Anyone who pronounces the name 'Porsche' the correct two-syllable way definitely gets my respect ! 👍👍

[@StormsparkPegasus]

It's much harder to find someone who pronounces Volkswagen correctly. I took 4 years of German in high school/college. But people in the US look at me funny when I pronounce it correctly. In a nutshell, German doesn't have the English w sound. Instead, the w is pronounced like the English v. And the v is pronounced like the English f. And the a has an "ah" sound rather than the "eh" English uses.

[@wglnaeclipse8715]

Feel free to throw the water pump as hard and far as possible. M96 water pumps are a known failure item; replacing them is "routine" maintenance (like every 50k miles IIRC). Nice to see the engine torn down as far as it was; I now appreciate my 996's motor that much more.

cool video Eric, there were no indications of lubrication failure in the parts you removed and examined so I totally agree with your decision to not strip the motor any further 👍

[@RadDadisRad]

I had a 2004 986 S and tore my 3.2 out and did the IMS repair and sold the engine for a big chunk of money because it ran and was worth something. Bought a wrecked 2004 Carrera S 997 and pulled the 3.6 M96 and swapped it into my 986 S. With cams intake and exhaust it made 360whp. Thing was an absolute rocket. Sold it last year for $25k. It was bittersweet selling it.

[@d00dEEE]

Yeah, I hear ya. I've got a 1997 986 chassis with the 3.4 and bigger brakes swapped from a 2001 Carrera (the original 2.5 had an IMS failure, who woulda thought?). The '97 is the lightest 986 they built, which is nice, and the motor with headers, some ECU tweaks and good intake plumbing puts out about 290whp on the dyno. Nowhere near your 360, but still gets you into severe traffic violation territory at the slightest twitch of the right foot.

Even though you had to stop short ( perfectly understandable ) it was interesting to see the engineering ethos of Porsche. I am always fascinated to see how each engine builder drives their camshafts and valvetrains which, I feel, is their engineering signature. In this engine, everything seemed to be built to have a solid purpose with as few frills as possible. As opposed to Audi which seems to think the more parts, the better. If you have the chance to take apart an Audi V8 you will see what I mean. Keep them coming!

[@gsxerwhite]

I'm in the same boat. The timing cover removal is my favorite part. The Bentley tear down blew my mind, gear driven timing.

Love the respect you show to this engine.

[@simplygregsterev]

My guess is someone might have went to change the IMS cover seal or even IMS and didn’t have the camshafts locked. It jumped time and valves hit when started. The only annoying part rebuilding these engines is finding a place they can deal with cylinder liners. Those bores look excellent The real sad part is the valves are pretty cheap to replace.

[@genegtaylor]

I concur with this. There's no way the contact happened when Eric turned it over manually. It had jumped time and made contact prior, likely when someone attempted to service the IMS. Bummer the engine was scrapped when it could easily have been repaired.

This one was interesting. I bought a Y2K Boxster S used for $25K and it was a great car. I was enjoying it for a few months until I heard about the IMS failure that could happen without warning, and Porsche wasn't backing it up with any kind of recall or warranty. I took the car to a Porsche car show hoping to sell it when I discovered a 28K mile black 930 turbo coupe for sale for only $31K (before the big price surge). So it all worked out peachy. That Boxster engine makes music and it did run great but I wasn't about to dump $15K into a new engine just in case it decided to explode backing out of the driveway.

The RTV in the pick up screen is most likely from a leaking rear main seal replacement. If the seal has been replaced multiple times, or “required” RTV to install it, it is very likely the casting of the case where the crank exits is oversized or not round. That was the issue with the M96 motor in my Carrera. A very common problem. You mentioned the IMS failure to be blown out of proportion by the internet? Well it was bad enough for a class action lawsuit to be won against Porsche, so I’d say the problem was pretty widespread.

[@yosefallam9722]

I have a 24-year-old 2000 Porsche Boxster S (built in late-1999). Never had the engine removed or apart, zero engine issues except for an AOS replacement and a couple of coolant reservoir leaks, failed water pump replacement (very dramatic barfing of coolant under the car as I backed into the garage), plus cracked ignition coils that were overdue for replacement, and all of which I kept up on and replaced myself. That's it engine-wise. Every time I change the oil or plugs they look great, as well as the oil filter which I tear open to check every pleat for debris. Always pretty clean except for used oil. And I drive it hard every day, even through mountain switchbacks at 12,000 feet altitude. These engines like to be wound out responsibly. Mine still goes like stank. Generally, if you have nice things, you have to pay attention and take care of them. Is there still a chance of catastrophic failure? Yup. But you can do your best to minimize that probability and a little luck helps. Porsche is indeed a two-syllable word. 😉

