Hear something knocking in your engine? Afraid it might be rod knock? Here's how to check it out.
Whether it's a knocking noise inside your engine or a clicking one or whatever else, the only truly foolproof way of checking for rod knock is taking a direct look at your rods and rod bearings. To do that you need to remove your oil pan.
Removing the oil pan is easy. In the case of my MR2 mk1 all you need to do is get the exhaust out of the way and unbolt the oil pan. After that remove the oil strainer and you can take a look at your rods and rod bearings.
Shake the rods a bit. If they feel loose that is very bad and everything needs to come out. In my case the rods were rock solid but once I removed my bearings I noticed some very alarming things and confirmed that my engine unfortunately did develop rod knock. I just got caught it pretty early. Rod 1 looked best, rod 4 worst, to me it seems like it's an oiling issue, although my oil pressure was good the needle on the manual oil pressure gauge was pretty bouncy.
So what now? Another rebuild. I'll drop this engine soon and get it fixed using a junkyard 4age engine I just got. Time to get dirty again.

[@garylangley4502]

I had a '66 Jeep Wagoneer with an AMC 327 V8 engine. It ran quiet, but smoked some. I was going to replace the rings, but when I removed the rod bearing caps, I saw that the bearings were worn down to the copper. I checked the journals with a micrometer, and they were in surprisingly good condition. I replaced the rod and main bearings, along with the rings, and a few other things, and it ran great. All I'm saying is that I'd check the crank first. You may be able to polish the crank in the engine and use a slight oversized bearing, and get a good engine.

[@802Garage]

No no no you use a inch-lb torque wrench you're second uses a ft- lb torque, well maybe in you're next life "engine failure".

[@markgunther2502]

I spun a rod bearing and the conrod had elongated into an oval on my turbo engine. With the engine in the car and without removing the crank, I was able to sand down the main and rod journals, and change all the main and rod bearings. Obviously the damage was much worse than yours. I debated buying a new conrod but didn't want to have to remove the entire top end to pull the pistons so I decided to shim the conrod cap with a piece of soda can (just a shim on the bottom not the top) and used standard size bearings everywhere including that one conrod. I had debated whether to use one standard and one +1 oversize bearing on that one conrod but I'm glad I used the shim now. I checked all clearances with plastigauge. It runs great has good oil pressure (70 cold and 35 hot). I babied the car for the first couple hundred miles, changed the oil and since then have been driving it hard as normal. It's been about 6 months since the repair and runs great. All that to say, don't give up you can fix these type of problems without rebuilding the entire engine.

[@paradoxdea]

2:46...Smelling your bolt is very important when it comes to changing oul.

[@timdegroot4159]

Actually, I would replace the crankshaft, because I saw heat damage from the friction, meaning that the crankshaft probably has lost some hardness at the journals. However, getting a junkyard engine is probably cheaper, so repearong this one, and getting a junkyard engine if this one fails is also a good option

[@CodewortSchinken]

Online diagnosis is always difficult an d more like poking in the dark, than serious problem solving. Plus, I know Volkswagen EA827s but not Toyota A-engines. Like you said in the video, the damage can be caused by a weak oil supply, due to a worn out pump, bad/wrong filter, or dirt inside the oil galleries. Do you flushed and brushed the galleries, when you rebiult the engine? The rod bearings get less oil than the mains, so they die first on not enougth oil or low pressure. Dirt inside the galleries first goes into the main bearings and grindes them before the rod bearings. Unplausible according to the footage, but i woul check them. You will have to pull the crank out anyway. Different Idea: Of course the crankshaft could have been already damaged or bent when you assambled the motor. Do you checkt it for balance and messured the exact journal diameter? And what size of bearings do you used? Maybe the journals were already grinded once before and standard sized bearings caused way to much bearing play --> more oil loss at the bearings --> less oil pressure + big bearing play -----> damaged bearings. Used Parts are cheap an especially on old cars the only available ones. But you never know, what happend to the stuff before. Little tip at the end: Put some cardbord on the floor, when you work under the car. It´s way more easy to slide around on it and less cold in winter.

[@FairwayJack]

polish the crank and install new bearings

[@fflynnful]

Should the replacement bearings be the next size down?

[@chriscusick6890]

Depends on bearing clearance ascertained by plastigauge or micrometer.

[@chriscusick6890]

You could but risk excessive clearance thus lower oil pressure. Engine should be thoroughly cleaned of all metallic particles before new bearings are installed.

[@notanotherrcchannel]

Thanks for the detailed look inside! I"m having some heavy knock in my '85 MR2. I haven't cracked it open yet but it shows all the signs of bottom-end bearing failure. I've juiced it with 20w-50 and we'll see how it goes a few miles at a time. I plan on a swap or rebuild. Look forward to more of your videos, and hope to have a few of my own up soon. Take care!

