Sorry for the error. This is a 16 valve engine so you would need 16 if you were to replace all.

For an experienced mechanic, he should be able to determine which is bad or failing after removing. Visual inspaection would have to be made on the rocker arm side as well. Any abnormal wear would not allow the lash lifters to be seated correctly and result in oil pressure loss.

I was just thinking myself, "isn't there one lifter per valve? And 4 valves per cylinder? Maybe 2 cylinders have 3 valves." Haha, thanks for clarifying.

So my bad mechanic will be able to determine what option is better for me, replacing some or all of the lifters. I know you will say to replace all of them, but what would you do in this case? The labor would be the same for replacing one as it would be to replace all of them, right? The abnormal wear would be caused by what, exactly? Auto-Rx? Switching from dino-oil to synthetic?

That would most likely be due to wear and tear over time. If lubrication had not been a problem, there would be minimal wear. Whatever oil used does not matter much, the condition of the oil would be the man concare. If oil change had been regular, there should be nothing much to worry about, unless there is clogging in the system.

For me I would service all the lifters and replace only those that are faulty but in your case it is different, servicing the lifters is going to cost you more than the lifters due to the labor cost factor.

Replacing one and all would be the same time as removing the rocker shaft would mean taking all out. If the rocker shafts do look dirty, it would be good to have them cleaned internally, especially the small holes where lubrication is provided for the rocker arms.

Regarding the lifters, a quick dose of Seafoam through the brake booster vacuum line solved the noise issue. My local auto shop teacher runs a Mazda Miata-only repair shop and said that a lot of these types of engines get carbon build up on the backs of the valves, not allowing them to close all the way (causing the lifters to be pushed more by the cam, hence the noise sounding like a lifter failure).

My current question is regarding the four speed automatic transmission in this car. My records indicate that the transmission fluid was flushed on 04/07/2007, with 79,584 miles on the vehicle. I am wondering if it would be better to get the transmission fluid flushed or exchanged. In other words, would it be better to drop the pan and drain the fluid, or to connect it to a flush machine and have it changed that way? The transmission still shifts fine, and the fluid is just slightly discolored (pinkish-grey), with little to no burnt odor. Let me know, thanks!

Some impurites or fine particels gets lodged at unaccessible areas and are best left alone as they are not going to dislodge themselves but flushing with machines can dislodge them and cause more harm than good.

I would recommend dropping the oil pan to replace the fluids together with the fluid filter.
