Eric it looks like that poor thing was run without enough oil. My 05 Jett holds 7 quarts of oil. I've been told to never run it low on oil. 5 quarts is not enough to keep it from cooking itself. Thank you sir for another great video.
I had a Jetta also with the 2.5 and I also needed the same amount of oil. It is a noticeable difference compared to some 4 cylinder engines that only hold 4 quarts. The Nissan Rogue I have now has a 2 liter engine and it takes 4 quarts (maybe a smidge less than that) and they advertise a 5000 mile oil change interval for that vs the 10,000 for the VW 2.5. Of course depending on the oil you use 10,000 miles would be way too many for it. I am thinking about the average crap found at Walmart for example (I don't actually buy that stuff!!)
The manual for my 2014 2.5 says 6.3 quarts. The VW dealer where I bought it new, would only put 6 quarts in, and call it good. That would only get the level up to the "add" mark. The newer VW engines take less oil. The owner might have taken it to a quicky change place that would only put 5 quarts in, or the guy only took it in for an oil change when the oil light came on? I don't know what oil consumption is like on these, because I have the oil changed every 5,000, instead of the 10k VW specifies, and the oil is always still on the "full" mark.
Considering the damage here and the clean oil up top, it's impressive. It's clearly ran low/out of oil, started making a racket so they put oil in it (finally!). Poor thing
@@gldgti I wonder if NO oil was put in at the oil change? No oil until bad sounds started happening..the oh shit moment... and then 6.4 quarts of new oil got circulated but all the glitter was already on the pan floor.... and the noise made them shut it down and declare it dead very shortly thereafter?
My girls 2012 jetta is almost at 200k and it's had little issues here and there but nothing super bad now the rest of the car like the moon roof was dog water the interior has fallen apart 😳 like the panel on the passenger side between the door and seat . The map light section has cracked and the head liner has begun to sag that being said it's a 12 year old vehicle .. then I look at my 02 blazer xtreme the head liner is fine the interior isn't falling apart .
@walter68bug98 as of right now I'm pretty sure yeah, I got it with 180k on it last June Havent done the vacuum pump delete yet, but have put a newer 5 speed in it for WAY better fuel mileage now
@@DrivingInFocus I also believe it doesn’t have low tension rings. I also forgot to add that it also specs for VW 502 00 5w40 oil which is a really good approval for non direct injected motors. Great protection.
That “thermostat housing” is a gift from God, they have the same plastic housing, basically, on the 2 L and you can freeze that thing solid fire it up and drive it for an hour while it thaws out the ice and all you have to replace is that housing, ask me how I know I will tell you
Perfect, nothing i wanted to watch on TV! As a retired mechanic, i like the way manufacturers hide bolts, a treasure hunt!! Merry Christmas 🎅 🎄 to you and the family!
Definitely one of VWs underrated engines. I see them in my shop with 220k miles quite a bit and not much going on with them. As far as reliable inline 5s go, id say late 90s-early 2000s Volvo might be the golden standard.
I had an 05 Volvo XC90 with the 2.5 liter. Bought it just before covid used as a mechanics special after another vehicle of mine was totaled. I had to do the PCV service which required dropping the oil pan because the drain back to the pan was solid carbon. Even after that and almost 200k miles on it the engine looked fantastic inside. Once the PCV service was done, new timing belt and water pump, new plugs and coil packs, fluids swapped, brake pads and rotors swapped and struts and control arms along with new ball joints, I drove it back and forth to work for 3 years and put about another 40k miles on it, for maybe $4k all in on the car. Was excellent. Gave it to a friend of mine when I moved away and he's put another 15k on it. That engine will probably top 300k easy given how it looked.
@sergeizakharkin4908 Yeah my 2003 S60 with the 2.5T was solid but the car felt haunted. If I got out the car and locked it, it would randomly lock and unlock itself for like 15 seconds. The most bizarre experience Ive ever had with a vehicle 😄 It would only do it once every 3 weeks though so it wasnt too annoying
@@timesup6302 Not sure if its problem solely with the early P1 platforms, like my oldie cruiser, but 90% of electronics issues Ive encountered were because of a sub-optimal battery. Just about fixed every electronics problem got fixed with a new battery (the designed flaw sunroof is not doing any early P1 chassis owners any favors for the last 10%)
I have a 2010 Golf with a 5-cylinder like this, and I LOVE it! I put a straight pipe on it and it sounds like a Lambo when I romp on it! I only just passed 125k miles and the car has never had any issues. I love seeing the other comments from fellow happy owners.
