Form a gasket fail

[clinebarger]

Japanese automakers generally call for RTV on stamped steel lower sumps.

The Europeans somehow love anaerobic sealants as well. Hylomar is a polyurethane compound. Anaerobics want perfectly true surfaces to work well.

I’ve used Loctite 518 to seal a Subaru oil pump instead of RTV(Fujibond is called for, Gray Japanese silicone sealant). That way in case any sealant enters the oil path, the risk of a plugged oil gallery or passage is greatly reduced.

Most Nissan service manuals I've dealt with (older VG/VQ cars
Think Villager/Quest, and the good era of Maxima's and Pathfinders

The service manuals always had a Nissan part number that'd cross to Permatex Ultra Grey

Pull up the factory service manual, and review the instructions, maybe you've missed something or got a bad piece of info (torque spec?)

EM.pdf is the Engine Mechanical book, you could reseal the whole block if you wanted to

On the off chance you've distorted the pan or damaged the flange, a replacement is about $50

Dorman 264-513, tube of Ultra Grey

Give it another try, but let it dry longer and break out the torque wrench

Thanks. Unfortunately I cant use a torque wrench. Half the bolts are behind the front crossmember with clearance onlyfor a small ratcheting wrench.

I was worried what this looked like. Close to rotted through.

& some of that spray paint/primer stuff that catalyzes rust into whatever.........good2go.

That looks like the gasket for the V6, which is different. It is not the same shape as oil pans listed for your I4 Altima.

The item I linked to earlier in the thread is the same shape as your 2.5L oil pan. Be careful

EBay configurator says it fits but the one for sale right next to it says it doesn't and it's the same picture. If it's not the one well it's $13 lost. And I do have a 2003 Maxima with numerous leaks it'll probably fit that.

Personally RTV is my least favorite product and I avoid it as often as I can (there a few places where there is no alternative but very few). If the gasket fits this is what I would use with a coating of high tack on both sides. I cant remember ever having a properly installed gasket leak.
Look at split case engines that RTV was OE, leaks are very common after a few years. JM2C

So maybe its because I'm trying to do this after the engine has oil in it. Unlike the manufacturer who put the pan on dry. No way it's going to be pristine longer than a few seconds. The oil is going to drip down for hours and hours

Yes it will. If you don’t have time for it to drain then it’s not a great use of the product.

I’ve let it drain as long as possible with paper towels shoved up inside wherever needed. Then after prepping the pan for installation I pull out the towels and immediately install the pan. This gives you a few more seconds before oil has a chance to run down and across the mating surfaces.

Sealants such as Great Stuff and Honda Ultra Flange II can then tolerate oil contact immediately after the parts are assembled.

Will drain the oil today and try again tomorrow. Tape the ignition keyhole so I don't have a senior moment. I had purchased this for the second attempt. I purchased this a while ago . Go searching for the gray instead?

My favourite to use is Ford Grey, motorcraft TA-29 IIRC, which I believe is the same as an International product. It was used to seal oil pan sensor leaks on the side of the 7.3L diesel and is the best RTV I've ever used.

I’ve never used the gray the black has worked fine for me. I had never even seen the gray until a few months ago.

 

[JeffKeryk]

Grey is you best bet. Good luck.

 

[AutoMechanic]

I looked at the Gray today at Napa the guy told me that his customers like it better than the black I’ve never used it so I don’t know.

New oil pan is $16. https://www.ebay.com/itm/For-Altima...867131?hash=item3b2b05be3b:g:Ii0AAOSw7aNcmDGX

use genuine Toyota FPIG (formend in place gasket) - expensive but when was the last time you saw a leaky Totota?

Years ago had a Toyota with an leaking timing chain cover from the factory . They resealed it with the Toyota black F.I.P.G. sealer under warranty . Never a leak after that . The sealant from assembly line was white .

If it squeezes out like that, you're laying it on too thick. 2-3 mm bead max is all you need.

Yep, this - although I’ve had plenty of success with just the permatex black.

I always check to see if a lubelocker gasket is available first- then FIPG/permatex black.

I have my trans pan coming up and I’m debating rtv black or one of the available aftermarket gaskets.

They make RTV for the ATF pans I’ve read it is better than the black for those.

I'd go with the Lubelocker gasket. That's what I used on my Liberty instead of the RTV the factory installed the pan with. No leaks, nice and easy install, and no down time waiting for anything to dry.

I checked and lubelocker doesn’t offer one for my tacoma. I’m talking about the Fram/wiz/etc aftermarket gaskets

I’ve used the lube locker on ford Rear diffs and a few other things though.

Thanks, I would probably end up with the Toyota FIPG if I went that route.
