I would go with an SV pump regardless. The pan is your choice.

What was the purpose of choosing a HV pump? Reason being if your builder told you to do so then perhaps the bearing tolerances are looser than normal. Your builder should have a build sheet to tell you of such things.

Yeah so they tracked down my build ticket and they stated that it was a melling 155. He said it was pretty much a replacement for the stock one....So what the hell now? Is this a shitty pump? **** sake I hate my ******* life, lol! Pay all this ******* money to people and then you get a problem child back! What the ****! For Sale a 94 Z28 Camaro that has about $4K in the motor that has 250 miles on it that has full supsension. I'l damn near give it away. It's the one in the avatar!

Just put a standard volume pump in it.No restrictors or fancy pan.Change that pump or you will be sorry!

There is a 155 SV and a 155 HV. It seems you are not going to know which it is unless you look at it. I just can't imagine an SV pump pushing too much oil to the top. The only other thing I can think of is if they might have done something to cause drainback issues.

Could be a windage issue. Not sure if it was asked, but how many quarts are you using and what filter? If the stock pan was used do you know for a fact the builder bolted the windage tray back up?

94BlueZ28

Yes, the windage tray was used for sure because they asked me if I wanted it installed back on there and led me to belief that it would be best to keep it so I said yes to keep it. As far as oil and the pan, I'm running the stock pan with a tall boy FRAM filter because I got rid of my oil cooler. I can tell you the # on it tomorrow all though the filter is not going to cause this issue in my opinion. What kind of drain back issues are you talking about. I was told to check the head gaskets to as the holes might not line up perfectly in the corners of the heads if this is what your talking about. At this point I have no f***ing clue! Having the filter cut open tomorrow to see what is inside!

What weight oil are you running? How much bearing clearance do you have? Fram filters are junk.

I'm running 5w30, should I change this to 10w40 or some ****. I'm going to run royal purple from this point forward and grab a better filter like a k&N filter or some ****

Maybe try 10w-30? And yes change that piece of **** filter. a fram exploded on my moms ford exploder a few years ago going down the highway...along with a screaming dash

put 7 qts in it problem solved...ive rebuilt stock motors and done to same thing...my built motor also...7qts for 6 years now..no problems

If you are having a starvation problem caused by a high volume pump the thinner oil will actually find it's way back to the pan faster. Thicker oil will make things worse. If your bottom end is not too loose you will not have any issues with running lighter weight oil. That said, if you have a high volume pump I would change it for a stock pump.

You are joking, right?

(Or at least talking about a deep pan?)

how many quarts including in the filter?

94BlueZ28

iTrader: (34)

Well my dip stick shows completly full and I used I think 5 and half to 6 qts. My last oil change was in sept before I went to texas for 2 months so it's been a while so I cant remember exactly. Normally i'm right at about 5 & 1/2. So that's what more or less a qt in the filter, while running, a qt or 2 up top and then some in the pump and pickup so that leaves about 2 qts in the bottom. Do you think that this may cause it to suck dry.

SS RRR

iTrader: (2)

No I think you may have windage issues. Try putting in 5 quarts exactly and see what happens. If your pressure does the same thing then drain a half a quart and see if the same thing happens.

What will this tell me except that I'm low on oil on the dipstick! Not sure how the whole windage tray thing works or how that good be bad or what not! What should I look for when I drop the pan?

If your oil level is too close to the crank the wind from the crank can start agitating the oil to the point of cavitating the pump. Lowering the oil level moves it farther away from crank and if the agitation or windage ceases then you know you have a windage issue. The fix would be to use a different windage tray.
I had windage issues with my stock block engine ever since I owned it. Whenever I would accelerate my oil pressure would stop at 40psi. I just ignored it and never had any problems because of it, however in no way am I telling you to ignore this.

hate to go back to this but if that pickup is on the bottom of the pan you are going to have a supply problem. On the other hand if they did not really braze that pick up to the pump and someone put the oil level sensor in before puting the pan on, or if they hit the pickup putting the pan on your pick up could be just bellow the damn crank sucking air.

I got the block back and then installed the oil level myself. Everything was together when I got it back except for the oil level and that's becasue I had to get a new one because I broke it when i tried to remove it! Ive never had an issue before with the stock windage tray! I'm just going to remove the damn pan most likely next weekend and take a look at it. My luck is everything will look just fine and I will have no clue what the hell I'm doing. What is the clearnce i should have between the pan and the pickup???? What is the way to check thi, by clay? We have snow here so I cant take it for a ride to see what the effects are of adding a qt or taking away a qt. I'm pretty much fucked at this point unless someone lives around my local are that has a clue. I should just pull the motor and throw a big block in that bitch and be done, lol!
