My 2000 f-350 7.3 with only 78,000 miles on it looks like it has a rear main seal and front cover leak. can I use ( Bar's Leaks Rear Main Seal Repair (p/n 1050)) to see if it helps or will it hurt the injectors?? I have the oil drained out now. I called Bar's and asked them and they said they would into it and call me back. Just wanted to know what you think.

Bar's called me back and said I can use it in my truck and would need to put 3 bottles in. I just do not know if I like the idea of putting it in. any ideas of what I should do to stop the leaks with out pulling the trans?

 

DO NOT do that. Oil additives mess up and can severely damage the HEUI system.

Second....shouldn't have drained the oil... chances are very good you have an oil leak somewhere in the valley, either the HPOP, HPOP Lines, Turbo/Pedestal, etc. You need to clean off the engine to locate the leak.

 

Thank you!! I know there was a reason I did not want to put it in. I put new oil in and will wash everything down and hope to see where it is coming from. like I said the truck is a Feb 2000 but only 78000 miles on her.

 

Clean up the front and back of the pan well, my 99 leaked where the pan seals to the front and rear housings....
I 2nd tomango, could be from the valley. Possibly turbo pedistal o-rings leaking or the ebpv piston...hpop...intake plenums...
Def. DONT use the bars!

 

check the oil plugs in the back of the head they will look like main seal leak

 

Main oil leaks are EXTREAMLY RARE for these trucks.

Its more then likely something else.
