Just discovered your channel, its great! I find it therapeutic to watch. I had a question, do you guys ever use honing plates?

@JAMSIONLINE 2 жыл бұрын

Yes, but it depends on a variety of factors. We don’t have them for every single engine. The plate for this engine is over $1000. For a stock rebuild, the benefits aren’t there. On the flip side, certain engines distort much worse than others, and even on stock rebuilds they MUST be honed with a plate.

Nice video as usual. I imagined that all these press fit stuff needed heat/cooling to actually go together. But just ”dry driving” is enough?

@mdbohica Жыл бұрын

Great work! Now I am not a machinist, so I have a question. When you reinstall the valves, I see you carefully put a tiny amount of assembly lube in the channel where the retainer sits. That seems unnecessarily tedious, why don't you just have a little cap full of lube, say .25" deep and just dip the end of the valve in?

@Joshhalley711 2 жыл бұрын

What kind of exhaust seats were those? They machined amazing! We typically use hardened SBI seats I believe they are a high chrome alloy and can be difficult to get a nice finish sometimes.

Where are you guys at? I wish you could have done my last build. I always built with reliability and some performance in mind. So far, I've never had one blow up on me. But I'm done building cars. My last build was a '79 AMC/AMX with a Chevy 355/350 with a R700 backing it up. Can you say "Make it fit"? Seemed like everything was custom from mounts to driveshaft but it worked.

7:02 if the valves are both closed then why would air leak past the stem? Am I missing something?

@2drewbaker 8 күн бұрын

He is testing the valves from the intake and exhaust port sides, under vacume. The valve stems ends are within that side of the valve sealing point. If they, some how, tested them from the combustion side of the valve, (under pressure), there would be no leakage issues of the stems.

You need to heat that head up before you press in anything. Once that engine gets hot, those seats can literally just pop out! Same with those guides, they can come out. Just ask dodge about dropped valve seats. Not a bad job at all, but you need to heat the head up before you press in anything.

@JAMSIONLINE 2 жыл бұрын

I can see you think you know what you’re talking about, but you don’t. Heating the head for the install has nothing to do with whether or not the seats and guides will stay put during normal operation.

@stevegarboden2437 2 жыл бұрын

Good seat run out is nice, but it's WAY! over rated, pull the vacuum with the head assembled, then torqued to the block with no valve train and you'll see that it went to hell, then finish assembly and run the engine, if you check the seat seal at that point the vacuum will be better than if you put grease on them the first time.
