My main front and and rear seals in my engine are leaking the rear more than the front, a lot more. I used this stuff called no leak. I was wondering if anyone has ever used this product and do you think if would actually cure my oil leaks.

 

i used it with my last rig works good for a while but eventually wears off

 

I have heard it works so well that it blocks the oil from getting through any oil passages completely.

 

i was happy with it until it wore off

 

yea but then it says to just use more

 

Get it fixed. That's the only way to stop it. It'll avoid a bigger problem down the road. I have the same problem, my rear main seal is leaking, but luckily it's leaking very slowly.

 

yea but im throwing in another engine i just dont want to keep spending $ on oil

 

Oh ok. Didn't know you were swapping engines out. My apologies.

 

Snazzy marketing plan.

 

lol yea i know seriously but it says if it doesnt work you get your money back, and its all good

 

how bad of leak are we talking ?

 

well a qt. every 4,oook maybe a tad bit more

 

I wouldn't worry about that small of a leak.

It doesn't need to full. As long as its in the cross hatched area your ok. Just check it often.

 

Change your oil every 3K? That's what I do for more than one reason.

 

well i would still use the no leak its ok but yeah make sure to check your oil maybey veryweekend until you get your new motor

 

Before you go changing the seals.. check for excess crank case pressure.

With the engine idling take off the oil cap and feel for positive pressure pushing on your hand.

Then clean (or replace) the PCV. Then repeat the pressure test.

If the difference is not obvious put a pressure guage on it and find out what the spec is.


In my experience.. both seals leaking is almost always from excessive crankcase pressure.

If it leaks that slowly, Auto Rx may do the trick

 

The pcv point is something to check out. Its a regular maintenance item anyway and only a few bucks.

If it doesn't rattle when you shake it, its junk.

 

so your basically saying replace the pcv

 

yes after you check it. you can clean them if it dont raddle.

 

Its a potential problem. It goes bad over time. its not going to hurt to replace the cheap part.

It may not be the answer though, it does help with emissions.

 

well the pcv wasnt the problem and the no leak really made the leak ALMOST not leak lol its slowed down about 80% or 90%

 

could i use another bottle to try to fix it without damaging anything?
