New to me 05 Sportwagon is oily

Are there common points of failure with the gaskets, seals, boots etc? I haven't been able to spend a whole lot of time under the front to track down the leaks I just know that its messy underneath.

Off the top of my head. Timing chain cover, oil pan and valve covers.

^^ What he said. Check your PCV valve/hose as well since those are prone to cracking/breaking and are a super easy fix.

I just picked up an 04 wagon and the valve covers were leaking badly. Particularly the front one. It was about a 4 hour job to pull, clean(this took the most time), reseal and replace them.

Mine has been all timing cover until recently with the bank 1 valve cover. Rust protection.

Timing cover....
Seems likely.


Also brings me to another question:


When pressing the throttle from idle, such as when starting out or even in neutral or park, I can hear a tapping, clicking, or mettalic throbbing that increases with the rpms but appears to quiet by 2K. IOW, I can only hear it from idle speed to 2K rpms, whether driving or stopped. I wonder if it is a loose timing chain, that rattles until up to speed.

I've been playing whack a mole oil leak with my wagon for the last two weeks. I had a leaky front crank. It was the seal and the end of the crank needs to be sealed with silicone behind the crank bolt. Another source of leaking was my oil pressure sensor.

Isn't this the front main seal? I don't think silicone alone will do it. Is that exactly what you said?

That one should be easy. Remember it is into aluminum so don't over tighten it.
Well done.
Show us some pics of the ride when you get a chance.
