I replaced my oil pump last night and I have a few questions.

I used Permatex anaerobic sealer (red stuff) and I went all the way around the pump, and not around that circle on the bottom left (see how it goes around and back out to the outer edge), I was told to just do a decent bead all the way around the outer edge.

EXAMPLE:


By not getting that ridge in the bottom left, is that harmful for the pump?

Secondly, the O Ring. I didn't have an O Ring but needed to replace it cause mine was shot, my shop had a bunch of engine seal kits and I grabbed an O Ring that fit perfectly in the block and it had like a little inner lip to it which is what I heard the O Ring has. I'm almost positive that it was the correct O Ring but if it wasn't, can that be harmful as well? I replaced my Oil Pump because i'm having oil pressure issues to my lifters.

Thanks

This pic is from the FSM (same as your example):


So, based on that, Yes it needs the sealant around that section. Hopefully you've not put it all back together yet??

And I think your o-ring is fine.

Those gold/bronze colored Phillips head screws on the back of the pump can come loose. Did you tighten them on the pump you installed?

If you re-do it I wouldn't use too much of a bead. The one in your pic is as much as you should need. You don't want it squeezing out and getting into the oil flow....I think the anaerobic stuff you used is better for that, too.

Oh it's back together, and already driven about 25 miles on it... haha.

Not leaking and seems to be fine, car is STILL TICKING, I figured the oil pump / o-ring was the cause but no help -_- so i'm down to just replacing all the lifters and seeing if that solves it. (separate issue)

BUT the car is running great so far, I hooned around in the snow tonight (was easy on the motor) but for now I will be light on it until I do my timing belt and i'll re-seal the oil pump then.

So just out of curiosity, When you get an oil pump gasket kit, from say autozone or schucks, it comes with a paper gasket. Should a builder not use the gasket at all and ONLY use the sealant?

Just use the sealant.

Thanks for clarifying that for me.

BTW for everyone else, an Oil pump seal kit has the gasket, o-ring, and front main seal for a better price than just asking for the front main seal at a common auto parts store.

Yes, as with the oil pan you do not use a gasket. Also, it may not be leaking yet but I see a leak I. Your near future if you did not seal that large hole on the bottom left. The lifter tick could be fixed with some seafoam or kroil in your oil for a hundred miles.

So is the picture in your first post yours? Maybe I'm blind, but it looks the same as what the FSM has?

Also, the FSM calls for permatex ultra-grey to be used rather than anaerobic sealant

Kimo, no cleaner is gonna fix it. I've tried it all..


Josh, the picture is an example, I did NOT seal the bridge in the bottom left, as the picture shows.

What are you calling the "bridge"? That whole lower left section?

Yes, that lower left section that goes across. I didn't seal that. I sealed around the entire pump, but not that lower left line.

That is actually the "suction" area of the pump. I'm kind of surprised it's not already leaking. However, it may also be contributing or masking your problem. Since that is the suction side it may be drawing in air and not getting as much oil flow through the pump and the engine as you should.

I would highly recommend you pull the pump off, clean it, and reseal it.

Roger that, gonna go back to my shop tonight and get it done.

Let us know how everything goes and whether it makes any difference with the lifters.

Just out of curiosity, how does your oil look? Does it look frothy or have bubbles in it when you pull the dipstick out?

I will let you guys know.

Also, my oil looks nice and clean. Was just recently changed, too.

Robert, where did you get the sealant? Im at autozone and am not seeing it.

Never mind, I had to order it online. Oh well...

My shop just had the Permatex Anaerobic RTV on the shelf, i'm not sure where locally you could get it. I was gonna say online is your best bet prolly, but ya beet me to it.

Sure did! 20 bucks for a 50ml tube

Ouch, at least you don't need a lot of it!

Yes I do unfortunately. I have 3 blocks to build at the moment...
