oil pump

[windy1]

how do u,change an oil pump,on a 91 festy? the haynes manual,says u,dont pull the engine,just oil pan and front sprocket ? :cry_smile:drool:nono:

[Larry Hampton]

I need to change one out as the mount for the timing belt tensioner is bad (its at an angle

Do these tend to go bad? Will one off an Aspire work?

I have a Ford manual, says crankshaft socket, oil pan, then pump. Pump bolts are 14-19 foot pounds. Inlet tube is 69-95 inch pounds. If you follow the sequence, they pulled the engine, but I think it could be done with it in.

The oil pump fits over the crankshaft and bolts to the front of the engine. Make sure when you order your pump that you know if you have a "big nose" or "small nose" crankshaft. Normally, all '93 Festivas and a few 92's will have the "big nose". Anything older will be "small nose" unless someone has replaced the crankshaft. The Haynes manual is correct, except there are a few more pieces than you list - crankshaft pulley, timing cover, timing belt, and probably drop the exhaust pipe from the header manifold.

you don't actually have to pull the oil pan, IIRC, but there are 2 or 4 bolts that go through the front of the pan, and a seal that's a pain to seat properly if you don't pull the pan. Up to you if you want to try it, but you'll likely end up pulling the pan, or at least lowering it.

The whole job shouldn't take more than a couple hours if you're experienced with that type of pump. The hardest part about it is setting the valve timing. As long as you're putting a new oil pump on, you might also change the timing belt tensioner, water pump, and belt, depending on their age.

I never saw any sitting at an angle....usually the pulley gets to feeling rough when you try to spin it or it may get kind of "growly". Aspire should fit just fine --- if you have a "big nose" crankshaft on your Festiva. If you have a "small nose" crankshaft, the Aspire oil pump will be way too big for your crankshaft.

oil pump

i was going to replace oil pump ,when i replace pan gasket. engine has 165,000 miles. actually,if pump is good,and it seems ok,why should i replace it? i was going to,cause i have to do pan gasket. if pump works fine,why replace it? what u,guys think? thanks for great feedback,guys mdoyleufo@gmail.com

I don't replace anything that still works reasonably well. If it's already on it's last legs, or doesn't perform within a good range (arbitrary, based on opinion), I replace it.

If your oil pressure isn't low, I wouldn't bother replacing it. Same with the water pump. If your cooling system is functioning as expected, no reason to replace it (Unless there's marks around the weep hole, then the seals are bad.)

Timing belt, if it doesn't look stretched or damaged, I put it back on, don't even care about orientation. So on, so forth. I've reused gaskets without problems. Just inspect and test as much as you feel reasonable. You'll get a feel for what's generally in need of repair/replacement and what's not.

If your pressure is fine, leave it alone. This type of pump really doesn't wear out persay. If you were doing a rebuild after a bearing failure where large chunks of metal was getting sucked up, then replace it and dobt chance it. But as a maintenance part, save your money and just do the gasket.

No rebuilt pumps either and with something this important buy a back up
with a spare set of tools for the glove box!

makes sense

u speak right up,usually right too. i should ve had oil pump put on,when timing belt was changed. [if the dog didnt stop to urinate,he d still be alive]

[windy1]

i agree,but its got 165,000miles [hard] on it. i might have oil pressure checked first. if its good,and it should be,ill decide then. i get compulsive,about fixing a car. festy is no exception. thanks for tough advice.

[Rocketman]

So you've no reason to replace it other than you feel like it might need it?

Leave it be. Do the timing belt/water pump if you're worried

[windy1]

right and correct. keep your powder dry,and nose to the wind. thanks

I never saw any sitting at an angle....usually the pulley gets to feeling rough when you try to spin it or it may get kind of "growly". Aspire should fit just fine --- if you have a "big nose" crankshaft on your Festiva. If you have a "small nose" crankshaft, the Aspire oil pump will be way too big for your crankshaft.

It looks like the tensioner was put in cross threaded. It's at a pretty extreme angle, like 15-20 degrees off square as I recall. It's sorta hard to get to right now to take a pic. I'm thinking maybe the boss cracked off and the bolt pulled over.
