Car Forum / Toyota / Toyota Trucks / October 200422R oil pan gasket
Ok, I am going to give this another try to replace oil pan gasket on my '84 Toy PU 4x4 with 22R engine. First time I used a cork gasket from Autozone. Started to leak shortly afterwards. Second time used Permatex RTV. Seemed to work but started to leak after 4 to 6 weeks of use. This time I have an orginal Toyota gasket. I noticed Toyota's maintenance manual shows putting a small bead of RTV only on the front 2 corners of the gasket before installation. Not sure why only the front and not the entire gasket. HELP! What is the secret to installing the oil pan gasket on the 22R without having a leak? Any information is greatly appreciated!

I'd install a rubber gasket and put some Permatex sealant on it after cleaning the mating surfaces and torque to spec making sure you tighten the bolts in a criss-cross manner I had the pan on a flat surface and I couldn't see any warpage. Did you put permatex on both sides of the gasket or just one side? >> Ok, I am going to give this another try to replace oil pan gasket on >> my '84 Toy PU 4x4 with 22R engine.

With the toyota rubber oil pan gasket it's probably going to be hard to get it to sta in place while you spread it out in position. A little sealant along the gasket to make it act like glue to hold it in place wouldn't hurt. My manual says to torque the oil pan bolts to 9 ft/lbs. Cleaning the mating surfaces is important, Scotchbrite pads work well. > I had the pan on a flat surface and I couldn't see any warpage. > [quoted text clipped - 25 lines] >> put some Permatex sealant on it after cleaning the mating surfaces and >> torque to spec making sure you tighten the bolts in a criss-cross manner What I always do when I install a Toyota 22R pan gasket is paint both sides of the gasket with that Permatex brown sh.t -- i even paint a light coat on both mating surfaces. I lay the gasket in place and then I put the pan in place and tighten all the bolts to about 5 - 10 lb-ft of torque. I *DON'T* fill up the thing with oil for several hours or even overnight. I think this truly is the secret to not having a leak. (btw- I make sure both mating surfaces are scraped and cleaned completely before painting anything on there) > I looked up my 85 Toyota Truck Service Manual, says to put sealant at > the four corners, not two like your 84 manual does.
