[@michaelfortier7726]

Quick tip to save the engines: WRX engines don't have baffles in the oil pan, while STI engines do. When tracking a subaru, the oil shoots towards the outside of the turn (towards the head, because of the horizontal layout of the boxer engine), starving the oil pump leading to premature rod bearing failures. It's a quick and easy upgrade to swap out the oil pan for one that has baffles, and it solves the issue (aftermarket, or STI pan). (It's not an issue with city driving, but the long high-speed turns at the track make this mod a requirement to be somewhat reliable)

[@edekitrex]

If you’re going to replace stock just get a KillerB kit or something with better pickup tube as well and usually more oil capacity.

[@roblucchetti2993]

This happens in a lot of cars, Honda suffers from the same thing, that's why when i built my civic, a baffled oil pan was high on the list of items that went in. Pro tip: Buy a baffled pan with baffles welded in. After-market kits that make you rivet or screw into your pan, then seal the holes ALWAYS leak. spend the loot for baffled pan. Once of prevention is worth $10,000 of cure

[@jordanlatta]

As soon as I heard it running I was like "yep, spun bearing... piston is traveling too far up the bore and hitting the head"... Confirmed at 9:01 😔 You can see the part of the head near the bottom of the screen has a distinct ring of new-looking metal where the piston has beaten the carbon build-up right off the head surface. Didn't really need to go any further than a noise test to know what killed this engine, but hey... it was fun to watch these boys smash their fingers 😅

[@WillemDodd]

Would you happen to know if the newer sti oil pans will work on a 2016 wrx

[@FoxMacLeod2501]

@@WillemDodd @Kxngs If you don't find the information you want on the part manufacturer's website, I would recommend searching one of the many WRX owners' forums and message boards. You can use Google to search within a website: just enter the website URL, then a space, followed by your search terms. From my basic Subaru knowledge, WRXs have used the completely redesigned FA-series engines since like 2014, while the STIs still run the old EJ-series engines. They're mostly not interchangeable as far as I know. So, my educated guess, to answer your question, is: No. I highly doubt the oil pan from a "newer" STI will fit a 2016 WRX. But my big tip is: don't rely on KZbin comments when you're trying to buy car parts.

[@scotchbingeington6761]

Absolutely, and even then you need to be mindful of it. I watched something similar happen to Pastrana, who keep in mind, was driving a Vermont SportsCar built STi. Baffles, dry sump, all that. If anyone knows how to build a Subaru it's those folks. He went off near our spectator point at a rally, and the car was leaning over a bit to one side in the ditch. Once a sweep vehicle came through and got him pulled out, he immediately went hard on the throttle once the engine turned over. Sure enough, about a minute later exhaust sounds in the distance abruptly stopped. Then 20 min later he came walking back up the road with his co-driver Beavis. Asked them if they went off again "nope, pretty sure we blew it up". Word got out later when the mechanics and engineers got a chance to tear into it that it was an oil starvation issue, likely due to the car sitting on its side in the ditch and then immediately given WOT. I think there's a video here on KZbin as part of Subaru's "Launch Control" series that has in car footage of that debacle playing out.

It was good to see more real engine work being done again. I used to watch more but then began to ignore a lot of your episodes not realizing you sold the company. Anyway good follow up on failure. I feel better knowing all my break in practices weren't a waste of time after all. So many times people ragged on me saying pro racers and mechanics didn't bother with all the directions and fussing around. I just wanted to try to fully understand how everything works together. And for me it seems like it worked out well. After 45 years I've learned anything I really wanted to with the confidence to pull it off when I couldn't afford to swing big more than once. Plus I survived because of that understanding sometimes when I probably shouldn't have.

[@aaronthomas6155]

Pro racers do in fact break in engines before pushing them on the track. Anyone that thinks otherwise, is completely clueless.

@@aaronthomas6155 I know that they do I've been around racing since front engine rails like Don Garlits in the early 60s. Then Can Am and road racing at B.I.R., Riverside, and Pamona. But most people I've known just didn't understand what was really going on beyond back yards and stock cars. I was just more interested and lucky to have such good influences around. Years in a machine shop really made me see things on another level too.

