Default Aftermarket lifters?

Anyone try any of the aftermarket lifters on RockAuto?

Lifter noise on driver side bank of VG30E until engine is warm.

The Hitachis OEM are pretty expensive....

I hear the risk with the aftermarket parts is the metal used?

Alternatively, anyone have any luck removing and cleaning their current ones?

Ive had bad luck with OE and aftermarket lifters. I've had back luck when cleaning them.



If you have noise until the engine is warm that means oil isn't getting to them and they are not pumping up to pressure. Make sure your supply is clear. Make sure you have enough oil pressure.



My truck makes 60+PSI cold and still clatters for a couple seconds when it has sat for a few days.



A quality oil and a filter with a proper antidrainback valve will reduce the issue.

Ahhh shit. That’s not the news I wanted to hear....

I guess first step is install an oil pressure gauge....

Possible to clear the oil supply line from valve cover end? Rather than having to drop the oil pan.

You will need to drop the pan and pull the water pump. Pain in the rear.

I got the Hitachi lifters. Expensive, but they are working good.

I think JP means oil pump.





I've mostly given up on lifters.





You can try to clean from the top down with air or solvent but you'll still have to drain the pan. There is a screen in the pan that can clog and depending on age, maintenance schedules and miles an oil pump may not be out of the question.





I've got a mechanical gauge for oil pressure. Cold idle on my truck is 60-65PSI. Hot idle is 20-25PSI. Cruising highway speeds, 2500RPM, is 55-65PSI depending on engine temp. I have seen up to 90PSI.

I think that water pump (in my hand in the picture below) needs to come off to get to the oil pump (silver part still on the engine in the picture below).



Below you can see where the water pump was and where the oil pump still is. I did NOT replace the oil pump on my engine while it was out.



For your VG30e engine, your oil filter will be on the other side, in the back, so that oil can dump on the starter. The VG33e engine moved the oil filter to the front of the engine.

Would be a lot easier if I didn’t have to drop the front diff just to get the oil pan off.

You don't have to drop the pan for the water pump. You do for the pan. It sucks.

Fixed that for you.

But my point is, I think you have to take the water pump off in order to get the oil pump off.

I'm not 100%
