a little schooling please,these two lower intake bolts were leaking oil into the valleys in the pic,is this normal?,or do i have an issue?....i took the bolts out and they had oil on the treads,im thinking they go down to the head and the oil is seeping up?,i put sealer on the top of the bolt seems to be fine now...?

Is that your engine above? Do you still have your EGR functioning?

If so, it looks like you forgot to cut the centre out of the gaskets for the EGR port and it's probably starting to build up oil and sludge in the area and is starting to seep?

In any case, I'd pull the upper off and retorque the lower to about 15-18lbs ft.

yes thats mine,and i have no egr....there is no oil around that area though?,but i need to know if its normal if you take the 2 middle bolts out to have oil on them?,i havnt taken an intake off for a while so i cant remember?....looks like it might be coming from the lifter valley maybe?,no issues whats so ever,just had some oil sitting on top in the crevasses in the pic.
 
I do not remember any bolts going into an area of pressurized oil. And I do not think there are any oil passages through the intake to head surface. That indicates to me the bolts are getting exposed to oil from the valley though a gasket. You may be looking at a new intake gasket set soon. The steel core ones with the right sealers are where I would go after reading so many old posts.

it sound to me like there is excessive positive pressure in the crankcase, is your PCV system operating properly?
as far as i know yes ,ill double check,lets just say those two bolts were a little loose?,would that give me that issue?,i dont have any water leakage or any water in the oil?,runs great?
 
t
Like I said , retorque all of the bolts and see if it stops.
thats what im going to do thanks,after sealing them,i dont see any more oil....now,i did take the 2 bolts completely out,and i put sealer around the inside of the heads...do you guys think i contaminated the fluids now by pulling them out?!
 
Next time you just want a comforting answer, please tell us ahead of time and I can give you either the best case scenario or a complete line of hooey. Your choice. Yes, you may stop the leak for now, and it might be OK by just keeping an eye on it for quite a while. But I found retorqued, leaking gaskets eventually leak again.

Here is what you may have wanted to hear. The valve train fairy spilled a little oil while keeping your rocker arms quiet. There is nothing to worry about.:D
