Depending on where I look, I'm seeing yes and no. I'm probably not going to unless some of you feel it is absolutely mandatory.

Thanks.

 

yes, you need to use sealent. If you don't you wont have a tight seal and will lose oil. also not to mention a water tight seal. it only cost $5.00 more and is the right way to do it, so why not do it.

 

No, you do not use sealant on the rubber gasket. It will cause the gasket to slip when you torque the oil pan bolts. The old gasket will have two small dabs of sealant on the corners of the gasket. Apply sealant to same areas that Honda did when the engine was new.

 

Yes you do need sealant. This is coming from some one that use to work at a Honda dealer. Use a thin coat of Honda Bond all the way around the gasket on the block mounting suface and the pan itself. Make sure you don't over tighten the bolt and smash the gasket, then it will start to leak. Make sure youput it right down the middle where the bolts go through.

 

i used sealant at first time and gasket slipped out of its place and oil leaked. I then checked with a honda mechanic whether if i should use sealant. he said no sealant but a tab where timing/oil cover on side meet and where the concave is on other side - just tabs and make sure that the meeting mates on both oil pan and engine block are 100% free of oil and clean. i did that and it worked. but had to do it twice so do not use sealant from my expeirence and what the mechanic said. also make sure to tighten nuts equally all around little by little until all are tight enough.
