Getting ready for the engine work- Did I miss anything?

[NC_John]

I am pulling the engine out just to reseal it (all new gaskets and seals), clean it up a bit and maybe give it a coat of paint. I got my box of parts in from Summit this afternoon. Here is what I had come in:

Intake gasket set
Oil pan gasket
Valve cover gaskets
Timing cover, with front and rear mains, fuel pump gasket, other small gaskets
New oil pump and pickup (will tack weld pickup to pump)
Freeze plug set
New timing set (chain and gears)
New Edelbrock fuel line (just to get rid of my butchered one)

I have a "new" '67 intake I am getting hot-tanked and cleaned up and am waiting for my Chevrolet scripted valve covers to come in (getting rid of the pcv and other vacuum plumbing on the intake).

I just realized I ought to get some exhaust gaskets (and figure out what I am going to do to the manifolds...paint them I guess)

Anything else I should do while I am in there? I have a brand new carb and brand new distributor, new plugs, new wires... I might get a water pump. The fuel pump is pretty new and easy enough to change if it gives me trouble later. Same thing with the starter. Its working fine and easy to change so I'm inclined to leave it.

I'll convert the throttle assembly to cable while its out.

I am trying to decide if I should get the rad looked at/tested while it is out or just leave well enough alone and give it a fresh coat of paint (using the eastwood rad paint). Same thing with the tranny (3 spd). I'm going to replace all the clutch and shifter wear parts (see if can get rid of that sometimes sticking pedal) but don't know if I should get it checked out at a trans shop. My thinking is its working fine now and I don't want to put money into a Saginaw I may replace later so leave it. If it does break I can pull it out easily at anytime anyway.

Am I missing anything? As soon as I finish an interior project on my wife's truck, I am going to start teardown on mine I think.

Maybe change the gear oil in the trans and the diff. Getting the radiator checked can't hurt and could save you some trouble down the road. What are you going to do to vent the crankcase if you are getting rid of the pvc system?

[kwmech]

Hope you are 'upgrading' the PCV system otherwise it would be a waste of time replacing all those gaskets

[brad_man_72]

Unless you have a road draft tube and a breather on the intake you really need to keep the pcv setup. If you have a breather and no draft tube you will just have an engine covered in oil mist.

My '67 (pictured) has it's PCV in the oil fill tube. The fresh air vent is in the rear of the block.

I'm using the '67 intake because its got the big breather/oil fill tube up front to vent the crankcase.

It has it.

Already done the trans and rear end. Using the '67 intake because it has the breather tube/oil fill so I can run the cool valve covers (like delmo does!)

Tell me about the fresh air vent at the back of the block. I have the tube up front and am getting the breather cap for it. Got any pics?

Don't forget to put silicone on those center intake bolts to keep that oil from pooling up on the intake.

[sean1969c10]

The oil fill tube and breather are only 1/2 of the system. That is where fresh air is pulled into the crankcase. You need either a pcv controlled vacuum source or a road draft tube. I am a little foggy on what Chevrolet used in the mid 60's as far as pcv goes because I have never had an intact unmolested early small block. I'm pretty sure Road draft went away in the early 60's. If you don't have a way of pulling the pressure out of the crankcase, it will find it's own way out via leaks. Simply having the breather on the fill tube isn't enough. I'm sure someone will chime in on the early pcv systems, I am interested too, I have 3 or 4 early intakes that might be cool to use one day. Make sure to post some pics when you get it back together!

I've never seen a stock setup either. I was actually thinking about putting a vacuum pump on there but (at least at Summit and Jegs) they are $$$! Maybe I'll go ask Delmo on his blazer thread. He's the one that gave me the idea.

I maintain a little puddle of oil under the carb now. You mean that's not a factory option?

[NC_John]

Sh*t. I think I might have just found a problem. I don't remember my 350 block having an extra fitting in the back for ventilation. I always figured the blocks were the same casting and just machined different for bore size. This is a pretty big difference right here that has got me scratching my head as to if this is going to work for me.

Glad I don't have much money invested in this ($60 for intake, $80 for valve covers) but I'll be pretty disappointed if I have to go another way. Nuts.

ADDED: I wonder if I can mount a pair of PCV valves at the rear end of the valve covers (back at the firewall) and run them to the back of the carb. It might just be a matter of drilling a hole into the back of each and getting a grommet. But then how do I keep oil of them- might not have room for baffles... Hmmmm.....

[NC_John]

Ok, so a little more research shows that edelbrock sells one of their performer intakes with the oil fill and breather to allow "old school" valve covers. They make no mention of the engine requiring any other breathing. Hmmmm.

I just have an intake filler tube on my boat engine right now. I'm constantly cleaning oil off of my engine. I was thinking about making a hidden pcv setup. Pcv and baffle under the back of the intake plumbed to the bottom of the intake routed to under the carb.

This thread is way to long to not have any pics.

are you making her paddle so you don't get that oil on the engine?

Nice Flatty

Sorry I forgot to respond to this question.

Here's a pic of a '67 block and you can see the fitting for the crankcase breather. From the factory, a hose would have run to the air cleaner base.



I seen pics of PVC valves run to this location and a vented cap in the oil fill tube.

With the hood off engine out it makes it easier to work on the heater ducting and core if any work is needed. Also easy to throw some paint on the front crossmember.

[WIDESIDE72]

I have seen pcv adapted to the rear of the valve covers somehwere on here. Pre pcv blocks are in Fact different. No rpivision for road draft tube on pcv engines.

Is the only thing you are after is to tighten up the seals on the engine, then you have everything. If it was me, I would take into account how many miles on the engine and how much of it was rough driving and look at the bearings on it while you are there.

Nice- I just PM'd him and asked if he was interested in making any of those to sell.

I found a baffled PCV grommet at Classic Industries that might work. Another option is to get and install an air/oil separator which would work great, but the added apparatus and plumbing might defeat the purpose of doing this mod in the first place.
