Default loud ticking noise after turbo installed?

My car has always had a ticking noise to it but it was nothing major and I've heard quite a few other subarus with the same ticking. Ever since I got the turbo put on, the ticking noise is more then twice as loud as it was. I changed the oil to 20/50 Castrol GTX but it didn't quiet it down any. Once the car is warm and has been run a bit the noise is still there but not as loud but still louder then before the turbo. My installer told me it was my valves and that it was normal, but something just doesn't sound right to me. Has anyone else experienced the same thing?

you are running 20w-50 motor oil??? holy crap man...that's why, you're hearing your valves clatter, they prolly need an adjustment but running 20w-50 motor oil isn't gonna help that at all.

i think 20w-50 is a lil excessive, as long as you add an oil cooler i have yet to see a need for 20w-50 in a street driven car.

might be the valves, and the open intake, and all the metal piping is just amplifying the sound.

Here are what the lads overseas taught me, and it worked well:

10/40 if you are hard on it, 20/50 if you are really hard on it!@ Considering he ahs an '01 that is turbo'd, even at low boost, I would use either the 10/40 or 20/50

I use Redline 20W-50 as well, ever since turbo'd.

For daily driving, I could probably use anything, as I don't drive agressively on the street. But at the track, the oil temps climb quite high, so I figured 20W-50 was a good thing.

I don't have an oil cooler, but coincidentally, was just talking to someone who suggested adding one as well. Probably a good idea without much downside.

RS2000,

Keep a close eye on cylinder #4. I hope you are running some sort of Timing controll. Check out my OUCH! thread and you will see what I mean. I am running 10/40 right now with low oil temps. I see anything from 150-180 degrees on an average day and average trip. This is normal driving, city and highway. Atleast till I blew her up...good luck.

Paul...

hayscoob, thanks for the warning but its under control. I'm running a tecII and have had my fuel lines rerouted and upgraded to help prevent any damage. Nothing is for certain though, anything can still happen but I've done all I can do for now.

lucky you say, more like broke now, lol. But its worth it in the long run. If you got to rebuild anyway, you might as well make it a beast. Do it all. I looking now into having a motor built for my car that can handle about 400 hp. This way I should be able to run it at around 320-350 with no problems. Or so I hope anyway. Good luck with the rebuild.
