Projects Mid Life Crisis 62 Vette

This has been fascinating to follow along as to how the source of the oil migrating to areas where it should not be.
So far the solution has not been discovered!
I wonder if the revered wizard, " Smokey Yunick" if he was alive today, would have been able to solve this puzzle !
The automotive version of the game "CLUE" continues!

 

Jim, The part number is on the gasket. And it does end in 0322. The first number is either a 9 or 8 but I can't make it out on my Ipad. Could someone have switched the gaskets in the package? In any case, it could explain why they didn't work as you expected them to.

 

The 90314 intake gasket is the teflon perma-torque type...the 90322 I got is not.

If you can find some reference anywhere to it being perma-torque, I'll be convinced otherwise.

 

I am excited for you! Had looking to do same thing as you, find a '62 Vette and relive one of the most exciting things in my life. The Willys would have to go down the road to make it happen.

 

looks like that was a fun car!

 

Jumped the gun on calling them Permatorques, but the are definitely not for non stock AL heads and AL intakes. The integrated heat riser block off may be for marine or medium/heavy/industrial or alternate fuel use.
They are not 'performance' gaskets for use in a custom application.

Tried using Felpros site but its wonky/broken. Search function is not working for me, but I am on my phone atm so it could be that.

Either way those 90322s will not stay sealed properly against your current heads/intake.

Need to use the softer printoseal type intake gaskets that come with the elastomer rings around ports for proper sealing. One of the 12** series felpro intake gaskets, or other brand equivlants.

Those stiff graphite type gaskets are fine on Fe to Fe and possibly stock AL intakes, but not for your combo. They are unable to maintain seal from thermal movement of AL heads and AL intake.

 

They are metal core graphite...which is pretty common on modern stuff, that moves around. I went ahead and put them on and installed the intake, with Aviation 3 sealer around all the ports.

I ordered the Edelbrock 7201, will be a couple days till they get here.

I'm about to dive into the rocker studs next.

 

We used to use the Mr. Gasket intakes gaskets, they were thick & white. Soaked them in a bucket of water till they swelled up than installed, let sit over night, fire up.

 

Jim, do you have access to a smoke machine?
With the rockers and studs off, you could pump smoke into the intake and see if it's leaking...
Then again with the studs installed.

 

Squirrel, I am redoing a '61 Vette & have driver quality parts that I will be listing. Most parts are interchangeable with a '62. If you are missing anything shoot me a PM. Lon

 

thanks, there's not much that I need now....that I can remember, at least.

 

Playing with the intake gasket and rocker stud sealant didn't seem to do anything at all...went for 100 mile drive, oil level dropped 1/8", and the plugs are getting wet again.

 

Bummer

 

dang nabbit! Thanks for the update, but I can't bring myself to 'like' it.

 

Crap!... was that with your pcv connected or disconnected?

 

PCV was disconnected

 

I didn't read all 57 pages but leakdown test?

 

Umbrella or o-ring?

 

The new heads have modern positive seals on the valve stems....

I haven't done a leakdown test.

 

Jim I’m going to ask a dumb question. Are the piston rings installed with proper orientation ie: top to top?,the reason I ask is that it appears all cylinders are getting oil, I believe you ruled out intake gaskets and I can’t believe all the valve seals are leaking also ruled out pcv. The only other thing I can come up with is rings. A very strange conundrum indeed.

@Sharpone , he didn't touch the bottom end when it was pulled and 'improved'.
That's why I went back and found the point in this thread where the work was done.
This is the upgrade.

So it was good and didn't use oil for his previous runs, then he changed the cam, pushrods, rockers, complete heads and intake/carb. If something affected the rings, it got 'em all.
Jim is smarter than the average bear and when he's coming on and asking the HAMB brain trust, it's because he's thought of all this and is not sure on the root cause. It shows that any of us can get stuck and a willingness to concede he doesn't know it all. Kudos to him for putting this out here.

 

Thanks for the summary...yeah, it's pretty weird....

I've read about some other guys having strange oil loss issues with similar setups, no real solutions.

I'm about ready to put it all back to stock, and see how it does.

Oil consumption before the the head/cam change was about a quart every 2000 miles

 

Too bad you’re making the trip. By that I mean this. Install old school cone shape style valve springs and or modern beehive springs on the stock iron heads to work ok with roller cam and just swap the heads and see what becomes of it???

 

I wonder if the angle between the block surface on the heads and the intake surface on the heads is off just enough to allow oil to be sucked past the intake manifold gaskets. Another words it's not clamping the intake gaskets evenly, more at the top and less on the bottom so it sucks oil into the ports in the heads.

 

I’ve been following along but must have missed the original bottom end part, I agree with your assessment of Jim. Jim is one of the people I would seek out for technical help, and why I started my post with “I’m going to ask a dumb question” This issue intrigues and baffles me. The problem is something common to all cylinders I believe, the only other thing I can think of is the fuel pump. I’ve seen fuel pumps leak gas into oil but never saw one suck oil from the crankcase.
Good luck Jim

I had read an article before about oil consumption like this, it ended up being the intake manifold and head mating surfaces were off a little. The gaskets weren't squeezing quite enough at the bottom letting the vacuum suck oil. It does seem a dry wet compression test and leak down are in order. Good luck.

 

If you go back several pages you’ll see the new heads and aluminum intake unpainted on the engine. The fit looks spot on.

 

Thats why I posted #1688, nobody knows how much the block & heads have been milled over the years............................

 

Jim Said the intake manifold is not oily, only the ports in the heads and the gaskets are soaked in oil. So the problem has to be the interface between the heads and the intake, no oil above gaskets, only below. Can't be the upper part of the manifold not sealing or it would suck air, what else would put oil in the ports of the heads and not the ports in the intake manifold?

 

Porous heads is a thought.
