Frank,

 

I did the first cycle, adding 14 quarts of oil in 3000 miles.  Blackstone oil analysis said that the sample I collected when I changed the oil looked very close to unused oil, that couldn’t detect any additives in it, and the additives probably disappeared with the 14 quarts of oil.   

 

I have a 2002 Toyota Avalon with the 1MZ-FE VVTi V6 & it apparently has so many sludge problems that there are lots of posts on how to solve it.  I discover sludge when I replaced the front valve cover gasket, but the motor is canted back so much that the rear valve cover is virtually impossible to get off, so I skipped it.  Mistake, big.  It’s gone thru nine iterations/part numbers & the most recent is 11201-0A060.  I found a couple of postings about it.  This one on ClubLexus.com has pictures of the latest & greatest & it’s predecessor showing how it’s been improved & a story about a road trip from Atlanta to Salt Lake City with the predecessor & a new PVC valve that went thru 18 quarts of oil  & the return trip with the latest & greatest that used nary a drop.  Of course the old cover was probably clogged & the new one wasn’t, but still, that’s impressive.

 

So I’ve just replaced the rear valve cover with the latest.  The baffles in the old one were so sludged up that they blocked internal engine airflow to the PCV valve, so my new valve was doing nothing.  

 

On the plus side, my compression has improved dramatically.

·        1 – 2nd time 190 psi 1st time 205 psi 

·        2 – 2nd time 195 psi 1st time 152 psi dry 185 wet 

·        3 – 2nd time 190 psi 1st time impossible to get to…

·        4 – 2nd time 185 psi 1st time 170 psi dry 195 wet 

·        5 – 2nd time 180 psi 1st time 190 psi

·        6 – 2nd time 185 psi 1st time 188 psi

Big change!  While none were near Toyota’s 218, they all were within 15 of each other & well above Toyota’s 145 minimum.  All the plugs looked fine except for #2, the coal mine canary, which was badly oil fouled.  As it’s on the front bank, I’m seriously considering replacing just it’s seals.
