It seems like this has been discussed before but is there a document specific to the 65 400 engine...local automotive literature seller (Faxon) says that the 66 service manual covers the 400...reason I ask is that my 65 seems to be flinging oil from the front seal and I wanted to see what the procedure is to change it...would like to have the document anyway for future fixes...
Thanks

Thanks Other than the bore, the 400 is identical to the 425 and service procedures in the 1965 CSM for the BBO apply. |

Like Joe said, all the 425 info relates.
If it is just the crank seal, you can change it in the car and it’s not too bad. You have to remove the radiator, fan and remove the belts. Then remove (with a proper removal and installation tool) the harmonic balancer. You can then remove the old seal with a pick or small roll bar. To install the new seal you should use a tool to go over the crank. If you don’t have one you can make one out of a piece of PVC pipe.
One thing to check carefully is if the seal area on the crank is marred or cut by the bad seal. Seal companies make a kit to repair the groove with a sleeve to go on the crank. I doubt that their reference material will go back to 65, but you can look one up by the crank diameter. Now, I’ve also seen the oil pan to the timing cover seal go bad and also sling oil. For that to repair in the car you’d have to jack up the engine and drop the pan to replace the tiiming cover gaskets and seals. Maybe some other members will have a short cut to replace the timing cover gaskets and seal, but I’ve never had one go in and NOT have a leak somewhere else. If I’m not mistaken, I believe there is a 65 TSB with procedures for replacing the oil pan gasket in the car. I’m not home and can’t look, but maybe someone else can.

Hey Joe and mike,
thanks for the responses...i will look further at the Chassis Service manual...for some reason I had the idea that there was a separate document for the 65 400...
Anyway thanks for the information and I will dig further into the leak to determine for sure if the source is is one or the other... slinging oil onto the alt. bracket, inner fenders and center link and ground...nice mess to clean up now...

One thing to check carefully is if the seal area on the crank is marred or cut by the bad seal. Seal companies make a kit to repair the groove with a sleeve to go on the crank. Just to clarify, the seal does not ride on the crank, it rides on the balancer. FelPro sells a repair sleeve for this. If you can snag your fignernail in the groove, put the sleeve on. FelPro actually sells the seal and sleeve as a kit. |

Damn, thanks Joe for keeping me straight. I swear my brain has been mush lately!
