Got a rattle
Well as I seem to make a step forward I get knocked back 2. I have noticed a couple times lately that when I have the car under a heavy load (yesterday passing on the highway) I'll get an occasional rattle at higher rpms.
I have only had it happen on a few different occasions in the last couple weeks, only while under a decent load and of course when I'm not datalogging.
First thing I did each time was look at oil pressure gauge and it was reading right around 75psi (it's a working gauge not the factory one). Gauge seems to read fine in all of the normal ranges, (once engine is warm 25psi at idle, approx 50 psi cruising, etc...) and I just changed the oil less than a week ago w/Motorcraft filter and Mobil 1 5w-20. Don't feel any loss in power, no blue smoke, or pinging.
When I had the timing cover off about a year ago the chains and guides looked good with no overly pronounced wear but I did install new tensioners just to waste money (not really just was misinformed before I purchased the parts and since I had the engine apart...).
I have been having trouble with my trans or trans tune which I think is related to the TC and not the Trans itself. Wasn't sure if a TC would rattle if it was starting to fail and it doesn't misbehave at light to med loads. Also the rattling didn't sound like it was coming from the trans tunnel but from under the hood so that is why I wasn't really expecting that to be the culprit on this problem.
Just wondering what I may be seeing as starting symptoms to a larger possibly costly problem.
