leaking felpro gaskets ???

got an old 350 60's model , got a new oil pan took off the old 4 piece gasket and replaced with a new 1 piece and it leaked at the back of the motor, thought well i didnt seat it well or over tightened the bolts ,bought a new 1 piece felpro blue and that ******* leaks also, a friend told me that those gaskets were for vortec engines ...... need info guys... did i scew up the installation or what... thanks

 

You might have.... Try using Permatex(sp) instead of the end gaskets...

 

I've used those gaskets on many older engines. First thing is, follow the instructions exactly. If you use sealer other than just a dab where they tell you to, it WILL leak!

Also make sure you have the right gasket for that oil pan, as there are two sizes. Of course this will cause a m***ive leak at the timing cover.

Captain, I see the words " new oil pan ", in the post, and it sets off the ol' red flag. Try fitting the pan without any gaskets, check all around the perimeter very carefully, you just might need a little hammer/dolley work/ gentle persuasion to make it sit just right to seal up. If its rocking, check to see if the pick/up for the pump is not hitting the bottom of the new pan. Clean the metal surfaces with laquer thinner and air dry before you use any gasket adhesive, and even for a good seal for the gasket itself. Be careful NOT to overtighten. TR

 

duojet is right there are two different gaskets and just put a dab of rtv in the corners I use them all the time.

 

Are you trying to use a pan gasket for a "one piece rear main seal" motor on an early block? If so it will leak like a tea strainer. The entire back part of the block and pan are different.
If not then I don't know, because I haven't seen a one piece pan gasket for the two piece seal motors. Be aware that my *** is behind the times however.

 

NAPA sells a one piece gasket for pre 86 SBC dipstick on either side for $24 bucks OS34510T I've used several of these with good results

 

Just a extra note on new oilpan,if chrome? sanding chrome some were gasket goes helps ruff enough for seal to work better.

 

Running an older 350 in the woodie, one piece gasket with a Champion oil pan. No leaks so far, but it's only been on the road since this last spring and has run about 1500 miles.

 

I'll take an old stock oil pan any day of the week...it was made to actually fit the engine. I've only used the new gaskets 3 times, but they work like a champ with the stock old oil pan.

If your new oil pan was made in china you might as well just drive over it with a bulldozer and look around for an old one to replace it.

 

Thanks Jim, that pictures worth a 1000 words!!! Sad part is it will go back to China, and come back next year as a toaster, {A really cheap POS toaster}, TR

 

that was great !!!!!

 

love it, only used a dab of sillycone , pans origin ??? nice looking steel 6 qt. got at dragstrip swap meet, my old pan was home made back in the 80's and it was on my stock car and beat to hell leaked at the drain plug, i may just put it back. thanks everyone im changing these gaskets on my back, im begining to fell like a jack in the box

 

There were at least 2 different seal thicknesses, used over the years.

Using the wrong seal will guarantee leaks.

 

The different seal thickness was at the front of the engine, the depth of the groove in the timing cover changed around 1974, and you need a pan gasket that matches the timing cover you're using. Other than that they should be the same from the early engines up to 79 when they swapped sides with the dipstick tube.
