PCV grommet dilemma

[ErikinSC]

So... I ordered a replacement PCV valve grommet - and the 'new' OEM grommet looks like it might be TOO BIG. I have a '76 2F block and an F (maybe F.5 head - per the PO)

Cross referencing PN.

PN checks out.

Does this look like there is a section of grommet broke off inside of the vent tube?

Old grommet looks like it IS broken :

It's been forever since I replaced mine... That does look like part is still inside ...

I kinda recall it goes on tight and the Pcv goes on REALY tight

Erik, I purchased one from NAPA for couple of dollars and fits perfect. Your old grommet is still in there upon removal of old the new OEM grommet should work.

Are you replacing the pcv valve also or just the grommet? Everyone is telling me that the valve is NLA.

I just read your thread regarding hesitation upon acceleration, and now this one. Grommet does indeed look broken off, and yes, fitting it into crankcase breather, it is snugggg. The inner diameter where PCV goes appears similar... Try it and see

Your block SN appears to be around '86-87... with an earlier F head? Interesting. Given the history of a rebuild et cetera, I wonder if the head was decked too much / block top shaved, creating too much compression? And thus the heat issue messing with fuel/air mixture in Weber carb after running 20-30 minutes? You've been battling this, in the ring for seven rounds... and the bell sounds for round 8

Thanks..... I'm trying to get the other portion out now.

My PCV valve was available from Toyota, I ordered 2. I ordered the grommet AFTER I changed the valve and found the grommet had a crack part way..... Once I went to replace the grommet - I was fully split and that's when I saw the difference in size.

I got one I thought was too big at NAPA so I ordered OEM grommet and PCV valve and they were the same size. Like the others have said, it is tight but really does work.

 

[ErikinSC]

HA HA HA ! Gotcha !

Now, to get the new grommet in....

 

[ErikinSC]

Success!

I swapped mine out with a pcv valve and gourmet from cruiser corps. It was a pain in the back end getting out the old valve and then I had to be extra careful getting out the rubber bits that had rotted and crumbled. Always feels good to do the small Maintaince on these.