[@ronaldderooij1774]

True, although I also follow a reputable German engine specialist (Redhead. sorry, YT videos are in German) who said on YT that Porsche Boxster engines are not standard meant to go on trackdays. If you want to drive them that hard, you must say so when purchasing them and you will get a stronger engine (provided you pay extra, of course). He also mentioned what differences there were, but sorry, I forgot. Personally, that would be the limit for me. Paying extra to do what the car was meant for is beyond me. And oh, coils are not parts that should ever be replaced routinely. In principle they should last the engine. I know that is not always the case, but still.

[@sutherlacd27]

​@@ronaldderooij1774the coils Porsche used prior to roughly 2010 eventually degrade and crack. In roughly 2010 Porsche updated the coils and they are much better. When people do the spark plugs on cars with the previous style coils they're recommended to update them to the latest version.

As an owner of a 2004 986 3.2S this was really interesting. I have owned mine from 10 000 miles and it now has 27 000 on it. After mulling over the IMS bearing issue I decided I wanted to be able to drive the car as intended without constantly listening for the first signs of a failed bearing and had it replaced with an improved aftermarket item from EPS. These cars sound best when driven from 4000 rpm to the red line not that you can do much of that on the public road.

I know you went to profit because you are a business, and I also remember you saying you hate taking apart something that's working. I appreciate that there will be some back-blow from people that just want to see a complete tear-down of this engine so justifying for the business needs to be emphasized when I'm confident that it being a working bottom is a great reason to stop there for anyone who has worked on engines before.

Big fan of this channel. Weirdly cathartic to see engines being stripped down and the pathology of why they failed. Also have learned about how IC engines are engineered. Thanks for sharing.

[@unavailablenumbers]

This looks like the shop diagnosed a Variocam failure (which does happen,) took it apart to start the repair (hence the marked caps,) found the cam was completely dead, and found the piston damage. Being a 3.4L M96 and susceptible to bore scoring, putting a known good used engine in became the cheaper option. It probably just needs the head reconditioned, but then you're pulling the engine, resealing it, may as well do the IMS while you're in there, pulling the pistons is likely to score the bore, you need all the special tools, all the labor, etcetera. I could easily see this being written up as a $40,000+ estimate. "Or, we can put a good used M96 with a new IMS in for about $15k."

The Subaru H6 WAS NOT easy to service. I had the misfortune of having to do timing chains on one. Much like this engine, the entire powertrain had to be dropped. Even spark plugs are right against the frame rails on both sides of the engine bay. Granted they are one of the more reliable Subaru engines but that’s because there’s nothing to them.

[@mitchellpatterson1829]

That's the power of German engineering.

[@sp33d4l0l]

These things were made during a time when Porsche was in bad shape financially, so they had to cut costs by reusing the same head casting for both sides. That's why there's timing chains on both sides of the block. Keep in mind the Boxster S 3.2 was intentionally tuned very conservatively so it wouldn't interfere with the base 3.4 911, and that 260hp figure is for the EZ36, not the EZ30 (which made 220 or 240 depending on the year).

@@JohnEvans-ct6mzmight want to try reading. I said the EZ30 was *easier* to service than the M96.

Hey, no worries. Business is business, and nobody wants to work for a loss. It was more than worth it, to watch that engine come part as far as it did...👍👍

Iirc the Intake cam isn’t staked on this engine. The central bolt can loosen over time (or not torqued on previous repair) and it will eventually lead to misfire faults. If you don’t catch it and drive home the bolt comes out too far and will prevent the cam from spinning. The loose cam sensor was probably the diagnosis and they assumed (incorrectly) that the cam had broken.

Im so happy you didnt tear down that engine completly. It was hurting me to watch that engine teardown as the engine was in a very good condion. Hope somone rebuild that engine. Hope we will see some destroyed Porsche engine one day. Thanks and here's the like nonethless.

[@phillipwalker8018]

You do have a business to run and profit is definitely a good thing. Smart move on your part to end it where you did. It was interesting to see how the engine was put together. Thank you for that bit of it. Take care.

IMS issue is cars that were rarely driven and in salt air climates. A garaged engine that is routinely driven is not a problem. The IMS bearing itself is sealed, but the seal pops off. Then the bearing gets splash lubricated and remains fine unless it gets exposed to air and moisture, because it's metalurgy is intended for it to remain sealed. Best way to counter the corrosion issue is by using HD diesel oil, like Rotella or Delvac. In extreme cases you can use a marine oil.... LiquiMoly makes some if that helps.