Check the vacuum pump area -- that's on the timing side of the engine. Chances are you will find an oil leak there. It seeps through either of the two gaskets in the pump, but most often through the one between the cast iron engine block and the aluminum pump body. It's a very common problem on this otherwise great engine and probably has nothing to do with the driving style or maintenance habits; it just happens after a certain time/mileage. I had mine changed at around 140K, but I am sure it had been leaking for a long time before I found out (my mechanic never told me about it!). It is a "silent" leak. In my case, the expelled oil never dripped on the plastic shield on the bottom of the car or the ground. Instead, it just spread itself on the surrounding engine block and transmission cowl surfaces. You will need to inspect that spot with a flash light as it's kinda buried deeper down. The vacuum pump replacement can be a DIY job if you don't mind getting your hands dirty and voiding the warranty on the new pump. This is because the removal of the original pump and installation of the new one requires removal of the outer cover plate of the pump so that you can flip the darn thing over the protruding shaft of the transmission shift selector. The latter part also must be removed... There are a few UA-cam videos on how to do this pain in the neck job. If not the DYI route, dropping the transmission is the only remaining option. As a matter of fact no mechanic will agree to do the repair in the DIY style. Naturally they want to make the money, so prepare to shell out well over a grand for it... Of course, you can probably keep driving with the leaky pump and the grimy engine. In that case, check the oil level regularly, which you should probably do anyway. 🙂
Hey, I own one of these engines! It’s in my 2-weeks project car that I’ve been fixing for 8 months… (electronic gremlins). I can confirm they sound great and they are fun to drive. Mine is (for the moment) hooked up to a 6-gear Tiptronic which in a convertible is fine, I think… It’s great to hear that they are reliable: we never officially got them in Europe and now Volkswagen is in a deep meltdown -> the only support is what I can do to it.
Important note at 2:00, the first iteration of the 07k made 150 hp and 170 ft/lbs of torque. This iteration was used in the MkV body styles (05.5-10). The second iteration of the 07k made 170 hp and 177 ft/lbs of torque. The bump in hp comes from a redesigned exhaust manifold as well as a slightly different intake manifold if I'm not wrong.
I would argue that the 2.5 is the best engine vw has made, requires very little maintenance and it runs forever. My 09 rabbit has 515k on it now and that is after just getting back from a 9k road trip with zero powertrain issues. I literally beat the piss out of mine, redlining it all the time and towing 5k LBS or more with it on a weekly basis. Unfortunately the body will be rotten before the motor is done
Not to be pedantic, but there were two variants of the 2.5 we got in the US. We had the BGQ/BGP which made about 150HP in the earlier MK5's, then the later MK5 and MK6's had the CBUA/CBTA which made 170HP. I've got a 2008 Rabbit with the CBUA and a 5-speed manual and it's stone-dead reliable. It's got typical VW intermittent issues, but otherwise it's a great engine.
Brother inlaw has this engine in a gti with a five speed transmission, very realiable but hard no fuel . With the EA888 that replaced this 2.5 there is alot things VW changed in the engine design to make it endure 330 hp in the Golf R 2.0L. Great tear down , and Thanks.
Looked like it had been run for a long time with stuck rings on that cylinder the piston just slapping around in that cylinder not being centered by the rings I'm sure the check engine light was doing the blinking thing screaming you have a serious misfire
Most reliable engine I've ever owned was the Mercedes 617952 3.0l turbodiesel in a 1983 300D-T. I sold the car with 450,000 original miles on it and the new owner kept driving the car until it rusted away to nothing. That engine was incredible - it simply never failed and never required any repairs. 8 qts. of oil at 3k intervals.
I had many of the Mercedes 616 and 617 engines. I did manage to ruin a 616 (don't ask how; I actually am not sure) but had a 617 that came to me with a bad knock and I drove it for ages that way, even turning up the fuel injection and thrashing it. Its final pull for me was a 1 ton diesel van full of scrap metal up a steep hill several miles long. It hated me for it, but did it. I eventually sold them all, including the knocker, as running units. Very tough engines.
