I also wanted to ask if that oil control solenoid screen is easy to get to for inspection or do you have to start tearing down the front of the engine to get to it?
Did I miss someone elses comments on the solenoid oil screen?
First to answer your question, the solenoid is right under the intake mainifold in the front part of the lifter valley. Pull the manifold and I "THINK" it will be right there. I saw it when my engine was being reassembled.
Now what I want to know is does oil pressure have anything to do with keeping the chain tight??? The mechanic that worked on my told me the day it broke that he figured that it had lost oil pressure, and that was without even turning a wrench! After he had the engine completely apart he said that the screen had broken off the solenoid, he even showed it to me, and said that the screen went into the pressure port that I thought he said held the chain tight??? HOWEVER people on here, and another place I asked say "NO", "Oil pressure has nothing to do with keeping the chain tight!". WHO REALLY KNOWS???? A guy on ask.com or whatever sent me a parts breakdown of the chain tensioner and said there was nothing on there for oil pressure, but when I read the parts breakdown for it, one piece that the spring rode in was called the "Plunger"? I've never had one of these things apart myself, so I can't say for sure, but "plunger" in my limited technical vocabulary was always ment to mean something that was forced by something? Could this be the part the oil pushes on? I REALLY THINK that if oil does have something to do with chain tension, this could be a significate factor in failures! I'm not ruling out harmonics or resonace either, I've flown lots of planes in my career that are placarded to now run the engine at a certain RPM for an longer than a specified amount of time!
Without going back to look at he first page again, and I apologize for that, I THINK my car had the lowest miles on it when this failure occured? I CAN TELL YOU FOR A FACT, my car has spent AT LEAST 80% of it's life between 70 and 80 MPH, and that's when it seems most, or should I say a MAJORITY of failures occur.
Another thing I have noticed about my car since I've gotten it back is that it now spends MUCH MORE TIME IN MDS! I haven't had a chance to talk to the tech yet to see if it was reprogrammed during the repair or not yet, but I can tell you for sure now that the only time it isn't in MDS, is if I'm actually accelerating at a reasonable rate, or if it's just idling at start, or at a light.
I wise we could get more people on this link discussing REAL FAILURES and REAL EXPERIENCES, that we have just tossing back and forth opinions, because we all know about them!
