Power Steering Pump Leak Common?
I was changing the oil on our 2010 this weekend and I noticed a lot of build up on the front, passenger side of the block as well as below on the front skid plate and rear one below the engine. I thought it was an oil leak at first but the dipstick did not show any loss of oil and there is fluid slung on the lower area of the passenger cylinder head. My guess is a shaft seal leak on the PS pump. Has anyone had this happen on their 5th gen?
I've found some low mile used pumps but it looks buried in the accessory setup. I can change the pump in 20 minutes on my 4.7L Dakota but this looks like a frustrating job. The PS reservoir was only down about 1/8" and was barely below the "hot min" line and was recently driven. I don't know if the expense and time (read frustration) is worth it for such a minor leak. I don't see any drips to completely diagnose this issue either. Thoughts? |
I do not recall seeing Power Steering Pump Leak reports on 5th gen 4runers… so if you truly have it you may be the first one…
First thing I would do is clean all the “buildup” and figure out if it is power steering leak… Not to bring the bad news… but it may be oil leaking from timing cover -I am not going to call it common, but I have seeing reports of that issue especially on the early 5th gens (mainly 2010-2012) - here is the link to one of the discussions: Timing cover leak = first trip to dealer How many miles are on your truck? From what I know, timing cover leak would appear with fairly low mileage (under 30-40K)… Keep us posted. |

We have 90k miles on it and I've been religiously changing the oil every 8500 miles, heck first one was at 1250. |

You have mentioned a “build up” and now you added “no oil spots on the driveway”: sounds like a slow leak and that is why timing cover leak came to my mind… if it is timing cover, I would recommend contacting dealer, as they aware of this problem and may know about TSB for it… if you are lucky and you have a good dealer they may assist you with repair (partially paying for it) even with 90K and 9/10 years old truck… I know it is a long shot, but maybe worth trying if you planning to keep the truck for a long time. If not, as you said, you can probably drive it as it is. Good luck! |

I will double check the driveway when I get home but I think I would have noticed. Most likely the skid plates catch all of the drips/runs. Ironically, the jacking point near the center rear of the oil filter skid plate has rusted out. Go figure. Thanks for the reply. |
No issue with PS leaks on ours

Also have a whine that really sounds like a power steering pump to me but no noticing any missing fluid. |
Your ten year old vehicle has a leak? Say it ain't so!

The oil leak has yet to leave a stain in the driveway but there is a layer of it all over the passenger side of the block and skid plate. The lower portion of the head is more of a dusty oil cake. It does not seem to effect the level and it comes back when I clean it, which is really only annually when I change the oil. It's not the PS pump as initially thought. |

Just completed it two nights ago and so far it's clean under there. Did it fix it? Don't know yet.... but it may be worth looking into in your case. Unfortunately, it's a biotch to see up in that area from above, below, or from the wheel well. Here's the parts list for the job anyway. Good luck to you! 15772-31010 Pipe, Oil 90401-16043 Bolt, Union X2 90430-16016 Gasket, lower end of the line 90430-16012 Gasket, to Valve cover X2 Bolts may not be needed, but I replaced them anyway. Banjo bolts are 48 Ft Lbs Power steering pump bolts are 32 Ft Lbs You need to disconnect the PS pump and let it hang to access the lower bolt and remove the air filter to get easier access to the top bolt. Whole job took me 2.5 hrs from beginning to end. Here's a few pics. Does yours look like this?https://uploads.tapatalk-cdn.com/202...566c8d9a05.jpghttps://uploads.tapatalk-cdn.com/202...bd8c2a80e1.jpghttps://uploads.tapatalk-cdn.com/202...71c3d90108.jpghttps://uploads.tapatalk-cdn.com/202...b245621d4a.jpghttps://uploads.tapatalk-cdn.com/202...bb2dff66fc.jpghttps://uploads.tapatalk-cdn.com/202...7ea5d334ce.jpghttps://uploads.tapatalk-cdn.com/202...673c5e765d.jpg |
I created an account just to thank you! I too found oil leaking around the PS pump but not from the valve cover. After reading your post and taking a closer look, I noticed crusty oil all over the bottom end of that oil line exactly as described!
|
I am super curious on this one… Did your oil leak get fixed by replacing the parts you mentioned?
Thanks. John Quote:

Also talked with @EddieV4runnin and his seems to have done the truck as well. I believe he has several thousand miles since swapping the line. If you suspect it I suggest you give it a shot before going deeper. It is a very basic job relative to the timing chain cover, and if it works, it works! If not, then go down that road..... |

https://i.imgur.com/xBMysq6.jpg Traced it's way to the thicker gunk of the lower lower part of the VVT-i line as you described. The oil splatter is heaviest around that area looks like it's the source. Sprayed it off with Simple Green then soap and water. I'll be monitoring it to make sure it's coming from there. What's the consensus if I don't fix this right away? Would oil pour out from the bottom connection at all? Or do I need to do this during an oil change? Thanks for those parts list and your tips for this job too. I have just over 51,000 miles |

Me personally, I couldn't sleep good at night knowing that I have a leak, so I took care of it. Wasn't too terrible of a job, but I did scratched up my hands pretty good getting back in the cramped space. So, moderately difficult, but pretty quick job. Since yours is so minimal right now I personally would give it another five to ten thousand miles and see if it even gets worse. Maybe that's all the more you're ever going to see of it. Good luck! |