I’ve heard multiple accounts of people reaching over 500k miles on original engine, I personally did 200k miles without a single thing breaking and it never burnt oil
Subj: Cosmopolitan elocuence. Thanks James for the detail, as a non English native speaker I'll take that to enrich my vocabulary and verbal elegance. Eric ⭐👍.
I want your "Give it to me straight" shirt. That engine had a lot of metal transfer in that one cylinder. Overheated is an understatement here. Watched many of your videos. Seen many destroyed pistons. But never until now have I seen a melted piston. Great video!
They probably quit making it because of CAFE and EPA standards. All these complicated turbo motors for the benefit of 2 or so MPG just doesn't make sense to me. They won't last nearly as long which means more environmental impact than any potential savings. STUPIDITY
@@daves3402 They were talking about fuel economy, not emissions. While burning slightly more fuel per mile does slightly increase emissions, they are not really the same conversation.
Reminds me, I always take trips to Detroit coming from Toronto, up until 2019 as you approached Windsor/ detroit about 100 miles out you could literally see a brown haze off in the distance covering the 2 cities..then in 2018 the Ontario government scrapped emissions tests, and suddenly there were more catless cars than before and by 2019 you just simply could not see any brown haze over the 2 cities from a distance as you approached it not to mention a lot of people have since moved to windsor cashing in on the inflated toronto prices and til this day i dont see any more brown haze as i approach windsor/detroit...my thinking is a bit crude but seems like going catless cleaned up the atmosphere there lol

The unique growl of the 5cyl is awesome. I had an early Audi 5000 and with a mild after market exhaust, it was smooth And reliable with proper maintenance.
Finally! I’ve been asking for this engine for months now. Now we just gotta see that one liter three cylinder Mitsubishi motor that comes in the mirage
That rocking piston would look great as a desk trinket. When you launch engine parts across the shop at your employees, give a good loud warning like INCOMING!!!
Finally, an engine I can get behind! In my case, I owned 5 Acura Vigors with the G25A1 5 cyl. I even built a block from scratch after buying a new crank from the dealer - don't think that didn't turn heads at the parts counter! Pretty bullet proof, but my first one broke the cam, necessitating a rebuild. Cheers! Biker Bill in Little Rock
I had a 2012 VW Passat 2.5L with the 5-spd manual. One of the few xars i ever regretted trading. What made these engines so good in terms of longevity was the slightly more complex timing chain configuration. Shorter timing chains means less total stretch. Which is why the later model cars that had the timing chain guides & tensioner problems resolved lasted so long. This is one of the few VW group engines with rear mounted timing chains that DONT need to serviced before ~100k miles at least for later model cars. Compared to the other VW offerings, that had timing chains on the back of the engine these were great!
That is one gnarly piston. That thing got heat discoloration on the rod, but it didn't melt the piston at the wrist pin which is incredible. The scrappy side of that piston definitely got hot enough to spread around the aluminum with the friction. I can't imagine that piston staying together much longer. A few more miles and I suspect we would have had a few inspection ports and a disconnecting rod going to war to create some piston nuggies in there.
My sister bought an early production 05 Jetta 2.5 new. Sold it 3 years ago at almost 200K running beautifully. Didnt burn oil. Other than the typical Mk5 quirks - sagging headliner, conductor plate (replaced at 135K), cooling fan module(only replaced once at 100K), and the sprayed on coating on a few interior switches, the interior and original paint were mint. The woman who bought it for her daughter thanked my sister for it being so immaculate compared to everything else she looked at.
Replace vacuum pumps on these engines, the odd oil filter housing, and occasionally rear main seals. Definitely one of VW's better engines. Nothing at all like the later 2.0 TSI garbage!
That's right -- I had to replace the vacuum pump and the filter housing after over 10 years of ownership. I hope the rear main seal will last the life of the car.
The rear main seal is easy to not have to replace...just stay on top of replacing the pcv valve/oil separator as vw likes to call it as with any car that makes more blowby/ crankcase pressure as the engine accumulates miles and loosens up...til date have never had to replace a rear main seal...I actually managed to suck a rear main seal back into place by routing my block and head pcv vents to pre turbo inlet on my former 1988 thunderbird turbocoupe after a few days of commuting
@@monikhushalpuri I replaced the PCV valve at the same time as the vacuum pump. The mechanic did say the crankcase ventilation system in all VWs & Audis is poor. Somehow they did it without replacing the entire engine valve cover. I think some of the oil loss I've experienced in recent years may be attributed to the old PCV valve and the leaky vacuum pump.
