Leak down test

[Sebas]

I was having problems with my dipstick pulling out. About a month ago I did a compression test I has 141ish in five cylinders and 135 in the other That's not too bad. But, I just finished doing a leak down test with a harborfrieght tester. And they were 25-40% how bad is that ???? I can't find any info. Any help ?
Big car runs great other than having the dipstick pullout What should I do next??

25% is acceptable - 40% is suspect....HOWEVER make sure that when you bring the piston to TDC that you stop on the upstroke or the rings may not seal & you'll get a false high percentage reading. A long phillips head screwdriver makes a good indicator if you place it in the sparkplug hole. You can monitor piston movement & stop when you see it slow.

And make sure your PCV system is not restricted as that will increase crankcase pressure, too. (or your DS may just be loose?)

That's great to know Just to doublecheck I'm going to try it again. The only problem is I won't be able to warm up the engine. Would that be a problem ?? Which I also didn't let it get to full temperature the first time I did it

when i had my leakdown test done, the worst cylinder was 14%. am i to understand that, that's acceptable? i'm getting blue smoke on decel. when i added a catchcan inline with the stock system, the dipstick popped up.
