Lifter tick

[Ogleorama]

Ok I'm new to this because I have just recently bought a 2005 serria 1500 crew cab slt. It has 230000 miles and had the engin rebuilt 40000 miles ago according to the seller. I have noticed that when I cold start it, after about 10 min. It will start making what sounds like a lifter tic. The oil pressure sits at about 30 psi. When I drive it for appox 15 min the tic goes away and the oil pressure goes up to 40 to 45 psi. Now I can stop and start it the rest of the day and never hear the tic again. If I cold start it again the next day it will do the same thing. Do I change the oil sending unit or is this something else. I used the sea foam because some guy at the auto parts store told me it would help. So I did and then change the oil after Appox 2 days. Still doing the same thing everyday. Any thoughts?

I have the same issue on my 03 1500 with 80,000 mi, I have seen this flush recommended by many. http://www.amazon.com/Motor-Medic-Gunk-Mileage-5-Minute/dp/B000AME4V4/ref=sr_1_1?ie=UTF8&qid=1428261740&sr=8-1&keywords=engine+flush. I know you did the sea foam already but from what other have said this should work. If you want to wait and see how it works for me you can but you will be waiting two more months until I change my oil.

Thanks for the feed back xXZ-71Xx. I would love to hear back from you if you don't mind. I just want to know what the issue is. Thanks again.

I have almost 300,000 on my original motor, and it does it everyday. It's never gotten worse, so I just let it go at this point. Once it gets above 3,000 RPM's, it goes away as long as the engine stays warm like you have stated.

 

I'm also interested to see if the "flush" improves anything.

Ok, I will report back here what Happens afterward.

Drain a quart of the old oil out, and replace it with a quart of transmission fluid or marvel mystery oil, run the engine in park for about 15 minuets, raising and lowering the idle.

 

Drain the old oil and replace the filter along with new oil, if the lifter tube was gunked up or blocked, the previous method should take care of it.

I have a 2002 gmc sonoma v6 4.3 with 175k and It has a tick mainly just when it idles, some days it ticks and other days it don't tick loud. I have been expeimenting with different oil additives like rislone and marvel mystery oil and nothing really seems to help much with the tick although I did drain a little oil out and add about 2 cups of automatic transmission fluid and I noticed after a few days of driving around that the tick would actually disapear even when I was just idleing in park, It seems to be cleaning my engine up. Tomorrow I plan on draining atleast 2 quarts of oil out and then I am adding 1 new quart of 5w30 and then I will add the 1 quart of transmission fluid and I am going to let it idle for 20 or 30 minutes and then drain it and put a new filter on and fill it up with mobile one high milege 5w30.

That tick seems to be a staple of 21st century GM V8's. Mine started doing that at between 30k - 40k miles.

Thanks for all the feedback you guys are great. I might have to try the ATF on my next oil change, or the marvel. I noticed that when I cranked it up yesterday that it didn't even do it once. It might do it when it's cold weather. Again thank you for your comments.

I decided to run ATF in my sonoma v6, I ran 1 quart ATF and 4 quarts oil for about 25 miles atleast and it ran well and it did silence my lifter tick quite a bit. The tick is still there but it isn't as loud as it was. I ran it for about a day and then the next morning I warmed the engine up and drained it out and put a new puralator filter on. When I drained the oil I got some crap out of there that wasnt supposed to be there. I think overall the ATF is a good treatment but from what I see its not a miracle cure like a bunch of people think, It seems more like a thearaphy so I will continue to use the ATF before every oil change in an attempt to completely rid my engine of that damn lifter tick.

If their is junk in your engine, a repeated treatment should cure the entire problem.

That is what i was thinking. I think I will run the new oil for a few months and let the mobil 1 oil additives work a little before I hit it again with ATF.

Ok I was told to put a different oil filter on and it would help. So I put the AC delco on as recommended and now the tic won't go away at all. The oil pressure won't even get up to 40psi now. I'm going to switch back to the filter I had. My question is why is it when the oil pressure gets up to 40psi the noise goes away. Everything points to a oil pressure issue, so what is causing the oil pressure to be low. I feel like if I could figure the oil pressure issue out the I could fix the problem. Any thoughts?

I haven't had a Delco on my truck since it was owed an oil change by the dealer for smashing my truck up during a warranty brake service ....

 

I've been running K&N filters since I did the second oil change (bought a huge batch of them at a deep discount - STILL have many left 8 years later). My preference is Purolator Pure One filters.

 

The way I look at it is the same way I look at motorcycle oil & filters - manufacturers are in the business of selling bikes / cars / trucks - not to make your engine last forever. OEM oil and filters are the last things any of my equipment gets. Just MHO - been working for me for 25 years. Amsoil and Purolator - that's all everything gets here.

Are you sure it's not piston slap?
