How much would this cost? I have the same issue

What causes the pin to break ? The cam towers no aligned ?too much stress from the springs ? My L20 Datsun broke in trying to see if it’s my cam set up or what

Rip John. Sure miss watching you demonstrate your skills.

👍complimenti

3800 series II have 1.80" Intake and 1.52 exhaust. Can the Rover use them?

👍👍

nice video, you still need to keep veryfing the washers every 40k miles or so? for wear?

I have a late 70’s 302 block, I’ve been thinking about building 347 stroker. I was just wondering about the pros and cons of it?

For us non machinists interested in machining and Porsches, how is the set up determined? ie how do you insure it comes out in the correct place of the combustion chamber with the correct angle?

RIP, John. I'm honored I had the opportunity to meet you, tour your facility and see your work. It was awesome. I wish I had gotten the chance to have you work on a motor for me. Godspeed, sir.

What kind of grinding wheel do you put on your machine?

Interesting vid. Guessing that's a EL (61") knucklehead cylinder by lack of oil holes. The missing thing here is TORQUE PLATES. Even a cast iron cylinder, and especially one being blown out for a sleeve, needs that simulated stress that only torque plates (I even install the exact head and base gaskets to be used). This opinion will undoubtedly have mostly dissenters, but most people simply don't HAVE torque plates, or don't want to take the time to deal with them. In his defense, it'll probably be ok in a EL. This guy is providing a valuable service here for folks like us who actually RIDE our old bikes. We're stuck using old, reworked junk like this, while hundreds and hundreds, if not thousands of pristine vintage cylinders languish away in boxes and milk crates, put there by hoarders, looking to build that old bike up day, only to have their grandkids eventually toss the parts, ignorant of the treasure they are holding.

Just pull the rope seal out and install a two piece seal from Best seals. Done

Would be nice to see the job completed

Is it possible to not take that second cut all the way down and shorten the sleeve accordingly. This creates A step and would prevent the sleeve from moving down. So interference fit and step Value your opinion thxx

Speed and feed both seem excessive. I think these engines started life as a van engine, Bedford CF. I worked on one JH which had snapped its cam belt, and worked at a Chrysler/Talbot dealer in the UK when the Lotus Sunbeam was current.

There is a second oil hole to the push rods, it has a plug in it. You remove adjustment screw to drill through. Was there some reason why this was not shown?

So you drill down into the water jacket? And then just thread locker? No thread sealant?

Good 👍👍👍

Ok

no cutting fluid?

How did it work?

Very cool!!

What information does this rig provide?

Who came up with the name

Wouldn't it be better to place the block in an oven to heat expand before sleeve insertion? By hammering don't you risk damaging the sleeve coating and therefor risk long-term galvanic corrosion?

genaue Bezeichnug des Webers lautet DCNVH ...diese sind u.a im Maserati Bi Turbo Vergaserversion verbaut. Sehr ähnlich dem DCNF. Je nach dem welche Größe Übergangsbohrungen dieser hat, kann nur der 18, od 25 od 24 sein. Guter Job John

Jo El . Do you know where one can buy one of these Porta tools?

This one setup looks more like my situation, but there ain't no technical trouble shooting that can not be fixed,...I own happy hands..haha

I don't understand why you made rough cuts for finish? Why not write it or move the block so your boring bar is only 0.200 above the part before starting the cut? It looked like a third or more of cut time was spent dropping on the Y axis at cut speed just to start each cut. Cutting plunge speed? If you want the tightest possible fit by hand, wouldn't it work better to travel at 1/4 the speed or even less? Leaving it rough will need a bigger hole for it to fit. A super slow cut and a shiny surface could be smaller and still fit nicely. My preference is a slight interference fit. Warm the block up to 80/90 degrees and sleeves in the freezer. Not a great difference but should slide in and out freely at this temperature. Locking in a second or two after placing it. Torque plate and finish hone liners, especially nicasil lined aluminum.

Done sir jo el

Could you use a fixed diameter reamer to open out the bushes after installing? Thanks.

can this be done to 230 250 292 inlines?

Я думал сначала греют сам блок, и максимум охлаждают гильзы в азоте, потом вставляют без проблем?! Какая технология лучше?

Bana hornama makinesi lazım yardımcı olursanız sevinirim motosiklet için

Kolay gelsin bereketli olsun inşallah kardeşim

Very cool

So nice Please send me you're email or website Thanks Maher

Do this adapter still available?

good thing the 456 is outta warranty by 25 years now, thats very upsetting, so many possible catastrophic failures just waiting.

is this necessary for a 4.00 stroke?

I have my 235 in machine shop as this is written. what was the final bore demention? Or how much press did you allow?

Awesome work. How did you manage to get the higher stroke with the same crankshaft? Kind regards.

Why didn’t you freeze them before battering them in? All it does is induce stresses into the liner.

Super. Can you upload a video on rocker arm shaft rebuild?

Fella, that turned out HORRIBLE! Deleting this video is your Best move.

He was one of the greatest of all time, really miss his videos. Thanks for the good conversations John. I’ll miss you

Over a million videos and noone yet to explain why none of these rods has oil holes like the factory. Most people are going to say you don't need it. Sorry my block don't have oil squirter
