2004 tahoe hit 100k .. Now I hear ticking

[Superman04]

Hello new here but I got a question I recently switched to part synthetic and run lucas oil and gas additoves but im hearing a ticking noise when I start the motor on the passenger side but only last about 30 seconds and it sounds good what could it be? Running CAI with flowmaster 40 series please if anyone can help so I can stop freaking out lol

mine does the same thing for the first 30secs on cold starts.. dont know what it is, i can only assume its the oil taking too long to get to the top end of the engine

yes mine does the same thing when its cold. i was told it could be my lifters. the mechanic told me to just keep my oil change and i should be fine till im ready to get rid of it.

It is the oil you are using. The oil is not "sticking" to the lifters, etc well enough to protect them at cold start. The 30 seconds between starting and the noise stopping is the time it takes for the oil to be pumped to the valve train. To stop this I would run a full synthetic oil, synthetics have additive properties that make them stick to the internal parts of the engine for better protection at cold start.

One additional option is to install a "Pre-oiler", which will prime the valve train before starting the engine so you avoid the dry cold start situation in the first place. Amsoil use to offer one but discontinued them for lack of purchasing/ordering. But there are others available. Below is a link to one example.

I use synthetic now but still here the knocking. how much does the pre oiler cost.

 

[rjenvision]

anymore insight

 

[clkelley]

Are you using synthetic or syntehtic blend? Which one? They are not created equal and a blend probably won't solve it.

just recently i had jiffy lube put in mobil 1 full synthetic. it runs ok but i still hear the tick during first part of startup. but after it warms up shes quite as a mouse.

If you just switched and they didn't do a flush to get the old gunk out from the conventional oil then the Mobile isn't being fully utilized. It is still flowing slower than it should because of the residual build up from the old oils. I recommend when you do it again that you do an engine flush before draining the oil, then allow it to drain as fully as possible before installing the new oil. If it has spent it's life on conventional then I would recommend changing the filter to a new one before running the flush to help clean the gunk out a little better, this will also make room in the system to add the flush without fear of overfilling the engine.

Ok Ill try that next time. thanks for such great insite. ill keep u udated on my progress because I need to keep my hoe running smoothly forever. thanks!

Those are some excellent links to look at! I recently bought a Chevy Silverado Duramax and learned about AMSOIL from the Duramax forum. This stuff is amazing, my truck runs far better than pre-AMSOIL flush.

I originally just did the switch from full synthetic, to AMSOIL full synthetic and didn't think too much of it, but did get awesome mileage going from Ithaca, NY to MA about once a month (I got 27 MPG on the highway regularly). Now I just installed an AMSOIL bypass oil filter and can already see and hear the benefits from it!

Just was passing by and saw this post, thought I would throw my own $0.02 in. Cheers! :happy160: Good luck with the ticking noise.

PS. Another thing that might be feasible would be to install a block heater on your truck (thus avoiding cold starts). Also, they are just freaking awesome! There is nothing like walking outside, getting into your car, starting it and having heat within seconds of starting it.

could also be an exhaust leak. most likely the seal between header and catalytic converter or the seal right after it.
