1G Another way to feed oil "TO" the head?

[black_red_rs-t]

I am having a oiling issue. My head gets oil but its definitely isn't enough. If I take the oil cap off with the engine idling I get a few small splashes up out of the hole. It is to the point that my lifters can't fully open the valves. I do have have 3g lifters and wasn't having a problem until recently "re-assembling" my motor. By the way, its not enough of a lack of oil to create any lifter tick. It just runs a little choppy and boost is limited to the small amount of air that my valves are allowing to enter and exit the head.

With that being said, does anyone here know of a way to feed oil to the head besides the head stud hole in the left front of the head (standing in front of the car)? I'm almost positive that I have a blockage in the feed from the block to the head because it wants to run too good and my oil pressure never really drops besides the normal amount associated with the engine warming up. So I'm positive I haven't spun a bearing or anything. I currently have approximately 60 miles on this new crank and bearings and I don't want to kill my turbo. I know it can't possibly be getting the oil it needs If the head isn't getting sufficient oil to run correctly.

Thanks. Any insight would be appreciated.

Has your head ever been milled? I believe there is a port that can be opened up a bit to allow more oil to the head.

Did you have the oiling port mod done? That may help.

If not the only thing I can think of is to go electric oil pump/dry sump. Though I think that is really a race only type of thing.

Perhaps switch to a synthetic 0w-30?

No i haven't done the mod and yes the head has been milled quite a bit actually which is probably the whole problem. I have to run a .080 cometic head gasket.

Read through this, it may help.

Thanks for the fast and high quality of responses. I saw both of those while searching before I decided to post. I was hoping to not have to pull the head back off and do those but I know that it's probably the best way to go instead trying to make a shortcut.

I just talked to my machine shop and they will open that hole up for me for about $20. So it looks like that is my plan for after this weekend. I will post back here and let you all know if that fixes the problem but I'm sure it will. Thanks again.

Sounds like you have a solid plan. One thing I have learned with these cars is that shortcuts tend to cost more in the long run.

If you find your still running into issues, you might want to do a bit of reading at this website I am gonna link. If your engine is passed the breakin period it might be time switch to a synthetic oil. 0w-30 might sound like a bad idea at first, but if you read the article it explains why/how synthetic oils behave differently that mineral oils. A "lighter weight" synthetic will help you out at start-up, and behave just as well at operating temps.

Alright thanks. Unfortunately I'm still in the "break-in" period. But knowledge isn't a bad thing to have. I've learned that from experience. Lol.
