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.

no updates on this?

flouese · 03-17-2018, 07:41 AM

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.

Cunningr · 03-17-2018, 09:19 AM

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

Cunningr · 03-18-2018, 09:14 AM

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.

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!

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?
