I always check my
oil & my coolant. I had to put sealant in to get the leak to stop. I was very meticulous the last time I replaced the gaskets. I used the gaskets with the sealant ring on them this last time, mr gasket I believe. I researched the proper torq & sequence. I followed it to a "T". If someone has a fail proof method, I'm all ears. I don't proclaim to be an expert mechanic, but I have swapped out 1/2 doz intake manifolds w/o a problem until this one. I'm ready to pull the heads & have everything checked if it springs a leak. It's been holding for a good year or so now.
