Why Inline 5 Cylinder Engines are an Anomaly

Here's a look inside a Volvo 5 Cylinder engine, how it works, what caused it to fail and why inline 5 cylinder engines aren't that popular anymore!
The engine in this video was taken from a 2005 Volvo S40 and suffered from oil starvation and coolant mixing with the oil. In this video, the B5244S4 inline 5 cylinder engine is torn down to take a look and what caused it to fail, how it works, the component setup, a discussion on its integrated lubrication and PCV systems and engine balance.
Skip to the sections in this video:
0:00 Introduction
1:14 Teardown
7:54 Engine Lubrication
11:17 Positive Crankcase Ventilation System
13:57 Engine Balance
The Volvo B5244S4 is a modular design that scalable from inline 4, inline 5 and inline 6 applications on the same production line. It features an aluminum design, with a lubrication system integrating the valve cover and oil pan. The head is wide, having dual overhead cams situated far apart from each other. The version shown here is naturally aspirated and has variable valve timing on the intake side only. The valve-train is driven off a timing belt.
The cooling system integrates an externally mounted oil cooler, while the PCV system uses a unique oil separator to extract oil from the crankcase before venting it back into the intake plenum.

[@lshurr]

Maybe this is the best, most cogent explanation of engine vibration I've ever seen. He even remembered to include the inline 4's vertical shake, but he didn't mention the problem with torsional vibration in an inline straight six. Reminds me of a documentary elsewhere on KZbin about the history of racing at Mercedes Benz. Mercedes started racing again in the 50's. Torsional vibration is usually managed by including a vibration damper at one end of the crankshaft, but Mercedes thought that if they put the power take-off in the middle of the crankshaft, then they could also shorten it and reduce torsional vibration that way, but they were wrong. In an interview with one the engineers who designed the new engine, as he chuckled, he explained how they ended up having to put vibration dampers at both ends of the crankshaft, resulting in a longer shaft than they would have had otherwise.

[@trevor311264]

My Korean-built car (It has an MB 5 cylinder engine made under licence) has vacuum engine mounts that adjust themselves dependant on the engine RPM. When idling there is very little vacuum and they lift up and dampen the vibrations more. But as you rev the engine harder the vacuum in them builds and pulls them down compressing the internal springs making the mounts become stiffer as the engine movement is less of a problem. So to surmise, Low RPM, wobbly mounts with the engine sitting a few inches higher, high RPM, engine mounts pulling engine down stiffly to the chassis.

[@brettkirkpatrick464]

Fantastic explanation of many tricky points. The detailed breakdown of the oiling system was phenomenal and the pcv box disassembly truly demonstrates how that system can (and does fail). The explanation of the firing order and comparison to other engines is what puts the video over the top. I originally viewed the Subaru engine teardown and now I'm convinced that speedkar99 is doing something unique.

That's disconcerting. Oil cooler failures are a rarity on these engines (Volvo "white block") and not treated as a maintenance item. I have two of them. Ford bought Volvo mainly for this engine and used it in some early 2000s models.

Oil cooler failure is actually not that much of a rarity. The external oil cooler failed on my whiteblock at under 100k miles. Fortunately I caught it quickly. I’m at 266k+ miles now on the same bottom end. Daily driver, 2000 V70 B5244S.

“Oil is not a good coolant” *Mutters angrily in air cooled*

And oil still isn’t a good coolant. That’s why they are _air cooled_ engines, not oil-cooled. Spent many a summer day waiting for takeoff in a light aircraft with oil temp edging towards the red, 60 weight oil pressure almost nothing, hoping that the plane would still climb with the extra 20 knots I was going to add to climb speed to try and keep the the engine from overheating. Then the opposite... coming down at 200MPH in icy winds and unable to reduce power to increase descent rate without shock cooling. Oil is best for lubricating.

The 2.4l engines are a little better to service, as the oil filter is top-down and the PCV trap is separate.

