ATP-205 works!

Post by **jtp** » 12 Feb 2018, 19:26

Just added some to my 99 v70R with 142K. Hoping to buy some time on my vvt/exhaust cam seal.

If it works even for a while I’ll probably make it regular for the sake of my not-yet leaking exhaust valve stem seals. Exhaust valve failure due to seal leakage seems to be biggest danger to the internals of my engine type as I gradually approach 200K.

What's in this stuff, anyone know?

It has odour and consistency of organic ethers

Before I threw the bottle out I think it said glycol ether

My front cam seals were very hard & crusty when replaced a few years back. They were leaking. I'd never replaced them. Not sure if shop did them either on TB change.

Your second post got me to thinking. I've never used 205 in the engine oil. Sled motor doesn't burn any oil at ~ 226kmi. Might be good preventative maintainence however.

I am using M1 HM oil which I believe contains 'seal conditioners' however.

+1 on M1 HM, I changed it out for M1 0w-30 last oil change, everything started leaking.

Going back to it this week, been running ATP-205 for maybe 100 miles so far. I haven’t had a chance to look at it’s impact yet.

Hmmm. Brake fluid.

BTDT with 0w-30. Oil consumption really increased. I regularly ran Shell T6 20w-50 for years. Worked great. Then when gas went through the roof, I took it down a notch to increase MPG. After doing lots of homework over on BITOG, I decided on the present fill as it ticks all of the right boxes for a turbo motor + high Tx. heat.

I left my ATP near my cell and it turned into ADP plus energy. Some guy named Krebs came and fixed it back though.

Ouch.
