Swapping engines

And the engine could still blow up from other things, as you mentioned.

If "speed costs money" and someone wanted to go faster, they probably wouldn't buy a Boxster.

You have a point, Al. I'm certainly not going to fork over several thousand bucks to have a LN-approved shop install the Solution in order to qualify for the 5-year warranty. However, Jake Raby indicated that DIYers should nevertheless go through the registration procedure, including sending LN the old bearing. It will provide proof that the Solution has been installed. That's really all I care about, because it's unlikely the warranty would be needed anyway.

Haha, thanks. I watched a video about Doug DeMuro's acquisition of a Carrera GT. Kudos to him, but I believe I derive as much enjoyment from my inexpensive 986 as he does from his million-dollar hypercar. Ditto with Hoovie and his Bugotti Veyron.

If fact, a some engines equipped with the Solution have suffered other types of failures (rod bolt failure, spun bearings, broken crank, dropped valve, etc.) and the Solution was removed from the failed engine, cleaned up, and installed in the replacement engine; something you cannot do with any other style of IMS retrofits.

Yes, they are more expensive, but "speed costs money; how fast do you want to go?"

My guess is that lawyers nixed LN providing a transferrable lifetime warranty with the Solution. Too bad, because a limited warranty on such an expensive item gives potential buyers pause. Not me, though. The product registration is the important thing.

The Single Row Pro IMS Retrofit is covered for two (2) years/24,000 miles from the date of part installation."

I'll bet LN originally wanted to offer a transferrable lifetime warranty. "That wouldn't be wise," lawyers no doubt advised them. And to think I almost went to law school...

Oh, I totally get it. That's why I do all the servicing on my cars myself. When I had more time, I even swapped and rebuilt engines. But not on the Boxster (yet). The only thing I can't do is rebuild transmissions.

Looking forward to reading up on your progress.

The IMS cover flange appears to have a shallow dish, which means it's a dual-row bearing. Oddly, the flange is secured with hex-head bolts. Every other one I've seen used Torx. Ees a puzzlement. Perhaps I should replace them with Torx? In any case, after the lift table arrives I'm going to pull the bearing and eyeball it before I order the new one.





I also drained the oil from the new engine and removed the filter and inspected it. It was clean as whistle, of course.

The bolts came both ways, most were hex headed.

Your IMS Solution kit will include new bolts.

I've watched it done. Seems pretty straightforward, a step at a time. If your transmission went south I bet you'd roll up your sleeves, as would I.

Edit: Upon reflection, it's more likely that I would pay a visit to eBay and find a replacement transmission, and you'd probably do the same. But it would be interesting to rebuild one. They're like a big metal puzzle.

The closest I came to rebuilding a transmission was replacing the tail housing on a 2011 Outback. I found a 29K mile one that was wrecked and the rear mount broke the tail housing. For that reason it was very cheap and I had a bad transmission with a good housing so I went for it. When I took it apart little parts started falling out. Luckily, I was able to put it all back together. That was about 6 years ago and my friend's son has the car now.

I've watched many youtube videos of people rebuilding transmissions. It seems straightforward, but those guys can do it in their sleep. They know what to look for and what clearences should be and stuff like that. Not my wheelhouse. I use Dodge Caravans as my work vehicles and they drop transmissions all the time. It doesn't help that I log 50-60k miles a year. I always paid someone to do them. Less downtime, mainly.

Maybe after I retire and have more free time I might venture into tearing one down. But I'll have to have the right mindset for it, and right now it doesn't interest me that much.

Just remember to lock the cams and remove the chain tensioners 'before' you remove the flange cover, and of course that dual row bearing that you will be removing will be in great condition..

Agree completely. I understand a few folks have gotten away with it without locking the cams, and I also read that 5-chain engines are less susceptible to jumping a tooth during the process, but I don't like taking chances. I borrowed LN's official toolkit, which includes the cam-locking widget. BTW, I read the tensioners can be simply loosened instead of removed. What's your thinking about that?

Remove them, that way you know they are fully released; and be sure to mark where they came from because they are not all the same and you will need to replace their seals as well.

If I remember rightly the tension of the chains pulls the IMS off center making the reinstallation of the flange a challenge. If you are going to change the chain tensioner pads in the heads you have to remover the tensioners, so do the IMSB at the same time. By the way, in the PET they are called chain adjusters, which is handy to not confuse them with other parts that are tensioners... but I'm a minority of one who would like to adopt the Porsche nomenclature.

Or remember that the number of circles on the head of the adjuster (tensioner) is the same as the guide on the block right beside the hole where the adjuster goes.

Not everyone notices that, judging from the number of ones we find switched..............

The clutch, pressure plate, flywheel, etc. on the old engine are original, with155,293 miles on them. I might have to replace the whole works, which would cost around a thousand bucks for a quality aftermarket setup. Yikes!. Installing the new engine is like yanking a piece of yarn on a sweater. Well, in for a penny, in for a pound...

Original clutch and pressure plate? Then I'm guessing the imsb is original too. 155K miles. Not too bad.

I agree, Al. The guy I bought it from was the third owner, and as far as he knew nothing had been done to the car other than oil changes. The dual-row bearings have a 1% failure rate (compared to 8% for the single), so I guess that accounts for its longevity. However, Jake Raby said the best thing you can say about a ball-bearing unit is it hasn't failed yet, but it's only a matter of time. Something else beat it to the punch, and I'm glad it did. Otherwise, I would have missed the low-mileage engine, which are rare as white whales.

My lift table hasn't arrived yet. I was hoping it would be delivered yesterday, as I'm about to leave for Eugene for three days.

[LoneWolfGal]

Received this shipping notice today for my lift table:

"Sorry! Due to the severe snowstorm along the way, the delivery of your package has been delayed and may take longer to arrive. We will urge the courier to resume delivery as soon as possible."

D'OH! Don't they realize I can't work on that engine until I get the table?! Why, I oughta...

[LoneWolfGal]

The lift table just arrived. Now I need to assemble it. Like the engine crane, it's a heavy beast.
