there is a hole close to the top on one side of the lifter. does it face up or down when putting the lifters in. i think it faces down but unsure. thanks.

 

?

The lifters only go in one way...not sure about the hole...probably an oiling hole you are talking about...

I would not worry about it---->oil lifters, insert into trays (only slide in one way, roller down) and slide into lifter bores, push down onto lobes of cam with pushrods, done

You're good to go..

there is 2 ways the lifters will go in. either with the little hole facing up (towards intake) or down (towards pistons).

 

the little holes on the sides of the lifters all faced the front of the car when i removed mine.

 

there is only one hole per lifter and it can not face the front. it can only be top or bottom

 

maybe a pic will help...there is only one "up" and one "down" with a lifter

hes talking about the sides of the roller, being able to rotate it on its axis and insert it in different directions.

I think he knows that the roller goes down....

 

yes i know the roller goes down.

 

You must be referring to the OILING hole, which I mentioned previously. That would be left and right orientation, not up and down...
That is why I was confused lol...

Orientation does not matter.

Oil will get there either way.

If you are concerned, you could always drill the lifter trays a bit to allow for more oil to come in...I never have, but you can.

 

this wasn't clear, sorry...

 

thanks for the help. i checked online at alldata and it does not say either. i also looked today on the gm website here at work and it does not say either. i was told by the tech that it does not matter either. i work at a chevy dealer and i knew it was a stupid question but i would rather be sure when it comes to stuff like that.

 

Hey. no such thing as a "stupid question"....better to ask than to screw something up!!

It is for this reason that the best athletes still have coaches helping them along the way!

Good luck
Erik

 

it doesn't really matter but I looked at the oil flow diagram and faced the oil hole toward the source of the flow.

 

Thank you "ERIK@MASPORT

 

Thank you DaddySS for your help.

 

"Erik" last posted in 2010, so he'll probably not respond...

 

It doesn't matter which way the go but i always face them up since gravity will bring the oil down.