I got a 11 Jetta with the 2.5 with 230k it never left me stranded. The only things I replaced were the plugs, coils, oil, filter, and belt. Other then that it been cheap to own as a beater
One thing you should know is VW recommends 10k oil changes. And the cap is stamped Castrol. But I always change mine at 5k. Shoulda removed the wrist pin on the rocking piston, I wonder if the bearing showed signs.
I've seen some videos lately where inline engines have been mounted on the engine stands sideways instead of at one of the ends -- at 2:50 it seems there was some places that "might" have worked --
As a VW hater, these are great motors. Seen lots of them push 200k with the automatic transmissions just on routine services. I've always secretly wanted a Rabbit with a 2.5. Just avoid the Turbo TSI 4 cylinders at all costs.
If you do retain the head for resale (I assume you already know) the cam bridge plate has to go with it. VW/Audi mills the head. Line bores the journals and then slices the bridge off making the tolerances unique for each engine.
One of my ex girlfriends had a beetle with this 2.5l 5 cyl engine in it. Not gonna lie, it was a surprisingly fun car to drive, and that engine did sound really good. I begged her to let me put a cold air intake on it so the induction noise would be louder, but of course she wouldn't let me lol.
I had a 2006 Jetta with a 2.5L manual, and I loved the sound, the torque, the features, it was a blast... for the most part. Sadly the car itself was a smouldering dumpster when I got it (it was cheap, and I needed something quick), which had turned into a full raging dumpster fire of a vehicle by the time I managed to get rid of it (to some guy who was desperate enough to buy any cheap car ASAP as much as I was desperate to sell it). I'd definitely get myself another 2.5L though, preferably that's in better condition than the one I had, and when I have ample funds to soak up the VW maintenance premium.
Hi Eric, nice mid week tear down. Honda made a 5 cylinder fitted to, what is called here(NZ) a Rafaga. Quite an odd layout of north/south engine, front wheel drive. A couple of guys I know use the 2.5 litre engine in off roaders. They sound amazing and rev to the moon! Cheers, Bryce😊
I believe we got that engine too, Honda sold it as the Acura Vigor sedan here in the states. They're neat little cars but quite rare these days. Our well-salted winter roads ate them up.
Another great tear down. I suspect it ran low on oil cuz they never checked it between oil changes and it was a long time between oil changes. Probably happens a lot 😒
Vw also makes a 2.5L TDI that they put in the Touareg and transporter vans. Really strong engines with gear driven timing system makes them sound like they're coming apart 😂 but a bloody torque monster! Will rip the tires off!
That engine is bad compared to late 1990s 2,5TDI. Those older engines run 1M miles, without any issues. Many old taxis here in Finland have over 1M km and some even 1M miles. That new 2.5TDI is good also, but cylinder head wears and pumpduse start leaking diesel to oil

I don't think of anything VW/Audi as reliable.
They won WRC championships, so they had to be both.....
22:17 It's so metallic in there it's asking for fuel, fire, and that which it desires!
OOOOOOooooo YEAHEAH
Well that's going to be stuck in my head the rest of the night. White knuckle tight!
Well played!
Add another malapropism to Eric's vocabulary: "The next first thing I'm going to do." @ 4:50 🙂
Subj: Cosmopolitan elocuence.
Thanks James for the detail, as a non English native speaker I'll take that to enrich my vocabulary and verbal elegance.
Eric ⭐👍.
To be fair, he didn't want the next thing to feel like a loser coming second, so he made them equal. 😂
His way with words is what makes his videos so entertaining 😅
A bonus mid-week teardown. Thanks for that Eric!
I want your "Give it to me straight" shirt.
That engine had a lot of metal transfer in that one cylinder. Overheated is an understatement here. Watched many of your videos. Seen many destroyed pistons. But never until now have I seen a melted piston.
Great video!
Your shirt reminded me of the engine that was in my ex-1977 Datsun 280Z. It was an inline 6 Cylinder.
