I'm in the process checking the stock D-jet system for leaks to solve an uneven idle problem. Well from the looks of it I'm not the first owner/mechanic to deal with this issue on the car as every gasket I've come across is slathered on both sides with some kind of orange gasket sealer.
My question is should I be reapplying this gasket sealer with the new gaskets I'm using? Thanks, John |

Make sure you clean ALL the old sealer off or it will never fully seal.

Using the orange silicone is not recommended.
The vacuum hoses are 1mm undersize of their nipple and will shrink/conform to the nipple to be airtight, to the point they are hard to get off. Unless they are old or have been loosened many times, when they become not airtight and then need to be replaced. I have used a thin film of sealant on the interface of old hoses to their nipples in a pinch, but old hoses really need to be replaced for them to function as they were designed. I have also experienced leaks at the intake runners to head interface and use the spray on copper gasket on both surfaces, it works well and gets them airtight first time and permanently. Bontempi does this too...who I give credit to for the idea. |
