ive got slight leaks around my oil pan and i dont feel like doing that job over again...so someone recommended to solve that problem use 10w-40.

well i did a search and ive been reading about the german 0w-30 oil and i'd like to use that since it is the "best for the LT1", but that sounds like the opposite end of the spectrum.

i currently use 5w-30, should i switch to 10w-40 or give the 0w-30 a try?

 

Have you tried to tighten the bolts a little? Also, Have you ever heard of "High Mileage" motor oil? We recommend it at work to anyone who has a minor oil leak or build up,and Ive seen people that usually come in a quart low,come in full after 2 or 3 oil changes.I would just try some 5w30 high mileage for a couple of your next oil changes.

 

no oil will stop a leak....you can think what you want but the fact is there is no magic

even if it did expand the gasket or something it wouldn't work on neoprene

 

well i know the bolts are tight, its a bad gasket i think. either that or not enough silicone around the corners. i was told high mileage oils were a scam. i'll give it a shot though.

 

You sure its coming from the pan? LT1s are not known for pan leaks, they
are known for front seal leaks, and intake manifold leaks. I would run my
hand along the back of the intake manifold to see if its wet. I posted up my
tips on oil leaks, retorquing the intake manifold stopped a "waterfall" leak on
my 95 Impala SS clone.

yes we sell high milage at work also , i dont see any differnce really then other oils . same cars still leaks no oil will cure a oil leak unless its burning oil inside the engine , so i heard , all the high miage oil just add a additve or chemicl that acutally breaks done the rubber oring seals and makes them swell up and bring life back into the 10 plus year old seals . but there is no reason to use this stuff unless persnal perfence. like a bandaid on a open head wound . you can prevent your seals form leaking simple by changing your oil every 3,000 miles or 3 months ,

 

If the gasket is bad, then no oil is going to magically cure the problem. If it is indeed the oil pan gasket leaking, or wherever else, you may just have to buckle down and get it fixed.

 

my grandfather told me all the old tricks....Add trans fluid to sweel up seals, put oatmeal in your radiator to stop a leak.....Use soup cans to space out your rod bearings....It might get you home but thats it i'm sure that was probly on model T's anyway

 

Oatmeal, dang i was told that black pepper was the super cure all radiator stopleak. Also a little bit of brakefluid for swelling up those pesky leaking gaskets. Is there a shade tree area on this site. It would be a good place to put all the things you should never do to your Computer controlled high output engine.
