Default Oil pan leak

I'm not driving my vette as much as I used to so when I last took it out, I noticed some oil on the garage floor. My mechanic checked it and told me there was a leak around the oil pan and the only way to replace the gasket was to pull the engine. Is that correct?

If it's the upper pan, yes.

Or try Titan Oil Stop-Leak. I had the same diagnosis with my 04 Murano. I Needed to pull the engine to fix the upper pan gasket. No Way. I either will put up with the leak or try something else. I researched and found the Product TITAN Oil Stop-Leak. I decided what the he**, and bought it. Not cheap. But it is still working after 12 months AND if it starts leaking again, you get a second free.

$120 for the high capacity version? Holy crap.

You do not have to pull the motor. I just did this job on 2 C5s. You can support the motor from above and drop the front suspension out. If you take your time this is a fairly easy job. Mine and my friends were leaking pretty bad and we had had enough.

That's another good option I suppose. The subframe would come out easily enough.

Interesting - I just looked and AllData also suggests to lower the front suspension. They say 5.9 hours.

Over a year, 15 months +. No leak, or no smell of burning oil on Headers. Very pleased with the result. But probably not so with many of the purist crowd on fixing things.

Hell, I'm all about a short cut if it works. How many miles in that 15 months?

It is my DD so about 4000 miles. Being retired, I do not drive as much as I did 10 years ago.

This is how mine was fixed. I needed to get an alignment afterwards though.

I have never been one for 'miracle cure in a bottle'. Not saying what was recommended is good or bad, just have never had one work for me, over promised and under delivered.
Kind of like putting a raw egg in your radiator to stop a small leak. Sure it hard boils and stops the leak temporarily and clogs up a lot of other small passages that you didn't want plugged.
Bite the bullet and fix it right.

If it's the lower pan try to re-torque the bolts

I agree. I had the same thoughts for the oil leak fix until I used the Titan product. There are some chemical products out there that do work. The other one I found worked for me was Reslone oil treatment that I used to quite noisy lifters in my Maxima.

No requirement to pull the engine to replace any of these gaskets. I think some stuff needs to be removed from the sides and front of the engine.
