Darn leaky engine - BusNit - 10-12-2022

I thought my oil leak was limited to an oil pan gasket but as I was looking at battery wiring up and over the alternator area, I noticed a sizable leak at the rear of the engine going down the bell housing. I did cinch down the two bolts for the power steering pump but they didn't appear to be that "loose" to cause a leak of that size. For those of you with a 8v92 anything you could shed some light on for me? That area of the engine seems to have a thick caked on layer of greasy dirt. Maybe my almost 6k of high speed mileage exacerbated an already existing issue? I am a believer that all engines can be leak minimized. Overall the topside of this engine is very clean and dry.

I had a leak in that area with my 93 coach that involved the tach drive just above, a bit forward of the power steering pump, and in the valley on the inside of the rocker cover.. it was a contortionist’s dream to see it.

Thanks Jon! Yeah, I was a bit disappointed when I removed the bed thinking I could unscrew the base and get access to the engine. Not the case. Area is built sealed off.

Been there done that. No interior access to the engine on the 8V92's of the early nineties.

In your quest to locate leaks, don't forget that you are dealing gaskets that have been in service for nearly 30 years.

Yep, and I will chase them down! I did find an oil cooler leak that was the result of two loose bolts. I believe these leaks have always been there due to the caked on buildup of greasy dirt.

Forty weight clay .  
As stated before , gaskets and seals .

Someone (not me ) cut out a section of the bed base for engine access on our '86 . They did a pretty good job of it,  fits snugly and held down with screws . Not sure I would have cut it out , but it gives good access to the top of the engine . Alternator , compressor , covers over unused drives , etc are all possibilities for leaks . Pdf service and parts  manuals are available online . If you don't already have manuals I recommend getting them to get a better picture of the engine's layout.
