Outback countermeasure piston kit installation
Posted 25 May 2004 - 02:50 PM
Just had a Subaru regional rep okay their installation to get rid of piston slap in my 2000 Outback. He also said that if the cylinder walls don't meet spec, that they would install a new short block. My major concern is obviously whether the dealer can do the work properly, though the dealership is highly regarded here in the Massachusetts and the work is warranteed by Subaru.

This was on the old ezboard, so you probably won't find any posts about it.
I don't know that anyone ever quite figured out what countermeasure pistons were (CCR Inc could probably tell us). My best guess is that they just put in pistons with tighter / matched tolerances to the cylinders. *shrug* Just a guess.

They probably tried to lighten the whole mass up by using those short-skirted ones, not that I have anything against short skirts, just not in an engine or on Rosie O'Donnell

I would also be looking for a good length on the skirt as the tiny increase in power and fuel mileage is not worth the Peterbuilt imitation on startup to me.
At this point with 100,000 plus mies on my Forester the engine is holding out well but the transmission is getting more musical as the mileage goes up. I suspect I may be changing the tranny in the future but the engine may hold out till I am done with the car.

The entire process started quite a bit ago. It took a while to get the zone rep in to look at the vehicle (over a month) and then a couple of weeks for the dealer to get the parts in, but now it is done and all under warranty.

Glad the work turned out alright.
Did you happen ask anyone what's up regarding #2 & #4 slapping, but not #1 & #3?

I had my #2 and 4 pistons replaced under warranty last Jan 04. The only way I know to have them install countermeasure pistons is if the noise is always there . . In my case my piston slap noise never went away even when car was fully warmed up . They say it could take up to 10-15 mins untill noise goes way . I had them done a 43k miles i now have 53 k miles and this winter i got my start up noise back . Not as bad as before and it only takes 1-3 mins for noise to go away . . I do have a 7year 100k miles warranty so I am not worried.
