60 degree v6 lifters=loud lifter tap

They do, if you have a 91-93 GTP.

You'd think with a GTP package they'd include a freaking oil pressure gauge.

I am running 5W-40 Castrol Syntec and I am still getting some noise. Can't really hear it when you are driving though at higher speeds around 40 and above.

I still haven't gotten a oil guage yet. grrr.

Doesn't Porsche use like 0w60 or something like that? I have the same problem and Im trying to get rid of it. Maybe if we could find like 5w50 or something it would be good for start ups and good for the lifters when it warms up.

If you're running the 48 gram lifters, it has been my experience that you do need to run a heavier grade oil. In a synthetic I found the Shell Rotella T Synthetic 5W-40 works pretty well. It gives you a couple extra pounds of oil pressure on the top end which is never a bad thing. I also ran 15W-50 once as an experiment. It did completely eliminate all lifter tick, but I think it was a bit excessive.

they may be sticking a little, too. i had some lifter tick when i put mine back together and a can of BG MOA took care of it.

They are a little louder than the injectors, but its noticable. I will be doing an oil change soon and will change to a little heavier oil

They are loud! Sounds like a multiple clacking going on under the hood from the 3.4 I know of that did the swap. Heavier oil did take some of it away, but it's still loud at idle or coasting speeds.

I got 1000 miles on my motor, but I started to notice that the lifters are very, very loud. I have full oil and it does it all the time. Are these lifters know for this or do I need to run heavier fluid
