Collateral Damage- My 70 Chevelle site build

[Blown353]

When it comes to 68-72 Chevelle wipers typically only the stripper model / post / 300 deluxe cars had the non-recessed park wipers that parked up on the windshield when off, nearly everything else had the hideaway / recessed park wipers. I think I've seen less than 10 68-72 Chevelles in person with non-recessed wipers over the last 25 years or so.

The recessed park wipers also used a different driver's side wiper arm with double links and the transmission linkage inside the cowl is a bit different than a non-recessed park wiper car.

IMO a 68-72 Chevelle looks a bit goofy with non-recessed park wipers since they stick out above the hood line sitting up on the glass even when they're off. As far as I know there's no longer any updated / late model style aftermarket motor kits for Chevelles out there offering recessed park. That means you're stuck with using one of the large and rather ugly original or reproduction original style wiper motors if you want recessed park. DSE stopped offering their recessed park late model style motor for Chevelles many years ago (I heard it was for reliability reasons-- lots of failures, and now they can't even service or repair the recessed park kits they sold years ago so if you have one and it dies you're SOL.)

If you want to keep recessed park, you may be able to relocate a stock recessed park wiper motor over to the far left side of the cowl under the driver's side fender and build some extended linkage for it, but I'm not 100% sure it will work... never tried it myself.

If you keep the OEM recessed park motor but want intermittent / delay, if you search over on chevelles.com there's info how to make an adjustable delay circuit and switch that works with the OEM recessed park motor and doesn't try to park the wipers every time it does an intermittent pause... better than the off/low/high which is all you have to choose from with the factory switch.

As far as the valve cover breather, what I've done on another car for cleanliness was locate the bungs and hose connection at the rear of the valve covers to be closer to the catch can but welded internal baffles/tubes that extended to the center of the valve covers, that way they're picking up crankcase vapors from the center of the valve cover and not likely to get covered by oil under either hard braking or hard acceleration. However, that was on an SBC with shaft rockers and tall valve covers that had enough clearance for the long baffle. LS valve covers sit very low and close to the rockers and there probably wouldn't be enough room to do that. If you have a vertical baffle out of the fill cap with enough height to it, it will probably work OK and not push oil into the catch can at WOT.

I'd say try what you have now, but check the catch can after a couple of WOT pulls and see if it's pushing excessive oil. You don't want to fill the can up and have it drip down on the exhaust manifolds.

Mounting the catch can on the core support seems to solve many issues and it keeps the back of the engine bay cleaner. I personally like the mechanics of the AN fittings and hose to the core support, but it's subjective.

Great idea Todd. I got so enamored with the simple clean MightyMouse brake master bracket I ignored moving it forward. I know there won't be any room on the drivers side with my A2W intercooler.

non recessed wiper gang here. Add Malibu to your list.

I personally think the recessed window stainless looks like an oversized belt to hold a belly in. lol.

Im not sure if wiring is different to convert from non recessed to recessed, I believe the switch is different and the motor is definitely different.

It's been a while since I've had one apart so I could be wrong, but I believe the dash switch is different but the wiring is the same between the non-recessed park and recessed park setups. The dash switch doesn't do the parking though, that's handled by an internal parking switch and cam inside the wiper motor that parks the wipers when you shut them off. And yes, the motors are totally different between the two setups.

And you're correct, the cars with recessed park wipers have a taller stainless windshield trim piece that sits about even with the hood and fender line. If I was putting an aftermarket non-recessed park wiper motor kit on the car I would switch to the shorter stainless trim piece for the cars that didn't have recessed wipers, otherwise the wipers would probably jump up onto the taller stainless trim piece at the bottom of every stroke.

Can you post a pic for me? I haven't been able to find a good pic of the wiper arms down and the hood closed.

Jody, it’s somewhat difficult to find any pics of non-recessed wipers on a 70-72... Best thing to do is do a google image search for “1970 chevelle greenbrier” (the stripper model) and some of the pics that show up will show the nose and hoodline with the non-recessed wipers. Most are flat hood cars though, not cowl hood.


Here's a pic on the car:



Here’s a pic of non-recessed wipers on a 70 showing how high they sit when parked:



And here’s a pic of recessed wipers on a 70. Note how much lower they sit:

Fit the Ididit column in today, fit perfect and the powdercoating is very nice. Could not be happier. And to make Todd happy I swapped the valve covers back to normal and mounted the catch can to the passenger side of the radiator support. Looks okay, liked it on the other side better visually but this should function better.

Thanks Troy.

There's only one opinion that matters. The breather will mist some moisture and I can see that being a cosmetic problem near the master cylinder over time. You could put a line and petcock out the bottom of the breather and have the ability to drain the water into a pan from time to time. This is a time where I pick function over form. I love for things to work as desired under max effort.
