Overfilled at oil change

[Harrai]

Hi all

I have a Jeep Wrangler TJ 4.0.

Recently the workshop overfilled the oil by approximately 1 litre. I drove home, approximately 30 miles before noticing, and immediately drained off some oil to the correct level.

I have since noticed a small oil leak from the front crankshaft seal. Is this likely to be excess oil from overfilling? Will is fix itself when the oil in that area of the crankshaft has leaked away? Or will I need to replace the crankshaft seal?

Thanks

Harrai

Thanks for your response. Might have been a bit more than one litre - 2 or 3 cm on the dipstick. There was no leak on the crankshaft before the oil change

If you've drained it off you should know how much came out.

I didn't measure it exactly.

What I'm trying to establish is if the leak at the crank is temporary due to overfilling, or if seal is likely to have blown.

Impossible to say with certainty.

Half litre overfill = not a problem

Ten litre overfill = definitely a problem

Though to define where the crossover point is.

Could be a total coincidence (or you hadn't noticed it previously)

Clean it up and monitor it now level is correct.

Don't waste any effort/thoughts/expense on thinking that the garage will fix the seal for free - not a chance IMHO!

Thanks for your response. I'll clean up and see how it goes.

I wasn't contemplating asking for a free fix - it's an old car, and things need repairing every so often
