I am planning on fixing the leak on my lower balance shaft tomorrow. I have all of the parts, and was figuring on going to the local auto parts store today to pick up a tube of Loctite 574, the recommended sealant when resealing the cover. They do not carry it. Are there any other sealants that can be used? They have the Permatex high-temp red RTV silicone gasket maker. Would this work, or should I put the project off until I can find 574?

I would wait until you can find 574.

You can order it through McMaster Carr. They have a warehouse in NJ and it should arrive tomorrow if you order by 3 or 4pm EST if shipping to you in PA. Also may want to check if you have a NAPA by you, i think they carry 574 also.

Thank you, I think I will wait until I can find 574.

The 574 is the recommended sealant but I've used "Permatex Anaerobic Gasket Maker" on a couple of engine rebuilds, in place of the 574, without any problems.

What also works well is the sealant they sell at porsche. I ordered two tubes of the stuff to seal the engine case ( no gasket, scary stuff ) and then used it for the rest of the engine. No leaks. I plan to use it on the 951 as well. It is about $53 per tube, one should be enough.

I found the 574, and started the project yesterday. Have the rear belt cover off, power steering bracket, and working on the headers. It is a lot of work.

Wait what exactly are you fixing? Is there a link that explains this. Just curious maybe i would need to do this.

the rear of my lower balance shaft housing is leaking. It is coming from the end cap at the rear of the cover where the inner o-ring is located. from my understanding the o-ring shrinks and gets hard from it close location to the exhaust manifold, and just age. It is not an easy job.

That's exactly what happens the o ring shrinks causing an oil leak, a temp fix if you have to drive is clean the area real well and coat the out side in the recessed area with high temp sil. this is only temporary . ( this is just if you have to drive her )
