Little Hole

Ok, so riddle me this, lookin at a 350 up front, on the left side, above the timing chain cover and below the manifold, there is a valley and a little hole off to the right. 1. what the hell is it? 2. could oil be coming from it. 3. is there a way to fix it. 4. any other ideas where oil could be coming from because theres always a small puddle in that valley. its not the chain cover, manifold, valve covers, or the heads. where could it be?
Thanks,
Cole

Re: Little Hole

This is a 283- but are you talking about here? If so- yes it needs to have a plug 1/4 " NPT I believe.

They are plugged from the outside- so if there is a hole there, and it is not leaking anyplace else- it is probably from there- I would think. I would just plug it with a new plug.

Re: Little Hole

I think you could use that for an oil pressure gauge. Most are using a hole near the back of the block. But yea, I would just put a new plug in it.

You can but the plumbing looks awkward. The one at the back or rhe one by the oil filter usually works better. Jay

Re: Little Hole

If you do pull the plug out clean the threads on the plug and in the hole real good so they are free of oil, then apply some permatex thread sealant on the threads and screw it in.

Do not use teflon tape. It's ok for low pressure water, but oil, gas, or antifreeze will blow right past it.
