Steve, if the block grew and added clearance between rear thrust and front thrust it would give opportunity for the crank to move further forward and in turn decrease clearance on the rear thrust.

[@theshed8802]

Just thinking Steve, as the block heats up, it will grow more in length than the crankshaft. As such the front thrust will be further away from the rear thrust than when it is cold. Haven't bothered to do any maths, but it should be possible to calculate without too much difficulty. Love your work. Regards Greg

[@chriswentworth7701]

Maybe the two different types of metal expanding at different rates of growth

[@OnEst_Opinion]

Was thinking the same thing when he discussed the seven thousandths tolerance on the crank last video. Like yeah she’s perfect now that it’s cooled all the way down and not under load or fresh off a run. Very surprised he didn’t seem to consider that when going thru everything.

[@philb5593]

Mullet’s engine has more clearance than any other SMX. If the block growing is causing problems here, it would be worse on all other engines.

[@sneezinhatch]

Actually the heat and pressure from the transmission drive line etc can create a larger gap for a minimal amount of time

[@gordonburnett9672]

If it's a compound issue, with heat, expansion rates and the pressure from the converter, added to maybe a little dynamic shortening from twisting the crank just slightly at peak torque, and some flex in the thrust bearing housing. It could be why it's tagging the bearing. Not knowing how much pressure the converter is applying and the amount of movement that much pressure causes in the crank, it's just a guess, but probably get a thou at most static, but add the twist and it might be enough.

[@rexschimmer7394]

Steve, a comment regarding the high pressure section of the oil pump. It appears that the pressure relief valve is of the "spool" type which are great at accurately modulating oil pressure but as you have found out they are very susceptible to contamination. As you said the high pressure pump gets it's oil from the oil tank so it is imperative that the oil in the tank be as clean as possible. That is only possible by insuring that all oil put into the tank, both the return from the scavenger sections of the pump, also from any new oil that is poured into the tank and by possible ingress of contamination through the tanks breather. The most important is the return from the engine through the scavenger sections. The best way to ensure that this oil is clean is to combine all of the sections into one return line to the tank and in that line install a large industrial filter that has a minimum 10 micron rating with "beta" rating of at least 100. Beta rating is a measure of filter efficiency at the filter's rated micron particle size. A Beta rating of 100 for a 10 micron filter means that the filters single pass efficiency is 99.99% efficient for removing 10 micron or larger particles. Use only filters that use fiberglass media, do not use automotive filters as they are almost all paper filters that are very inefficient and have high pressure drop.Use industrial filters made by Pall (the best), Hydac or Parker. Use a large filter, one that has a nominal flow rating of 100 gpm would be a minimum. The larger the filter, the slower the oil goes through the filter the better the filter works. These filters are not cheap, but neither is your engine! Also do not use screen filters, they are very high pressure drop for ratings in the 20 micron or lower also regardless of what the manufactures say, you can not clean them by back washing them with solvent. You would be amazed by the amount of contamination that is in "new" oil so it is good to pour new oil into the tank using some sort of filter and do not try to get every single drop out of the can as most of the contamination has settled to the bottom of the can or bottle and comes out with the last drop. Use some sort of good air filter on the tank breather to prevent ingestion of air born contamination as the tank breathes from the oil level fluctuating. Before retiring I was an application engineer for one the major industrial hydraulic pump manufactures and worked on hydraulic systems that ran at 5-6000 psi with flow rates of several hundred gallons per minute and on all of the systems the "return line" filter system was the key to clean system oil. As always I love your "lessons" and your open mindedness! Keep it up! Rex Schimmer

Steve, I love the through analysis when things go wrong. Most engine builders only show the good things on their engines. The scope of designing an entire engine to live in HP numbers such as these will always require a lot more inspection and maintenance than an off the shelf build. That's the only way to make them better. It would be interesting to set up the block and crank vertically in a press. Dial indicator on the front of the roller thrust housing, and push the crank down to deflect the front of the roller thrust .020, and see what amount of pressure it takes to do that. Although it would probably damage the roller thrust to test it this way.

Aluminium has a greater coefficient of expansion than steel. If your roller thrust bearing is at the front of the crank and the plain bearing thrust face is at the rear, then it is possible that the thrust clearance on the rear main tightens up as the block gets hot and expands more than the crank. Is it also possible that the crank compresses slightly under very high axial load induced by charge pressure? With that force being taken by the roller bearing at the front of the motor, this would also cause the clearance to close up on the rear main. Maybe the combination of these two factors and a bit of deflection on the roller bearing housing adds up to the 20 thou required for contact on the rear main. P.S: Love your in depth analysis of these things!