Of course there are some differences between mounting in Boxster and 911. In Boxster the engine is mounted right in front of the rear axle and in 911 it is mounted right behind the rear axle.

No need for the apology, you’re a business and as much as I love you tearing an engine down to the last nut and bolt you don’t need to do that to your financial detriment just to appease the masses😂 I look forward to you getting a GT3 engine in for a tear down

[@darylmorse]

Good call not tearing down the short block, as much as I would have liked to see it. It was really interesting to see this video, even though you didn't tear it all the way down. This engine looks like it's in very good condition and it should be possible to rebuild it, even considering the intake camshaft. I hope you do really well on this engine, because you deserve it.

For bore scoring- the 2.5, 2.7, and 3.2 do not suffer from bore scoring as much as the 3.4+ motors to

[@dkjens0705]

Your Variocam cover is an oil scavenge pump. All cam caps, heads and cam covers are marked from the factory. Nice to see that you handloosen the internal 5mm allen head bolts, someone must have told you to do that or they have a tendency to strip. Before removing oil pump housing you should have removed the cam chain tensioner. If a head has cracked you'll have oil in the coolant and/or coolant in the oil. Looks like the owner didn't change the oil as much as they should have. They probably tracked this car causing oil starvation to cylinder 5 rod, happens to all the M96/97 engines. If tracking these cars please invest $800 into the 2 liter deep sump, that will save the engine.

[@jasonruch3529]

Thats how every engine should be built! Loving the top end! Its like a high performance bike engine

[@blackmanops3749]

Ummm...did you miss the part where he said it was a core? Based on the comments It failed due to bad design.

[@frankmartin8471]

No need to apologize for not ruining a factory original Porsche short block. Nice video.

[@DangitBobby...]

I look forward to your videos every week and always learn something, thanks for doing what you do!

[@blueplasma5589]

Where else in the world can you see complete tear downs , your pick! Lots of thanks. One of the simplest engines, 1.1 Opel from a GT.

[@2VintageRacer2]

I enjoy watching Eric's work. A+

[@bonose12]

Well done and i appreciate leaving the short block unmolested. Just that one intake cam...head scratching here. Taking care of the business never a poor choice. Thx Eric.

[@pauldietz1325]

It was fun watching you be so gentle with this engine.

Bought my first LBZ Feb 2006…drive it 629,750 kms - then was stolen Jan 2023. Bought an 07 LBZ CCSB SLT. BEST motor, great trucks. Bypass Oil filter, Titan Tank, FASS….all 3 liberated from found stolen n smashed up 06 truck…

[@rodanone4895]

bore scoring is a far far bigger problem than IMS bearing. I've had to repair that one. thankfully it wasn't D chunk. the critics are AWESOME! they kept these cars cheap enough that i have four of them. each one.... Camry money. including a twin turbo with the Mezger.

[@gregkimura5906]

Back in 2006, my 986 threw the IMS through the block. I did a very spirited drive home one evening. On the way to work the next day, she drove great - felt like the engine had loosened up and she revved much faster. That evening, I drove to our corporate office - she still felt great and then it happened. It sounded like I ran over something, then I remember hearing a sound like the honeycomb material in the cat had broken free and was blocking the exhaust. When I got to our corporate office, I dropped off the paperwork, then started her up. She sounded rattly and the CEL was now on. I barely got her to the freeway entrance ramp (she was sputtering and felt like she was running on 3 cylinders). I don't know why, but I decided to get on the freeway. Very slow acceleration, but soon got up to 65-70 mph. Got to my office, parked her on the top floor and traded cars. When I was driving past her, I noticed a large puddle under the car. I got out and checked it - oil! The next day I called my local Porsche dealer. Luckily it was still under warranty. 23K miles on her (2003 MY car). The local Porsche dealer had it towed to their shop. When I asked the service writer what their diagnosis is, he told me the shaft went through the side of the block and it's a covered claim, so I shouldn't worry. I asked if the IMS bearing went out. He told me he doesn't know, but the dealer is not allowed to tear the engine apart. They ship it back to Germany and the Porsche techs tear into it. It took about 2-3 weeks to get a new engine installed and get my car back. The service writer told me that the replacement engine has the new style IMS bearing.

The biggest surprise in this video was the lack of bore scoring. Good move not tearing it down further. An enthusiast would no doubt pay big $$$ for it in this condition!
