Sup guys/gals my girlfriend's car is having some issues and having trouble figuring them out and was hoping you guys can help...

So far we've got 2 problems that are occurring, we've so far blown 2 oil caps into 100 pieces, it mainly happens when the car is rev'ed while stopped...at first thought maybe it over heated(which created crank case pressure) because the ECT sensor was bad but we replaced it and it hasn't over heated at all yet(but code wasn't eliminated assuming cause drive cycle needed to happen)...so next step could be the pvc valve is clogged? Just looking for any other ideas..


Next problem is when she takes off in 1st and 2nd it makes like a constant popping sound (kinda like a axle or like the axle is hitting something as it's getting into high rpms)...not sure what it could be so far have replaced both axles...again just looking for any other ideas that you guys might have.

Thanks in advance.

 

probably pcv fpr first one


check the bushinging for the lca and all the other steering components like ball joints and sway bar links for any looseness but sound like it might be bushings

 

Alright will look into those things thanks!
