The comments were in relation to the poster's sentence structure and articulation, nothing to do with spelling.One of the cleverest Porsche community members I know can hardly read or write,but would embarrass nearly all of us in respect of ability and knowledge.

No, I spent time reformatting it. One of the cleverest Porsche community members I know can hardly read or write,but would embarrass nearly all of us in respect of ability and knowledge.
The content was good, so I thought people may like to read it.
Now please stop disrupting the thread with your pathetic bleating.
Oh, and it's hardly clever not to be able to read or write, lets stop glorifying laziness and ignorance.

WTF I cant believe you wrote that Globs? I wasn't even speaking to you ,just people endlessly commenting on bad grammar, moan at them,If you did write that get a life and don't tell me what I can and cant post,my pal is dyslexic not stupid that's all you patronising sanctimonious internet person.Just because some people struggle to articulate correctly on a keyUboard does mean they need slagging of and correcting mid post and made to feel stupid. I remember the effect this sort of thing once had on someone on here I'm sure we all remember how that ended,some people honestly.Just bullies nothing more.The content was good, so I thought people may like to read it.

I made someone's post more readable.Stop getting pissy about it.
Well, you can add my car to the list.
In Hartech's capable hands at the moment.being treated for bore score and a fair few upgrades at the same time.
The car's a 996 Carrera 4 (my00).
Tbh? The sense of relief that the car is going to be sorted is immense, thus quashing the porsche paranoia a bit anyway!!

Just read the excellent discussion from avi and wanted to share my very similar experience. My 2006 C4S Tip was bought as ex-demo from Porsche Wilmslow. I had previously ad a 996 Targa Tip - fabulous car. The C4S was brilliant, but I noticed that, unlike the 996, it was burning oil- almost half a litre every 2000 miles. Also noticed that there was blackening of the left exhausts - but not the right. Took the car back to Porsche who looked at it and said there was no problem. I asked them to record my concern in their system. Car continued to burn oil. Following year, took it in for annual inspection - the engineer immediately turned the car off and said there was serious knocking. Engine was removed and the diagnosis was severe scoring of bore in Cylinder 6. Porsche Wilmslow were superb - gave me a brand new Boxster S to use and kept the car for 2 weeks - completely rebuilt the engine. - new left cylinder bank, new crank shafts, cam shafts, cylinder heads, water pump oil pump - virtually new engine. Cost was £10,000+ of which Porsche paid £8,500. Since then - car has been brilliant - not burnt a drop of oil and performance brilliant. Drove it for a further 3 years, 20,000 miles with no problem. Issue with this engine is cylinder 6 - Lokasil lining of the cylinder does not tolerate the hig temperatures which are generated by the intercooler situated immediately above it. Porsche were very decent about the whole thing. However, this does seem to be a fundamental design issue
Just sold the car yesterday and replaced with new Cayman S - very cool car

You could be the first person to notice that.mollytherocker said:

You could be the first person to notice that.a) Make sure the IMS bearing gets lubed, maybe change it to a pressurised plain bearing.
b) Close the deck
c) Sort out the thermostat location and rating, and sort out the cylinder/vs/head flow rates, possibly speed up the pump.
In a water cooled engine external things influences should not matter - it's water cooled, not air cooled. Cylinder 6 gets the hottest cooling water, it's that simple. It could be however that with the marginal cooling flow that the air flow past was a significant factor, with the outside of the block acting as a radiator.
However I didn't think non turbo cars has intercoolers - do they?

I agree that the fixes would have been easy for Porsche to 'fix'. Question is, why didn't they fix them during the 11 year production?a) Make sure the IMS bearing gets lubed, maybe change it to a pressurised plain bearing.

This is what baffles me.
This issue is discussed in great detail and professorially by Hartech:

This is the most detailed description of the aetiology of the scored-bore problem. It is obviously complex (and contrary to my earlier post, not just a function of temperature) However, really worth a read

You can add me to the list as well. Engine on 1999 996 C4 just threw a piston I think. On a flatbed back to the UK as I type this.
No idea where to go or what to do. Only bought it as a runaround for the missus. Suggestions please gentlemen? Is Baz the main guy to sort these engines out once and for all?