I had one with the 5-speed manual. Transmission ate me out of house and home, but the engine was bulletproof.
Jeep 4.0 LEGENDARY 💯👍😎👌✌🏻✌🏻
@@dantesinfernopurgatory7826 The 4-SPD was standard. Years later, the 5-SPD could be added. The 5th Gear was Overdrive.

Had a bunch a early VW bugs,
Bajas lots of fun…..
Thanks for another VW engine. I would love to see a tear down of a VW 1.4 TSI. it doesn't have a dipstick tube for you to fight with!
Humble Mechanic has a solid 1.4 teardown, he's also done the W8!
@@griffinetchison4064 Thanks. I have seen that one. I want to see the 1.4 get the Eric treatment.
The timing chain tensioner pop gets me every time 😂😆👌
"I'm taking shrapnel!"
This is my favorite tear-down that did not involve a post-manufacturing inspection portal.
They probably quit making it because of CAFE and EPA standards. All these complicated turbo motors for the benefit of 2 or so MPG just doesn't make sense to me. They won't last nearly as long which means more environmental impact than any potential savings. STUPIDITY
You would have loved LA in the ‘70s. No stupid epa rules, and lots of respiratory disease. Do you enjoy poison in your water too?
@@daves3402 They were talking about fuel economy, not emissions. While burning slightly more fuel per mile does slightly increase emissions, they are not really the same conversation.
@@daves3402 CO2 doesn't cause respiratory disease. Any modern car produces almost zero oxides. The 2.5 was ditched for MPG, not emissions.
Maybe you shouldn’t live in a town of 4 million. 🤷
Reminds me, I always take trips to Detroit coming from Toronto, up until 2019 as you approached Windsor/ detroit about 100 miles out you could literally see a brown haze off in the distance covering the 2 cities..then in 2018 the Ontario government scrapped emissions tests, and suddenly there were more catless cars than before and by 2019 you just simply could not see any brown haze over the 2 cities from a distance as you approached it not to mention a lot of people have since moved to windsor cashing in on the inflated toronto prices and til this day i dont see any more brown haze as i approach windsor/detroit...my thinking is a bit crude but seems like going catless cleaned up the atmosphere there lol
ENGINE REQUEST --- 4.2L inline 6 out of 2007 +/- GMC Envoy or Chevy Trailblazer. Just wanna see the innards. I have an 07 with a P0203 code I was gonna fix over a weekend ... 2 months ago. I'm patient/persistent though; I'll get it. Compression test next good weather day. You're my favorite UA-cam video every Sat nite. Natchez MS ... in da 'Sip.
The unique growl of the 5cyl is awesome. I had an early Audi 5000 and with a mild after market exhaust, it was smooth
And reliable with proper maintenance.
Audis were junk
@@toddbob55 And they still are.
Finally! I’ve been asking for this engine for months now. Now we just gotta see that one liter three cylinder Mitsubishi motor that comes in the mirage
As a former 2.5 driver, this video was a lot of fun. Thanks Eric!
Your narrative is a riot. You're doing tear downs that we all wish we had time for. Great editing.
That rocking piston would look great as a desk trinket. When you launch engine parts across the shop at your employees, give a good loud warning like INCOMING!!!
Fore!
Finally, an engine I can get behind! In my case, I owned 5 Acura Vigors with the G25A1 5 cyl. I even built a block from scratch after buying a new crank from the dealer - don't think that didn't turn heads at the parts counter! Pretty bullet proof, but my first one broke the cam, necessitating a rebuild. Cheers! Biker Bill in Little Rock
I had a 2012 VW Passat 2.5L with the 5-spd manual. One of the few xars i ever regretted trading.
What made these engines so good in terms of longevity was the slightly more complex timing chain configuration. Shorter timing chains means less total stretch. Which is why the later model cars that had the timing chain guides & tensioner problems resolved lasted so long. This is one of the few VW group engines with rear mounted timing chains that DONT need to serviced before ~100k miles at least for later model cars. Compared to the other VW offerings, that had timing chains on the back of the engine these were great!
You need to find a volvo 5pot!
My precious Jetta engine! Ill take this as a "how not to reck it"
Always enjoy learning from your videos, so interesting.
