Early 63 PCV

Re: Early 63 PCV

Good suggestion Joe. Maybe I can work the rubber grommet out of the sleeve and leave the sleeve in place. Have you seen this early grommet and sleeve out of the engine and verify if the picture I posted is accurate?

The picture is accurate.

By the way, why they thought there was a need for this 2 part grommet with steel sleeve is beyond me. Of course, they rather quickly figured out it was unnecessary and went to the second design.

Re: Early 63 PCV

The Sleeve and grommet assembly was used on many Chevy engines. Not just Corvette
When my 63 engine was re-restored by Boardman Machine in Boardman, Ohio the engine builder known as Pudge or Harrold had a puller to remove the sleeve without hurting it. Now that was in 2012 or so. John

Yes, I expect that all 1963 engines used the 2 part grommet.

I do not see why it would be necessary to remove the sleeve if one had a replacement for the early style rubber grommet. It only seems necessary if one is going to replace with the second design grommet.

Re: Early 63 PCV

John, Was the engine builder able to find the correct replacement or did he install the later design without the sleeve?

Thomas, He used the original over again. It had a log on it. GM and opposite of that it had the Letter RP jammed together. I had a NOS assembly until a few months ago. One of you here got it.

That NOS assembly had to be VERY old. The 1st design grommet was discontinued from SERVICE in March, 1964 and the retainer was discontinued in May, 1964.

Re: Early 63 PCV

Joe,
Do you think it would be possible to modify the later design grommet to fit tightly into the steel retainer with a couple of arch punches? Would have to reduce the diameter of the top and bottom sections of the grommet.

Yes, I think it would be possible. However, the main problem is going to be obtaining an arch punch of the exact correct size. Only one punch would be needed in order to reduce the major OD. The center hole would be the same and the lower OD could be trimmed off with a razor blade.

Re: Early 63 PCV

Joe, Yes the NOS one was very old. I traded a small fortune of fuel injection parts to get it.
Maybe the new owner here (who is my pal) will step up to the plate and brag to you all that he has the part.

I think you got the short end of that deal. I just can't see that first design grommet/retainer being all that valuable.

[Thomas B.]

First, second and third pics are the early design type grommet I just removed from my ‘63. Third fourth and fifth pics are of the commonly available replacement. The top of the grommet does not fit flush with top of the engine block as the original did.
