Bore scoring on the 981? - Page 2 - Boxster/Cayman - PistonHeads UK

Came across this yesterday: https://rennlist.com/forums/987-981-forum/1091142-... A bit worrying. Any other cases ?

I have a base 981, same problem and engine was only 12k miles old - new engine was supplied and fitted in Austria (was doing a road trip when it went), very glad it was under warranty..

Surely if the engine went at 12K miles they would sort it even if it wasn't under warranty, if it has been serviced on time and especially by Porsche. A friends Aston V8VS blew up at 30K miles on the clock and on track......Aston coughed up a large amount.

If you read right through the thread it does look like there were a number of prior issues (eg coil replacements) which might be the root cause of the failure. It doesn't look an isolated issue, but not something that owners ought to be paranoid about.

A couple of things that seem important mentioned in looking after the 9A1 engine or any performance engine are regular oil changes , quality petrol and warming up properly! But you are always going to get a random failure in the modern manufacturing process. A couple of years ago talking to aPorsche technician said this was true of the 9A1 engine no real design issues just random faults like they had a problem with a 997gts which turned out to be a poorly made injector. In the long term when those motors get to high miles and need an engine refresh or you are thinking about increasing cc then nikasil liners would seem to be the way to go

Interesting how Porsches in USA have 10k oil change intervals according to one of the posts

I’m not the only loitering and curious 86/BRZ owner here I see! Love the Cayman, principally the middle engine and NA F6 really appeals. Didn’t know the 987.2 got the 9A1 engine - duly noted for any purchase considerations in years to come. Happily remain in full honeymoon period with BRZ. The only ennui is the gear ING; will have to suck a see one day

More cases: https://www.planet-9.com/threads/engine-replacemen... Pretty solid argument for that warranty extension...?

how does one even check if they have it? tell tale signs ?

I think it's down the the really poor-quality fuel they have in the US, honestly. Seems to kill their injectors, which leads to bore washing.

Seem to recall BMW had a problem back in the 90s with fuel quality and bores and ended up switching liners

Next thing we know, the 718 will start getting it to

Just checked-out a 981.2 for a friend. Being offered (with CPO) by a Porsche dealer, 30k miles but sounds horrid on tick-over. Sent a sound file to a reputable engine shop, and they confirmed bore scoring. No record of any oil changes over a 2 year/20k mile period, that probably doesn’t help.

A model of car that doesn't exist has bore scoring diagnosed without actually looking inside the engine...

Haha...some Indies even struggle to diagnose bore score accurately with the engine right beside them with a bore scope shoved up it...

Only need to hear it once and you'll know instantly next time.

Would still like to know what a 981.2 is?

So to sum up, a 981.2 with 30k on the clock with FSH is being being sold by a Porsche OPC with full 24 month warranty with an engine that sounds horrid on tick-over, is that what you are saying?

I have been on here a while, it has never been any different, I see these forums as a Circus that can be both informative and entertaining, but you have to accept there will always be some Clowns on here telling 'stories', it is part of the show

I watched a recent talk given by Hartech, organised by PCGB, and Baz was saying that bore scoring is often diagnosed when there is none. Some indies see the slightest marks on a liner and jump straight in with an incorrect diagnosis. It’s much, much rarer than the internet would have us believe.

Scoring is misdiagnosed and you need to be careful who you ask to scope an engine, yes. But on certain engine types (eg 3.4-plus M97) it's utterly epidemic and the only rarity is that it's a rare example of an internet scare that's actually true.