That is one gnarly piston. That thing got heat discoloration on the rod, but it didn't melt the piston at the wrist pin which is incredible. The scrappy side of that piston definitely got hot enough to spread around the aluminum with the friction. I can't imagine that piston staying together much longer. A few more miles and I suspect we would have had a few inspection ports and a disconnecting rod going to war to create some piston nuggies in there.
My sister bought an early production 05 Jetta 2.5 new. Sold it 3 years ago at almost 200K running beautifully. Didnt burn oil. Other than the typical Mk5 quirks - sagging headliner, conductor plate (replaced at 135K), cooling fan module(only replaced once at 100K), and the sprayed on coating on a few interior switches, the interior and original paint were mint. The woman who bought it for her daughter thanked my sister for it being so immaculate compared to everything else she looked at.
Whoa, this was epic! Keep it up!
Bot, go away Maggot
My mom had a Jetta with this engine. Decently quick and a great runner.
Need to see a GM 2.7 turbomax teardown since I own a truck with one in it curious to see any failures on these engines.
Maybe the secret is that nobody ever changes the air filter on that thing.
It's cause they can't find it😂
Buy the Hengst air filter when you do change it....
Good to see you again Eric . Thanks for posting.
Replace vacuum pumps on these engines, the odd oil filter housing, and occasionally rear main seals. Definitely one of VW's better engines. Nothing at all like the later 2.0 TSI garbage!
That's right -- I had to replace the vacuum pump and the filter housing after over 10 years of ownership. I hope the rear main seal will last the life of the car.
The rear main seal is easy to not have to replace...just stay on top of replacing the pcv valve/oil separator as vw likes to call it as with any car that makes more blowby/ crankcase pressure as the engine accumulates miles and loosens up...til date have never had to replace a rear main seal...I actually managed to suck a rear main seal back into place by routing my block and head pcv vents to pre turbo inlet on my former 1988 thunderbird turbocoupe after a few days of commuting
@@monikhushalpuri I replaced the PCV valve at the same time as the vacuum pump. The mechanic did say the crankcase ventilation system in all VWs & Audis is poor. Somehow they did it without replacing the entire engine valve cover. I think some of the oil loss I've experienced in recent years may be attributed to the old PCV valve and the leaky vacuum pump.
This video is motivating me a lot to finish my project car, which has one of these (the 150 HP version).
Thanks Eric!
I got a 11 Jetta with the 2.5 with 230k it never left me stranded. The only things I replaced were the plugs, coils, oil, filter, and belt. Other then that it been cheap to own as a beater
Love this tear down ❤
Absolutely crazy 😧
THANK YOU. I've been waiting for this episode. I'm one of the many requestors.
If that oil was any more metallic, Lars Ulrich would file a copyright claim against it. :)
Wow. An oddball 5 cylinder tear down and a trip to a Metallic concert all in the same post. Why I like mid-week videos.
Very interesting content, subscribed.
One thing you should know is VW recommends 10k oil changes. And the cap is stamped Castrol. But I always change mine at 5k. Shoulda removed the wrist pin on the rocking piston, I wonder if the bearing showed signs.
Audi engineers: "So how many points of failure do you want this engine to have?"
AUDI: "YES."
I want to maybe one day build a mk3 golf with a 07k and 6 speed
Love that shirt. Recognized it right away. Jeep 4.0!
I've seen some videos lately where inline engines have been mounted on the engine stands sideways instead of at one of the ends -- at 2:50 it seems there was some places that "might" have worked --
Eric it's time for an Alfa Rimeo engine...
vacuum pumps fail a lot on those and it is easily mistaken for a bad rear main seal. Replacing either of them is a somewhat laborious job!
20:24 I'd love to see how many 10mm sockets are in the parts room hahahaha
As a VW hater, these are great motors. Seen lots of them push 200k with the automatic transmissions just on routine services. I've always secretly wanted a Rabbit with a 2.5.
Just avoid the Turbo TSI 4 cylinders at all costs.
Speaking of the Nissan 300ZX , have you ever torn down a VG30DETT , brilliant videos , keep up the good work Eric .
I had a 5 in my 1993 Eurovan, it was rated 105 HP. My 2001 was a huge upgrade in many ways.
Those were old 2valve engines with belt. Reliable too but sluggish.
