formula18 put his question in the wrong forum. Perhaps Ray stays out
of that one.
"Do It Yourself, Boating on a Budget" is here for a reason. With that in
mind though could Ray be sweeter? Sure. But I believe he has helped
many more people than he has hurt their feelings. Sometimes
certain people need a kick in the nuts to focus their attention.

No I don't think formula18 is one of them at this time.
P.S. Ray - the K&N filter you told me to put in the valve cover seems
to be working. I know it is just a band-aid but that's all I can do for
the moment.

does anyone have pictures of these plugs? when i put the timing chain cover on i remember there being openings going into tthere...i just figuerd it was to keep the chain lubed...
ps... guys thanks for your support and your help...still searching for an answer on the very low flow...oil is flowing correctly just at such a low flow

i will check those thank you...i spoke with my engine builder...who built the longblock...he is sending me a new oil pump a high volumeone so hopefully that works...i will check those plugs as well..
I tried to take a video of the drill spinning with the sender out...it does pump out just not with the flow you guy describe...i feel like its losing pressure somewhere...as it won't read on two gauges or reach the rocker arms
if i hold my finger over the sender hole...should i feel pressure against my finger?

Not sure with a small block (haven't seen one in a while) but with a 454 there is plugs by all the red arrows. There is also a couple plugs on the back but if they were leaking you would see oil pouring out the back of the block.

PS, I do it all myself. If I had to pay someone to do everything I do there would be no restored raceboat, Monza, Nova 19, Larson, etc, etc. They would all be filling landfills by now. Hell that's why I moved to floating pins on pistons. Even though they cost extra (30 bucks) i don't have to pay 10 bucks a piston to have them pressed on and wait the weeks until the get to them.

I knew I would piss a few off here with that reply and you are right, I am not here to piss people off. I have always been here to help and suggest and contribute to the sport.
So I will just say that in the future I will keep my opinions on subjects like this to myself.
However, I refuse to take my time to run basic engine rebuilding 101 here on OSO. If a boater who is doing engine rebuilding on SBC's and BBC's and he does not even know what and where the oil galley plugs are, he's way over his head and its not my job to get him out of a mess he should never be in. Nuff Said!
Best Regards,

Raylar, I think you are missing the point. Yes it’s true that some people should not be allowed to check their own oil. And yes us novices screw up a lot. But in my case if I didn’t try and succeed on occasion I would have a sailboat. I cant afford to pay you all professionals for everything. And it has to be said that you professionals screw up a lot also and I don’t care how “professional” you are. A lot of motors go boom every Sunday and I’m sure Jack Roush or Rick Hendricks knows a bit more about engine building then the local race motor builder does. Hell I’ve gotten things from local shops that made me scratch my head and wonder what the hell were they thinking. So then you find another shop and maybe by the time you are my age after a bunch of tries and a bunch of wasted money you find a shop that is good and wont rip you off in the process but now you have to worry if they are going to close or retire and then you are back to square one. Not everyone can do that.
There is times that you have to throw in the towel and go to a professional. I gave up on an 1970 Johnson 6hp outboard this summer and bought a brand new Tahatso (sp?) 6hp but for a Chevy small block? They should be the motor that anyone who wants to know about motors should be working on.
All I really have to say is yes there is a lot super nice boats on here. Just look at some of the poker run pictures. 30, 40, 50 foot boats with more HP then all the cars on my street put together. But there is also some folks like me who want to learn from you. And I’ll tell you, A couple years ago I put a motor together that had low oil pressure and then filled with water. A finger tight head bolt will do that. Crap happens.
Formula18, I would either start the motor or take it back out. Some thing is wrong. I’m sure it’s simple but it’s wrong.
Also I may have missed it but was this a simple refresh or was it rebuilt for a reason?

thanks...its a rebuild with a different block than the first one...
im goign to pull it...i just removed everything...going to pull it this week...
and as far as raylars comments....i wouldnt know of the plug becuase i didn't build the motor...im simply bolting on accesories and simple things...i had the long block built for me...should be simple enough...unless something is wrong and obviously it is...
if you don't want to waste time helping someone thats wants to learn from someone one this site then why are you on it wasting your time on this thread...im sure you started somewhere???? you werent' born knowing the ins and outs of a small block...maybe i would like to eventually be able to rebuild one myself...right now i just don't know enough and am struggling....everyone else thank you so much for your help...ive been posting here for a few years and everyone is so helpful...

I have built some motors but am far from an expert. But I am mechanical engineer and know some stuff about positive displacement pumps (what oil pumps are) and the odds of it being a "bad" pump is very small. Unless it is BONE dry it will self prime as long as it does require much "lift". I am betting on galley plugs being left out because ****z happens. That being said , I can totally appreciate formula18 wanting to learn and budget. IMO the professional builders have their place and I respect their craft, they know more then i could ever dream of. But they also didn't invent the ability to rebuild something adequately.
I think some professionals do get frustrated by Mr. Fix it types but you have understand that there are some very capable folks that enjoy doing their own stuff for a variety of reasons. I once had a guy that runs a local shop (and a very good mechanic) that engineers are worst customers because they fiddle. He didn't know me from Adam, I have built everything from 11 second Volkswagens, numerous automatic transmissions and designed and build some space hardware that is above us right now on the international space station. He told me I cant tune up my boat properly because I am not a trained tech. Really, that's kinda interesting. I challenged him to he choice of whatever troubling shooting contest since obviously I am "worthless" in the marine world........
Raylar, I say either make a genuine effort to help the thread author or be secure enough to go about your life doing what you do very well.

Formula.....maybe you're farther along by this point, but something escapes me from this thread.
If they left a plug out, it would be in one of two most likely spots.
1) Either at the rear and you would see oil dripping out of the bottom of the bellhousing when you are priming the pump (oil in the bilge).
or
2) it would be at the front behind the timing gear. Have you removed the timing cover and tried to prime the pump and see if you have oil flowing down behind the timing gear?
There are also oil gallery plugs externally right above the pan/block joint. Of course, if these were out, you'd have oil in the bilge just like in Option 1.
Before you yank the engine, have you ruled out the things you could fix with the engine installed?
When I primed by BBC's just a few weeks ago, a Hitachi cordless 1/2" drill was all it took to get 60psi on the gauge.
