I have an oil leak on my 6v92 that appears to be behind and slightly above my water pump (as you look through the engine door). The leak is just left of the tach drive cover. To get to this I'm going to have to get the water pump off to see behind it to pinpoint the source. Any hints on easy removal and reinstallation?
It looks like a full day's job, ie, draining the coolant and removing those big hoses, etc, etc.
Thanks,

If you will look at the rear of your water pump you will see a weep hole. The oil is comimg from the seal on the water pump shaft. You will need to replace the water pump to stop it. You may have to use a mirrow to see it. |

David I had the same problem and I added a gallon of Lucas oil or engine conditioner and it stoped the problem. For $22.00 give it a try. To remove the water pump thers is a bolt on the back side of the pump. You can use a mirrow to see the bolt head and you can also feel it.

I've heard some magic about Lucas oil, but also negative stuff, also. I may give it a try.
I've tried to get a mirror and light on it but still can't tell exactly where it originates. The pump shaft seal sounds logical. Is removal and installation something I could do or should I take it to a pro?
Does the pump shaft extend from the block? If so how do you remove the pump body from the block? Unscrew the impeller?
Thanks,

David I think there is only 4 bolts holding the water pump om. It is gear driven. It is not a big job to change it. I changed mine. You should be able to get a rebult pump for under 100$. Make sure you get the same pump that you have. There is two different pumps one is called a walking pump. The other is called a standing pump. It has to do with the bottom hose connections. The Lucas oil addetive is some good stuff. I use it in every thing I have. I have it in the diff, and the transmission too. |

A good way to search fo leak sources is to fasten a blue shop towel or a kotex to the suspected site so the oil will have to show up on the spot that covered the leak. You can first clean all the oil off with brake cleaner or stater fluid. If you use starter fluid, shut down all eletrical stuff in the area, do it on a cold engine and air the area well for an hour or more before starting. And don't breath the fumes. They are mostly ether and it takes your body about 2 days to clear out what you breath in. Meanwhile you are impaired. Starter fluid is probably less of a health problem than brake cleaner, though. |

I got the water pump off. Only 3 bolts hold it on, but all the hoses and pipes and draining the coolant turned it into a 3 hour job.
The oil ring was cracked and very brittle. A new ring was $5.00 and 90 minutes to reinstall and hooray, no more leak. There was no sign of any leakage out the weep hole. The oil was running down the crankcase wall behind the pump. I ran the engine up on high idle and covered the radiator with a blanket to get the beast to 170. I need to take her out on the road to get all the system burped out and recheck everything.
I'm glad this problem is behind me.
Thanks, for the help.