[@zzoinks]

Great! One issue I'm scared of is there is a PCV banjo bolt in these engines that has a metal ball inside and it has been known to unluckily break and cause the metal ball to get sucked into the engine and cause damage. They released an updated banjo bolt, but it seems like either a snapped timing/accessory belt or a broken banjo bolt can be the immediate death to the engine! Pine Hollow Auto Diagnostics made a video on the Volvo where the banjo bolt broke. (there is an updated banjo bolt that doesn't break)

The plastic style pick up tube actually has better flow and doesn’t clog up as easily and is considered an upgrade on older engines. I’m guessing it is difficult to create that shape with metal in mass production so they used plastic. It works well and has proven to not be an issue.

When GM pulled out, AMC was forced to create a "new" six by adding two cylinders to its four.

Inline 6 is the king of engines. Most industrial engine companies are now focusing on inline 6 and v12 engines, as the parts crossover between the two are excellent.

Damn, this man has his ICE knowledge nailed! Impressive. I will have to disagree on the top mounted cartridge oil filter setup being more prone to messes.

Also, most of them come out with the cap. But for filtering I still prefer the spin-on canister type filters.

The older versions of these engines use steel oil pickup tubes. Know a few people who worked for Volvo back in the day and by the time Ford had more influence they did some cost cutting (though I wager the cast saving is minimal if you factor in the price of a mold to make the plastic parts for the pick up). No extra chain to oil pump - nice Big oil channels, easy to clean, because of the bed plate construction also very easy to manufacture (no deep holes to be drilled) Bed plate construction (the upper oil pan) make the engine block really stable. I remember the bearings reside in steel inserts? 10 bolt connection to the flywheel - beefy Steel water pump impeller, probably still the original pump too.

Dang, lack of maintenance killed this Volvo. I have a 2004 S60R and around 220,000 miles now on it. On these, the sandwiched cylinders is only an issue on the 2.5 blocks, namely the 2.5 in the r. Under high boost, there is a chance for the cylinder wall to crack, expelling exhaust gases into the coolant system. The fix is usually either shimming the block, in the thin space between the cylinders or resleeving the block with new Darton sleeves. The head gasket can be replaced with the r/t5 one for better reliability, as they are used for the all out high HP builds. The PVC system is notorious for issues, you can use the glove test method to see if you may have an issue. These Volvo 5 cyls are only as good as the maintenance. If you are on top of it, they last forever, however if you are a slacker, it will die. You can't treat it like a Honda/ Chevy. On turbo Volvo's, the turbo isn't integrated with the manifold, so swapping is fairly easy. Also, the Volvo 5 and 6 cyl motors have many swappable with minor modifications parts, ie pistons and such. Since they are a modular design. It's common for people to take the t5 pistons and swap them into the t6 motor. The valve cover has a liquid gasket. In the end, these are absolutely fantastic motors for people willing to do the work. They, with some modifications, can be absolute monsters and fairly reliable, it's just you need to be a stickler for maintenance.

[@veoverse4286]

Yeah, that needed better oil management (fully synthetic, and changed on schedule) and it looked to me like it needed more long trips. Volvo designed these engines to be used; short trips will kill them if you don't go for an Italian tuneup every once in a while. They're not as tolerant of neglect as the old red blocks, but when looked after and treated well, they're just as durable.

​ @speedkar99 Was looking forward to this video ever since the subaru engine video,where you showed a sneak peak,My brother has a volvo c30 with the b522s4 engine in it that failed, started producing a lot of blowby in the crankcase causing the intake cam seal to pop off, after replacing the seal as we assumed the crankcase pressure might be because of a faulty pcv membrane,it still started pushing the cam seal and we later found this was due to scoring on one of the cylinder leading to excessive pressure in the crankcase (the cause of the scoring which i intially assumed was when the cam seal came of and he lost oil pressure, but when we tore it down, all the main bearings had no damage and everything indicated there was no drop in oil pressure as he caught the leak quick enough. I saw a small chip of metal missing from the piston crown and welded back on the side of the piston crown causing it to score deep lines in that cylinder liner,Such a weird failure mode, I realized later that,once when someone else was driving the car one of the vaccum lines on the upper intake plenum leading the a evap purge solenoid valve broke off and the engine was suddenly exposed to a massive vaccum leak on the highway, which may have caused a few detonation to remove a small sliver of material from the piston crown and weld it at the other end of the piston causing it to score the cylinder. (the theory is that fuel trims couldn't adjust quick enough to control the massive lean condition caused by the vaccum leak on the highway leading to the detonation that killed it as described, thought i would share that because that was the very first time i encountered one of this

I owned a 2007 Chevy Colorado with a 3.7L 5cyl inline. That engine was smooth and had good torque.