@@juhomaki-petaja Thanks. Brakes faded, too.
Nice shirt!
My 2002 4.2 Trailblazer straight 6 that I bought new is still running strong at 247K 🙂
This has been a really good month. We’ve been getting two a week. I guess this would be our Christmas presents
Both my kids have VW's with 2.5L engines. The daughter's Golf is close to 180k.
One of VW's top 5 engines.
Oh yeah! Thank you for this one
I've owned a couple of Jettas, the body rusted off by about 200k but the engines were still going strong.
If you do retain the head for resale (I assume you already know) the cam bridge plate has to go with it. VW/Audi mills the head. Line bores the journals and then slices the bridge off making the tolerances unique for each engine.
Had 2.5 in a Rabbit, ran GR8😊
One of my ex girlfriends had a beetle with this 2.5l 5 cyl engine in it. Not gonna lie, it was a surprisingly fun car to drive, and that engine did sound really good. I begged her to let me put a cold air intake on it so the induction noise would be louder, but of course she wouldn't let me lol.
I think I recall you doing a 5 cylinder Audi.
Save that large spring in the oil pump. Perfect replacement for a recoil spring for an AR-15.
I really love that T-shirt showing the only proper engine configuration
Glad to see this episode. Got 254k miles on mine in my Rabbit. Going strong, engine will out live the body sadly though
I had a 2006 Jetta with a 2.5L manual, and I loved the sound, the torque, the features, it was a blast... for the most part. Sadly the car itself was a smouldering dumpster when I got it (it was cheap, and I needed something quick), which had turned into a full raging dumpster fire of a vehicle by the time I managed to get rid of it (to some guy who was desperate enough to buy any cheap car ASAP as much as I was desperate to sell it). I'd definitely get myself another 2.5L though, preferably that's in better condition than the one I had, and when I have ample funds to soak up the VW maintenance premium.
Woke up and was shocked with this episode right on the screen of my tv. Absolutely stoked considering i own a couple of these engines 😆
You make sloppy tear downs (on admittedly bad engines) solid gold in terms of the humor.
I had an ‘06 Jetta with this engine. It wasn’t particularly powerful or fuel efficient, but I didn’t have any issues
I had one in a VW Transporter twin cab Pickup. First gear wouldn't work, but that motor pulled from second gear like a champ.
Speaking of 5 sylinder engines... would love to see an om617 torn down one day.
Tear down of a 1.6 eco boost from fiesta st perhaps?I know you’ve done 1.6 eco boost from escape/ecosport but would love to see the st variant
Hi Eric, nice mid week tear down. Honda made a 5 cylinder fitted to, what is called here(NZ) a Rafaga.
Quite an odd layout of north/south engine, front wheel drive. A couple of guys I know use the 2.5 litre engine in off roaders. They sound amazing and rev to the moon! Cheers, Bryce😊
I believe we got that engine too, Honda sold it as the Acura Vigor sedan here in the states. They're neat little cars but quite rare these days. Our well-salted winter roads ate them up.
please do 1.8 20v next
Can’t beat my 1985 sohc 1.8 L in my GTI
Another great tear down. I suspect it ran low on oil cuz they never checked it between oil changes and it was a long time between oil changes. Probably happens a lot 😒
Happy Holidays Eric to you and your family Thanks!
Thank you buddy! ❤️
Just in case I don't see another one of your videos till after Xmas,Merry Christmas! 🎉🎉 Hope you have a wonderful one 🎉🎉🎉❤❤❤😊😂😅
That engine looks like a robust design. Change your oil! Another great video Eric!
Any engine will break, if you neglect it enough. Change your oil, people.
Vw also makes a 2.5L TDI that they put in the Touareg and transporter vans. Really strong engines with gear driven timing system makes them sound like they're coming apart 😂 but a bloody torque monster! Will rip the tires off!
That engine is bad compared to late 1990s 2,5TDI. Those older engines run 1M miles, without any issues. Many old taxis here in Finland have over 1M km and some even 1M miles.
That new 2.5TDI is good also, but cylinder head wears and pumpduse start leaking diesel to oil
I just love the detail that you put in your videos ❤👍
Great teardown, thanks for sharing the video. 👍
I wish this engine was still made. It was a fun and very durable engine for me
