Hello all,
This may seem like a dumb question but here goes nothing. There are tons of long forums regarding crankcase Pressure and the good ol' dipstick popping out issue.
I've gone through most of the threads and I understand a broken or damaged ringland can cause the dipstick issue, but what I don't understand is if it's normal on a high output built motor?
Essentially, the Evo 8 I'm looking at is on a precision 6466, built motor, and the owner has the dipstick spring installed. Car makes about 700hp on E85 and has the STM vented catch can with AN lines(the cylinder one by intake manifold not the box on trans).
Should I be concerned about the dipstick spring being present and being a bandaid for a deeper issue or is the spring a normal thing on a high output scenario?
Some forums mentioned the dipstick will pop out regardless of how good the crankcase venting is with high boost, is that accurate?
Just trying to learn about this convoluted topic as much as I can, as the sight of the spring and catch can seemingly filling quickly concerned me.
Thanks in advance.
