they let combustion gasses go around the skirt where those gasses will heatsink to the...

    Aye. That's what they told me the profile was for. Consider yourself updated. Now that this thread has been totally thrashed and pointless I need to delete 90% of it or start over. Just saying this off topic stuff is polluting. My rants included.

    Appreciate it and just an fyi I was not pointing at you directly. You have already helped me out in very real ways beyond advice.

    What was the question? Do you remember? All I got was a bunch of opinions with thinly veiled bashing and contempt from people I had respected. None of my questions was ever answered. I am almost 50 and have been fixing engines of one form or another since I was 10 and my father first taught me...

    Got my heads back. Thinking of finishing them up with some gold plating. I'll be spending more time modifying some precups now that 8 thou turned them a little proud. I'll not be explaining the hows and whys as I feel it just promotes superiority complexes and attitude. I'll post updates with...

    Isuzu 4BD2T diesel swap into Suburban

    If I had a dollar for every tool I "repurposed" I could retire. Well maybe not but you know what I mean. I have so many welded bits of doodads here and there I have forgotten for what purpose some of them are for. One of my favorites was some little cheapo side cutters I modified to get inner...

    I traded both my kids to the machinist so that isn't a problem. lol Thanks for reminding me I need to pay him again. Glad I haven't kept track of the costs. Probably be about 13k by now. If you start doing coatings you will know what I mean by time. First cleaning, masking, sandblasting, then...

    Lol. I can't even find the comment. I went back through every post. Only took I could find that you made was that one for dimpling round tube to hold the hose on. I have been tired though so ignore that post. :sorry:

    The thing with coatings is the time involved, prep mostly. I have 30k on a v7 out there. farm truck around town mostly. It needs pulled (collapsed piston skirt I think)and if I find it is a 599 block I will probably bare minimum rebuild a 6.2 I have laying around here for it. As for the heads...

    I think most people know that the cup only contacts the head on the side and bottom of the top outer lip. But then I thought most people knew surface temperatures of something heatsinked and cooled with water don't get much higher then the water temp. Depending on the rate of heat travel of...

    :( no video....... Totally bumbed. I am always making my own tools. I love to see tools other people make.

    I coated my precups but my objective is or was to insulate the heated air from the block. My thinking was to keep the precup heatsinked to minimize cracking on it. I see a problem with trying to insulate the precup from the block. Doing that is going to allow the precup temps to go really high...

    well to make the precups flush after a shave they machine out the relief. If they machine too far then they really screwed it up. Of course if they machined with the cups in then that wouldn't be the case. Some machine shops will do it without and some will do it with. because the cups can move...

    Actually I am looking into it. The head has been shaved before so not sure how much more they can shave. The shop that did the work is 60 miles away through downtown Portland. Pain to get to. I'm thinking maybe a local shop could shave just a little more. I need to measure all of them and see...

    Ok I found some bare heads on amazon. BUT I am suspicious they are any good. https://www.amazon.com/dp/B0176LF0PK/?tag=jhdiesel-20 What do you guys think?

    Hot diggity! Steve at Harland Sharp sent me new 1:6 rockers next day. I am stoked now. Except for that head issue I'd be confident again.

    provent 200 instead of cdr?

    I was always led to believe it was to keep a slight vacuum in the crankcase to keep oil from leaking past seals. I can see how that might be bad if you were fording deep streams.

    I am not sure the actual depth Thickness of a piece of paper or two. The danger with machining with the precups in is catching them in the bit and tearing things up since they can move. Now I have had other machinist say they know about that problem but still do it after pining the cup in...

    They machined the recess too deep. Then they red threadlocker on the precups to hold them up in place. They provided some precups but I had my own I wanted to use. That is how I found out what they did. Precups are in contact with the head in two places. The main heat sink area is the sides of...
