Heard about this common problem, and peering into the valve cover it looks real dirty in there, so i 'd really like to get it cleaned out, but i don't know a good place that does that. Anyone from around here know a reputable garage in/around Montreal that's does the engine-flush, that you'd recommend?
I'm about to do some engine upgrades and i'm due for an oil change anyway so i'd like to do this first, and soon.

Thanks

FYI -
I found a place that has the 'Renew-Engine power-flush' system that Costco used to have (actually the only place in town now) Gravel Auto in Nun's Island, (514)769-5353. Jean-Emmanuel is the guy to talk to (ex 228. ) I'm scheduling an appointment in 2-3 weeks since i just did the 'treatment in a can' with an oil change, so i'll let that do its job a little before.
In Ontario there's a chain called 'Oil Changers' that also has this machine, there's one in Ottawa which is the second closest to here.
If time permits I'll pop the valve cover and take a picture before & after the treatment, to see how well it really worked. I used to do this with every other oil change on my old pathfinder, and it seemed to work well, everything in there was clean as a whistle.
