Thread: Ticking sound coming from under the hood, Only under acceleration tho...???

Car is a 2006 GPGT and noticed this in February, it hasn't got better or worse but now is really bugging me.. Its a slight ticktickticktick almost sounds like a lifter tick, but not as loud.. Ive seen some people suggest valve lash, spun bearing, seal, Crack in HG etc, but we are going to start small first.. Could it be something like an exhaust leak somewhere? Is there some kind of donut gasket off the mani??


I would take a vid but you would never hear it over the wind noise... But when I get a chance I will go put it in drive and hold the brake to get a load on the motor and see if I can get a sound out of it

But does anyone have any ideas??

once the belt is off spin all the pulleys, make sure they are smooth rolling. test the water pump to by pushing one side and pulling the other of the pulley, if it moves, its going bad.

Thanks man, Actually just did that last week, bad squeeking/ticking, .. Waterpump was shot... So it actually has a new pump and belts, and the rest of the pulleys are good

Coudnt I just dump a little seafoam in the gas tank as well?? Im guessing it would smoke pretty good if there was a leak?

I tried the seafoam trick to find a leak in my exhaust. Didn't see any smoke from the exhaust. Tomorrow (while it's already up on blocks) I'll start it up and feel with my hand around the exhaust, starting with the manifolds.

Yea Im hoping its just a small leak somewhere.. Exactly how do you use the seafoam ? Dump it in the oil,? gas tank? and also how do you get it in the vac line?

Take the big vac line off the brake booster. Engine will studder and die if you don't hold your finger on it. I used a funnel and just kept blocking the hole with my finger as I poured the seafoam into the funnel. Then let the seafoam slowly get sucked in. When you're close to done, pour a lot of seafoam all at once so the engine dies and let it sit for about 10 minutes. Then start 'er up (it'll be hard to start it at first). I actually used the whole bottle doing this. Got carried away but it didn't hurt anything. Quite a smokeshow after I let it sit 10 minutes. Anyway, after you let it sit 10 minutes and get it started, look for leaks in the exhaust from the smoke. This didn't work for me though. Sorry for long paragraph, my enter key isn't working for some reason.

Ill give the seafoam a try.. But now that it was mentioned.... I didnt notice any ticking before I put the cone filter on the end of the MAF

I have a 2000 ssei with a intense level 1 kit w the FW intake, and I dont hear it at all

^mines too. I'm thinking I should get a longer tube. I hate the noise.
