Our TL 3.2 has 98k & change on it, and things are good—idle could be a touch smoother, but overall, we've kept it up well. But I'm wondering if I should, just for good measure, change out the PCV valve. It's inexpensive and seems easy enough to do. I welcome input. Gracias!

 

seafoam-gas and Master vac port
clean the TB air plate, spark plugs- NGK Iridium IX, air filter clean?

pull the intake manifold off and clean EGR passages and ports- that messes with idle and clogs up every 75kmiles
With that job, also do the IACV idle air control- inside the bottem of the TB unit
It gets clogged/sticky and causes idle probs-revving probs at idle etc

if the pcv part shakes ok- spray some cleaner thru it and reuse
thats not a big prob on TL , egr clog much more common

 

Did most all of those things. Thanks.

 

you and seafoam again lol


but yes EGR clogging is more of an issue then the pcv on our cars

 

ok just for fries: bg44,seafoam, honda top end cleaner etc are all excellent ways to get the same basic end result = clean parts

Use of something is better than nothing

 

bg 44k is a fuel system additive, not a "top end" cleaner, they have a seperate cleaner for that

 

I was giving a few examples for different makers of quality product
You agree bg makes the right products- and their ad pops up all the time
at the mention of s-foam~
the honda T/E cleaner I saw-- was at their motorcycle shop!
lucas is a fuel additive that list itself as TE as well
Users want more info can use internet~

where do we draw the line on petty bickering fries??
