Flashing CEL, pulled over, car towed. Initial reports from indy repair "engine seized"! Please say it isn't so. Had oil and IMS replace 10K miles ago...
Anyone looking for a roller if report is accurate???

Ouch! that doesn't sound good. What were the symptoms? Noises, smoke, grinding, fluids pouring out? I imagine if the engine was seized you would have experienced something of significance besides just a flashing cell.

No symptoms, no noise, no warning. Slowed down to pull into a gas station to fill up, flashing CEL came on, turned the car off but made a mistake and tried to restart and all I got was a click then nothing.

A little out of my neighborhood for a roller.

Man, it sounds GRIM!:barf:

Tell us a little about what the situation was before it died, oil level? Before you bail, get an estimate for a replacement engine. I've done one, it is within the capability of a good shade tree mechanic. Motivation is a real consideration. Just finished mine, sort of. I've done Toyota, Ford, & Dodge engines in the past, the Porsche was a whole 'nuther country. Most difficult I've done to date, not impossible, but a lot of little puzzles.

Ah feel yer pain!

Brian: all fluid levels were fine. Car ran started fine, no issues. Nothing out of the ordinary that would have caused me any alarm. I was able to source a 2.5L w/84K for $2,900. Not sure if remove/replace is in my skill set. I've pulled the engine on my 66 912 several times, but the 986 just looks scary. With help, I could do it. My only other concern would be getting the electronics to talk to the engine. My knowledge of DC voltage stops at the on/off switch.

Sorry to hear this. How many miles?

It sounds like it's in your skill set. I put an engine with 02, manual transmission wiring and vacuum lines in my 01 with tiptronic. Required removing the wiring from the old engine and putting it on the replacement--no fancy electronic knowledge needed, and vacuum isn't that different. I'm retired and I took my time, taking notes as you work is imperative because it pretty much must be reinstalled in the same order you took it our. Everything can be done by a 66 year old man with arthritic shoulders and neck.

My replacement engine is a used factory re-manufactured engine with an updated IMS bearing--shipped from LA to Tucson, it was about $2500 total.

I used an air jack, taller jackstands, and a cherry picker to lower the engine and trannie to an enlarged furniture dolly. I have a Hitachi 18v cordless impact that helped a lot and a set of ratcheting box end wrenches. I also have an air impact. The common socket sizes are 10, 13, & 15 mm, and whatever the axle nuts & pulley nuts are.

My "while I have it out" list include motor mount, new tubes & spark plugs, rear main seal, front main seal, water pump, underdrive pulley, & new belt. Spin on oil filter & magnetic plug. You might also consider a replacement IMS bearing which can be done from the rear outside of the engine. And I cleaned, greased, and installed new cv boots.

I am enjoying the sense of accomplishment and the pride of "I made this" ownership.

Everything you might need to know is available by search. LMK, I'd be willing to mentor if you like.:dance:

You've inspired me. I am 62, not retired (I do not have permission from my wife yet). I have all the requisite tools, less taller jack stands but I can make something tall and stable enough. My current motor has 171+k miles on it, so it probably is tired. I don't want to let go of this car, so I might give it a whirl. There is more than likely enough folks here that can bail me out via this forum if I find my self in trouble. I became one with my 912 the first time I did a complete rebuild on its motor, so why not have the same experience with this one. Thanks for the encouragement. I'm going for it. BTW where did you source your engine from?

Before tracking down a replacement engine, are you sure your current motor is really toast? There have been plenty of instances where the mechanic said to replace when all that was needed was an AOS. Think I'd be absolutely, positively sure before dropping a bunch of money on something you might not need.

2nd, if you do need to replace the motor, the Bentley manual has plenty of info on how to remove / replace an engine.

3rd, is there a back story to your current engine? Were there issues when you replaced your IMS, like possible metal shavings floating around? I don't have the best memory anymore, but seem to recall something like this with a member a few yrs back. Would be good info for the community.

Good! I did mine completely by myself, btw, no one helped me.

Here's the source of my engine. My experience with him (so far) is that he's pretty much on the up & up. I got a used top (w/ frame) from him, too. I picked mine up at the Fedex LTL dock so it was pretty reasonable shipping.

BTW, the air jack & the tall jackstands (6 ton) are available at Harbor Freight and are definitely worth having.

Good sentiment. But his engine does have 171k miles or so--which is like 500,000 in Toyota miles. Or 250,000 in 96 Dodge Dakota miles. Probably past it's pull date.;)

I'd pull the plugs out and try to turn it over before planning the burial.

Guess I missed that leading 1.

How inspired can you get?

