2005 Avalanche 5.3 lifter tap

50

Asked by Apr 17, 2016 at 10:41 PM about the 2005 Chevrolet Avalanche 1500 LS

Question type: Maintenance & Repair

I have a 2005 Avalanche with a 5.3, I have
200000 miles and have used Mobil 1 oil
since the first oil change changing it at no
more than 5000. Starting at about 198000
I started to hear the valve train at startup
and has now turned into a intermittent
lifter tap(that's what it sounds
like).Driving on the freeway at 2000 rpm
after about 15 min the  lifter starts to
tap(it only sounds like one lifter), and
when it idles for about 5 min.I hear
people say that the motor may have a
blocked oil passage preventing the lifter
frm getting enough oil. Has anybody
figured this out yet.I took it to the dealer,
paid for the diagnostic test and they told
me it needed a cam and lifters for
3700.00.I guess I will drive it until it dies.

you could try a motor flush and then try some of the engine treatments out there, you haven't much to lose. Rislone makes a good one, so does STP and marvel mystery oil. lots of choices, wouldn't hurt to try.

If you have used Mobil1 since new changing it every 5,000 miles, it would be my guess that the inside of the engine is pretty clean. Probably is a sticky lifter in need of replacing. As "Mike" said it is possible that a dose of Rislone might fix it, but I don't have much faith in additives.

Agree completely, but not much to lose. Trying an additive is cheap compared to putting nearly 4 grand in an 11 year old car with high mileage.

Thank you for all of the suggestions, I failed to mention that I tried MMO and another time I used Lucas oil stabilizer with an oil change. When the dealer mentioned that I needed a cam and lifters I thought that was strange because it was an intermittent issue. When driving on the side streets it rarely happens, mostly on the freeway and because of that I was thinking it might be a oil pump.But an oil pump will cost me anywhere from 600 to 900 to have a shop do it and not know if it would work. Thanks you for any further help on this issue.

If you suspect bad oil pressure, it wouldn't hurt to check it with a gauge. Ericthecarguy.com has a good video on how to do this, then you will at least know if oil pressure is an issue. It depends on your situation of course, if it were me I would make sure the oil pressure is up to snuff and throw in some rislone and use a good quality synthetic oil, and drive the old girl. I understand though, spend 4 grand on an older car or risk losing the engine and then its worth nothing. Good lubrication will take you a long way though.

Finally fixed it, I dropped the oil pan to check and replace the oil pickup o ring and it was in three pieces. No more valve train noise and gained 20 psi oil pressure. If you hear your valve train at startup or have an intermittent lifter tap and you have an ls motor you may want to try changing the pickup tube o ring. It worth a try costs are oil pan gasket, some gasket sealer and the $ 3.00 o ring. Thanks for all of your help.

Great to hear that it is fixed and didn't cost an arm and a leg. Well done!