[@PetesGarageandperformance]

I used to work at a Hummer dealership and worked on a ton of the I5 engines. They were relatively smooth, but for some reason would always break exhaust manifolds and manifold bolts. I always attributed it to the 5cylinder design. Although it could’ve just been crappy manifold castings.

[@khoov48]

Mines a 2005 3.5l l5 Chevy Colorado. Supposed to be famous for soft heads and leaky valves too...? (Updated from 3.5l to the 3.7l in '07-'12 models) Mline has 160k miles on mine and it's all original engine parts, head and manifold even. I love my 5 cyl Colly, gonna run her till she can't no more. Thing does run smooth, like new everyday. I really run my pickup, keep up with the maintenance, possibly even just luck of the draw.. I change oil via oil life indicator, tells me when to "change oil soon" and I run Quaker State full synthetic 5w30 and change the spin on filter every oil change, sometimes every 5k m. The oil change indicator usually runs 10k and no more than 12k intervals

Brilliant tour through that engine, happens to be one of my favorites (in the turbo variety).

[@hereigoagain5050]

Another great video. Its almost as though the engineers get tired. "Well, we are 95% done with this super complex engine. Let's finish it off with some cheap, plastic bits."

[@makecba]

that's wasn't the engineers, blame accounting...

[@lehelzelenka207]

Generally the plastic parts-given they are quality made- tend to serve the engine through it's lifetime. It makes the engine lighter, cheaper and all other stuff that matter like how quickly can an engine warm up to operating temperature. An 80Kg engine warms up faster than a 90Kg engine.

[@ameunier41]

Those plastic bits didn't look cheap by any means. They seemed in perfect working order. Even the PCV look in good condition, it's the seals and valve that goes to ghost.

[@blubase06]

These are so damn interesting and I didn't know I was actually able to keep up quick enough to actually learn how this engine operates.

[@steamerjohn9212]

Wow, I have no need to know anything about a 5 cylinder engine but this video was filmed and edited so well I enjoyed viewing every bit of it. Well Done!

[@speedkar99]

Glad you enjoyed it!!

[@josephdragojevich7041]

i love these engines, they used the same block for nearly 25 years, meaning you can go to a junk yard and find parts very easy. the bottom end of these engines are nearly bullet proof, its the valves you have to worry about, if the valve stem seals are allowed to leak then you will burn an exhaust valve leaving you with no compression.

[@jessewildman1292]

Great vid. Was looking forward to this one. I have 6 volvos and 5 of them are older than 1998. I honestly don’t like these newer versions of the 5 cylinders. The original N version from 93-98 was the best. The oil pickup was metal like you were saying it should be, there weren’t as many oil passages because it didn’t have VVT, and the cylinder walls were a little thicker. The RN 5 cylinders that came after were ok too, but they introduced VVT, and for whatever reason, it seems like the tolerances were much tighter and therefore they were much more prone to throwing rod bearings plus the cylinder walls weren’t as thick, so the higher HP models were prone to cracked blocks. I love the original N 5 cylinders. Best reliability, durability, and longevity. I currently daily drive a 94 850 with 328k on it.

