2005 XC90 V8 oil leak

Post by 5ft24 » Sat Sep 21, 2019 6:24 pm

I'm getting really frustrated with this one...
Appeared the rear manifold was getting oily and was smoking after a short drive. Ordered valve cover and intake gaskets, replaced them. Back of the head was dry as a bone.
Cleaned everything with carb cleaner until it was squeeky clean underneath. front, sides etc. Dumped in a little bottle of the fluorescent dye into the crankcase and drove about 1 mile at low speed, pulled into the driveway. shut it off and grabbed the UV flashlight. Smelled oil burning already. Crawl under and the rt front corner of the oil pan was the wettest, but there was enough that it had already made a run to the back and was wet all the way to the oil drain plug. Is the area I circled a broken bolt?

Can also do an internet search on " Volvo 30777727" for images and see what comes up. No bolt there.

What does it look like further up the corner and down past the power steering pump on the front of the block? Maybe remove the passenger side wheel and pull back the flap to get a better idea as to what's going on in the front (if anything). More photos would help with determining the source of the leak.

This is a 2005, you have any history for when aux (serp) belt and all the idlers were replaced? Mileage on the vehicle? Leak any better or any worse since you did VCG?

G is right, you need to inspect through the wheel... there have been some timing cover leaks documented, and if you are getting that much oil out (with UV dye) after a short trip, this would be the area in your pics.

Also, I recently saw a post about the oil cooler leaking on another member's v8 over on sweedspeed. If I come across that post, I'll point you to it over there...

EDIT: Nevermind, it was your post here. I assume you ruled that one out?

I don't have any history on it, but when I did the valve cover gaskets, I looked over the serpentine belt and it looks fairly new. I turned the wheel to the right to make room, pulled back the flap and looked around with the UV and a regular flashlight, thinking front crank seal, and the area around and behind the balancer was clean and dry. It has 114300 miles on it. Bought it 2 months ago

You probably don't want to hear this, but I am wondering if it's the timing cover. The timing cover has the same type of seals as the valve covers, and over time they get hard and brittle too, and stop sealing so well. When I did mine, I did them all. (I had to take off the timing cover anyway, so it only made sense for me.) Otherwise, I know there are some O-rings in the level sensor, which could leak. Also, could it be a bad o-ring on the oil filter? (Looking for the easy things here...) :)

Definitely not oil filter. Replaced the housing and filter, made sure there wasn't an old o-ring or pieces up in the threads. Hope it's not timing cover, valve covers were enough of a bitch

The other thing to think about is, you said the belt looked new. If this one suffered a failed pulley bearing, it may have cracked the timing cover. so look closely around the tensioner and pulleys.
