2005 Tahoe Z71 Lifter Ticking that goes away with Oil Pressure isues??

35

Asked by Jan 31, 2016 at 08:59 AM about the 2005 Chevrolet Tahoe Z71 4WD

Question type: Maintenance & Repair

I have a 2005 Tahoe with a 5.3L. It has the lifter ticking when first started and normal oil pressure, The ticking keep s going for about 5 to 10 miles until it warms up. During this time the oil pressure gauge never goes above half way. After the motor gets good and hot the lifter tic goes away and the oil gauge then goes above half way and starts to move with the engine RPM, as it should. I tried an engine flush and marvel mystery oil but it doesn't seem to have made any difference. The truck has great power and acceleration. I don't believe its rockers or push rods because the noise goes away. But after the ticking stops and if I pull up to a store and let it idle while I run in, when I come out it is ticking again, but stops as soon as I start driving again for about 20-30 secs.. I have noticed that during the time after starting it and driving while its ticking, if I come to a red light I have seen the pressure drop to the warning lvl. but that has happened only a few times. Any help with this issue would be greatly appreciated.

It may be a weak lifter, about the only thing aside from replacing is to find which one it is and adjust it. That may or may not take care of it. I think I would keep on with the oil treatment for the time being, trying to remove any varnish and adjust, check the rocker arm for adjustment.

Any ideas on why the oil pressure would not go up until the ticking stopped?

Just got back here, out in the garage lighting a fire, Well, depending on what time of year that motor was manufactured, it was at this time I believe 2006, may be 2005, can't remember. but GM put a fine screen type basket under the oil pressure sending unit that does get gummed up causing false pressure readings. It may be yours has this. You check by taking out the oil pressure sending unit, and then have to fish out this screen. Then clean it good, and replace. Since you have to be a monkey to get at this, you might as well replace the oil sending unit while you have it out.
