Oil pump

[threatminor]

By chance, has anyone attempted replacing the oil pump by themselves? I was considering it, and after glancing at my FSM, it appeared to be quite job just because of how many other things have to be removed. Also, if doing this job, any suggestions on what other stuff would be a good idea to get done at the same time?

How many miles on it? I'm far from being an expert, but I just rebuilt my motor with 170k on it and the oil pump looked like new. What kind of symptoms are you getting? As far as changing the pump internals, I think all you need to remove is the idler pulley and crank pulley, then the phillips head scews that hold the cover on.

hmm

well, it just seems like my oil pressure is close to being to low after you've driven it for a little bit, and it has brand new oil and oil filter and the fluid levels are all good.

maybe it's normal

I just noticed that post on the sort of the same thing above me, and it seems as if it might just be normal for it to start running lower once everything warms up.

3FE or 1FZFE?

1FZ

it's 1FZ

The 1FZFE usually runs low on the gauge at low RPM. Since you mentioned you have a service manual, look up the correct oil pressure. Remove your oil PRESSURE sending unit on the passenger side of the engine, and do an actual reading with a real oil pressure gauge.

If you want to continue to get accurate readings then install an auxhiliary gauge that will read actual preasure and not just a low to high range.

One other thing. The oil LEVEL sending unit is on the drivers side down by the bottom of the block near the starter. This is different from the PRESSURE sending unit on the passenger side toward the front of the engine.

Guess the miles remain top secret?

hm

Miles are 172,00, definately not low, but hopefully plenty of life nonetheless.
