Yeh, sorry, that was more like my dream. ?

Audi R8

Just standard

So just out in the garage with my new honing tool and just as i go to do this cylinder i notice these huge scores. I'm guessing i either need to get a new block or get these professionally done larger then get pistons to match. Whats everyone thoughts ? The grooves that are clearly visible can be felt with my nail as i rub them across the surface.

Just cleaned the block myself and degreased everything. New honing tool arrived so i'll give the cylinders a scrape shortly too.

Nothing new done today but i bit of news from Midland Turbos who now have my turbos. They are rebuilding them again at a cost of £185 per turbo with new bearings and then a re balancing. Also just dropped a £1K order into conceptz to start my engine build off in a few weeks.

I'll send the turbos down to Midland again to be sure.

I was thinking about that, get it shot blasted too as there is a fair amount of surface rust on the bottom.

Gone is the silver paint to reveal a few rust spots on the sump. Need to get a wire brush to this now then give it a coat of black.

Next job was to strip the oil pan as it was also caked in silver paint.

Cant believe how long this took me and i used a combination of gunk de-greaser, wd40 and brake cleaner. Extra luck that the de-greaser was strong enough to strip paint too so all the silver that was only the block came off. When everything was dry again i used high temperature paint to coat the sides of the block and top to make it look new.

Block now stripped again and de-greased. Also stripped off all that nasty silver paint which was like a layer cake.

The cranks only back in to protect it. Things have a habit of breaking or falling off shelves in my house. At the moment the crank is back out and I've stripped the paint off and degreased everything. Just need to hoan out the cylinders when the tool arrives to do it. Update shortly.

They were rebuilt by midland turbos and not me. I simply dismantled them to clean the oil ways and reassemble afterwards.

So i want to clean my block properly as i want to be 100% sure that there is no contamination inside. What i know and wont do is the obvious method you see all over youtube with people using a jetty and hosing it down. Trying to do this DIY as much as possible for the moment. Below is a quick video of the block, i'd like to strip off all the silver paint and degrease the full thing. Whats the best solution without the chances of using the block by using water. As you can see the crank is turning nice and smooth at the moment and i really dont want to upset that.

I didnt this time as they were done not that long ago and i ensured everything was put back together the way it was. This rebuild was more so to clean everything and ensure no nasty metal particles were inside.

Tell me about it, the larger ones are like playing Russian Roulette . And i done them with needle nose pliers

Are you sure it's the abs pump! Do you have a bose system as my zed has an amp under the plastics just behind the ABS area. Just a thought.

After the oil got contaminated and slightly washed down with fuel the turbos also ceased up. I decided to strip them and do the rebuild myself as the costs for that at the moment to be done professionally are just too much. Here the first one is stripped down. Took me most of the day to clean these but using an air gun, wd40 and a can brake cleaner i got them to near new condition again. On assembly i used fresh oil to lubricate the bearings and everything fitted together again perfectly. I now have two turbos with freely spinning shafts and propellers.

Heads stripped down and cleaned.

Not posted on my build thread for a few months so i thought i'd recap and move on. So here goes : Back in 2015 my purple zed was written off when it was hit by truck on the m42 while on-route to the NEC car show. It was hit after i already broke down due to engine failure and pulled into the hard shoulder to get assistance from the RAC, Luckily the insurance paid out an agreed valuation and the current project started. The new build which was called the MKII was a more prestige build and the final thing to be done was the engine. I had an the engine rebuilt with forged pistons, up-rated injectors and also a new ECU to boot it all. Unfortunately i was dumb enough to reuse the polished plenum from the previous engine that failed without thoroughly giving it a deep clean. In the end some fragments of the damaged previous engine made its way into the current engine and was only discovered on the day that the zed was trailered up to get a mapping session. Apart from a few unrelated starting issues the route end cause of the new build failing was due to filaments from the old pistons that blew-up. Where i am now is that i once again have to rebuilt the engine from scratch; but this time everything has to be scrubbed clean to make sure that no contamination of the previous engine has got into the new engine. The engine has once again been removed, stripped to the block and the cleaning process has begun. I'll upload a few pics to show the process shortly.

Before i dismantled them the spindles were very tough to rotate but after being cleaned and oiled up they spin freely enough and the blades also have no signs of damage.

Time to change things and now the theme is Engine Bay Only. Get a nice engine bay pic uploaded now.
