I didn't want to create a new thread but I tried using the search with no luck (did I ever mention how I HATE how the search functions here? lol)...

I'm getting ready to put my valley pan gasket, intake and valve covers back on my motor and couldn't find the thread where it was discussed about using the paper gaskets or not? I remember most said NOT to use them, but what did you use as a gasket instead - and did you just use any type of gasket around the intake ports or just the metal valley pan?

Thanks!

Just the pan, no gaskets, copper rtv in the 4 corners

I always used orange or red RTV on valley pan. If you leave it dry or use the stuff that comes with it, they will leak.

Searching for valley in the post subjects in the Q&A forum, with 2 year limit should yield lots of posts.

My 2c, is if you can fit paper in there and the paper is sealed correctly to the pan, it can only help. It does not take much effort to smear some hylomar around the ports, with or without paper, to create a better seal unless you are certain the surfaces are perfect.

Depends on the intake !!!!

Read my posts starting on page 2 of this thread

Same issues with my 71 Superbee

End of last summer i switched to a Synthetic oil and a Holley Street Dominator intake on my numbers matching 383 - Started going through oil like crazy - This spring i switched back to a convential oil like i have been using for the last ten years since the engine was gone through -Car never has burned a drop of oil since rebuild before

Anyways i discovered something when pulling the plugs and doing a compression test - All cylinders on the passenger side spark plugs had carbon buildup - Drivers side plugs were perfect and clean - Well light tan in color and looked great
All eight cylinders had compression of 135 - 150 #s

Anyways i have never used a paper gasket on the valley tin pans that i have installed for the last twenty years on big block mopars

The car idles and runs perfect - 750 rpms at idle with a Edelbrock 800 cfm carb and that used Holley Street Dominator intake - Engine .030 over / Mopar 284/484 cam and 906 heads gone through ten years ago

Was cruising to a car show this past weekend and the only time oil was noticed out the exhaust from my buds behind me was when letting off the throttle - PASSENGER SIDE EXHAUST PIPE ONLY

Time to pull the intake ??? Or head ??? Or both

Try some paper gaskets on the tin valley pan ???
Could it pull oil from the bottom of the tin pan to one head only ??? The intake bolted up fine with no vacuum leaks - Idles and runs perfect

Anyways i am scratching my head , no pun intended

Figured i would bring up this old thread that i found instead of starting a new one

Scott







Found the intake bolts to bee on the loose side last week

After a good retorque , took it for a nice long haul - No good , still used a little oil

This past Friday pulled the carb off - Oil in the bottom of the intake - Pulled the intake off and was plain as day
Could see oil around the intake ports - I had ordered the Fel Pro Intake Gaskets just incase , for the valley pan so i was good to go - Cleaned everything up and installed the fiber gaskets (Four) to the valley pan using Permatex copper sealant/spray

Retorqued the Street Dominator Intake to 25 ft# and everything looked good - Went to a car show today in Two Rivers WI , about 150 miles roundtrip

Came home and pulled the dipstick after the engine was cold - Not a drop of oil - PERFECT PERFECT PERFECT

Something so simple but yet so stupid for me not thinking about it earlier - I was thinking synthetic oil or a head - Rings

First time i have had an issue with just using the tin valley pan on a Big Block Mopar - Valuable lesson learned i guess - Some intakes require those fiber gaskets

Thanks for this, Scott. My intake is a Edelbrock RPM Performer. I find that strange that the intake would make a difference, but you never know!

I'll keep digging for that thread but I remember people saying the paper will burn up and are basically useless - seemed like general consensus was to use RTV only - but I wanted to be certain.

I never used the paper gaskets because I heard too many stories about the hassles to get the bolts to line up.
So I use just the valley pan and for sealing, (probably overkill, but I don't want to hunt down vacuum leaks) I use Permatex Hylomar. It's a blue colored goo that's sticky like honey. It's impervious to oil and gasoline and will never dry out.
I spread a thin amount with my finger around each port opening on both sides of the valley pan.
(The sticky Hylomar also helps to keep it from shifting around when I drop on the intake manifold.)
Before I set on the intake manifold I apply some Right Stuff to the corners and to the front and back edges where the hold-down bars go.
Never had a problem doing it this way.

I also used hylomar, seems to be good stuff. For anyone looking for some at a reasonable price ($11/oz was what I paid for my little tube), harbor freight sells UK imported (real deal) hylomar in 1.5 oz (I think..) tubes for $5.

I also use it as a sealant for the rubber gasket on the fuel guage sending unit.

I pulled these from the threads




Ya know with all the different combos and machine work they may or not may not work. On one of my 440s the paper gasket never fit right and did not need them but on another 440 that showed oil being sucked into the intake I put the paper between the head and gasket and it worked.








If you do not need the papers, fine, don't use them. Fel-Pro developed them at Chryslers request when they kept having warranty problems on the aluminum intake, six pack cars. The steel valley gasket IS designed for a crush fit, but aluminum intakes did not reliably crush the gasket like a hard, heavy cast iron intake will. Throw in the typical loose parts tolerences then and you can see why this problem occurred. Not all of them leaked, but enough did to cause repeat warranty work and this was the crutch that was developed. There is usually a good reason why a manufacturer makes a product, most people just can't be bothered to find out why.