[@d4a]

+bee dee Sorry to hear you got the knocky rods too. 20w50 won't help much or for long. I would suggest getting the engine out asap, before it throws a rod and makes a huge mess of your engine bay. That would also mean you will need a new block. If you're determined to do a swap than it matters less, but still best to get it out soon. I'll be uploading an engine drop video next week, should be useful for you. Good luck and let us know once you upload your vids, I would love to see them. Thanks for watching.

[@roadworthy6901]

I feel for you brother! That's just the nature of cars, I wish you the best on the guts transplant and would highly advise a quality oil pump over something like a turbo, keep your chin up bro!

[@d4a]

Hey there. Thank you for your support man! I bought a brand new AISIN oil pump the first time I was doing this rebuild. I will see if it can be reused, it only did like 600 miles. But I will buy a new one if there's any hint of something wrong with this one.

[@BWeezy-sw1wy]

[@adbc6740]

Pfft copper being scraped away, that's nothing, i didn't even have a bearing left in my car, and i could grab fistfulls of metal shavings from the oil pan, and BAM!! I put on new connecting rod bearings, AND Voila! Runs like new😁👌

[@chriscusick6890]

Obviously he polished the crank journals. Also one needs to flush engine to extract as much metal debris as possible from oil passages.

[@dominiciacino4627]

The crank journals need to me measured and tested very very precisely. I'd say while you have it out, test the runout on the crank, taper and out of round on the crank and rod journals, and basically see if your crankshaft is worth a shit before you move on. Also, plastigauge the journals just to make sure that you have good oil clearances. Great build though, I just subbed to your channel about a month ago and love the content

[@d4a]

Dominic Iacino Thanks, will measure everything as I did first time. The problem turned out to be blasting media that got inside the engine somehow. I made a small update video about it. My crank is in the machine shop already, getting ground 0.25 mm. :)

[@wesleyedwards2764]

My first car was an '86 MR2. There are currently 4 mk1s sitting in my dad's yard. Working underneath was always a pain. I pulled the fuel pump one time and socked myself in the eye with the drill battery. Knocked it off a jack and onto a wheel I had slid under it while changing out the alternator. I quit for the day after that happened. Just about pooped my pants. Timing belt? OMG what a pain. I pulled the engine and transmission when I was 19 and had the block and head work done by a shop for $900. I reinstalled it myself. Priming the coolant in Mister two is a real PITA. The 4AGE is a real fun motor to rev though. They used it in the Toyota Atlantic series back in the day. Putting it in the MR2 was brilliant, but also a mechanic's nightmare. Toyota at the time was way more practical than fun and the AE86, MR2, and supra were big shifts for Toyota in the 1980s.

[@d4a]

You're a proper adub veteran my man! Much love for that. You're right, the space in that engine bay can be tight but it's still an absolute joy and breeze compared to newer cars.

[@tomg6284]

Use emery cloth and polish the journals then roll in a new set of bearings. Do this to big deisel engines and works every time.

[@darrynleslielees1111]

First seconds of the video, I thought the solution to all 4 rods knocking was to just turn the radio up. To be fair, that did work when I had rod knock

[@jamest.5001]

Keep a knocking, but you can't come in! Rod: what you mean, I'm trying to get out!

[@genegeneish]

I worked at an engine re-man facility and i did the crankshaft recondition and set up in block. Bottom end work should be done with the engine out of car. IF you really know your work and its an easy engine to access, a bottom end refresh is possible. I would not recommend this for a shade tree tech. The total run out on a v8 crank is .0002. The taper on a rod journal can be as tight as .000015. There is no mention of a crank knock ( crank main journal moving in a main bearing) which is not common, but happens, and it sounds like a rod knock and many times it is acceptable and doesn't affect engine life.

[@clayreal]

[@joshcallaghan9432]

[@donalddemsko6147]

You should of used plastigage to check clearence between new bearing and crankshaft. Should be somewhere around .002 In. Or slightly less. If needed, use oversize bearing to compensate. Make it a little on the tight side, so bearing can wear in. This may keep you from replacing crank or engine. Check other bearings.

