front case oil seals

[1Gina2G]

Is it possible to remove the front case oil seals without damaging them? What's the best tool to use? Specifically the ones for the crankshaft and oil pump sprocket.

How about the best way to push in the seals? I've got a brand new front case and I've changed the oil seals twice because it wants to leak once the engines warm and running. Not sure why this keeps happening with this oem front case..

So you want to pull the seals and re-use them? You will usually damage them every time you remove them. Just pick up some new ones. The crank could have a groove worn into it from an old hardened seal and that is why it keeps leaking.

the crank looked pretty smooth last time I redid everything, I looked and I oiled up the crank before installing the front case. used threadlocker on everybolt this time, all new gaskets and oil seals.

The seals are brand new so I was hoping to reuse them but I guess if they can't be removed without damaging, oh well.

I also filed down the oil pump sprocket a little since I know its mostly the problem. I read everyones threads and I've tried everything I think.

Elaborate on this please.

The seals aren't the only possible leak point. Are you sure it's the seals?
Why would you expect to fix the leak by taking the seals out and then reinstalling the same seal?

I would like to know why would you want to re install seals, because that should never be done if its leaking. if it was an easier area to access i can understand someone trying but on the front case? i wouldn't recommend that. Just use new seals.

PM me if you want a set of front case seals. I have a set that I have no use for it (you just pay shipping and they are yours).

The first time I had an oil leak from the timing side I checked all the oil seals for the front case and the one behind the oil pump sprocket had friction marks. So I assumed it was probably the problem.

There wasn't any oil dripping from the head or camshaft seals, it was clearly the frontcase. So I removed it and the oil pan, new gaskets for the front case and oil filter housing. Both the crankshaft and the oil pump sprocket rubber oil seals were replaced with new ones, lubricated in oil with the spring side of the seal facing into the engine. All bolts for the front case were threadlocked and torqued center out. RTV was used for the oil pan and everything had a week plus to dry so I don't understand how there's oil still leaking.

The oil seals were never re used thats why I was asking.

they are 10$ on rockauto.com and possibly cheaper with our dsmtuner discount code.

For $12 I got them from partsdinosaur and even came with the gaskets for the oil pump housing and front case and both seals.

I noticed you said the seals were leaking once the car was warmed up. Try this, add a little bit of grey rtv on the outside surface of the seals to make sure they fit snugly into their respective bores.I have noticed that some seals fit too loosely when installed without rtv and begin to leak as the engine gets hot and the metal parts such as the front case starts to expand.

Has anybody else ever done this before? I actually did think about this, but then I was sure it was a bad idea since the shaft in the midde moves. All I did was lubricate the rubber seals with motor oil, pushed em in, pressed all around it to make sure it was snug.

You don't need rtv on the outside of the seal, some people do it for extra insurance, but it isn't required. You are NOT supposed to put oil on the outside of the seal when you install it.

Funny, I'm going through this exact same thing with my ITM pump right now. Take a close look at the crank to seal contact area. Mine is not even all the way around and it actually ruins a seal every 500 miles or so. I'm contacting ITM about this as soon as I have a chance. I've had fitment issues with this pump since day 1.

This is a trouble area on these cars. The seals arent enough of a pressfit. Oem or otherwise. Usually I can put them in and out by hand no tools. so I always ultragreythem In

 

[mcneilmg]

I agree. While I was rebuilding my uncles 73 olds 350 in college last year, my instructor had me use a type of rtv for the front cover and it worked great.

Look at you crankshaft seal. It is probably has a gap on one side of the crankshaft and snug on the other. If it does, that's where your leak is coming from. You will have to get an alignment tool to line it up correctly
