Changing the 2F Side Cover - but what else? (1 Viewer)

[WSOPgold2012]

Grommet part number for 2F is indeed 90480-18180 and PCV Valve is 12204-61010

When I replaced the grommet, it disintegrated in my hands - the rubber was toast, brittle and frail

And yes, I did remove the Tee. Not sure why it was installed in the first place - maybe faulty PCV value in the past.

Picture of the parts & numbers I used below:

Side cover reinstalled.

Took the time to thoroughly degrease (holy cow, what a ton of gunk, it was leaking for years)

The old cork gasket was a mess. Brittle and hard, like the cartiledge in my knees!

Not very much of a sealant.

Makes me wonder what the service life and service interval is on these.

Primed and painted w high heat satin black.

Now one of the nicest parts of the motor, except of course for my 135 smooth hrsprs and 210 ft lbs of juicy torque.

Thanks to all for your help!

Get rid of that T-fitting above the PCV valve. Oh and the grommet is 90480-18180. The PCV is 12204- 61010.

Why get rid of it? What’s the benefit?

What purpose did it serve? What was attached to the “T”?

What purpose did it serve? What was attached to the “T”?

Hose attaches from Tee to underside of air cleaner- supposed to mix cooler air back to carb or something

Is there an example of this plumbing in a diagram?

Thanks OSS, that explains it. Mine is a 79 and the HAI is set up like this.

Removed side panel fairly easily but found some brown crud had collected in one of these (collection area)? Yuck. Now to paint and apply copper permatex spray on cork gasket. New hardware too.

the milkshake stuff sure looks like water has mixed with the oil.
the lifter/pushrod to the right in your pic, the oil doesn't look like oil

have you drained the pan? what did it look like?

That emulsified oil / water is caused by blow-by condensing in the baffle of the sidecover or internals of the PCV valve. I have that on my motor in the winter. Just not so much. Rings might need replacing. I've considered placing some exhaust insulation over the PCV so it isn't so cold.

Ditching the po's T on the line going to the intake might purge more water vapor from this area on the engine.

If the engine is run at highway speeds for an hour occasionally, any water that gets in the oil will boil off.
