That's the reason, when I heard it I was like oh noooo lifter problems again? Should I reset my ecu after I use this Techron stuff? Thanks!
Ticking injector noise seems to vary.....You should hear a 1.8T Turbo VW/Audi motor! They are, after all, just electrical solenoids being opened and closed.

Techron is good to keep your fuel gauge senders AND fuel injectors clean. I generally do a bottle at every oil change. No need for a reset.

O/T Ya that car was a dream, I could drop clutch it at like 6800 PRM and it was gonzo! I ended up dropping the tranny after about 138000 miles, replaced it and still sold it for $14000, mind you I bought it off my ex girls mom for $11,000 and it had 56,000 miles on it. It handled like no car Ive ever driven (except of course my Z :icon17: ) it was so nice to say :gtfo2: to my scion!!!

I did hear it when i bought the car, but it doesn't tick anymore. Weird. Hopefully yours goes away too.

Oh happy day if/when that happens!That's my only real gripe with this car.

I just added a bottle of techron concentrate plus and a full tank of 91 gas.
Thanks SoCal 370 for that recommendation. Lets see if it helps.

If the noise persists and it continues to bug you feel free to drop by the shop and I can have one of my tech's listen to it and give you a quick answer. We're just by John Wayne airport so it's pretty close to you in Irvine.

Has anyone successfully rid the tapping noise after completing the TSB for the Heater core flush?

No name brands don't worry about their reputation only there costs.

Ever wonder where the gasoline/diesel blending mistakes wind up going to?

Point to ponder: Ever wonder why there are no name branded Jet Fuel distribution companies at airports? It's called liability. The Jet fuel companies are responsible and accountable for their fuel quality they put into a airplane. Reputation, accountability and not to mention lawsuits are powerful motivators.
AVGas???
BPAir??
Shell??

My car still has a valve tap like crazy. Took the car to the dealer and listened to another 2010 Z with the parts and service manger, and it sounded somewhat similar, but my engine def sounded louder and more tappy. He is having a field service engineer come out on monday or tuesday to listen to it. So help me god if he tells me it sounds normal. I'm gonna try and record it see if anybody else has similar sounds. :shakes head:

maybe it is from the race gas you are running... i wouldn't tell the dealership you put that in your car.

Ticking can also be attributed to oil starvation due to the oil plumbing design wormed throughout the rear part of the heads located next to the firewall when reacting to the centrifical forces from acceleration. I haven't ever heard of this on a Z but it has been problematic in other car models.

This is why I like doing my own oil changes. Half the time you don't know what the dealer/quick-lube is filling with. I don't trust most service managers\techs at dealers, so even if they told me they filled with the requested oil I would still be questioning their trustworthiness.

It was happening before i put race gas in, and my dealership doesn't care I used race gas, it has nothing to do with warranty.

Ya I just purchased my Rhino ramps, and all my tools so I can start doing my own changes. I should have sharpeed the oil filter before my first oil change. Especially since my first one was free, I'm assuming they didn't use Ester oil or change my oil filter since I went in at 856 miles. Well I didn't mean to turn this into another oil thread, but I'm switching to Redline after 5000 miles. I had the tapping before, went in, they tell me ester oil will rid it completely, and it obviously did nothing.
