PostPosted: Wed Dec 06, 2017 3:00 am    Post subject: Bore Scoring - how much is "normal"?! Looking to r Reply with quote

Hi all,

Im a former 996 owner (engine blew, cylinder liner cracked), and a year has passed now with every car ive had since has not stopped that need for another 911.

Reason I didnt get a 997.1 C2S last year was for obvious reasons. My 435i M Sport Plus has nothing on my old 911!!!!

Now though, hindsight and all, im looking at the 911 Very Happy

Ive been sent some borescope pictures of a car, im a dab hand with cars and tinkering all the time on my track car. Ive never looked at bore score though. How much is normal operation - if any!

Ill try and figure out how to upload images if anyone here can assist please?

Many thanks in advance,

Andy

normal for a 997.1 .... but do you want to be the owner that drops £££ on a rebuild sooner or later?

I would get one without any score evidence or let someone else take the rebuild hit.

Unless its cheap enough to take the risk.

You can get some minor grazing on the liners but those are definitely scored. It'd be worth buying if you could get it £10k less than the price of a similar car, otherwise walk.

Hi all,

Thanks for your feedback, I’ll walk from this one Sad gutting as it’s the exact spec. It’s on the money so I may see if they will factor in new linings at hartec to the price Wink

Hunt probably continues

Thanks

Andy

Ask Baz at Hartech, though doesn't look good.

Is it a seller on here or a dealer or something else? Would be nice if you shared where the car is so someone else doesn't get taken in........

Andy mate , good to hear your back and looking mate but that ones a NO thats not normal wear thats quite bad scoring, normal wear would be more even and mild more like scratch marks not actual groves .

As you know most must haves can be retrofitted so buy on condition and that alone .

Don't forget the 3.6 manual 977.1 has a stronger engine so don't discount it they are great cars. and a few grand on mods and its faster than a stock 3.8 Thumb Thumb

if you could get the car in the score pics for £14k and Hartech rebuild 10k you would have a bullet proof car for mid 20k also call Baz at Hartech and see if they have any rebuilt cars for sale now or soon. Thumb

Thanks everyone, I really appreciate the help and advice! the company with this C2S sport chrono have a sister company (perfect touch?!?) who can apparently fit Hartech liners and do the rebuild..... I’m very dubious and would rather buy a better car from a more reputable dealer. I’ve found a few from specialists but they are non sport Chrono. However have the other options I want and low miles for the money.

I will go look at some when I’m back in the uk and see what’s what.

Haha thanks Phil, starting with Throttle bodies eh 😉

With mild scratches, is it a case of it will need a rebuild in the future. Or with regular love and lots of oil changes it can be maintained and not made much worse.

Many thanks and look forward to returning to the family 😀

Not sure I would rate those as minor scratches!!!

Definately ask Baz to look at them. I don't think I would go to anyone else for advice about bore scoring.........

Would the dealer pay for a rebuild depending on Baz's advice? Would be a great car if it's rebuilt and sorted out now....

Nothing deep but plenty of pick up there .

Hi Andy, Floor yep Throttle body plenum 200 cell cats and a remap your sorted lol.
It really takes a specialist to identify whats borescope and whats regular bore scuff that you would find on any car, the later is quite normal and not just Porsches get it. yes 10k oil changes use millers 10W50, warm the engine before going over 3k revs , LTT etc etc those are the normal things .

do have a word with Harlech and see if they have any rebuilt cars coming up for sale, and give some thought to the 3.6 cars generally a bit cheaper , probably been driven steadily , and you would get a newer one with the newer IMS for your budget. Thumb keep us posted on progress mate. Thumb

Just to confirm the only people who fit our liners are us. We have invested in hugely expensive modern machinery to do it and have highly trained staff that enable the quality to make it all work so successfully.

We are happy to fit our liners to owners or other specialists crankcases, or engines, or of course - cars but we do not sell our liners.

This is entirely because the process of making the liners is not as difficult as machining the crankcases to fit them correctly and most engine re-manufacturers do not have equipment that is capable of creating the right tolerances (especially on depth shoulders) nor can circular interpolate steps (which is essential) and only an accurate CNC machine can re-create viably.

We do have a business in Canada that we are working with who have machine shop capability and we are developing their ability to recreate our work here - over there - but it is highly specialised and takes a lot of time, effort, special jigs and tools.

As far as I am aware we are also the only supplier that truly converts the cylinder to a true closed deck construction (many others claim to but do not actually fit the top of the liner to a precision machined recess in the block).

Although most customers now have all 6 cylinders replaced we still are prepared to replace only damaged cylinders and can fit support rings to the others to prevent them cracking one day.

Classic bore scoring but not as deep as it will probably become later.
