jdmfairladyz · Jun 17, 2014

The car is most likely dying because you have a boost/vacuum leak. You do have the BOV recirculated right? BLT the car again and fix all of the leaks, be sure to check around the injectors, throttle body, and intake manifold gasket. The ticking noise is most likely unrelated and probably caused by a collapsed/bad lifter.

Sounds like your having a rough time. The ticking sounds like lifter tick. If that's the issue, an oil change with thicker oil should fix it.
As for the leak, can you hear it? Is the car cutting out?

I have an aftermarket cold air intake and a aftermarket BOV and I use Mobil 1 full synthetic 5W-30 Should I just put some high milage 10W-30 would that fix it

There should be no reason to run 5w-30 in these cars unless you're in the Arctic circle.
Its summer and you're in a suburb of Chicago switch to 10W40 or 20W50. 10W-30 will be fine, but like I said.. its WAY too warm for 5w-30.

No. You need to do a test and replace whats leaking.

I run 10w-40 and it got rid of my tick. Like edged suggested you need to pressurize the system and listen for the leak. It sounds like a bigger leak so you should be able to hear it. If not, then start the car and start spraying carb cleaner around the vacuum hoses, if your hose is leaking it will suck in the cleaner and rev higher.

Oil preferences should be based on engine clearances when assembled. Not temperature of his location. If its an old motor and things are starting to wear down, thicker oil will be healthy.

This, google a boost leak test so you can make/buy a tester and found where your vacuum noise is coming from.

That would be great, but one assumes he hasn't built his motor, so his bearing clearances and oil mods are not applicable because they are stock. IF ANYTHING they're old and the clearances are wider... meaning he shouldn't be running anything under 10W-30 anyway. Even on a fresh stock motor 5W-30 is too thin. PERIOD.

freshly built motor i run rotella 15w40 even in the winter. these motors love the thicker oil, now that its summer im thinking some 20w50

edit: i would also think about checking the crank to be sure its in spec because usually a lifter tick goes away as the motor increases in rpm's

Oh no... Please discontinue the use of Mobile 1 as it has been know to cause problems in our engines. :notgood:
