Default Front of my engine looks rather oily

I noticed there was some oil on the bottom of the engine a few moments ago and then decided to see what is up. And this is what I saw. I am a couple of miles from home. What would be the possible sources for all of this oil? Cam seal? FYI, I have cleaned my PCV system months ago.

My bet would be on the cam seal. Can you bend the plastic timing belt cover backing forward a bit to see the cam and seal?

Thinking camshaft seal prolly? The last time I did water pump, timing belt, etc..I noticed the orange(Elring?) cam seal looked perfect, then ironically it failed less than a year later on a low miles DD brick

IPD had genuine Volvo Camshaft seals on sale, and I ordered one from them.

So I decided to peel behind plastic thingie. I do not know about you, but it looks dry to me:


But, over here looks (aux shaft?) rather wet. I am not saying that is where it is leaking but I am wondering other places it might be leaking from.

I would replace all the seals, might be a PITA but what one is leaking?

I'm thinking it could even be the crank seal, allowing oil to pool up in the bottom of the lower timing cover, and getting flung everywhere by the timing belt. Do you always keep the upper timing cover off?

I try not to but broke the cover last year. Need to get a replacement one...

Are the front seals (crank/aux shaft) dimensions for a B230 the same as in a B23? I have a B23 block at home and was going to measure the holes so I can make me some seal tools.

Incidentally, does anyone know what is this (blue arrow) supposed to be? Just saw that and am away from car, so...

Looks like the location where the 12mm headed bolt goes for the upper cover.

From what I gather, yes, the seals are the same, as I figured from this iPd listing: https://www.ipdusa.com/products/1060...xoCjN8QAvD_BwE.

Also, that hole should be for the lower upper timing cover bolt, as dl242gt stated.

I'd change all the front seals, the timing belt, and get an upper timing cover. I don't see a reason to do all the work to replace only one seal. In addition, I don't know how that amount of oil would affect the timing belt, although I can't imagine it would last much longer without getting all gummy and failing.

If there's a groove worn in the auxiliary shaft you can buy repair sleeves that just tap on.

Nice I just use the right sized socket myself to tap it in or an old seal and a piece of wood.

A PVC coupler and a rubber mallet works too. Can't blame you, I'd have done this too if I had a 3D printer...

The actual seal installer tool from Volvo was only about $45 a couple years ago when I bought one.

What's so different about the actual tool when compared to a deep socket?

The new tool has a thin section that you place the seal on prior to installation. It protect the lip of the seal from scratches or rust on the snout of the cam.



The old tool (on the left) just pushed the seal in.
