Topic: 22r leak fix?

[tufluv82toy]

Any one have any luck solving the leaky front seal problem on a 22r? when I rebuilt my engine i put one of those sleve things on my lower pully and replaced the seal but it seems no matter what i do i still have a slow leak. It makes such a mess under my truck cause the oil hits the pully and flings it as a mist all the way under my truck as well as all over the front of the engine block. Will a new pully and factory toyota seal fix the problem or is this just a trait of the 22r series motors.... Thanks for your help

well if it still leaks with a new repair sleeve then i would put a new harmonic balancer on(lower pulley). on my truck though when i replaced the front pinion i just did the repair sleeve and it did wonders for me

repair sleeve fixed mine,   but you might try another pully

how did you put your repair sleeve on??

Check into this:

Toyota offers 2 front crank seals for the 22R motors...one that is like .25" thick and one that is double lipped and like .50" thick.  Also, your oil pump oring could be leaking.  If you need, I can get the part numbers for these seals at work on Monday...

Every sleeve repair will eventualy leak

This is due in part to the crankshaft end movement and the installition of the sleeve. Even after carefull installition of the sleeve, I still had .010" runout.

Get rid of the sleeve

Polish the hub with 400-600 grit sandpaper and install the seal in a differance location.
This can be done one of two ways.
 
1. Using a belt sander, I grind off the leading edge of the seal so that when it is installed, it will bottom out and sit deeper in the housing. The seal will contact the hub in a deeper, unused location.
2. Using the seal as a template, I carefully cut a circle out of thick gasket material and install it in the bore so that when the seal is installed, it will sit further out on the hub.

And in closing, never replace the seal on the engine. Always remove the oil pump, replace the housing o ring, and install the seal using a flat metal disk. Never hammer directly on the seal
Always use sealent on the threads of the top oil pump bolt. It goes thur the timing cover and can also seep oil.

my bros was leaking and we just fixed it and it was actually the pully that was worn cause it was hitting the edge of the oil pump luckly we had a spare pully

Thanks guys for all your help. What seal part # from toyota should i use? Im going to try marlins idea of shaving down the seal so it rides on a new area on the pully. Also what is the oil pump o-ring part #? Thanks again....TTL

just run up to napa and get the oil pump seal kit it includes the o-ring, crankshaft pully seal and the oil pick up tube gasket but you don't have to drplace that
