Wonder if any body could help
Went for a drive last night, nice sunny evening not going mad but fairly brisk on some quiet a roads and a 10 run up a dual carriageway. Car was feeling nice.
I was going down a road and changed from 3 to 4 and then no power. Engine check light came on and the engine sounded really rough and felt like it had about 50 hp. I mused it about 2 miles then it stopped and would not start. No evidence of loss of oil but did not notice smoke as it was dark.i had roof down and thought if it had blown up, I would have smelt it ??
Anyway, when I turned it over it sounded very odd, almost as if it was turning over quicker , very different noise almost like there was a spark plug or two missing.
Help!!???'!!!

Faster cranking speed can be the result of a loss of compression.

I would get it checked out asap and not attempt to start it again.

I won't try to start it again. Thank you for replies. The oil is normal level and still got coolant. It was absolutely fine one second and then not the next

If it sounded like ball bearings in a tin, then its likely the IMS.

Sorry mate, thats a stter. Get it to a good specialist for a look at.

Hartech are the daddies of course, but you are not far off Sports and Classic at Knutsford.

Circa 4-5k from what I remember reading....Link has all options...

(d) Typical bottom end rebuilt for exchange as
above but also having one liner replaced, Boxsters
around £2300, 911’s (including the other 5 bores
re-rounded with support rings), around £2600.

(e) Engine exchange (not removed, fitted or
running) Full rebuild for Boxsters (including new
intermediate shaft bearing and spindle, chains,
gaskets , seals de-coked etc) around £3500, 911’s
(as Boxsters but also including re-rounded bores
and support rings) around £3900.

(f) As (e) above exchange engine (not removed,
fitted or running) but including a replaced cylinder
liner, Boxsters around £3950, 911’s (including the
other 5

Probably just worth selling as a non runner or for parts then. Real pity as we had just put mo30 kit on and new performance friction bell mounted brakes.

What year is it? As you say, its probably written it off, but keep all of your options open. What about a secondhand engine?

Damn Porsche for this! Its really frustrates me and I don't own one!

Ok, so a late 986. Not an easy decision. A 996 engine will fit of course, but it makes little sense.

Its basically the same M96 engine with all of the same risks.

I hadn't realised they were all so fragile. Are 997 engines weak as well?

An engine seems to be around the £2.5k mark

I hope it's not considered terminal. My 'S' is the same reg with 85k on it. Had minor service 500 miles ago. Hoping I'm not on borrowed time. eek

This is a story from 2006....

http://www.autoblog.com/2006/11/20/porsche-produce...

200,000 Boxster up till then, I'm guessing most of which, with this potential IMS issue.

Of course being PH'ers we hear about more IMS issues than most, but I wonder how many have gone out of that figure?

Wow soooooo much IMS paranoia here it's a wonder some folk even put the key in the ignition just in case of catastrophic engine failure which will also probably lead to a fire, burn your house down and kill all the neighbours. At least let the guy visit a mechanic before we write his car off.

I know it doesn't sound good but there are loads of other less terminal posibilities.

My boxster started to sound very sick and went very lumpy with lots of warning lights on my last track day. Instead of taking it to the breakers yard a visit to a specialist diagnosed a badly fitted manifold, so fingers crossed for you matey it's not the dreaded IMS
