[vipola]

Damn this is very sad to read.. :/
Any way you can get back to the seller because he hidded something??

Tell yourself at least you have the advantage of having a good mecanic background and been able to do some work youself.. imagin the bill if you had it tow fo the dealer and pay them to investigate all that..

SS
Just be very aware that these M96 engines are very complex pieces of kit - more so than the straight 6 Nissan units.
Before embarking on a teardown, I would suggest you obtain as much info as you can on the complexities / costs / tools etc you are going to need campared to (say) going to Porsch specialists like Hartech or Autofarm for advice.
Whichever way you go, best of luck & keep us informed of the results.....

Cheers Steve,

I'm aware there complex but not as complex as some of the stuff I have rebuilt

Rebuilt some Rotarys along with upgrades at the same time also done a Mitsi V6 Mivec engine recently and I have rebuilt gas turbines and various other mechanical/electrical systems through my line of work too so the wee boxxer engine is a piece of cake in comparison

Plus I also have the full workshop manual to hand too

Also have all tools that I will need which I have collected over the last few years of messing about with all manner of engines/vehicles.

There was me thinking now that Im an Instrument Tech to trade I would no longer be getting my hands oily ! grrrr LOL

Dont have any comeback with the seller as it was a private sale and sold as seen. On the test drive the car drove fine, although I didnt give it quite as much abuse as I probably should have !!!

My own fault though, and to be honest I actually believe the seller had no idea there were any issues as he was the type of guy who would probably only ever drive below 4000 rpm !!! LOL

SS you're a saint, why? Well I for one think the PO knew exactly what was wrong with that automobile. Sounds like you have an impressive resume to tear down a m96. I would however, heed Steve Tinker's advise as I have read where even full-time mechanics would have a hard time with the M96. Good luck, we will certainly be pulling for you to resurrect the Boxster.

Cheers dude,

I do genuinely believe the guy I got the car from was unaware, believe me I have bought some seriously rough cars in the past deliberatly to fix up and sell on as I enjoy doing so and you can get a feel for people. This guy was 100% clueless about cars other than that he knew how to drive one LOL There are even receipts for having a wiper blade replaced so basically anytime this car needed something done, it went off to a garage and he payed silly amounts for it to be put right.

Thats aside though, theres no point in being angry about it, At the end of the day I have bought a well optioned boxster for about £3000 less than the current UK market value, so even at worst if I did source a full engine and drop that In I still theoretically wont be out of pocket other than for my time involved to sort it.

But that would be the easy way out ! I never jump to replacing a full engine until I know exactly what failed.

I once bought a car which had a suspected blown engine which on full investigation turned out to be some bad wiring and a small oil leak !

Cost to fix ----- £10 whereas anyone else would have replaced the engine and it would have cost ££££'s

This M96 failure though is a bit of a special one from what I can see so far, in that the failure has not been noted before anywhere I can see online. I have been in contact with flat6innovations and Jake is keen for me to keep him updated on my findings as he has not even had one of these engines with these sort of symptoms.

on the plus side .... my IMS appears to be in perfect condition !! haha !

[eightsandaces]

Well SS, god bless you and your positivity, it's very refreshing. Besides, you have a failed engine that isn't because of an IMS, we love you just for that!

[Sideways Steve]

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 !
