Try to rip a cork one in half.
Then try to rip a good rubber one in half. I would use a good rubber gasket .

Best valve cover gaskets I have found are REAL GASKETS.MADE IN TENNESSEE. THEY SOLVED MY 390 FE VALVE COVER LEAKS.NO LEAKS SINCE 2007.

Re: What's better: cork or rubber valve cover gaskets...
First, you need a rocker cover that is flat on the bottom. Then, it must be clean. Sandpaper it clean, shiny metal clean. Test fit a cork gasket to make sure its right, then attach the cork with 3 M trim cement. Let if set, then spray the cork with WD 40. Let it sit, then spray it again until it is saturated. Install the rocker cover to a clean surface, and do not over tighten the fasteners. It will not leak, and it can be removed and replaced a number of times over several years.

Re: What's better: cork or rubber valve cover gaskets...
I have Dart heads on my Ford, bought a whole top end kit. Their gaskets are cork, but 2X thicker than regular ones.
I glued them to the valve covers with RTV and am using nothing on the head mating surface. I use spreader clamps and actually torqued the bolts. The rubber ones are okay too, those you can adhere to the covers. The biggest sin is over-torquing them and bending the thin covers. |

Young guys need to print out the last sentence from Bobss396 post, then staple it to the wall in sixteen places.

I have lost track on the number of valve covers I have fixed over the years after seeing that some gorilla had turned them into bananas!!!!

Re: What's better: cork or rubber valve cover gaskets...
Learned the hard way. I never torqued valve covers in my life until this build, looked it up and went by the numbers. So far so good.

Re: What's better: cork or rubber valve cover gaskets...
Someone told me ramshorns are h**l on the lower part of the valve cover gasket. Which material holds up better to the heat?

Yup! When I changed the leaking one yesterday; i held up a small metal ruler on the lip; had to "adjust" two high spots due to someone cranking down too hard. I used new lock washers and torqued 'em down to the factory shop manual specs....and NO tighter. |

Re: What's better: cork or rubber valve cover gaskets...
did you use a flat washer between the valve cover and the lock washer? doing so, will help to keep the valve cover from deforming.

Re: What's better: cork or rubber valve cover gaskets...
I have used rubber, cork/rubber and cork. The unimproved pure cork fel-pro gaskets work the best and have reused the present one 3 or 4 times. I just stagger tighten them from front to back and back to front and then do a final recheck the same way. I use a 1/4 drive ratchet and hold it at the head with just a little thumb pressure on handle near the head. Works great and since I'm not the sharpest tool in the shed I pray and I get some good answers on how to do stuff.
Edit: From my understanding the improved cork is the cork/rubber one--I used it and was not impressed. Sometimes old teck is the best teck. Last edited by greenpondmike; 09-10-2020 at 02:23 PM. |
