Fixing The 235 Chevy Head That STUCK A Valve Guide!

[@JAMSIONLINE]

Make sure you head over to the new @SBIVavletrain KZbin Channel! www.youtube.com/@SBIValvetrain We've been using their parts in our shop for decades! Really appreciate them supporting us all these years!

[@NICK-uy3nl]

Do you ever cool the valve seats (and valve guides) in dry ice to make it easier to press them in ?

[@JohnH20111]

High Quality parts and Service

[@shadowopsairman1583]

​@@NICK-uy3nlyou can maybe icebox them

Your old man is so humble I love how he focuses on everything the previous machine shop did well instead of crucifying them. Y'all are a class act and you're lucky you get to call him "Dad"! love the content.

The best thing to me is not only the positive relationship they have, but that dad is open to learning from son as well as the other way round. It is how all good teaching/learning situations are, we work together. Incredible content, wonderfully relaxed, and lovely genuine people. Thank you from Down Under.

[@tedsteiner]

You have such a wonderful relationship with your father, it's such wholesome content honestly. The level of knowledge and raw experience he has just shines in these vids.

[@sc5015]

Worked in a trade over 20 years. When you spend that much time, if you're good at what you do, you pick up little sensory cues of something going wrong before most people would ever think there was problem. 14:43 , your father knew right away the tone change of the driver on the vale seat was wrong with the impact driver. He didn't force the issue, moved on to the next one for the time being. Its those fine little things I love seeing in all these videos I watch, a testament to how much experience your father has, how his primary senses of touch, hear, and feel is better than any manual in print or tool made to do it better. If anyone sees and appreciates the same, the crank grinding vids are a masterpiece of pure sensory operation while simply watching a simple dial on the machine.

[@donaldpereira2652]

I've seen a few of your videos about the venerable 235...I had one when I was 12 years old, in a 53 Belair convertible...early 53, with poured rod bearings...my Dad and I rebuilt that engine in the backyard, on sheets of plywood. We cut up beer cans for main bearing shims. Wound up rebuilding and installing a 56 235.

[@19MarcoPolo71]

There’s only one thing I dislike about all your videos and that would be when they end. Can’t wait to see this ol’ 235 fully assembled 👍🏻👍🏻

[@ElvinLeadfoot]

Yes Jim:) Every time we watch your channel… We learn something. Especially the crank grinder:) When you put stop bolt in between the crank weights. How flexible a Big Cummins Crank. Jim - you can also straighten a crank if it’s bent. They jack it in the bent spot. Use a soft race driver and hammer .. Give it a wack about the fillet section:) V - Blocks hold the crank on each end. Then you hack on the low spot Sometimes it has to be repeated 2 or 3 times After it’s within .001 or .002 Put it in your grinder and start grinding

[@shawnwalsh5430]

Wow I have learned so much and I am 73 year old retired technician for Ford and Chevrolet. That was one fine looking 235 Chev head and I have seen several of them. I used to drive a 74 Corvette 80 miles some days to pick up parts on emergency jobs. All the other technicians would complain because they didn’t get to do it but I could do it on my lunch time. It had the 300 hp 327 cui engine and it was smelling like burnt paint and hot brake pads when I got back. It would cruse at 100 mph and do 140 mph on I 70 in the Missouri River bottom interstate. No State Patrolman could catch me. It stuck like glue on the secondary curved roads.

We also oven clean all of our iron components, if a head has removable guides we always remove them before putting them in the oven, most often simplifying the extraction process.

We generally do as well; however, in this instance we debated not replacing all of the guides. Once it was cleaned & we checked a bit closer we decided to go ahead and replace them all!

[@leonhart2452]

I never heard of crosshatching the valve but I have knurled and reamed guides to get them back in spec. I do believe that the knurling if done properly and after reaming the flattened point of the knurling supports the valve stem but there are small dimples between these flattened points that can hold a bit of oil. Kinda like a ball bearing in each dimple.

[@zakburnett6690]

You should consider using a like light oil to spray in till it stalls if you can't run it awhile I've had good luck with it with small engines it's a little extra work to start them again but it's almost always just crank a bunch and clean the plugs

[@alro2434]

Why does it NEED to be started? If it's just to idle it for a half hour, you're doing nothing, in fact more harm then good!

[@zakburnett6690]

@@alro2434 I've seen alot of stuff rust up because the oil falls off like the cylinder walls and the cam lobes when it sits for a long time it's mostly fine in a climate control storage but most garages or just outside it'll act as a heatsink so it'll be cold in the warmer day and collect moisture in alot of places maybe not in a desert but definitely where I live. Sure starting it will cause some ware but it'll recover everything in oil, it's best to drive them even a little your right it's good for the rest of the drivetrain too

[@cdabg]

I read somewhere that knurling the valve stem is a "quick" way of tightening up excessive clearance in the guides without replacing them since knurling the stem increases the diameter. You have an awesome channel here loaded with the "right way" of doing things --- very enjoyable!

[@georgebettiol8338]

I agree - that's my understanding of why valve stems are knurled. In the case of the previous machinist it made a the already 'tight' valve guide situation even worse.

[@joshh6470]

Back in the day when I worked in a machine shop (talking over 30 years ago, late 80s when I was a pimply faced teenager) we put those type of seals on everything including the Chevy inlines, small blocks, big blocks, Ford, Chrysler, didn't matter, they all got them. Most in the 40s-70s came with umbrella seals and I think the small block 350s even into the 80s. I can't recall ever having a comeback based on those valve stem seals. I pivoted to tech in the 90s and don't regret it, but I do miss working on engines every day sometimes. Good times with good guys.

One of the most interesting engines I ever rebuilt was in a 1939 Chevy pickup. It was an original 216 with oil dippers on the rods and 5 piston rings on the pistons; 3 rings above the wrist pin and 2 oil control rings below it. I was surprised at how smooth and quiet it ran when I got through with it.

My dad owns a scrap yard, so I get to rummage through the baubles. I have the drivetrain out of a 1956 Bel Air that was rotted away. I believe it is a Chevy 265 with a steel powerglide behind it. Not sure what I'll do with it, but I love keeping some of the old tech around instead of seeing it shredded.

[@tonysabatino4725]

Rebuilt a head for a DT 466 years ago which had been previously rebuilt not too long before. The exhaust guides were history and filling the crankcase with combustion gasses. I noticed positive seals had been placed on all guides. I deemed that the problem. Got new parts from IH. They handed me the same guide seals. I told them that was the problem as to why the engine is back apart. They called the old mechanic over from the back of the shop and he said “hell no you don’t use those on the exhaust guides.” He went to the parts bin and got what had been used previously. Reworked the head and as far as I know the engine is still going about 15 years later.

[@PaulBrown-zp3uy]

59 yrs ago did my first “rebuild”. What I did not know vastly exceeded my knowledge. How I wish I had an opportunity to work in your environment. As an auto shop owner attending a business management seminar we were asked what about our business gave us pleasure. All others said money but my reply was, hearing the engine fire up after major repairs. My reputation is excellent but I still feel there is so much I don’t know. My only question is did you not trust the valve guides. When I used to try to air hammer in (or out) VW valve guides the heads sometimes cracked. Of course I did not have a good mentor nor means to check my work. Keep up the great work and share the ketchup. Are they a sponsor ?
