I set the valves (.21) and checked for leaks this morning. After everything looked cool, I bumped the key, nothing, advanced the distributer a hair bumped the key and instantly the beast came to life. :thumbs: After 10 minutes into breaking in the cam I noticed a pool of oil (about 1-1/2 quart) underneth the rear of the engine, so I aborted. Being that it only leaked when under load It's pressure related. It wasn't dripping but a steady run so I'd guess it's the rear cam plug. The oil flowed too fast for it to be a rear seal (unless I completely blew the rear 1 piece seal out which I doubt). I'll be pulling the 4spd, bellhousing, ect. off to see the problem. Other than that she sounded great, no rattles, strange noises, nothing.

I must say the cam has a nice lope to it, but nothing really radical. Of course I only brought it up to 2,500rpms at the most, can't wait to hear it at 6,500rpms. :D

So she's coming slowing but surely. :party:

Corey:
I know the sound you speak of all too well :) . I liked the sound so much that I never even bothered putting mufflers back into the side pipes. Good luck tracking down the oil leak...I'm sure it's nothing major :cheers: .

I just fired mine up last night, nothing compares to the sweet thunder of a BB!!! Hope you'll find the cause of that oil leak soon. :cheers:

hudman

I drove mine around for a week with open headers while I was having the battery box reglassed.

Sweeeeeeeeeeeeeet sound.

I am sorry. . . .what did you say?

When I had the Flowmaster 40s installed, I thought they sounded pretty wimpy. Everybody on the Forum had me so paranoid that they would be too loud. They are quite tame in my opinion.

:party: Glad to hear you got it fired up. Are you using the Felpro oil pan gasket? Maybe you have the same problem as Steve Straus.

You sound like Bence now...."This cam doesn't sound too radical." :D

Corey_68

Len, yes I'm using the "blue" one piece oil pan gasket. It's leaking from the block, so it's not the pan gasket. I'm 90% sure the leak is coming from the cam plug, it's NOT the rear seal which is good. I'll know for certain after taking everything off, I have a phamacology test Monday (a walk in the park for you I'm sure :D) so I had to shut it down for the day. Also since you are using the same pan and dipstick I wanted to pass some info on to you:

1) I had to put teflon tape around the drain plug, it had a slow leak
2) I'm going to have to cut the dipstick tube and dipstick. It's a generic tube (for all Moroso pans), and with a full pan (6qts) it hardly shows in the stick

So I upped the ante and fired mine up, so now it's your turn. :yesnod:

:cheers:

A Pharmacology Test??? :confused: What are you nuts?? :rofl: I think I'm getting a migraine again. :lolg:

Are you in Pharmacy School or Med school?

Corey_68

I thought about Med-School in the past, but a suck at physics and advanced Chemistry. :lol:

I'm 50% finished getting my Para-medic certification (my 3rd college degree :rolleyes:, I feel like I'm never going to finish school). I'm not wanting to work in the field (riding the ambulance) but I need the certification in order to be employed as a safty engineer for one of the major oil companies. My dad has 30yrs w/ Shell Oil, so he's giving me a little guidance on what to do/not to do. I'll finish up this coming Summer.

Great to hear Corey. Hope all goes OK. :thumbs:

Brettmc

Allright!! How much ya got left before the much-anticipated road test?

Brett :thumbs:

Corey_68

Come to find out it was the cam plug as I first thought, not biggie. Now, all I have to do is put the interior back together which isn't that big of a deal. It will take a couple weekends because I only have one day off a week, and I have to study for some of it. Hope to be driving by late October/Early November. :thumbs:

Corey, is that the 7 qt pan by Milodon for the Gen V & VI bb 'vettes?

LT1driver

yes the sound of power is awesome, when I cranked up my 427 with open headers for breakend the neighbors came over to worship the sound of power :D :D

Corey_68

No, I'm running a 6qt kick-out sump Moroso # 20411 for Gen V & Gen VI BB. I gained about 3-4inches in ground clearance over the stock 454/502 pan. :thumbs:

:cheers:

marky mark

Thanks for the info Corey. So, other than the dipstick issues any other problems? Any clearance issues with the headers, oil filter or anything else?

Thanks again, Mark

Corey_68

No issues what so ever, cleared the cross-member without any problems, great fit, and comes w/ the trap door and screen. You WILL have to purchase a new oipl pump pick-up with the pan though. No clearance issues w/ the headers (I'm running Hooker side-mounts), or anything else. The dipstick really isn't an "issue" per se, more like a "one size fits all" item. All I have to do is trim the stick a little bit, mark where 6qts is and I'm in business. Len (1970 Stingray) has the same pan execpt for a Gen IV BB, he had no issues that I'm aware of either. I'm really impressed w/ the Moroso pan. :thumbs:

Thanks again Corey!

I was wondering how deep the stock GM 6 qt oil pan is that comes with the 454 & 502 crate motors?

The specs on your pan say 8" deep. The Milodon pan says 8 & 1/2" deep.

I measured my stock Gen IV just now under the car (granted the iron heads are removed) and it appears to be about 7& 1/2" deep and a little more where the drain plug is. That measures to be 5 & 1/2" clearance to the ground. Add in the heads, intake, exhaust and maybe it drops to 5" perhaps less but I doubt it as I have a very stiff suspension.

My point is figuring out how much clearance I would have if I just kept the pan that comes with the crate motor. If say, the GM pan was 9 & 1/2 " deep then it might be tight to say the least. If less, maybe I can save the $ and hassle of having to change out the oil pump, pick-up, dipstick, etc.

Did you have the stock oil pan installed in your car at all before?

Thanks again. Sorry for so many questions.


Regards, Mark

Corey_68

Don't apologize for asking questions, that is what we are all here for. :thumbs: Yes, I had the stock 502 pan on, and with my #550 springs on the front, I was concerned w/ clearance. I don't think I would have cleared a speed bump w/ the stock pan. The Moroso is a better all around pan, plus it gave me a piece of mine about clearance issuse. If you want I'll take some pics for you to give you an idea how your car will sit w/ this pan?

:cheers:

marky mark

Thanks again Corey,

I forgot, in order to get my "stiff suspension" I spoke of ( consisting of the'Vette brakes Complete Street Slalom Kit) the car has been essentially lowered an inch or two already.

The Moroso sounds like the best pan. GM Perf dealers seem to be selling the Milodon.

What actually needs to be changed out?

1) Pan for sure.

2) Pick-up of course. Bolted to oil pump or tack welded?

3) Oil pump ? Sounds like the Melling M77 or Melling M77HV is recomended but that may be on a Gen IV. I know my first engine had that oil pump in it.

4) Gasket? Is this new Gen V/VI gasket re-usable?

5) What about the crank scraper? Optional?

6) Windage tray?

Then there is mention of main cap nuts. I assume for the scraper and/or windage tray. Does this mean you have to undo the main bearing bolts to install the scraper & tray? That seems a bit extreme so I guess there is some other method of attaching them that I don't know about yet.

Thanks for the help and offer of the pix. I don't think they will be necessary as your pan would only be adding a 1/2" to my set-up. That would not be a clearance problem. I would like to keep the standard BB Chevy starter/solonoid. Only other thing is I will be running the 1 &7/8" Hooker Super Comp headers under there. Car is a 4-spd, L-36, 1969 ragtop in need of a reliable motor.

I won't be responding to any answer tonight as I am off to bed.

Thanks for the help. I do appreciate it!!!

Regards, Mark

Congrats!!!!! Must be a great feeling, I wouldn't know. ;) Glad to hear you found the source of your leak too.
