[@jodybarrett8832]

Having seen this in turbo cars with the boost cranked on stock internals, I can say with 100% certainty here that the oem compression rings aren't gapped to handle the boost you're running. When they split in two like that, it is due to the gap closing under boost and heat. When the rings expand to the point that gap closes, those forces have to go else where usually splitting them 180 degrees out, like what you pulled out of the block. For the sake of longevity of this rebuild, I can't stress enough that you upgrade your rings and open the end gap on them. Love that truck of yours, hoping I can at least save you some future headache with her if you do wind up seeing this. Looking forward to the rebuild progress!

[@stayfree1613]

Just got done doing a fresh bore ALH rebuild for my Cherokee swap, You send it out get the bores done, Then you bring it home and assemble everything with new bearings. With the nural asv's you'll notice its about 10ish thou too short, go back to the machine shop and have them take that much off. ( not 10 thou exactly but around 8 to 12 thou) shoot for a 1 hole gasket. When I rebuilt my engine I ended up having to get new rods because my piston protrusion measurements were off. Bought IE tuscan rods and all my measurements were very close. Had to swap a couple rods to get the measurements spot on. Remember its all about the compression. Break in procedure for these engines is very specific. I'm sure your on the forums scouring information like I did. If you have any question about the rebuild hit me up.

Stacey Freels that’s what I ordered! From my research the oil squirters don’t need aimed with asv pistons, just for arl! Unless I’m missing something!! Let me know

[@stayfree1613]

From the Research I've done your gonna want the oil squirters aimed at the oil galley hole. both at tdc an bdc. other than that they will be squirting at the bottom of the piston like they would with the stock pistons missing the oil galley hole.

[@ajmartinez1026]

Might look at the injectors. I had a 5.9 cummins that blew the side out of an injector so I was getting a ton of fuel in the oil causing oil/fuel to overfill and come out the ccv tube

[@bartvanos]

Just a heads up, the crankpulley bolt needs to be replaced. one time use only! had mine break once. that was no fun

[@jamb312]

Are you sure the turbo isn't leaking a crap ton of oil from you possibly destroying the seals when you turned the truck off, and it was still really hot? I have seen engines diesel and gasoline that invested a lot of oil from the PCV or turbo that destroyed the valve seals and piston rings.

[@amorag59]

What intercooler did you use? I'm looking for one like that that has the in/out on the same side with a air flow "uturn" on the side opposite the in/out. Edit: nevermind! You were gracious enough to link your build list in the description 👌.

[@BolteBuilt]

[@mickhirk4734]

You have to run more Ring GAP with BOOST or you will do the same thing again.

[@turbocharged798]

Hey I have rebuilt a few of these engines, Nural ASV pistons are a great upgrade and cannot be beat for the price. If you are going with the oversize ones, they have a shorter piston height. You can usually get away with the thinnest 1 hole head gasket on those. The best part is that they have oil cooling ducts and the ring land height is much lower so the rings hold up better. Just have the machine shop skim the top of the block and you should be OK for height. I usually build up the bottom end first and then measure the piston height and pick a head gasket based on that measurement. I am building a motor now with maxpeeding rods and so far they check out OK. Can't recommend them until I get some miles on the engine but the price was right. Apparently all the H beam rods are coming from the same place in China anyway.

[@austinniemela]

Thats what i have read!! I did the .5mm over ASV pistons and will be decking the block to get my piston projection back in spec!! Just waiting for the rods to come in!!

[@harrysack8834]

I had this happen with a 475 cat, no ring in #5 piston and oil leaked out the blow by

[@nikolakardonsky9108]

Good luck bro

[@haydenerlandsen8295]

The valve seats may be recessed, which that case it would leak compression. But you said its low on all 4, so it probably is a bottom end issue. Good luck

[@culinarygraffiti]

What transmission you running on the yota? new to your channel, maybe you got a video I can't find that talks about it? pretty awesome to see a complete tear down of an ALH.

[@spoolin610]

You can have the machine shop check it but it's by the hour for them to assemble the rotating assembly. You can make up for out of spec protrusion with head gasket thickness but not sure what is available for tdi's.

[@austinniemela]

I will do all that, i meant have the machine shop check out the rods and make sure they are all good!

[@hawkie333]

[@austinniemela]

ellerbeeweston injectors are new and all calibrated. They didn’t look hot, mainly just wet from not burning

[@Mikefngarage]

Your really lucky it did not do a runaway situation.......if the oil rings cracked it would have ran until it fragged. Those engines are very expensive to build.

