 Post subject: Slant 6 Valve cover

I bought a new Offy valve cover for my slant.

A few Q's:

- there are no wiring loom clips on the valve cover, what is the best way to run the wiring to the coil, alternator, etc.?

- unlike the steel valve cover which has small cut-outs for the valve cover gasket, what is the practice for fitting the gasket to the Offy valve cover?

Thanks.

I glued my gasket to the cover, and used commercially available wire looms held by the cover bolts.

Check to make sure the flanges are not warped. Seem to recall some had problems with warped flanges.

Also, those covers have no provisions for crankcase ventilation -- just for an oil cap, which (even if it is the vented type) is not sufficient. See here and here for a few different ways of remedying that.

As for the valve cover gasket: ordinary sewing thread. Tie little loops of it through each cover-and-gasket bolt hole so the gasket is retained to the cover. Install the cover; the threads won't affect the seal and will almost disappear with it installed, but if you want them all the way gone, you can snip and remove them once each bolt is started.

Or, install threaded studs in the head, lay the gasket on them, install the cover, and finish the job with nice shiny chrome or stainless acorn nuts and washers.

And they don't have any provisions for baffles like and original valve cover. This is what I did to solve the baffle AND PCV issue:

There is a chemical near the RTV in most auto part stores that is used for adhering gaskets to surfaces. I forget what it is called but it comes in a tube, is red and is like a gel. I used it on my oil pain gasket to hold the long strips in place so I could get a bolt started.

I like the idea of using studs in the head and acorn nuts to align the gasket and attach the valve cover. Sweet!

Is anyone able to advise on the size and length of the stud/acorn nut? A picture of a valve cover with this setup would be good too, even for the stock valve cover.

Thanks

Gorilla snot (3m weatherstrip adhesive, comes in yellow or black) works well. Works like contact cement. Couple of dabs will do it. Sticks quick and won't let stuff slip like RTV.

I thought about trying studs before... I was worried about having to lift the valve cover up too high to get it on/off the head - the heater core hoses make it a bit difficult as it is without studs. Of course this will vary body to body.

and I run my wires hoses away from the valve cover so I can pop it off for valve adjustment.

Here is the PCV and catch can arrangement:

My offy is warped, but I'm using double thick silicone gaskets and it doesn't leak. I had an older one that wasn't warped, so perhaps they had a bad run, I also glued my gasket to the cover, reuse it, should last forever.
