I've had my vibe for about 2 months now and I put synthetic oil in it when I got it (it gets damn cold here) for easier starts. I knew the engine had some leaks when I bought it which I addressed. Rear diff axle seal I replaced and the chain tensioner O ring as well as the valve cover.
When I replaced the tensioner O ring oil spilled down the passenger rear side of the engine and left some residue there near the steering pump and what not.
Last week I noticed a small Oil mark just lateral to the oil pan under the car. Took a quick peak and noticed a small droplet hanging on to the Oil drain plug (i never installed a new crush washer when I changed the oil) I wiped it up and tightened the plug but kept noticing the leak only when the oil is hot after driving and then parking it.
Drive it up on ramps and looked around under the car. The Drive pulley oil seal seems fine as there is no oil under it. However there is oil all over the area due to the tensioner O ring I changed so it makes this challenging to pin point.
Seems to be coming from around the drive pulley area and then going backward and down to the oil pan rear side from the force of the air when driving. I can post pictures later this afternoon. Where I'm at now is I've degreased the engine the best as I could and will be driving the car today and then I'll look underneath again and see where the oil is and post back here.
As of now I believe it is coming from the crank position sensor which would be a failing o ring. Has anyone heard of this being an issue in the Vibe's? Never heard of this before in any car I've owned. Is it possible to buy just the O ring and not a whole sensor from Toyota?
