Seems like I'm having all kinds of problems with this block haha. Anyways... on the front of the bare block, right about the front crankshaft journal there is this pin that goes into the block. It is this one the arrow is pointing to:



On my other good block, the pin is there and ok, but the one block I'm working on now, the pin has broken off somehow (before I obtained it) and leaves a hole there. I took a compressor and blew air through the hole, and I can hear air coming out of the oil filter block, but no where else. On the good block that still has the pin, I don't think it is open, and the pin seems to serve no purpose.

Does anyone happen to know the purpose of the pin? It seems to be connected to the oil ports within the block, but it is blocked off... I don't think it squirts oil anywhere or anything, and if it did the oil would just hit the timing cover and go back down into the oil pan.

However, the block that I am working on the pin is broken off, so I am assuming the hole there is going to allow oil to shoot out, but my main question is, is it really going to cause problems? The hole is not that big that I don't think it would affect oil pressure or anything, would it?

it oils the chain. without that, you'll have really low oil pressure.

bumping ~6 hours after your initial post is really poor nettiqutte. get over it.

well excuse me for being in a slight hurry not having a lot of patience, i dont have much time during the week to get things done, a harmless bump and the sooner someone can answer the faster i can get more things done. its not like im starting more threads on the same topic or constantly bumping the thread all day, im keeping it in my own, and id say 6hrs is a decent amount of time thank you very much....no need to get panties in a bunch and say "get over it"

anyways, how does it oil the chain when no oil ever goes out of it normally?

i took a look at it again on the good block, and i noticed there are no holes what so ever on the pin, but did notice 2 scratch marks that i would assume the timing chain caused on it. the pin with the timing chain installed sits in between the 2 chains (not 2 seperate chains, but the two halves i should say), but not touching either one. im assuming the chain marks on it are from when the timing chain guides broke in the past

or it could serve a purpose to stop the chains from hitting each other as the tensioner loosens and tightens? but i dont think the chain ever gets that much slack...mysteries hehe

6 hours, your post is still on the front page. this is not just a nico deal, it's poor nettiqutte everywhere. there are other folks with problems bigger than yours. also you're waiting for OTHER people to post up what that is, ie they're doing you a favor.

it's an oil jet. it has a punched hole at the bottom of it where it jets oil onto the chain and sprocket.

You need to get that replaced. ask for a timing chain oil jet. it shouldn't be more than 10 bucks even with extraordinary dealer markups.

i thought that pin was there for dialing in the timing assembly. I'm at work and can't check my FSM right now, but I will check it when I get home

that timing pointer pin is on the outside of the timing cover, this pin we're talking about is inside it on the block.

think i found the hole hehe.... how am i supposed to pull the broken one out?

the oil jet, did it break off in there? you can try using a reverse drill bit to try to get a grip on it and then pull it out straight, otherwise it's going to grab the side and you're gonna be cussing that you'll have to do the setup again.

If it did not break off, then you'll be able to grab it with some channel locks or normal pliers and again, pull it straight out. you can try twisting it a little bit to help ease it out, but not too much otherwise you might go off of 90 degrees to the face of the block.

unfortunately... the pin broke flush with the block. i figured i was gonna take the oil pin out of the other block and put it on this one... but i have no clue how im gonna get the broken one out hehe.

is it just pinched in the block, like no threads or anything?

(by the way, i apologize about the bumping thing and the comments, its just a simple "bumping ~6 hours after your initial post is really poor nettiqutte." would have been fine, but come on a lot of people would take offense to the "get over it" hehehe)

appreciate the help

It's actually quite smooth. Therein lies the problem. Because it's smooth, it's a very tight fit to be able to hold back the oil and keep the oil pressure on the up and up. So you will need to pull it out very much straight. You can also try using a small tap and then using a slide hammer with a very small adapter.