[@rex_s80]

Depends on what motor you got. The older 2.4L turbo N was 83mm block as well. The later RN 2.4 T5 (not 2.4t) has 81mm bore. It’s really dependent on which bore block the motor used rather than N vs RN. the 2.3L t5 used 81mm. I would say the move from hydraulic to solid lifters for the Rn as long as mechanical tensioner was an improvement. I do agree about the rod bearings for the 04+ RN when they did a semi engine facelift for the p2 models. The cylinder heads for the RN have more flow than N head. Even more than a stage 1 ported N head. Ups and downs of both. But we can both agree the RNC is just a mess in comparison 🤣 . (The one in the video)

[@jessewildman1292]

@@rex_s80 Yeah, it does depend on the trim model for the motor. I was mostly referring to the R line of the P2s and also the 2.5 T5 RNC motor. Yeah, the solid lifters, mechanical tensioner, and better flowing head were nice, but the benefits kinda outweigh the cons for me. But yeah, RNC is the pinnacle of garbage. 😂

[@charliepirhonen9734]

Love your videos. Its amazing seeing the journey the oil takes in engines.

[@johngroberts952]

The “plastic” parts in high temp area are Pa6-glass fiber reinforced which can be stronger than metal. Also much less susceptible to heat cracking.

[@speedkar99]

Good call. How about warping and leaking due to heat?

[@MrWeisbrod]

That's good to know! However, the plastic tubing that makes up large parts of the cooling system gets very brittle after 100,000+ miles. I love my s40, but miss the simplicity and durability of my 850 (same engine, basically). While my favorite engine to drive is the inline 2.8L straight six from BMW, I must say I love the unique feel and sound of 5-cylinder engines, especially Volvos.

[@derekinbritishcolumbia1449]

The plastic coolant hose from BMW's engine block disintegrates after about 20 years. I was not impressed when my daughters 318i overheated after loosing coolant. Removal of the intake plenum was required just to gain access for replacement. Not a fan of plastic engine parts.

[@shodanxx]

[@rampage3337]

@@derekinbritishcolumbia1449 yeah plastic is not a good material for those kinds of parts. it's used becaus it's cheaper

[@Dwrecksk8Yo]

Yea those plastic pieces are actually made from a glass and plastic mix which makes it relatively strong and it lightens everything for emissions and it dissipates heat very quickly. It’s the same type of plastic ford used for their thermostat housing on ford escorts and I’m sure other cars and trucks. But couldn’t the oil cooler have failed internally which mixed oil and coolant.

[@cdjhyoung]

The standing water in #3 bore suggests head gasket failure.

[@looncraz]

@@cdjhyoung I think someone removed the spark plugs and this engine was left out in the rain, I've seen the 5-cyl gasket failures and they're clearly visible... this one was fine, AFAICT. In fact, nearly every issue with this particular engine came from using the wrong oil. These engines REQUIRE high quality synthetic. Mobil 1 or better. I tore down my 850's engine at around 200,000 miles (for fun) and didn't have even a tiny amount of sludge.

8:53 Actually replacing the oil filter is not messy at all, you can remove the filter without leaving a single drop of oil on the engine. Spin-on filters, at least to me whenever change them on a Chevy express, those are a mess EVERY TIME. Source: I do my oil changes on my S40 and C70 BTW: Great video and nice editing.

[@speedkar99]

I've got cars with both. The cartridge always leaves you open to dripping oil, not to mention cleaning out the housing and Changing the o-ring. Many manufacturers have gone back to a spin on style

[@johnroberts1505]

@@speedkar99 then you must be doing something wrong. I have two autos with top mounted oil filters and I have never spilled a single drop. You just have to wait a little while so that the oil drains down. Autos; BMW 330i, Ford F150.

[@CEHepp]

speedkar99 Before draining the oil, loosen the filter and let it sit. While you’re doing other work, like draining the oil, the filter housing will drain. No mess.

[@MrWeisbrod]

I love the cartridge filter of my s40. Much better for the environment (less waste), and I find that it drains just fine. You just have to be patient, as the others have noted. In fact, it is a much "less-messy" oil change when compared to the downward-pointing filters on my wife's Honda. It also allows you to "prime" the filter a bit with new oil (which I can do on my Honda, too), unlike older upward-pointing screw-on filters.

[@233kosta]

I like the cartridge ones, they're less hassle. Also, for some reason, manufacturers seem to think that less filter should cost more... the mind boggles...

Same here. When I first saw a spun bearing in a G35 engine it was quite interesting to think how something like that could happen. That engine was worse and had a cracked crankshaft.
