97 Challenger 1800 Oil Tank Question

[Challenger1800-OKC]

Hello All! Another 'newbie' question - I'm needing to fix a small oil leak in the oil tank on my 97 Challenger 1800. I've already ordered the parts (its the grommet on the underside of the tank that's leaking). And I'm also going to change out the oil filters.

My question is this - Once I replace the gommet and filters, how to I 'pressure test' the oil system to ensure no leaks and no air in the lines? I'm told I need to do this to ensure no damage to the engine system. But, I don't know how to do this or what (if any) special equipment may need?

Thanks All!!

Dan I'd say you satisfactorily found the source of your tank leak after we talked, that grommet should have you fixed up and I wouldn't worry to much about introducing any pressure to the tank, those are obsolete tanks and the last time I saw one for sale used the stick up artist wanted $300.00 for it. (they are hard to come by) -something goes wrong regulating the air on a pressure test and that might not end well at a tank seam.

The one thing you want to be sure and double check is the small vent line with the one way check valve that mounts above the oil tank, that has to allow atmosphere back into the tank so the oil can flow. Make sure it's clean and working ok and get's mounted back when you take that all apart.

Just put a quart or so in the tank for starters when you fill it and let that ride for a day or two and inspect everything for leaks.

Great! Thanks Waterluvr! Will update you once the work is completed!

Once you get the oil filters changed make sure you bleed the system. On the oil pump is a bleed screw just about the center of the pump. Open it up a let the oil filter and oil line fill. (gravity)

Keep an oil absorbent rag under it so as to not make a mess.
