Hey guys, I was running the car the other day and noticed the oil low and I started hearing a tapping noise while driving... Parked the car and changed the oil (10w30) this is what happens when the oil is fully warmed up. If I drive the car as soon as the coolant is warm, you don't hear anything. When warm... Check out the video. ...you don't hear it under boost of course.

 

Definitely a lifter.

 

Should I take them out and clean them?

 

ive had the same noise for almost 1.5 years. i replaces lifters, cleaned the rocker arms/holes and it never made a difference. hope u find that cause cause i havent been able too.

 

Cool. I'm looking at getting some topline lifters and replacing them soon. This started happening after a 272 cam install and 5000 mile oil (e85) shame on me!

 

thats what lifters i put in

 

Cool thanks.

 

Pop the valve cover off and put some tension on each rocker arm and see which one has some play in it, that will tell you which lifter may be collapsed. deffinatley not a bearing

 

ive got the same problem didnt do it when i first got the car ive only had it 8 months

 

Replaced lifters. No more tick!

 

Bleed the lifters properly.. I had a similar noise before I switched my hks 272s for s2s

 

What are the ambient air temps where you live? If the lifters were not properly bled when you did a cam change, then you have a ruptured lifter. I have live with a ruptured lifter for years. FWIW, I have found that running Mobil1 0W-40 motor oil eliminates the ticking sound on my motor though.

 

I replaced the lifters guys.... No more ticking sound for me.