[@rlarson3232]

My god that was funny, I needed that right now, the end of your video is how I feel right now, i just spent $1,100 on OEM parts timing chain, gaskets, oil pump and oil pan gasket, 16 lifters and the hours to install them. The knocking got even worse, the bad thing was I could not get the oil pan off to look at the rod bearings. I really do think it's probably rod knock, so I'm going out tomorrow to buy a car for the wife spending $11,000 to $17,000 on a car and park this pig 2001 Dodge Dakota with 200k mileage and figure what I'm going to do, I was thinking of buying a used engine $800 to $1,500 and swapping out the parts witch would put me at $1,800 -$2,500. not sure if that's the right decision the problem with that is I can by a long block for $2,800 and have a 3 year warranty on the engine. Sometimes its best not to be handy, in retrospect I should have parked the truck, bought a another car and pulled the engine I would have saved my self $1,1000 and 15-25 hours. This truck turned into a money pit.

[@d4a]

Naaaah. I thought that way for a few days after it happened to me to. I wanted to burn the car down. But the learning experience was valuable. I did the rebuild twice as fast the second time around :) Try to be positive about it, in the long run it will all make sense. Right now just park it and let things settle in your head :) The right decision will come by itself.

[@fasillimerick7394]

I've seen people laugh when they see a rod poking out from the block. Everyone knows it's now a boat anchor, and the owner was almost proud of the carnage. But when people hear that knocking sound, a pall falls over the group and no one wants to be the one to say it first. The optimist will always say, "maybe it's a collapsed lifter", even knowing it's a solid lifter engine.

[@nopochoclos]

Great video!! im doing the same with my CItroen 3cv (Argentine version of 2cv6) when i see the rock knock... is only the half the other parts in the bottom of the engine block... the engine was running fine ...is a 1974 model... never open the engine... very good quality engine ......

So your bearings went bad after a rebuild?, it would be interesting to know why they had deteriorated so quickly. Good video, thanks for sharing

[@d4a]

A bit of blasting media was left inside the block and it ruined the oil pump and bearings. A blasted block can't be cleaned as the blasting media embeds itself in the metal and comes loose only whem the engine heats up. Now I know better.

always check water and oil channels before assembly. Use compressed air and something like cable ties to check for cloth or anything in the way. Also its always good idea to port the cranks oil feed lines. Do some research on this topic for the next build. My 4AGE was running redline drifting 5 years, it broke its diff and transmission and it didn't give in :)

[@d4a]

Asen Moskov I researched a lot. You would not believe how much I cleaned all the water and oil channels. The bearings are usually the last thing to go on a 4age. I'm now suspecting my oil cooler because I didn't clean it. In any case, I'm the only one to blame here. I'll know the reason soon enough. Im removing the engine as I'm typing this :).

[@assko11]

search all oil related parts for clues, drain the filter in a cup and check with magnet. This is not normal wearing on 4AGE bearings. And i watched your build, the engine was built properly.

[@d4a]

[@JeffReeves]

Oh, and I forgot to mention. I think you have already planned this, but it should be relatively easy and cheap(ish) to take the crankshaft out of the junkyard motor you got and use that to replace your existing crankshaft (assuming it's out of spec and/or bent). Just need to get it machined to the right size and slap some new bearings in. Also, I laughed at the seppuku with the torque wrench. There's a bit of a language joke over here, where someone says, "I guess I'll just have to commit sudoku..." instead of seppuku.

[@Peelenga]

[@westmonroejoe6097]

There should have been metal shavings in the oil. That would have given u a clue. The best way iv seen to determine rod knock is take out the sparkplugs rotate one cylinder at a time to just past TDC then with a screwdriver in the sparkplug hole push down listen and feel for movement.

[@Jbuddaho]

I just bought a remanufactured engine then spent 1200 getting heads replaced (engine warranty only covers some of the labor cost) but they sent out new heads 2 weeks to get done just to find out my mechanic was wrong it wasn't the top end knocking it was the rod bearing

[@Jakebrakeweav]

Very good video

[@markherring3513]

The rods should have zero movement correct? I haver a bad bearing and I can wiggly the piston rod, from the bottom, back and forth 1/16" to 1/8"....this means I have a bad bearing on that piston, correct?

[@patjohnson3024]

Brilliant vid this stuff happens to me specially the exuast in the hoodie keep the faith man

[@1575murray]

When the bearings are worn this badly it is usually due to some type of abuse (running the engine low on oil or going too long between oil and filter changes causing excessive wear). I don't think normal wear will go all the way through the bearing material exposing the brass underneath it unless the engine has 150k+ miles on it. This engine probably has a lot of wear on the rest of its moving parts as well as the bearings and replacement with a good used or remanufactured engine might be the most efficient way to restore the car to good working order.

