so I purchased this car with bottom end failure for a very good price! I soon set about dropping the engine and gearbox and stripped the engine. now just a case of organising machine work for the block and finding a good crank.



whilst it's in parts I have a little list of things to replace and also have a peek inside gearbox whilst it's off to make sure it's all ok.

welcome in the club,just did same look at my thread in C5 section,and good luck with yr project

just had a read, were did you get your crank bearings, I can only find some at tps.

wasn't easy,but in the end all engine parts were bought at the dealer

engines all stripped but have discovered the block is pretty much buggered! there are options available but the most cost effective is looking like have the engine fitted with custom liners which will enable me to use standard pistons, have a meeting at machine Shop next week to asses the job and get a quote, if pistons are no good a set of forged fcp pistons will be fitted and more than likely a set of uprated con rods.


Biggest issue is still the crank as this is beyond saving and seemingly impossible to get oversize bearings so will keep a look out for a good second hand one if not I may have to have a forged one made, none of this is cheap but I think worthwhile as the car is probably never gonna be sold, I have thought about a second hand engine but at around 3.5k I cant warrant spending that for it to risk blowing up 6 months later.


plans next week after meeting will be to strip and inspect box which on removing sump seems nothing untoward so fingers crossed there, turbos been sent of for a refurb whilst its stripped as no point refitting the old ones as all though they seem good condition I don't want a failure on a new engine.


whilst all this is happening ill get on with cleaning everything up and checking parts as follows


1 I have injectors flow tested and cleaned

2 turbos reconned

3source decat pipes and exhaust

4 possibly send blistein coilovers away for a service

that little lot should keep me busy

Welcome and good luck with the project! If you have a look on the C5 forum there's plenty info on recommended/essential bits to change and things to check whilst the engine is out.

every single thing will be checked and replaced of needed, however sourcing a crankshaft is seemingly impossible, if one cant be sourced it will end up being broke for parts. so projections on hold till one turns up.

small update good second hand crank sourced and en route, so once its arrived its off to the machine Shop!

Excellent news. Where'd you source it from in the end?

stumbled across one on Facebook of a guy, I've been reliably informed a s6 crank is identical too just need to use a different flex plate.

bit of a update ended up bagging a complete engine for a bargain price that had been removed for being down on compression on 1 cylinder ( was bought for parts) and turns out it only needs a valve bottom end is in perfect condition!

work has started to clean and refurb the heads and during this week will strip gearbox as a precaution and have a peek inside to see if needs anything.

ordered this twin afr gauge today as well one the most important external gauges you can have IMHO to keep a eye on your engines well being.

pass of bits ordered today from tps, and one of the heads stripped will get some pics this week.

heads 1 stripped and quick clean ready for work
