Side oiler oil passages
I am doing final assembly of my 427 and when I turned it over to install the windage tray I found what looks like an oil passage on the left rear bottom side slightly outside where the oil pan rests.
The passage goes vertically to the oil bypass valve at the rear of th block... Stupid question, but I am assuming my machinist removed it for cleaning and didn't replace it.. It looks like it could be 1/4 SAE thread, (1/8 pipe is too big). Does this passage get a plug? Is it anything special? Also I read in shimming the bypass valve 3/16 of an inch one can gain oil pressure? Any thoughts.. Regards, |
I do not know if their is anything special about the plug but on my S/O it is in place

You can buy a heavy duty spring for the pressure relief valve and forget the shimming. Call George at Gessford. Make sure you install it correctly, spring first, then the piston with the skinny pointy end facing out. Also, don't forget the plug in the top oil gallery that exits behind your cam gear. A screw up I've just recovered from and I'd hate to see anybody else make. Good luck, Steve |
Doc,
Is the plug you have like a bolt with a hex head or is it more like an oil passage plug with an allen head? All the other plugs look like they made it back where they belong.. Thanks for the help everyone.. I will call george.. I bet he has the plug I need too.. |
Like doc, mine was in place also, put it in.
Steve, I did the same as you with the cam gear plug, I pulled the dist. and stuffed a rag down below the plug threads, with two fingers I managed to start the plug and finished it off with a 1/4 drive ratchet. I cut about 3/8 inch off an allen wrench and glued this in socket, which was also cut down. I was able to get this in the dist. hole, and had room enough to work. I didn't want to pull the water pump and timing cover, guess I was just lucky. |
Perry,
You are my hero, that's incredible. You may be talking about the plug that is half way down the dist. shaft, not the one directly behind the cam gear. Steve |
Yes I am!! sorry about the confusion.
|
I checked to make sure that one was there.. thanks guys
|
Steve, when I said 'Yes I am!!', It was in reference to the dist plug. Thanks for correcting me.
|
Perry,
I thought so. I'm glad you were able to get it back in without tearing into it again. Smart to use that rag. Steve |
For you guys with pinion seal leakage on your Jag rears, I found (with help) a little trick that might help....
Mark the end of the pinion shaft and nut with a sharp chisle, in-line with each other. When replacing you have the correct mark so not to under/over tighten the crush washer/shim. Worked for me, after 700mi, no noise/leaks. |
Michael,
This is a access passage for the afermentioned bypass valve. Use a 1/4 pipe plug for this passage!! Hope this helps!! Tom Lucas FE Specialties |
Tom, what's it's purpose?.
