Indeed, if i end up replacing the engine I may take the IMS from mine and retro fit it simply because I know its a good one ! LOL

Ach if you dont laugh you will only cry so its good to just be positive. At the end of the day its all nuts and bolts and It will get fixed, just a matter of when as its happened at a really bad time for me ! Im moving house at the weekend and start a new job in 2 weeks so its all come at once !

Keep us posted, Steve...your attitude is very refreshing. Instead of pointing fingers and "poor me" ramblings, you are attacking the problem head on and, hopefully, we'll all learn from your experience.

I have no where near the talent you possess, but I did sleep at a Holiday Inn Express recently (American joke).

Thanks all for the kind words, its nice to feel like I have some support and it makes me all the more determined to get this sorted ASAP so that I can start enjoying the car

I have already decided I will be keeping this one for 8 - 12 months then moving up to a boxster S for a bit before finally moving onwards to a nice 911 as I have ALWAYS wanted one !!

Don't be surprised if you like the Box S better, personally, I'd take a Cayman S over a 911 unless said 911 was a gt3rs.

Well,

after a busy Saturday the engine is out and mostly stripped back, but again I only had 1 day and ran out of time.

I clocked the crank and its showing 0.45mm of runout at the flywheel end which is a fair whack more than the Porsche tolerance of 0.04mm !!!

It appears that indeed I have somehow got a bent crankshaft ! its not broken but is definately bent.

Its also not the bearings causing the runout as theres not metallic residue in the oil etc either.

It does sound impossible to have bent such a tough piece of steel but the proof is now here that it can be done !

I have a new crankshaft and cradle on my watch list on eBay so hopefully will have her running sweet again very soon

If this guy can do it so can you. I have rebuilt engines from 6 to V-8's, mostly Chevy engines. My dad had an auto machine shop and I was a grease monkey by 10 years old. Engines are not hard to rebuild...all you need is the right tools, a work place and a good tech manual. Go to this guys website and see how he did it.

Cheers for the link, I have no worries about rebuilding it, my only hold up is getting the parts I need at a reasonable price but like I say, hopefully by the end of today Ill have all the parts bought and on route for reassembly !

The killer is the shipping of the crank and cradle assembly from the USA to Scotland, its over $200 due to the weight