[@newhavenneil]

The elephant in the room - Cleet's oil tank. Maybe had a bit of crap in it.....

[@dennisisom4420]

Hey Steve, really like your channel and all the content. Just wondering have you checked to see if any of your welds have flaked off.

[@fluffpantss]

That's what I was wondering but wouldn't you see that on the suction side of the oil pump? The only other thing I could think of is the return lines from the turbos. Maybe the bushings could be failing.

[@Prolly_tyler]

I thought the same thing when i saw the welds

[@davidgardner4940]

I like how Steve will explain problems in plain English and actually show the difference between good and bad parts

[@screamn1979]

Steve thank you for posting these videos, I learn stuff lol.

[@jasoneperrell]

Your great at explaining things!!

[@CoyoteCrimeLord]

I found the problem too! It’s got an SMX big block in it! Things more reliable than this engine has been in Cleeter’s car: British electronics from the 60’s. 2 strokes with straight gas in them. Land Rovers. The weather man.

[@backroadboosters4017]

This guy holds great information and I'm so glad he's here to share.

[@804MRMAN]

*The choice of music 🎶 is so abnormal. 🤣 With that said, and I always say "You never really own a Steve Morris engine, you just use it"*

[@calebperham1969]

I love your videos and your work steve but in order for a converter to put pressure on the on the pump gears and housing causing pump failure as well if this is happening especially in a th400 you need to start with cooler flow there is nothing to limit charge pressure in this transmission most guys run a pop off to limit this I've had one of those fail and bite me once great stuff steve

[@alnix7250]

Great video as usual. I still did not see enough damage to account for the metal in the filter. Where does the return for the turbos dump. Didn't they replace a bad turbo. Must have been in the tank.

[@camperADK]

I'm glad you found the problem with the engine.

[@DriftJesus]

Love the honesty and transparency. As a team manager myself we run into these issues all the time. Its all easy in retrospect! Only additional thing possible would be to swap a spare pump in at the track and rule out a pump issue. Its not a ton of work to replace a dry sump pump and most guys with a 4k hp motor carry a spare :)

[@gmabailey40]

Still wasnt the issue. There was something putting excess pressure on the crank. Hopefully they find the issue in the trans.

[@DriftJesus]

@@gmabailey40 well, it was the idle oil pressure issue. Which ofcourse is scary because one would think the excess pressure on crank & oil pressure could be related

[@whatta7793]

Steve is a true master of engines. If it's to be known, this guy knows it, when it comes to an engine.

[@uncledglobal6779]

As a note on the thrust bearing, if you have a std thrust bearing on the rear on a roller thrust bearing on the front and the clearance is .027 for the regular thrust bearing on the back and .007 on the front, then you have .020 difference between the two. Since the block is aluminum and the crank is steel, they have different coefficients of expansion. Basically aluminum is double that of steel. Like with the rods. Looking at roughly 24 inches difference from the front to rear and a temp change from 80 degrees to 200 degrees, the crank grows by .019 but the block grows by .037. So that means the block is pushing the rear thrust backwards by .018. That eats up most of that .020 difference. So just a little converter balloon pushes the crank right into the rear thrust. Probably just add another .005 clearance on the rear and it will be fine.

[@newtonfirefly3584]

'Uncle Global', Your comment, attempted claims, clearly indicate You are NOT a proper engineer, mechanic, within proper knowledge of materials, mechanical, mechanism, which is applied correctly within the entire engine block, bearings, crankshaft, etc. YOur wording, incorrect, improper, invalid use of 'growing' to describe expansion alone is a clear indication with Your lacking of, with proper basic knowledge. Good Luck

[@johngoodman7160]

Diagnosis of everything is a must you have shown everything to look at

[@throttlebottle5906]

cannot say I've ever seen a crank walk backwards against and eat the forward side of a thrust bearing, except once, when a washer was placed onto the crank snout behind a journal, where it shouldn't have been! crank was pushed backwards and wedged hard against case front, it ate everything up quickly(accidental thrust location). lol add-on junk bolted to the crank snout/pulley could potentially push it backwards hard enough to cause damage, that would be some major oversight and bad assembly work to cause it though. watching the rest to see if anything is found.

[@burningbridges9127]

Thank you for taking time out of your busy day to explain this stuff to us. You're an amazingly smart person bro!!!

[@gtnoslp]

Give away Dyno shaft looks pretty hefty compared to that flange bearing that blew apart! ..... Vlog taken at Great Lakes shows extreme tolerances when the motor was hot and now cold, tolerances seem within standards. Heat might be the game changer.

