ezzzzzzz Posted March 21, 2011 Share Posted March 21, 2011 These are basically strips of 1/8" thick steel with holes drilled to match the holes in the oil pan. 11123-N3300 has a bit of sheet metal that folds up to protect the gasket from the exhaust down tube. Someone here will certainly have these bits laying around. I may even have them but would have to dig deep in parts bins. I'll try to get photos of my engine on the stand with these installed. The bigger problem is the lip of the oil pan being distorted from over-torquing the retaining bolts. You need to use a small hammer and flat dolly to smooth and flatten the lip at the holes to match the surface between those holes. Some decent sealant and a stock gasket will seal it right up. I usually use Permatex Ultra Gray but have also used Permatex 'aviation' sealant (#33 I think) or 'Right Stuff' sealant with great success. The secret is not overtightening the hardware. It may just be me but I never use the blue, orange or red silicone as it always seems to do a poor job by comparison. Quote Link to comment Share on other sites More sharing options...
jellobob Posted March 21, 2011 Share Posted March 21, 2011 (edited) If you are having problems sealing the oil pan Nissan makes a composite Competition Oil pan gasket (motorsport sells it ) It is far superior to the cork gasket but by all means use the reinforcement strips they even out the clamping force of the bolts on the pan . Also check that the pan has not been over tightened and that the bolt holes are flat not cone shaped or pointed toward the block . A tap on each with a ball peen hammer is usually all that is needed to level them .If you need the reinforcing strips i have a spare set they would be $10 plus shipping from 07055 Edited March 21, 2011 by jellobob Quote Link to comment Share on other sites More sharing options...
