Dressing up the buick engine, removing air pump. but the Thermac?

Hello. Im removing the air pump and noticed the thermac line went in where the air pump junk went to. Is it needed? Under the EGR is the pump line Im going to remove, but when I removed the thermac on the caprice it ran rough. anyone else removed the thermac?

one more thing. On the caprice I painted the engine chevy red and wanted to know some nice Buick engine colors, just not black.

A photo I found on the 3rd gen site. [You must be registered and logged in to see this link.]

I believe mine is capped off there. I'll snap a pic of my engine bay for you now.

If you do not cap it off, you will get the symptoms of a vacuum leak. (it is a vacuum leak) I beleive the line is part of the vacuum manifold and may operate a couple of other things as well. Just capping it off, may cause some other issues as well. If I remember correctly mine is not capped off, but I do have a cap on the "T" where the vacuum manifold goes (went) to the Air Injection control valve.

I'll go snap a pic of mine right now, Dad and I replaced a bunch of the vacuum lines when I cleaned the EGR passages, since many of them broke (damn brittle lines..)

Do you not need the air pump to pass emissions inspection in NYC?
Also, don't you need the Thermac hooked up for proper cold engine warm up?

Okay, mine isn't capped off there.

The color you see most often in later models is the Buick Late Red engine color and is most identified with them IMO.

Nice red. almost orange.

I pass my own car lol.

I have to recheck the thermac line, I know it gos by the egr and is connected to the air line. Double check everything, ill snap a pic of what im doing.

Here's the color used from the early '50's to the mid '60s on the Nailheads.

The fitting "Thermac" goes to the diverter valve for the heater, if you have it. It has a one way valve in it, to keep vacuum in the line at low vacuum throttle settings.

That turquoisey color was the one on I was thinkin'. Add a pair of finned and polished aluminum valve covers and you got a hot rod look!

OK!

Oh good lowered - that baby is HOT!

Excellent work. Love those.

Gotta add those cool spark plug side covers that were on the 322!

I got to go with that green. waiting for the rain to stop so I can get started.

Always liked the nailheads and that quirky head configuration.The turquoise engine with the chrome and finns would be my choice for a hotrod restorod.That gorgeous 455 would be my
choice if gas wasnt so damn high and unleaded.

Looking for cheep finned valve covers, but the hold up was I bought real spoke rims, size 14, but there painted white and the tires are size 60 high. bit of a lowrider look, but if I put 70 high with white walls might look better. 100 buck is a steal. maybe someone steal them lol. plus Im taking the paint off them and my buick caps fit for the center caps, Added pics in the tire section btw.

I was cleaning the motor for paint and trying to find the oil sending unit. my dash reads low oil. where is it? on top of the oil filter?

are they center bolt VALVE COVERS? if so i bought a pair for 50 bucks from autozone look up part#Spectre 5428 Engine Kit Small Block Chevy Center Bolt Chrome 1 Kit in amazon .com the tbi bolt was bent on mine but it worked for my 1992 350tbi
