just got new (remanu) engine in my 01 forester, #4 rod knock, covered under xtended warranty!!!!! & in the process it was discovered that the "dog bone" was not replaces/repaired after an earlier accident. i'm looking on the parts list (from insurance) & can't find "dog bone" (wonder why:confused: )

need a part # or more techno name... want to see if it was to be repaired/replaced, & NOT done

thanks

also called a "pitch stopper" I believe

Yep, it is techincally called a "pitching stopper" and is the mount from near the top of the firewall to the top center of the transmission just aft of where it mates to the engine. Might have to remove the big intake box to see it.

 

As for that #4 rod knock. Tell me more. Was it a very noticable mechanical sounding knock at cold start up (I know what piston slap sounds like) that went away after a couple of minutes...followed by a very very muted knock as the engine was warm? Reason I ask, I replaced both head gaskets on my 97 2.5 OBW and since then I've had a knock as I describe that seems to be getting worse. I'm thinking maybe its the timing belt tensioner (hoping that is!) and not a rod knock. But it did seem to occur after a treatment of the Seafoam stuff through the PCV valve when I managed to let the engine die while it was sipping, not guzzling, the stuff. Hate to hijack the thread, but if you can explain your symptoms here or another thread I'd appreciate it!

well, i'm the first to admit that i am mechanically blonde, & 2 guys did NOT hear the noise i heard! finally, i had some one drive it while i was passenger, & snapped my finges every time i heard the noise. FINALLY, he heard it, & pulled over to invesigate further. he did not know for sure what it was, but due to the area where it seemed to be coming from, he suggested i have it looked at. i called dealership, & spoke to shop foreman, & he said it COULD be timing tensioner, BUT could be.....

SYMPTOMS:

under load, between 2800-3200RPM (5 speed) heard faint rattle, especially 2nd gear.

since car was in shop for wreck repair, (almost 3 months) i was very skepticle, since the "mechanic" failed to plug spark plug wires all the way in & it ran poorly & HE couldn't figure out why???? ended up taking it to dealer for diagnosis.....

so, hope that helps, i can only relay what i hear & feel, no mechanical ability or vocabulary! just really glad i listened to my intuition & had it checked before xtended warranty was up!

about the dog bone, don't suppose you know a suby part #??

97 it would be possible to damage an enigne with a Seafoam treatment. there are two ways I can think, but I have not heard of this for years. people used to remove carbon by trickling water down the carb while holding the throttle open.

On rare occasions someone would trickle too much and cause piston slap or full hydraulic lock by stalling the engine solid.
