Audi S8 5.2 Vqp

Hi, I’m new to this forum I’d like to introduce myself.

I purchased my Audi S8 5.2 V10 over 3 years ago as a project. It was sat in a barn since 2009. It’s a 2007 model. It has covered 4800miles so been of the rd a very long time.

Initially I bought the car as a non runner. The front end was in the boot and interior was in pieces although everything was there.
The previous guys were chading down a supposed electrical fault and had replaced the steering column from ebay. These cars only allow a new column to be coded from the main dealer once as they are virgin.
Do cut a long story short I purchased a column from audi to the tune of 1200pounds and went on my mission of repairing this beauty.

So after hour and hours of trying to figure it out in purchased odis and have since managed to code the column and get the ignition on. Thank God.

As it hadn’t been started in over 10 years, I did a piston soak for a week with marvels mystery oil which was poured through the spark plug hole and left for a week, then turned it over by hand, whilst draining the oil around a litre of water also came out of the drain then the remaining oil. I changed the filter added new oil before any attempts were made to start her…

bearing in mind, I couldn’t take the car anywhere because it was in pieces. I havent driven the car.

Now 2 years on fresh oil /filter and fuel filter the car has been sat and having started the car over 10 times leaving it running for hours on end to warm up everything ( I still havent driven it).

I decided to remove the sump and clean the oil pick up. This is what I’ve found.

Sludge in the bottom of oil pan. Lots of it. Luckily it only stayed at the bottom of the pan ( well I hope it has.)

The oil pick up pipe was blocked 99%.

After cleaning it with degreaser .20200517_040627.thumb.jpg.48b1622400c1eb8f6fdf2303593ae97c.jpg20200517_040612.thumb.jpg.df4933982dc72467c2237d4bda197883.jpg

I also took a snap of the engine bottom end, looks very clean in my opinion. 20200517_042158.thumb.jpg.d156d1f65a838536ec0d22d87b88cf77.jpg

I installed the oil strainer and sump pan with the help of a workshop manuals from awesome site .

Sealed the pan using loctite 5980 black silicone and filled her up with quantum 5w30 from the audi parts dealership (TPS) 20 litres of oil cost me 70ish pounds not bad I must say 20200517_041911.thumb.jpg.d8514d6975a5f724d07dbf61a94181b1.jpg

I also removed the rocker cover to check for and sludge in the top end which luckily looked amazingly clean.20200515_154552.thumb.jpg.a3616d88f042294fde8a0c369ef1f7fa.jpg

And while I was at it I thought I’d remove the top part of the inlet manifold to see what state the inlet flaps were. Having read these cars suffer from carbon build up and broken flaps. Which also looked brand new , luckily.20200517_045903.thumb.jpg.b74c3df7bc9cf20569943a7e843d4ea8.jpg

So now the car has been put back together and I have filled her up over 10 litres with a fresh filter new oil, cleaned pickup pipe I am going to start her in the next day or so.

I’m planning to run her for a hour , then Add Forte Advanced formula engine flush in after the hour and let her idle with the flush information 30 mins or so. Then drain off the oil (I know its such a waste but I’m very fussy). Remove the pan once more, clean the pickup pipe and seal it up again. Then put in some fresh oil with a filter, drive for 500 miles and drain and fill again without removal of the sump.

So my main concern after doing this is. SHOULD I USE A ENGINE FLUSH and what would be the best oil to put in after the flush.

I hope I’ve covered everything and will definitely be posting up soon with my experience Any ideas would be appreciated.
