Oil pan leak (Page 1/4)
hunter29 AUG 09, 01:31 PM
I searched and read, so I'll get to my question not knowing yet what the problem is.

86 Gt 15K miles, is running High Mileage oil worth a try if it's not the pan gasket ?

Thanks

Have you checked the distributor O-ring? Many Fiero owners have been fooled over the years thinking their oil pan was leaking... when oil was actually coming from the base of the distributor (it's a high oil pressure area) and running down the block.

You are the man Patrick , save me once again.

Yes it looks wet, so how difficult ? Got a link by chance please? Like the best link for this, otherwise I will find something..

Also since I have to pull the distributor should I replace it with a new one ?

If so Cardone I hear is good, does it have the new pickup ?

There is no point replacing the distributor unless there's something wrong with the one you have. It's not like changing out an alternator. The gear on your distributor will wear into the one on the cam... but technically, the cam and the distributor gear will take wear, and that'll result in increased clearance, which offsets your timing and other things. If your distributor works fine and your engine runs well, then just replace the O-ring.

Make sure you label your plugs when you take them off... or just remove the distributor cap and leave it connected to the plugs when you pull the distributor.

I agree with Todd... no point replacing the distributor unless you suspect something's wrong with it. While it's out, you could perhaps reduce the end play of the shaft by using shims at the gear end.

The most important thing to mention though, is do not replace the O-ring with a regular rubber one. It will get rock hard due to the heat, and leak. Get a high temperature O-ring from Rodney.

If you have any difficulties with the static timing, you can consult my write-up Here.

Very well, thanks so much guys !!!

One more thing guys, the pick up has some rust on it , if it's rust, been some time since I've seen it.

I'm wondering if that's normal, it didn't look so bad that I thought it should be replaced but I believe the distributor has to be removed to replace it.

So wondering if I should at least do that ?

Thoughts? Or don't fix whats not broken..

Can I lubricant the new O ring with silicone grease? Do I need to lubricant anything else?

Thanks
