4 cylinder oil pan gasket install? Help (Page 1/1) Wayne Renninger MAY 17, 07:56 PM 3rd time trying to get the gaskets to seal properly, doesn't seem like they line up properly between cork and rubber? Do you think I could replace thin rubber for heavier cork? Will the thinkness need to be doubled? What are some tricks to seal properly? Haven't had any success withRTV or jb Weld.Seems like the u shaped rubber at the flywheel isn't thick enough, width wise and it turned.What about height of said rubber? No problems at the three other sides, only at the flywheel. Any help ? Thanks edfiero MAY 19, 10:38 AM On my 84, I've always used RTV on the oil pan and valve cover. Its never been an issue for me in 35+ plus years
