2015 Forester pinging


Asked by Oct 28, 2015 at 01:26 AM about the 2015 Subaru Forester 2.5i Premium

Question type: Maintenance & Repair

Going up hills the car pings badly ever since I had a new short block installed.  
I am trying 89 octane gas but it still seems to be pinging and I think the dealer
mechanic created a problem when re-assembling the engine. The car is not a

Does anyone else have pinging problems with their new Subaru?

The car just does not run quite right and the engine sounds noisier than it should to me. The gas mileage is off maybe a 1/2 mpg as well. I don't know if they got the ignition timing wrong or the cam timing off or something else but the engine is not quite right anymore.


check to see if your mechanic has not put something back on right or forget to do something up

It is still under factory warranty, take it back to the dealership.


Without disassembling the engine I can't tell if the mechanic did something wrong or not. The dealer seems to be causing most of the problems so I have to drive 4 hours to get to another dealer.


dude you are getting a total shaft on that fozz.. :( I'm like.. in a daze at how many issues you have encountered. If you run 93 / seafoam it might help?

@walth, hey, he has a new engine so it is free of deposits. Seafoam won't do diddly squat except deflate his wallet. Pinging is probably caused by a timing issue, excessive compression, sensor problem, fuel quality or pressure issue or something with the ECU. Subaru needs to step up and fix the damned thing. Something has been missed here.


Well folks I found out that the engine is full of RTV gasket sealant bits due to excessive sealant applied during assembly of the engine. I cut open the filter and it is full of grey RTV bits! A very insightful service manager at another dealership suggested that this might be the case based on my description of the problems I was having and he was 100% right! Now I have to deal with the dealer who screwed it all up.

I did find out that there is a software patch for cars operated at high altitudes which might solve the pinging problem.

It wasn't my idea on the seafoam, it was in that thread. They said it would negate the pinging for about 1000 miles but it was an expensive alternative to 93 octane. It comes out close on price but whatever.

walth, my apologies....I just skimmed your post and missed the question marks. Glad "Full_of_Regrets" is making some progress on this problem.