[@TS50AU]

The roller thrust bearing is at the front, while the stock type one is at the rear, so as temperature goes up the block would grow more than the crank, DECREASING the thrust clearance. That combined with pressure from the converter... Probably none of this makes a difference when racing for 6 seconds, but on the street drive between tracks - and towing the trailer - the whole drive train would probably be warmer than any other time. Also, for the trash in the filter - Was the dry sump tank cleaned out? Trash could have come through from previous junk left in the tank???

[@Mattvardaman]

I swear KZbin plants the idea in people’s minds to say “check and make sure you’re subscribed. I’m hearing about people being unsubscribed.” Never once have I been unsubscribed unintentionally. It’s almost like they say: To get paid for videos this must be said at least twice.

[@zzzxxzzz3248]

Neglecting to lash down the valves caused problems. Cleetus was told to lash them but cleetus takes shortcuts .

[@colindonaghy8617]

Gday Steve, with that bypass being stuck, is there another way for the oil pressure to be relieved at high RPM? It looks like that pressure side pump has seen a little bit too much pressure. Hydraulic gear pumps eat their housings in exactly the same way when a relief valve is set incorrectly or fails. The scavenge side would not be damaged because there is no pressure there, but the pressure side would be damaged. The high pressure actually bends the shaft and pushes the lobes into the housing. Happens really easily on aluminium pumps.

[@cantstandya1983]

“So currently I’ve found one problem with this engine…it makes too much horsepower…. Steve Morris

[@bcbloc02]

Why not put the trust on the back of the block so it isn't trying to collapse your crank like an accordian under thrust load. There has to be close to .020" of collapse in the crank webbing under load for that back thrust to still be kissing or the retainer is pushing off that much likely a little of each. Regardless I think it would take a lot of stress off the crank and bearings if it only had the rotational loads to deal with.

[@garethhaywood4134]

Always good to see someone who really knows what there doing and you can learn from

[@connorlabelle]

Take a shot every time he says “that looks fine”🤣🤣 jk dope to see a intricate tear down of engines. You’re a beast of a man Steve🤘🏼🤘🏼🤘🏼

[@ultimatejay]

If I had low oil pressure issue with and external pump, the first thing I would check is the pump, before I tore down a complete engine. Also, the minor scuffing inside the pump doesnt seem to add up to all the metal in the filter.

[@racingdatasystems3708]

Sooo… a certain engine company with 3 letters in their name (they build 70% of the NASCAR engines) had issues with this style of bypass in the past (20+yrs ago) the solution was to sleeve the piston area. *Any debris in the alum wall would hang up the piston.

[@joshrawlings2621]

I recall Sam glaring at Cleetus when they installed the pump & filter & ran the unit. In a Somewhat dry state. A Dad like Face of disapproval by Sam…🤣

[@tonecold216]

The sped up tear down is therapeutic

[@todd3518]

that bypass being open explains a lot, he came in after the pass and said low oil pressure were done!!!!!

[@puggsincyberspace]

So the oil tank may have stuff in it, you should clean it and put a filter on it if you can...

[@johnnyrocko7105]

Something tells me Steve has enough small metal slivers in his fingers that metal detectors go off Reminds me of rebuilding hydraulic pumps when the rotating group explodes

[@Self.reliant]

I love it instead of just saying wasn't me you go through it and show this is an issue but really it's ok

[@scottphillips6259]

Cleetus needs to flush his oil lines and tank prior to engine reinstallation. Thanks Steve for the videos.

[@bullfrog1807]

“No wear nowhere” Sounds like a new t-shirt slogan haha

[@HoRRiiBLe1313]

9:20 dude said “actual horsepower”. Go big or go home brother! 😂

[@johnrodriguez473]

Cletus has a transmission problem, mainly his pump doesn't have a orifice installed in the converter feed passage and it's shoving the converter forward with at the pressure it makes available if he's running a TH400 or clone. Unfortunately it's showing up in your engine.

[@joebeasant5056]

CSI Steve Morris, great episode.

[@bio_stack]

Reduced thrust bearing clearance due to thermal expansion seems possible also, can you really know if the crankshaft or block heats up quicker? Also aluminum has double the expansion coefficient....

[@skullhart]

Expensive lesson here I'd bet. When you have a customer complaint you need all the information available. Maybe create a customer questionnaire before induction of the engine. I'd have certainly thought that checking that pressure relief valve would be on a "lessons learned" list.

[@slopoke22]

Steve, after 18 years ive found that there are a lot of dreamers out here! Everybody can build an engine as good you can or better, smh.

[@bartpang]

The block does grow .001 per inch for every 100 degree F. So it would be over close to allowing the thrust bearing to touch. With that being said, the bypass looks to be the main culprit.