[@122martin122]

Before assembly you would need to change every bearings and make sure to redo the cylinders honing because right now its a ring file, 90 degres hash, should be 35 to 45 degres. Mesure your pistons and cylinders after doing so. That engine still seems fine. We can see that it had piston dust on the cylinder head from that gray tint. Test for valves leakage with compressed air from the intake and exhaust and brake cleaner in the chamber, there should be no bubbles. The plugs looked fine. Nice video keep it up!!!

[@theodorgiosan2570]

I don't have any experience with EJ engines, but I have a huge amount of experience with the earlier EA engines. EA engines hate thin oil at high RPM, they spin rod bearings with it. All I will run in an EA71 or EA81 is Aeroshell 15w50 aircraft oil. For a few reasons. #1 is it "sticks" inside the bearings. I have taken engines that have not run in weeks and they still have oil in the rod and main bearings. No startup noise whatsoever. #2 is it's an ashless oil, it doesn't create deposits when it burns. Very little in terms of cylinder wear on these engines running this oil. #3 is the TCP (tricresyl phosphate) antiwear additive. It prevents scoring on the camshaft and acts as an antirust agent as well. #4 is the level of protection at high temperature. Even above 275 degrees oil temperature, the extreme pressure capability of the oil is well over 100,000 psi. Never had an EJ but that's what I would run for oil. Also runs excellent in big block Mopar engines and 1950s Early Hemi engines. Compatible with leaded fuel as well.

[@DarkMan2555]

Thanks for the informative comment. I never even thought of using aircraft oil in a car engine. Another alternative to the Aeroshell oil (due to price/availability) you recommend is Shell Rotella T6 5W-40. Admin Tuning recommends this oil "because it keeps a more consistent oil temperature and is less volatile."

Don’t forget to check your oil- Fellow STI owner

[@enjoipanda1337]

this is normally only an issue with earlier models like 02-05 (I believe they have 06-07 despite what was said in the vid) due to the shape of the oilpan. A good preventative mod is upgrading the oil pickup / baffle and even the pan if you have some extra funds. I recommend iag or killer b. Do frequent oil changes, tune accordingly, and give it some time to warmup on cold start. Your motor will do great.

[@philipsavage4396]

I have a 2011 STI. It came with an aftermarket 6 quart baffled oil pan and twin pickups as opposed to just one as stock. Seriously- before you do any mods do that.

[@wortexinternational2598]

They did say that this might have been a culprit but in reality it was a combination of that along with no oil at the rod bearing. Maybe adding a little more oil or using baffles in the pan could help.

[@gravyd316]

It's a crap shoot. I'm betting the block wasn't decked in the rebuild. Subaru blocks warp just as bad as the heads when over heated. A good rule of thumb when rebuilding a Subaru engine is to look at the knock sensor. If it's melted just toss the entire block. It's most likely warped to the point where it'll give you a deceptive look of bad rings and bearings at the same time. You could end up putting good internals in a bent block and repeat the entire process again.

[@The_G4M3R46]

Can we all agree that subaru does pretty good with manufacturing a motor that can be worked on without taking to much time, with only a couple to a few hours he had the engines stripped entirely down

[@AlDim000]

No. Spark plugs alone are a 2 hour job that requires removal of the secondary air pump and tiny, tiny hands. Basically anything that's on the sides of the engine is a huge pain to service. Also, removing the intake manifold requires disassembling every single thing on top of the engine and takes several hours. Taking the engine out and taking the short block apart may be relatively quick, but it is significantly more difficult to rebuild than inline 4-cylinder engines and requires highly specialized skills, knowledge, and equipment. The only thing we can all agree on is that Subaru makes absolute trash engines which are extremely prone to catastrophic mechanical failures such as rod knock, ringlands failures, headgasket issues, etc. Many of their engines tend to have uneven cooling (pretty well every engine with unequal headers tends to stress one cylinder more than all the others), drink oil quicker than a rotary thanks to excessive blow by, have oil pickup failures, and on top of all that they are very expensive to make decent power reliably. In conclusion, don't get a Subaru. That's from a Subaru owner.
