I got a 330 running that has sat now for 20 plus years. At first this old thing ran real rough, but cleared out. I was supprised to see that it had no smoke at all, but that changed after about an hour of running. First no smoke then it smokes and stopped, started and stopped a few more times, but now it will not stop. BTW it is white/blue oil smoke, and has blow by now too.
I think it could have broke a ring ??? any ideas?

Rickman48

Rings fell apart, and valve seals crumbled, would be my guess.
I'd have let it sit in MMMO for a few weeks, used high-mileage oil and fresh gas.

kjr442

Well I did the fresh gas thing, and changed the oil. I even pulled the timing cover the take a look at the gear and chain. This engine looks new inside, right down to the nylon coated timing gear, no cracks or loose chain.
I was optimistic about it because it was a 52,000 mile car when it was wrecked, and parked years ago.
what you said makes sense though. Do you think it could be just the valve seals with only 52,000 on it the rings might be ok????

oldcutlass

I would venture to guess valve guide seals, they are inexpensive and relatively easy to change. Also if you perform a compression check dry, and then with a few squirts of oil wet, it will tell your the condition of your rings.

Make sure the PCV is working correctly.

oldstata

On my 330 the PVC was by passed and it was smoking really bad and spitting oil out the oil fill tube

Once I installed PVC quit smoking and spitting oil out the filler tube I wouldnt have thought it would have cause that much smoke or oil spitting
Just my experience

Well I don't think it has a pcv valve , I know it's not at the valve cover. Where else would it be on a 65 cutlass?

oldcutlass

Do you have a picture of your 330, the PCV is usually on the passenger side valve cover. There will be a breather on the drivers side.

oldstata

Mine it should of been on right side (passenger side ) but was replaced with a breather the left (driver side ) had no hole for breather or PVC with the OE valve cover

kjr442

Thats what mine is.

kjr442

I think it is the valve seals, but I will disconnect he trans, vacuum line to see if that could be pulling oil from the transmission. I will keep you all updated.

oldstata

If it has the breather instead of PVC ,I would replace it with a PVC ran to carb vacuum .thats what I had to do to get mine to stop smoking


Might not be the problem but it's a 5.00 fix That should be done anyways

oldcutlass

The 330 definately needs a PCV as they age. Without it, it will spit oil out of every open oriface.

Looking for engine and transmission for my 1956 Oldsmobile Holiday 88,thanks Andre.

Mine sat for 35 years, I couldn't get the Carter AFB's to rebuild but the Eldebrocks fixed the problem, I changed my old three tiimes for the first few hours to clean it up, seem to be better. I'm going to drive it for awhile then start underthe hood with restoration

oldstata

You might want to start a want thread and list your location and what you are looking for

I am in Utah and I know where a 330 and jetaway trans but that might not be what your looking for

kjr442

I live in Texas, if you still need a engine and trans, let me know.

kjr442

Well guys the pcv valve worked, I don't know how or why,but it quit smoking totaly. My question now is this just a bandade, masking a problem that should be fixed?
These engines never had the PVC , and this is a low miles car so why is it needed now?
I know it sounds like I'm looking a gift horse in the mouth, but if it needs something I would rather just do it now, before I go through the trouble of putting this engine in the other car.

oldstata

I am pretty sure they came with PVC I recall seeing it in the service manual

But you also need to think about fuel and oil changes over the last 50 years
I am not one to know exactly how these changes affect things but I know they do

Your 330 had a factory pcv valve. The feds mandated all cars be equipped with a pcv system starting in 1962.... CA did in 1957. No more road draft tubes.

You MUST run a pcv valve or face blown seals and gaskets...

kjr442

Only the passenger side valve cover has a hole in it, and it had a filter in it like my other 330. The hole size is way to big for the pcv, so I rigged a addaptor for it for now. Where would the factory have put it on the 330's ?

oldstata

Mine it should of been on right side (passenger side ) but was replaced with a breather . left (driver side ) had no hole for breather or PVC with the OE valve cover


Not sure why people replaced them with breathers ,but they do

kjr442

I am not convinced, both of mine are the same with a large opening in the grommet, much to large for the PVC valve.
If the 65's had the PVC I would like it if someone could tell me where it would have been installed from the factory so I can put it back like it should be.

I just looked up it shows three different PVC for the different engines for 65 330 400 and the v6

oldcutlass

Take a picture of both valve covers for us. Like I said earlier, the pcv would have been in your passenger valve cover, and a breather in the drivers.

kjr442

I will do that, but both of my cars with 330 have no opening for anything on the drivers side. The passenger side has the grommet like my 350 , but the hole size is to big for a PVC valve so used a adapter for now.

kjr442

Cool, thanks i will look it up.

Here's a link to a pic and a part number of the PCV valve.

kjr442

I have gone back to the filter, no pcv . I found the problem, the drivers side exhaust manifold has the stock warm up flapper in it or what ever its called. I figured out that it was stuck shut and causing crank case pressure. As things stand right now, I can't make this thing smoke, or blow oil from anywhere.

64OLDSPILE

Cool!

Yeah mine runs like a watch, pretty amazing.

oldstata

I would still look up the spec from Wildaboutcarsonline
The diagram showed a filter / valve it ran from the valve cover to carb and air cleaner on the 330 with only one hole valve cover the two valve cover had one breather on pass side and PVC on driver

I still believe that you should have it unless its the factory one you have and I am just thinking of a breather only

krooser

The 'flapper" valve is the heat riser valve... it can not build up any crankcase pressure.

Again... if you car was built in 1962 or later it had a pcv valve... and needs one. prior to '62 all cars had road draft tubes to ventilate the engine.

kjr442

Well then I guess it's a big mystery, for what ever reason it is cured
I'm cool with using the pcv , Im just running on curiosity for now.
Thank you all for your input on this , I really do appreciate it.

[except 1968 models]

If you have a hole in each rocker cover, these holes will be identical, and "D" shaped.

One should have a simple flattish grommet with a 63/64" hole [that's 1" to you folks in Rio Linda], and takes a push-in filter which either vents to the air [pre-68] or thru a steel tube to the air cleaner housing [1969+].

T'other hole sports a SPECIAL GROMMET that holds the PCV valve. It's pricey now for a real one.

Aftermarket units, in my experience, do not fit right and in fact may not even accept the proper PCV valve. Poor fit.

im willing to bet that the rings are busted and that there is allot of uneven wear in the bore. also chances are the valve seats are pitted fairly bad and aren't sealing up properly. with an engine that old i wouldn't rely on it for driving all that much. it'll take about an hour to rip that sucker out, and about a half hour to tear down..

kjr442

It runs clean now, no smoke.

krooser

I've had quite a bit of luck over the years with getting long dormant engines to rise from the dead.... good luck with that 330.

krooser

Well I just pulled my 330 apart and mine is way beyond just firing up and running it... complete rebuild time for me.

celodog

i work in a automotive machine shop with my father in law so naturally i took the 330 out of my 65 cutlass that i just got.. it ran fine, just needed new gaskets. but now im thinking i might want to get a 455, rebuild it, and stick that sucker in.. kind of torn right now!
