Engine rebuild

Rebuild:
Take one broken engine, fiddle around a bit, bake for 20 mins at gas mark 8, pull new engine out of oven and serve with side salad.
Or the short version:
Engine broke. Take apart. Fix.
splsward, take no notice he's just had a baby!
BTW which part of re & build did you have a problem with?

Chill Dude, just a bit of harmless fun.
Engine rebuild, can be partial or complete, depends on diagnosed problem - similar to surgery?
(I am Consultant Gynae/Obs on-call tonight - what you do?)
Total rebuild will require engine out with complete stripping and replacement of all worn parts, usual also for bottom end rebuild eg for bearings, crank shaft etc. Top end usually means for cams, valves and head, in many cars can be with block left in situ, inc. AJP 8 in Cerbera, BUT NOT for the Speed 6 which has to be removed - DoH! (see profile)
Engine out - mucho dinero in labour.

Simple question: what is involved in a rebuild?
All I'm after is a bit of detail.
Sarcastic twaddle is all very well but I can't honestly be bothered.
Thanks.
Here's an idea
.. instead of asking on here why not ask the people who actually did the rebuild...?joospeed said:

Exactly !! We dont have crystal balls.
You have an engine, it broke, it needed work, they fixed it !! IF the rebuild was a long while ago I wouldnt even think about what they did, it is irrelevant?
Sorry....one too many pints of ol' wife-beater last night obviously had me fired up.
It may seem a daft question in the cold light of day but the phrase 'engine rebuild' doesn't mean very much other than taking an engine apart and...erm...putting it back together again. I can understand that for the likes of an F1 team rebuilding an engine after each race means they can ensure every part of the engine is in top notch blueprint condition. For my car, and countless others I read about on here it appears to be a chuck away phrase meaning 'your engine doesn't work so we'll take it apart at great cost and maybe fix things as we go'.
So....generally speaking...what bit of the AJP V8 usually goes belly up requiring said rebuild? When rebuilding do the other components in good working order but perhaps a little worn get replaced/refreshed?
If I come to sell mine in the future is the fact it has had a rebuild a good or bad thing?
Comedy replies and flippancy welcome!!!

A RECENT rebuild is a good thing. 2 or 3 yrs ago is irrelevant(ish).
A rebuild is normally top end stuff but can be pistons, heads, crank etc My rebuild was everything bar the crank thanks to some bodging by someone prior to my purchase.
If the cost is under £3K then it is minorish stuff.

In typical TVR fashion I ended up with a complete top end re-build at 9k miles on a 2001 car. Top end was totally written off as un-repairable. (Previous owners 
) Heads.. Cams.. timing chain and tensioner etc, etc, all knackered.
In the end (4 very long months later) I ended up with a complete RR rebuild. Total cost..... A LOT! Luckily vendor picked up most of the tab

The V8 heads are a mess, many issues, but they tend to hold it together for a while, but when they go, its a write-off at the top end I'm afraid!.... so just like race-cars, after every race they get a rebuild... everytime you take her out for a spin... pop into uncle bobs overnight ringer garage, and get the front end swapped...

Peninsula TVR.... I ended up going down there in person to check the car was actually still there 
(not anywhere else as it was already 3 1/2 months into the repair) and in the end had to demand the car back.
I must have heard every! excuse going. Got parts then not. Didn't fit but getting more, TVR delivery didn't come, Delivery truck failed MOT (On the day the car was going to be delivered back to me....Twice!).
Still only had the car back since Nov 04 and since then it's developed a Antifreeze leak (Bottom Pipe just behind front bumper) and a power steering fluid leak.
Oh... and for some reason the air conditioning drive belt has snapped!!!!
OH and to top it all of some Chap (
) drove up the back of me on Tuesday.
Thames Valley Racetech are putting a quote together for me, but whilst I was there we found that the air-boxes were not fitted correctly and Jubilee Clips had been used to secure the pipes to the boxes and an overzelous engineer has CRUSHED the mounting spigots on the air-boxes themselves.
Other than that Cerbera ownership is going well :-)

Well, I bought my cerb mainly because it just HAD a full engine rebuild!!! Quite simply, if the engine has recently been fully stripped, inspected and rebuilt with all worn parts replaced then effectively you can consider it to be a 'new' engine. Furthermore you can expect that the latest components have been used, e.g. new crank, new cams etc so in theory the engine should be tougher than it ever was........ But in answer to your question, as I understand it all AJP V8s to come through the dealer network for rebuilds go back to TVR in Blackpool, and I have an extensive parts list for my rebuild, so as Joolz says, if you really want to know what was replaced on your engine, the engine department at TVR may still have the records - just call them with your engine no.
At least if you own the car immediately post re-build, fingers crossed, if you treat it properly i.e. allow a generous warm up time... keep all essential fluids topped up and drive her with 'mechanical sympathy' then you should in theory enjoy a good few years of trouble free Cerb ownership (less the usual niggles). I really wouldn't like having a car with 30k+ miles and no rebuild, as you just don't know what unseen damage some less 'mechanically sympathetic' owners may have caused............
'Mechanical Sympathy'!!! Anyone guess I used to be an engineer!!!!!!!!!!

the cylinder chamber loading is quite high in the V8's, the 'cheap' liners (I am using this term lightly!) tend to get hammered... but still the engine manages to keep it together... but the top end, the valve seats soften up and chew inwards, reducing the port sizes and then the guides themself wearing out... eventually leading to a SERIOUS top end problem... but usually you're lucky and the timing chain snaps on ya which leads to a top end rebuild anyway... and tends to be a little easier to hack well, depending when she snaps, but usually the chain snaps when you start her up and the torque pull just does it for her... on the move at 80+, I think a new engine will be a safer bet... its a flatplane engine, the stress/vibration of these style engines is fair bit more than traditional crossover setups, whence why most companies including the yanks stick to crossovers for roads... its a rare thing, seeing a flatplane engine in a production car, ferraris and a few other exotics maybe, but look at their engine rebuild frequency and costs!... a cerbera, tends to work out a lot cheaper... and holds it together a lot longer... just dont wait till she splutters her guts out... preventative = less headache! IMO...
Not sure I would look favourably on a rebuilt engine. I would prefer a good sounding old engine. I don't think a rebuilt engine gives you any reassurance, any more than a new car is less likely to break down than an old one.
I think you have made the assumption that all the AJP engines are on their way to a rebuild.
I think AJP engines are a 'one off'. The production is no good enough on quality control. That leaves you with some good and some poor engines comming off the production line.
What you've got to ask yourself is, did they find the cause of my last engine failure when they did the rebuild. Fair enough if you think the last pilot was the cause, but if not you could well have a rebuilt engine with a still undiscovered engine fault ready to give you hassle a few thousand miles down the road.
If you read these lists enough I suggest my argument is backed up by the serial rebuilds that some people have had compared with the high milers.

Julians got a point... always a pattern seems to be lurking around the 'problematic' ones... ie. daggarts cerbera... (poor bugger)
