Engine knocks-help needed

[appe]

Hi!<BR> <BR>Car: -92 V6.<P>Problem: The engine ticks/knocks. I have tried to change from syntetic to ordinary mineraloil. The sound stays the same.<P>One mechanic told me to buy new valvelifters.<P>Is that the problem?`<P>

I have a ticking noise from my engine as well...David Coleman told me that it was my HLA's, and that all K series engines do that after a while. He recommended that i use 5w30 oil, which i did, and it got rid of my noise<P>------------------<BR>~'94 GS (Creek Blue Mica)

Can you tell me what HLA's are?

[pelado]

HLA - Hydraulic Lash Adjuster<P>This is the device that sits atop the valve and that the cam lobes ride on. One HLA per valve = 24. It's the same concept as a hydraulic lifter in a pushrod engine. It keeps you from having to adjust valves as with a mechanical setup like on the 240/260/280Z's.

you might also want to check your timing belt and your hydraulic tensioners... i just got mine replaced and my car is so quiet at idle speed that i have to step on the gas to know it still runs...to do that it costs around $ US 500. yikes !<P>------------------<BR>Frenchguy0<BR>'92 GS Emerald Green<BR>crenia@hotmail.com

I notice a ticking about once every month or two. I check my oil, and it's low. Make sure you're up to date on an oil change, and your crankcase is filled up. That should help with ticking.