[@outtakontroll3334]

he says in a comment reply there was blasting media left in the block when it was rebuilt, which cause the wear

[@LukeplaysTV]

LMAO the ending of this video made me laugh so hard thanks bro

[@kananiedwin]

I think I know where you went wrong. First off sorry about your problem. I had something similar. I know how it feels but we learn from our mistakes and get better at doing such stuff. Now the problem might be you did not lube the bearings and the shafts. Its like this; any time you have metal to metal contact there's gonna be friction. In this case you might think it has sufficient lube from oil pan thus not taking the extra step of greasing the bearing. So when you start your engine it takes a few engine revolutions before the oil starts to circulate to the bearings, and those few seconds are known to cause damages similar to what you have. Solution: apply high temp. Grease aka engine bearing grease between the bearings and the shaft. Lots of grease this is a must do type of step in all kinds of bearings. Especially in cam shafts and crank shaft it lubes and acts as a spacer avoiding metal to metal contact before the oil circulates and takes over the spacing.

[@magnusatheos7301]

I would have liked to have heard how bad the knock was at that stage of bearing failure.

[@derwissenskiosk8041]

Could your hear the knock before you took a look at the bearings? And if so, was it a constant sound or was it hust now and than noteable?

[@d4a]

I could definitely hear it, but only once the engine warmed up. It was constant and would of course increase in speed together with rpm.

[@LukeTheJoker]

[@scottwheaton9689]

That crank isn’t that bad. I polished cranks worn like this with chrocus cloth & installed new rod bearings which good results. But that as long as the main bearings are not in worse shape then rod bearings were.

[@HT-wi2su]

This is perfect! im thinking of buying the same generation mr2 and the one im looking at has rod knock. Thanks!

[@Milkmans_Son]

You did the honorable thing.

[@j-deezy321]

My man said you can see the copper been scraped away LOL

DRY START 1. Rebuilt/Overhaul - Starting the engine without priming the oil pump to build up oil pressure. 2. Oil & Filter change- Starting the engine without waiting for oil to drain in the pan. 3. Oil Filter - using oil filter without anti-drainback valve

[@zuranku]

Is there a trick when putting the rod bearings back on?

[@johnfranklin5277]

How many miles on original engine when pulled out. How often do you change the oil, what weight are you using??

[@tortillamilk]

Ha! I lost my shit when u pulled out the hatchet!

[@marvinmartian2630]

Have a mk1 also with the same problem, contemplating on either rebuilding the engine or swapping it, monies tight right now though :/

[@d4a]

Marvin Martian Sorry to hear that. Rebuilds are fun too. What kind of swap? When swaping you will very likely need to spend money on the new engine too, to replace a few things.

[@marcos9885]

I see this is an old video from July and probably you have already sorted out the `crazy idea` to do with the car-engine.. probably the bike carbs, have you considered turbo the engine as it is ? It`s crazy enough just to take advantage of the spare engine, another idea is to install nitrous oxide kit and see how good can it run.

[@PP-vs3jd]

What did you ended up doing to the crank? Did you polish, cut or discard? Or maybe just used as a door stopper

[@d4a]

That would be one hell of a door stopper 😂 I ground it and it's in my engine that I'm driving still. Worked out well.

[@PP-vs3jd]

@@d4a machinist or in the backyard?

[@troye5555]

Great video!

[@DasSnakeBoy]

Like the choice of tools

[@ralphtaylor787]

I’ve got a 1995 K1500. 5.7. It developed a momentary rattle on hot start up. So I replaced all of the rod bearings. I now have a small knock on one cylinder.

[@marcusmarrs]

If you have/had a spun bearing, couldn’t tell, you really should get your crank reground by a competent machinist along with resizing your connecting rods. This way there’s no guess work, “this looks fine, this doesn’t, etc”. You start fresh. Also, should be obvious to replace your oil pump as well.

[@tashamullins7572]

I laughed out loud when you grabbed that axe! 🤣🤣🤣

[@dustinwestphal4333]

Did you have measure the rod bearings before installing them they look like they were too tight?

[@d4a]

I did. Here's the deal. I bought a set of new OEM bearings according to the numbers printed on my crank and block. Plastigaged them and had the machine shop measure them. I was right on the outer limit of the clearance prescribed by the factory. So I went one size thicker on the bearings to reduce the clearance. Machine shop said the initial clearance was fine already, but said that the thicker bearings are good as well. They measure again and confirmed and I plastigaged again. Clearances were all good. But after looking at a bunch of failed bearing images, mine seem to look like ones that were too tight. Hmmmm

[@w0lvez1]

driving 4 answers Did you used NEW ROD BOLT? Most engines used Torque-To-Yield (TTY) Bolts on connecting rod, main bearing cap & cylinder head.

[@Simon-xi8tb]

this guy can detect rod bearing wear just by smelling oil pan bolt. This is some next level Bunta shit :D

[@pidgon08]

You rock.. I have similar pain with my 1994 chevy diesel. I should let it die... retire it but it only has 400000 miles on it. It's still a pup🤣