Hate that happened, definitely something with the piston rings, valve sealing issue, or head gasket if your compression is low.

[@jeromecampbell7214]

Dude,how did you attach the quick disconnect on the gauge for the compression tester. I bought the same kit but the coupler is hitting the head and injector bolt and won’t allow me to engage it

[@austinniemela]

Jerome Campbell that’s wierd! Mine bolts right in! Make sure it’s the longer adapter

[@chdrev21]

Only advice I’d have is make sure you tap your rings properly for boost. Most likely the added boost made the rings butt up and snapped them when it got too hot from ripping it

[@austinniemela]

How much ring end gap would you say?

[@evanolson8819]

Check out Frank Irving of Frank’s TDI. He goes by Franko6 on the forums and is an extremely talented machinist. Offers a full range of services for the TDI’s all the way down to CNC porting the cylinder heads. ASV pistons are alright, but BHW pistons with Molnar Technologies connecting rods will be the most bullet proof set up you will find. Lots of guys running that set up on compound turbo 300+ HP ALHs. Also.... I’ve watched a few of your videos and really appreciate them, however, I’m not surprised to see broken rings on your motor with how Smokey that tune is. Unburned fuel leads to high EGT’s, peak cylinder pressures, and low volumetric efficiency. Definitely find someone who is a experienced diesel turner that can correct your map accordingly after the engine is rebuilt.

[@austinniemela]

Evan Olson fueling is going to be turned down. However I never saw over 1400 degrees ever!

[@evanolson8819]

Austin Niemela interesting, you definitely were getting peak cylinder pressures that the rings couldn’t handle. More likely a symptom of high boost on a stock block like you said. The stock ALH piston rings are way too close to the top of the piston, not enough room for cooling and cause issues when more heat and pressure is added over stock. The BHW pistons aren’t any shorter than ALH pistons so you won’t have an issue with assembling then having to shave the block way down. BHW pistons are superior to ASV in my opinion and Frank’s. Also if the car has a stock 2 hole or 1 hole you have a lot of of room to play with. As for measuring the protrusion make sure you use a deck bridge and 2 dial gauges to get the most accurate measurement. I’m not going to comment on anything else as I know you’re an experienced mechanic.

[@bmt973]

Impressed and gutted at the same time. You are truly a jack of all trades. Loss of time and troublesome motor is the ultimate pain. Consider this option: en.wikipedia.org/wiki/Toyota_KZ_engine I once owned this pickup. I believe it's ideal candidate for the turbo and intercooler you already have... I traded in mine because I needed a double cab. It was bullet proof just like most Toyotas. Good luck.

[@BenLinn]

omg this guy knows his stuff

[@austinniemela]

Thanks!!

[@thomasmurphy5906]

Maybe the stock ring end gap was too tight for the boost you were running, something to think about ☮️

[@amorag59]

My first thought

[@UlisesGlez26]

Too bad it blew up, but that means just more awesome content and your truck will be at 100%!

[@greengeeker1]

You got the process right. Have your machinist bore it out. Then bring it back to him after you've measured protrusion with new pistons and rods. I'm really surprised to see the failed rings. I was betting $ you had bent rods given your mods

[@austinniemela]

Cool! Yeah i really dont know how they broke! Ring end gap wasnt too terribly tight (.38mm)

[@recovery5667]

Rd28 is the perfect swap for them best small 6cylinder diesel

[@dobermann2013]

Those things happen. Nothing to worry too much. Poor lubrication can cause piston rings to overheat and lose their tension. Faulty piston rings can be as a result of: incorrect installation, improper dimensions, fuel flooding, inadequate combustion of the fuel/air mixture, and/or abrasive particles in the oil, and tiny chips left after machining could be a reason for this failure too.

[@adamdiscovery8181]

[@HumbleGolds]

wow. what caused those rings to burst? is the turbo too much??

[@austinniemela]

I’m not sure why!!

[@360VRStudios]

Such tiny engines!....are they easy to work on?

[@madcratebuilder]

Did this ever get hot? I've never seen a burned valve in a diesel. Scuffed cyl walls, broken rings? It is wounded for sure. You can build it bigger, stronger. ETA: After watching all the video I would see if you can buy a .003 or .005 over piston/ring package, otherwise bore to next oversize. You don't want the new piston rocking in the cylinder, you want it tight spec.

[@gregh7457]

He said the bores looked good so there must not be any scratches that can be caught by the fingernail. So if bore size is within spec and there is no taper then no need to bore
