Cool... so what do you make of the gunk built up ?... Is the root of the problem the unbaffled valve cover?

looking at this pic a little closer, it looks like if a baffle was there at one point. Notice the two "screw holes"..

Those bosses are in all valve covers. Some of the valve covers come with the baffles loose in the box, and you have to install them yourself.

As far as the wet exhaust port, I wonder if the valve guide is loose, or the stem seal is missing.

Do a quick compression test on that hole, and an easy one to get to. They should be real close if the rings are ok.

I'll have to get a compression kit since I dont have one.... What should "normal compression" be ? 150-160 range ?


Any ideas on how I can make my own baffles? I really dont wanna go back to stock valve covers. I really like the look of the elite series.

Did you unhook the PCV from back of the carb cuz I had the same carb as you and the rear port of the Q-jet is for the brake booster not pcv! On your carb there should be a little steel tube sticking out the front in the center of the carb near the bottom. Having the the PCV in the rear of your carb is just like sticking your PCV hose right at your intake port of your cylinder heads! No wonder it sucked your finger!

Normal compression is between 150 and 165 on a stock sbc.

As far as making a baffle, I never even thought about it.

I really like the looks of these valve covers.

Just to clarify. It does not matter if the PCV is at the front or back carb fitting. BOTH of them draw from UNDER the throttle blades directly from manifold vacuum.

I had to download it from my website. The picture is larger on there.

The original is on my hard drive in my broken down laptop.

I have the exact same valve covers and have had a similar issue.
Send an email to Edelbrock and ask them to send you a couple of baffles.
I did that offering to pay and they replied the same day stating they were in the mail to me already. Sure enough, 5 days later (I live in Canada) they were in my mailbox. No Charge. Tremendous customer service in my opinion.
Best of all my problem was solved.
Give it a go and good luck.

Will give them a call tomorrow morning and hopefully they will send me a pair...I obtained these valve covers and air cleaner on a trade. I never bothered asking for the baffles...

You do not have to remove all of the other plugs.
