Wynn's Wins or does it?

hmm... my last post, below, wasn't s helpful as it could've been. sorry.

If you're chasing a 'tick' int he motor, I'd want to first understand what's causing it, then approach a repair on it.

I haven't seen any other posts detailing this tick, so the questions I'd ask are as follows:

1. Does it go away when it's warm?
2. Is there ANY change in the sound (duration, frequency, pitch, etc) right after an oil change?
3. How many miles on your motor?
4. How long has it been making this noise and is it getting worse?

1 second rattle on start up is very common on older boxsters, Its simply until the oil pressure builds up to the lifters.... common on a lot of cars infact. Id be willing to be my mortgage that the additives was not the cause of your friends problem.

I'd take that bet all day long, friend. And as I said before: that was only one of MANY instances where oil additives have caused serious harm.
Don't be fooled by the guy at oreilleys who has never seen the inside of a motor. These additives are ALL designed to mask symptoms, not solve anything.

Seems you are quite certain it's the hydraulic lifters. How do you know this with such certainty? What diagnosing method did you use?

If it is, in fact, your lifters, then let's reason together: why would it tick for 1 second, then pump up and stop? These lifters in this motor lay horizontally, so we could presume the oil is draining out of one or several when it sits. (This is a leap! But we're chasing your theory here). If you're going to ask an additive to make the oil STOP draining out of the lifters..... let's think about the ways it could do that. Hmm.... do any of those ways seem like they'd be good for the rest of the motor?

Exactly.

When the engine is shut down, one or several lifters are in various states of lift and are under compression by the valve springs. With no oil pressure, the oil in the lifter is forced out. Contamination in the lifter can stick the lifter in the compressed state. The resulting clearance can damage the lifter from hammering.

Yup.... all true.
So how do you think an additive will solve this? I know how I, and thousands of other Racers have solved this over the years, but I would love to know how someone thinks and oil additive will solve this.

According to the good doctor Raby it may actually make things worse. The lifters are at the end of the lubrication stream. An additive may cause any contaminants cleaned from the engine to be deposited in the lifters which are not flow through, potentially causing them to fail. This is another good reason to keep up on oil changes.

Exactly.
This is only ONE of the results that can cause major damage internally.
I just wanted the O.P. to think through it with us, so he'd have buy-in, since his posts suggest that he is sold on these additives.

Wow theres a lot of "mays" going on in this thread
