No I have not done any engine work to the V6 engines except replacing oil
Did you notice any sludge building up in the engine?
There are some products, if you choose to use them, that might quiet down
that lifter. CD2 makes one that I have used with some success on some VW
engines. http://www.autobarn.net/ch4111-12.html but sold at local stores
You can do a search on google.com and see about this product.
This is what I would prescribe:
Instead of pulling things apart............first try an oil change using a
good filter like a MANN oil filter and the CD2 oil detergent.
Yes you can use some good organic oil like Valvoline or Castrol 5W-30 oil
for this first application.
After this fresh oil try idling the engine at different RPMs to lessen that
noise of the ticking. Hopefully you will find that the noise lessens right
around 1200-1600 rpms. Hold it there and sometimes rev it a little higher
returning it to about 1200-1600 or the sweet spot. Kind of like lightly
gunning the engine
It might just start to sound better and better..............fingers crossed.
THEN when it quiets down, just drive normally and change the oil at about
3,000 miles or sooner with the organic oil.
I vote if you want to extend the oil change interval use synthetic oil such
as Mobil 1 or one of the VW approved brands like Elf or Pentosin. Don't ask
me how long I extend the oil change intervals too with my personal rides.
This will sure beat the $$$$s you would spend otherwise if it works.
Fingers crossed for you and let us know if it works out!
