What's the typical life on a EA82T oil pump? I tore down and took the pump apart (oil is everywhere on this car) and it looks ok inside but I didn't mic anything out or check clearances. Wondering if the new seals will fly or I need to replace the whole thing (at least $100).

 

Thanks!

very subjective topic, here's stricktly my oppinion and experiences...

 

there really isn't any replacement interval on these. in my experience approaching 200,000 miles is a good time to consider replacing on NA cars. maybe a little sooner for turbo. the clearances and pump performance have always remained excellent on mine with no wearing/pumping issues. but i have had two fail in other manners (still have those pumps)...the ball/spring combo internal to the pump broke on one...not sure what causes this, but that's the only failure mode i've experienced. it's like the ball busted past the casing of the pump....hard to explain, but look closely and maybe you'll see this ball/spring that i speak of.

 

if you do a rebuild, i'd definitely replace. no point in having a perfectly good block and put a questionable oil supply on it. if you're planning on keeping the car for another 100,000 miles or more then i'd install a new one as well. i figure using an old one for 100,000 miles is a risk. but a new one should have no problems going 100,000+ miles, so replace it now as it's highly unlikely you'll ever have to replace it again, but likely that you should at some point if you're planning on lots of miles. i drive 30,000 or more miles a year so i can rack them up quick. someone who drives much less might not care too much about total miles.

 

with low mileage....maybe around 100,000 roughly on the motor/pump (again these are just random numbers that everyone will have different oppinions on).....i think you would likely be fine to wait until the next timing belt change at 160,000 to do it.

 

then again....you could likely install the old one and have it last a long time, there's just no way to tell.

 

if it's really low miles or you don't plan on having the car long or putting many miles on it, or don't have the money that's the only way i wouldn't replace it if you've got it apart at this point.

I've had a couple of them go over 250,000 miles. The only thing I've done is periodically reseal the pump. My current EA82 carbed has 253,000 miles and still puts out 10-15 at idle and 45-50 at speed on a warm engine.

Given the ease of tear down to get to oil pump, I'm going to go with just resealing it and figuring out what other problems the motor may have first.

 

Thanks guys!

The biggest problem with resealing an old pump is that the shaft gets a groove worn in it that can be quite problematic. I tried resealing a pump with 140k on it, and it started leaking less than 5,000 miles later.

 

Take a look at the shaft, and if it's worn, replace the pump. If not, go for a reseal.

I'll double check on that groove, if so I'll replace.

you could try buying a used shaft from someone as well, or a used oil pump if you want to run the motor a bit and see how it responds before dumping $ into it.

 

but even if you didn't like the motor, you could get another motor and swap the new oil pump into any new/used motor you get.

 

i bought a new oil pump this summer and the motor i just finished...grrr...was toasted, locked up after hitting some firewood left in the road. i'm putting together another motor now and will swap the new oil pump off the bad motor before installing the new one.

That's kind of what I was hesitant about, bad motor, another project. My GF will kill me as my Turbo Neon has been about 95% finished for a long time.

have you replaced your headgasket today?

Certainly, it was a full build after hydrolocking a rod into a banana.
