Power steering pump leak

Hi All,

Tried searching but didn't find much. I think my 08 V8 4Runner (105K miles) has a power steering pump leak. It doesn't seem like a common issue with these vehicles, so I'm wondering if anyone else had this happen to them? Two pics attached. I assume the pump is leaking. The alternator beneath it is getting oil on it. The valve cover above the pump is also slightly wet, but I think that's from the pulley slinging it around. Seem like the pump? Reservoir only has a slight reduction in oil. No hard steering, but i believe it does make noise on startup on extra cold mornings.

Thanks,
Brandon

Check the lines. My v6 had a similar issue and I found a weep on the return and it was just was a matter of adding an extra clamp to the hose. Real pain to access it though.

Thanks for the reply, but all the hose connections were dry. I took it to the local Toyota dealer today and there were unable to determine the source of the leak and could not duplicate it. They just cleaned it up and said to keep an eye on it. So I'm back to square one

So why not just replace the pump? Seems obvious from your description.

Truthfully, I'm not fully convinced it's the ps pump leaking. I'ts not making any noises, not loosing any fluid through the reservoir, and no difficulty in steering. I also asked the service rep if the tech thought the pump was leaking and they weren't convinced it was either. So I'll have to keep looking to see where it starts now.

It looks like it's leaking from the valve cover or possibly the cam bearing cap. I would imagine if oil was slinging around from the p/s pump pulley, you'd have a larger mess in the engine bay.

There's also an o-ring on the return line fitting where the rubber hose connects to on the ps pump. That might be the likeliest cause for the leak since it's pretty wet there.

Thanks for the suggestions Weaves. I'll have to give that o-ring area a close inspection.

I just had a super painful experience with this. A piece of serpentine belt ruined my power steering pump. I was quoted 600 to replace it. Then I got a call saying a bolt was seized on the return line. That bolt is not an individual bolt but part of the return line itself. Another 600 on top to replace that too.

Ouch! that price is a hard pill to swallow.

So, it has started to leak again, but this time the source is a little easier to locate. It's above the power steering pump. So I am going to assume it's either the valve cover gasket, intake cam seal, or exhaust cap seal?

I'm going to make another appt at the dealer to confirm. They told me to bring it back if it starts to leak.

To be continued.....

Update: Turned out to be the valve cover gasket. Dealer replaced both and broke six bolts in the process. Also claimed timing cover gasket was leaking. In typical dealer fashion, the total was just shy of $1,300.00.....

$1,300 for valve cover gaskets?

I'm not too surprised they broke several bolts since you're from the Northeast. They're just tiny M6 bolts which run all the way through the cylinder heads so the bottom of the bolts get exposed to road salt and water. I broke a couple when I did mine and I have a rust-free Southern vehicle.

And what's this timing cover gasket that you speak of? Only the 4.0L V6 has a timing (chain) cover that can leak oil. The V8 uses plastic timing belt guards to keep debris from entering the timing belt area.

Hi Weaves,

Yep, all the bolts that broke off had the exposed bottoms to them. I'm attaching a pic of what was repaired by the dealer.

Also, when I got it back, it developed a noise that sounds like a common-rail diesel. So I had to take it back and they tore down the right hand side valve cover, removed the cam and set the pretension on the cam. This of course they had to do for free since it was there mistake. So far so good.....

What they're calling the "timing gear cover" is actually a cam bearing cap. Now it makes sense why your repair bill was so high to reseal it because it involves removing the timing belt and camshafts. However, it sounds like you may have had some unnecessary repairs done due to an incompetent tech working on your vehicle since they did not properly install the set screw in the exhaust cam gear while removing and installing the cams. I would also question if the cam bearing cap was leaking at all to begin with. It's sealed with FIPG (RTV) from the factory so it's unlikely that it would leak without being disturbed.

It did just start out as valve cover gasket replacement, but the service manager called and said the cam cap seal was leaking, and would end up costing around 1200 to fix - and if I wanted to proceed. Since I plan on having the 4runner for about five more years I told them just to replace it. It is the first major repair I've had to do to it since owning it. Whether or not it was actually leaking I'll never know.

I will say they admitted fault in reassembly. They gave me a loner and fixed it the next day free of charge, as I would expect.

My only concern is that I drove it for about a week with the cam lash out of spec. I wonder if there is any long-term damage that may occur as a result of this?
