oil pickup tube not lining up

[1Gina2G]

So today I began assembling my shortblock, starting off with the oil pump front case & oil pickup tube so I can get the oil pan on.

After bolting the front case to the block, I put the oil pickup tube where it should meet the front case, and the other part where it straps to the crankshaft case with a single nut, does not line up.

If you connect the pick up tube to the crank case, it won't line up to the front case, I'm stumped because the oil pump front case is perfectly flush with the block.

I was wondering if I could just cut the other part of the pickup tube that keeps it in the block, to make sure it doesn't get in the way of the crankshaft? Not sure why it won't line up now, the pickup tube can't bend or anything.

Are you mixing up 6 and 7 bolt parts? The front case, oil pickup, and pan are different.

deffinatley not, it's most deffinatley a 6 bolt front case and oil pickup tube.

Alright, after going over everything again, I didn't get it to fit still, and this is a bigger problem than I thought, so now I'm really clueless on what to do.

The front case is matched up to the block by the 2 dowell pins in the block, and it is also flush with the block on the oil pan side.

The crankshaft caps are lined up with the block, and correctly bolted down how they should be, but the cap closer to the front case with the stud for the oil pickup tube is slightly lower and to the right of where the pickup tube wants to be.

I was going to just cut off the extra part on the pickup tube, untill I realized the way the pickup tube wants to sit on the front case is actually HIGHER than it's supposed to sit. How could this happen??? I can't figure out how to solve this problem, as I said earlier the pickup tube is not bendable, I already tried to bend it, and it dosen't budge.

I already tried taking off the front case twice, and it only goes on the block one way because of the dowel pins. Yet, for some reason, my oil pickup tube wants to sit an inch higher almost so that the oil pan can't bolt on now

Hmm thats weird is the pick up bent at the arm?

Where did these parts come from and were they bolted together before? My only guess if you have to have inadvertently gotten some six and seven bolt parts mixed up. There is no separate part number available for the pickup tube portion of the oil pump so I can't tell from just part numbers if the parts are different. I wouldn't be surprised if six and seven bolt rear parts would interchange but something is different. Is the entire oil pump assembly new? More information please.

Something is probably bent. I would use new oem parts to begin with if you are not sure. This will save you a headache.

Like I mentioned, everything was deffinatley 6 bolt. They were all bolted up together and used before, all these parts were hardly ever used. 6 bolt block, 6 bolt oil pump front case, 6 bolt oil pickup tube, 6 bolt oil pan ect.


I'm still stumped as to how this happend since they were all put together and I disassembled the block. I put the pickup tube in a bag like everything else...I don't think it's bent, because it won't even bend if you try to bend it.

I ended up bolting on my spare 7 bolt oil pickup tube to the 6 bolt front case and the clearance works out now in both places I was worried about. Still slightly worried why the 6 bolt pickup does not want to match up, but everything else is %100 so I guess I'm going to finish up this assembley and get on to the timing

 

[pauleyman]

6 bolt and 7 bolt pickup tubes are different part number. I don't have two to compare but if the differences are in mounting and you put a 7bolt tube under stress it could crack under use. I think you should still investigate the root cause. I have a 6 bolt here and the flat of the flange if you look across it the bolt is almost in the same plane, relatively. Different angle but very close to same plane. I' m not 100% sure the two pans are the same depth either since the 7 bolt has a dip in it. Clearance of the pickup end could be an issue. Worth comparing.

you can't bend it? Doesn't look too far off.

I'd say it's for sure that these oil pickup tubes are not going to bend without some serious force/impact without any welding. They are very durrable, something deffinatley appears / sounds like it's bent, but I'm still puzzled to what it is.

Even though I ended up getting the 7 bolt pickup tube to fit for both clearances (crankshaft & oil pan) I ended up taking everything back off since my front case ended up being bad from a worn out oil pump sprocket stud. The seal facing the inside the block also needed to be replaced, so I just ordered a brand new front case & sprocket, so hopefully I'll get lucky with this new one and the 6 bolt pickup will fit, and I'm really hoping the sprocket will go on easy this time, since I could not budge the new sprocket onto my current front case

 

[pauleyman]

Elaborate on this sprocket please. No sprockets bolt to the case. They bolt to parts that stick out of the case. Front balance shaft, crankshaft and oil pump shaft. Which one was bad?

Any pics?

That's what I meant, the part where your suppposed to push the oil pump srocket on-to is worn out since it just won't go on strait. This sprocket has got messed up twice on me already on this front case because I never threadlocked the nut and I know this front case is just worn out now because of that part. Not saying that has anything to do with why what evers bent though. hopefully I'll get lucky when the new front case comes in.

what would does anyone want me to take pics of? front case?

 

[jimbob_843]

Mine didnt quite line up either, wasnt that far off though. I just beat mine on with the pickup bolts loose. Ive seen plenty of pics floating around where people just cut the support off. I assume this is common because of arp fasteners. And i dont think the support is really necessary, the 7 bolt doesnt have one.

 

[1Gina2G]

the new front case came, I put the oil pump sprocket on first, and it fit right on perfectly, glad it came with the nut too, which I threadlocked.

for some reason my 6 bolt oil pickup is still not lining up, so I just bolted on the 7 bolt and started putting on everything else, I plan on doing my first timing job this week, then get the engine in soon after
