Intake manifold gasket leak

I was helping one of my friends out this past w/e with his scoot and located his problem a torn/worn out intake manifold gasket. My question can I use permatex ultra black silicone to make a new gasket? I can only find a stock oem gasket over seas and it will take 2 + weeks to arrive.

you didn't provide any info on what kind of scoot this is for or how many cylinders. Not sure I could help you regardless, as I've not had fabulous success trying to replace a true gasket with something out of a tube.

If you are going to try the silicone approach I would at least suggest you look for the copper stuff. I've used that on a cylinder head with some success.

Hope you can get it running, but intake leaks are dangerous so just know you are risking a lean condition that could do potential damage, unless it's critical that the scooter be ridden in the next two weeks.

its a mojito scooter (same one as i have)
the brand of scoot is meaningless...an intake leak is an intake leak.
the permatex copper is not made to come in contact with gasoline.

well there ya go. Only asked to determine if the manifold was rubber over sleeve style or metal to metal.

Since it's just a simple round gasket with holes for the bolts I would just get some gasket sheet stock from the auto part store and trace it/cut it before I'd try to use sealer. After all, 'an intake leak is an intake leak'.

If you are referring to the Piaggio 4-stroke LEADER engine . . what is so unique about the intake manifold gasket that you just can't fabricate one from the various gasket papers?

In this application, valve packing may be an alternative to the silicone products.

Use the copper silicone as dabears stated. In addition, buy some loctite clear sealant and apply it around the edge of the the intake manifold to have an airtight seal. This stuff isn't just for water leaks. I used both of these products on my 278cc scooter.

I actually used the copper silicone on a plastic gasket that was dripping some coolant. It works well. The water sealant reinforces the gasket and I used it keep my windshield from rattling due to two of the tabs I broke by yanking it. No more rattling.

One more thing is it worth going that route becasue often the OEM gasket is cheap , eg ch80 is 15 bucks . Also with most engines out there there are cheap clone gaskets kits. The cn250 clone kit is 20 bucks . The only issue with doing what your doing is using to much and having it end up in oil or water passages in the engine.
