Car : 2003 Honda Civic EX VTEC

After replacing the oil pan, oil pan gasket and using a 1 hour cure time RTV where the casting meets on four sides and some in the four corners of the curved part I have a leak catty-corner where the casting lines are. That is driver side front of the car and passenger side towards the rear of the car on the pan.

I torqued the bolts to 10 Nm in three passes 6N*m, 8 N*m and 10 N*m. I used the tighten from inside to out pattern.

What I suspect. The RTV was not enough? My torque wrench is not correct. This is not a problem since I have multiple. My oil pan is not true or the bottom of the engine is very off.

I would like to know the part number for an OEM oil pan gasket. Should I use Hondabond instead? Should I place the silicone gasket on both sides of the rubber gasket?

 

I had the same issue.. if the motor is in the car still it can be a real pain in the a$$... it's very difficult to get a true seal from this position (i was never able to even using an OE gasket)... only advice I can give to to take your sweet time and have someone help you so they can hold the pan while you line it up an tighten it down... you could try a super thin bead of rtv all the way around along with the gasket, do your first step of torquing, let it cure maybe 10-15 mins, go second step of torque, let it cure again for 10-15 min, and go with the last torque step... this gasket can truly be thorn in the side, best of luck

 

haitian82, thanks for the reply.After calling the dealership searching for this gasket. They said the EX model has no gasket. This make sense why I could not find an OEM gasket online only various aftermarket gaskets. The person I spoke to said they use Hondabond on the oil pan. Thanks for the helping everyone.
