MarkN Posted December 22, 2021 Share Posted December 22, 2021 OK, I searched the archives with no success, so.... Who has replaced the nefarious intake manifold gasket to seal an oil leak running down the side of the engine and onto the ground? Comments, suggestions, words of warning, results, etc?

rogold Posted December 22, 2021 Share Posted December 22, 2021 My Felpro intake gasket set came with the valley gaskets too (along with EGR gaskets, injector orings, etc). Instructions stated to put a dab of silicone RTV at each corner where the valley seal and intake gasket seal meet to prevent leaks. My engine was also seeping at the valley seals, so my recent intake gasket job will hopefully fix that too. 1 Link to comment Share on other sites More sharing options...
Philbo Posted December 22, 2021 Share Posted December 22, 2021 Which year is yours? The '91 is slightly different than the other years. It's not too bad of a job as intake gaskets go. Just make sure you clean the gasket surfaces real good. I suggest using a straight edge razor blade to carefully scrape old gasket naterial off. I like using Permatex right stuff instead of regular RTV, and I put a thin layer around the coolant ports because i had a decent bit of pitting from corrosion. Also felpro kit is what I would recommend. 1 Link to comment Share on other sites More sharing options...