You did pretty well at 170k+ miles. And it may not be a toasted motor but something that could be fixed
But spending $$$ on a 18-19 year old 170k+ mile motor doesn't make much sense either

So it just hit me , you replaced the IMSB at 161k miles. How much did that cost?
At what point mileage wise(110k, 120k) is it just not worth replacing the bearing. I would think at 161k it's not worth disturbing it especially since it is a dual row bearing
If it was my car I would want to know it wasn't the replacement IMSB after 10k miles

Given the circumstances and recent IMS replacement (and cost to do so), this is possibly the worst failure story I have read; I am very sorry for your loss. Given that, please verify failure, and if is really dead, please do (or have done) a through autopsy. The cause of this failure would be of great interest to everyone in this community...not to sound grim or glib, but your loss could save another.

Best wishes and hoping for the best outcome.

Regarding the IMS replacement, I had it done at 163K miles while the clutch was being replaced. Did not have a thorough history of the car so I took the safe route.

This is the exact engine I am currently looking at if in fact my motor is toast. The only issue with this one is it still has the original IMS. If I do get this engine, I will replace the IMS.

Hard to believe an engine would completely seize dead with no warning of any kind. I'm with the others, pull plugs, check AOS. There was a woman on this or another forum had similar issues. AOS died, dumped oil and all she needed was to clean out the offending cylinder, put the plugs back in, start it up and burn off the residue. Good to go.

I'm with Husker and Geof3, check the AOS and see if it dumped oil down the intake. It's free to check

When an engine seizes it makes a very characteristic noise, kind of a squeak. Did you hear that?

Exactly, like a nasty squeal, it's pretty obvious and doesn't sound good at all. And the engine dies with a pretty good death throw. (clunk)

Like many others have said, you need to do more problem determination before writing off your engine! Have your mechanic follow the advice here and in other threads. Check out the lady with the AOS problem and other similar threads.

Best wishes for a good result.

One other thing. You are going to need to make sure your mechanic is a stand up guy. It would be easy to take advantage of a situation like this. It would also be helpful if the shop worked on A LOT of Porsche cars.

I’ll also add +1 on the AOS. When that failed on my mom’s 987, it wouldn’t crank and couldn’t even be bump started. Pulled the plugs, intake, and got a lot of oil out. After the oil was cleaned out (and changed) with a new AOS it’s been fine since.

Crankshaft position sensor.

He's done right by me.

Did you find anything about your old engine? A blasted AOS wouldn't provide enough oil to hydrolock the engine while it was running down the road--and there would be a huge cloud of smoke out the tail pipe. :barf:

no updates on this?

Just got a call this morning from the repair shop. They pulled the oil filter and it was "full" of metal pieces. I decided not to got further with the investigation to determine if it was the IMS or other parts. Time to source a new motor. Looking at:

https://www.ebay.com/itm/Porsche-986-Boxster-Complete-Engine-Motor-2-5-2-5L-84k-Miles-M96-20-IMS-UPDATED/263021815320?fits=Year%3A1999%7CMake%3APorsche%7CM odel%3ABoxster&epid=2002468421&hash=item3d3d526618 :g:Lc8AAOSwv~1aDInA&vxp=mtr

$3K or best offer. Any suggestions on a best offer?

Sorry to hear that its toast. Bummer.

With only 84K miles and the IMS done, I'd offer $2600 and see what they say. $2750 is about the going price, but even if you had to pay the full $3K you're still not getting a bad deal.

Sorry to hear about the motor. Have you considered doning the 3.4l swapp? Since you have to put a motor in oppurtunity knocks! Lol

Is a 2.5L to 3.4L possible for a 99 with manual transmission without too many additional modifications and expense?

You'll be lucky to find a 3.4 for under $5000. I have one in my boxster and love it

Looked at the eBay ad. Does Porsche sell 'factory' IMSs? Thought aftermarket were the only options these days

Well it appears doable probably not cheap, but then again you would have a hot engine fir a sweet ride. I found instructions that can give you an idea of what is required.

http://carltonbale.com/wp-content/uploads/2006/11/porsche_boxster_3.4L_engine_swap.pdf

It has free shipping, from CA to FL, that's probably worth 4 or 5 hundred. So at $3000, it's not a bad deal if the engine is okay. Figure anothe $2 grand or so to have the engines swapped or, as we previously discussed, you can do it yourself. I did mine, and so far it's okay.

I plan on doing the swap at home, with help in between the overhaul of my 66 912 which is already in progress.

My brother had a 67 912, got it for $1200 & $10000 later (professionally rebuilt engine) he sold it for $20K.

You can do it. If you need moral support or "blind leading the blind" help & tips, PM me. I recently finished installing a 2.7 l in my '01. It is a puzzle and an adventure!:D

Thanks for the encouragement. I plan on using the full resources of the pool of knowledge on this board to help me through the project. Stand by...

Based on what the repair shop told me "oil filter is full of metal chunks", and the engine is seized, I will assume the IMS let go. If that's the case, does this affect any other systems, i.e. transmission or other components. Will I need to do anything besides remove/replace the motor?
