In this video I am boring a few engines and filming the Willys F 134 Engine. All engines will get the same care as this one and I am going into detail on the piston fitting again. A few people wanted to see hand fitting the pistons again so here are the steps I take to get a perfect fit.
This engine came in at .010" oversize and I am using Silv-O-Lite pistons.
Engine was bored, then honed, then a plateau brush was used in each cylinder, and finally the crosshatch was obtained with a ball hone, which was a fine 400 grit.

Have you ever tried relieving an F head around the exhaust valve like you do on the L head and did it help power output? Just curious.

@metalshaperJeep 3 месяца назад

No, the F head has large intake valves in the head and much more power than the L head engine. I don't ever relieve F heads, only L head engines.

I worked at a dealership garage in the 1980’s and 1990’s and a lot of the new 4.0 six cylinders had piston rattle. Also many of the new Cadillacs had loud rattle on start up. The warranty claims all called it “normal” and rejected except for one man that lawyered up. He got a brand new complete engine “fresh” off the factory line that I installed. They sent it “plug and play” with everything on it including sensors, plug wires, manifold and fuel injectors, oil pan, pulleys, flywheel, the whole nine. Ha, ha! It was three times worse than the original engine. GM bought the car back and the dealer refunded his deal.

Even the large auto companies can't get it right some of the time. I hand fit each piston carefully and when my engine goes to the other side of the USA or overseas, I don't have any worries about problems.

Hello Brian, I have emailed you hoping to get some engine work done. I understand you are busy, just hoping to make contact with you. And hoping my email didn’t go to the spam folder. Please let me know the best way to contact you if my email has not made it to you. Thank you for your time

@metalshaperJeep Год назад

didn't receive and email from you.

@aussiedazvk4djh889 Год назад

Better than new Brian. 👍

@metalshaperJeep Год назад

Exactly. I like my engines to run and give good service for another 60 or 70 years.

Nice video Brian! What would be the maximum that the cylinders can be bored to before one needs to start sleeving it? I am not at this stage of my rebuild but will soon be getting there

@metalshaperJeep Год назад

early blocks about .040" oversize. Late blocks I have bored to .080" but sometimes I go thru the cylinder wall when going that large. Seems that each block is different due to the quality of the inside of the bore. If the coolant wasn't correct the inside of the block can become rusty and make the cylinder wall thinner. I am working on a block right now that is .060" over and I am starting to break thru the cylinder so I will have to sleeve it.

@metalshaper Thanks Brian, really appreciate the feedback. Completed my transfer and transmission cases rebuild, and all went well, thanks to your videos! Will be using your engine rebuilding videos extensively as it must be the best and most informative videos out there!

@skylinefever Год назад

Yes, this is why some machinists have a sonic testing tool so they know exactly how much material they have left.

Looking good there bud! What rings do you like? Silvolite pistons are real good in my opinion also, but I mostly work on large diesels so OEM is the way to go. Aftermarket is junk for the most part in my world. Cheers!

@metalshaperJeep Год назад

I usually use Sealed Power or Hastings rings, they seem to be the best out there at this time. I do understand about aftermarket JUNK and see it all the time

Have you ever used Rebuilder's Choice performance coated pistons?

@metalshaperJeep Год назад

@@skylinefever I don't use any type of coated pistons. Too many problems with them in the past and lots of information out there about their limited longevity.

@skylinefever Год назад

@@metalshaperJeep Thanks. I found it interesting to see a kind of modern engine tech in old engines, but wasn't sure it it would work.

@KlausSlembek Год назад

nice work. your attention to detail is rare these days

@metalshaperJeep Год назад

thanks for watching

@davewallen2678 Год назад

Brian, love your engine rebuild videos. I have a 1948 CJ2A w an L134 in need of rebuild/sleeve. Curious where you are located and approximate cost. Thx

@metalshaperJeep Год назад

I am located in Connecticut but work on projects from around the world. You can bring or ship anything that needs repair.

@davewallen2678 Год назад

Outstanding! What’s the best way to contact you to discuss scope and timing?

@garyrobertson3645 Год назад

👍👍👍

@rickdeyoung8886 Год назад

I enjoy hearing how you set things up it’s good to know that your knowledge is being recorded for future generations to learn from

@tomrichardson2099 Год назад

Brian, I always learn something when I watch your vids. Thanks for showing how engine building should be done.

@michaeldulaney2497 Год назад

You do real nice work Brian. I like your boring bar. Thanks for the video.

@scottosborne9604 Год назад

Looking Good Brian 💪

@TheOldaz1 Год назад

Nice work. When you set up your boring machine, do you set the postion by the existing "good" part of the bore, or???

@metalshaperJeep Год назад

I set the boring bar up by sending it to the very bottom of the bore. Unless there was a catastrophic failure the bottom of the bore usually has zero wear and is where the bar gets set up.

@RADIOACTIVEMASCULINITY Год назад

Love seeing these engines getting new life!

@metalshaperJeep Год назад

I enjoy working on them as well. Hoping one day someone sees these engines coming together and decides to become the next generation of craftsmen.

I like seeing people go to as little oversize as possible. I am so used to seeing people go to +.030 on everything, even if +.020 is readily available. Have you ever encountered Rebuilder's Choice performance coated pistons? I think it's fascinating to see performance coated pistons on stock rebuilds that predate performance coated pistons. I enjoy watching engine rebuilds on the Jamsi Channel. However, I don't think he ever rebuilt an early Jeep. 11:18 That's fascinating to me. I'm used to seeing the piston manufacturer call for a certain piston to wall clearance, and telling the machinist to measure at a certain part of the skirt. Doesn't that still ensure a proper piston to wall clearance and account for manufacturing variances? 14:57 It is my understanding that in the 1990s, every new engine received a plateau hone. Rebuilding a modern engine without one is not possible from what I have heard. 17:37 It's great to see a ball hone actually get used for the intended purpose. I am so sick of people just doing a quick re-ring with a ball hone, and not measuring how much bore wear they have beforehand. I don't know how many people I have met who bought a used car that said "Has a rebuilt engine." In reality, someone just pulled the heads, pulled the oil plan, used a ball hone, and put on standard rings. Those cars burn oil like crazy.
