had to chime in here...
Prob a stupid question, but could this also be the case for a 2.3-16???? I've got that same 'rakka rakka' noise that goes away immediately.
Is the check valve inside the filter housing or inside the oil pan (reading this post sort of describes both)?
Sorry for the ignorance, I'm just trying to abolish that confounded sound as well here!!! Any insight appreciated! Thanks.
