2010 5.7 - Oil Leak Weirdness (Rear Main?)
Hey guys, I am still new here but already ran into a potential problem with my 2010 5.7 Tundra with 126k miles on it.
Bought it used in January from a reputable dealership.
I drive it about 1-2 times a week for about 100 miles each day so 100-200 miles total per week. No issues after bringing it home and running it to work most of the first week to get the feel of it, no leaks.
A little over 2 weeks ago I noticed a tiny oil spot in the gravel where I park it, no big deal - was not worried about it.
Last week the spot was bigger and I noticed a spot where it sits at work. Spot is bigger. Check the oil and the oil level (dead cold after sitting overnight) is about 1 half inch over the top of the full mark on the dipstick. Still not too worried.
Drive it to work yesterday and notice another spot on the ground where I parked it and I can follow oil drops from where I turned around.
Get home and crawl under - oil drops at the weep hole on the bell housing. Wipe down and watch to see where oil comes from. Very slowly I can see an oil line forming at the seam between the engine and bell housing with the oil drops ending up right beside the weep hole. Oil does not appear to be coming out the weep hole.
Check the dip stick, engine is still warm, dip stick reads 3/4 or so near the full mark and is getting fuller. Assuming it will be closer to full when it all settles down and the engine cools down.
What in the hell is going on lol From reading here it seems the suspects are upper oil pan or rear main seal - neither of which I have the space/ability to fix so it will have to go to a garage/dealer.
Is there some other simple thing it could be? Dealership overfilled it before selling and it is blowing out the surplus? PCV clogged and upped the pressure too much and blew something out?
Just in case you were wondering - it was bought used, so no warranty and I am not dropping a thousand on a truck that I have not even made a payment on yet, so the thing will sit for a while if this is a serious issue. Also only mods I have made was a K&N "cold air" filter kit (I know, I know, they are useless).
