430 water/oil pump seepage

I had the oil/water pump replaced with 13.7k miles on the 430. It was not cheap, part alone was $3.4k, then of course you add labor. I had pictures taken of the leak, let me see if I can find them.

 

my friends 08 scud was replaced when had like 5k miles than again 8k miles started to seep they said leave it alone for now and watch it if coolant on ground.i think most will have seepage from weep hole

 

Not great pictures but you can see calcified coolant and oil leak together on bottom picture

Here was my bottom panel. It may not make it to the floor but it adds up over time

This is not necessarily true. If the Waterpump shaft breaks or if the chain driving the assembly fails, then yes you would loose the oil pump. I have had many of these pumps apart and can speak from experience. The seepage the OP has shown in the pics is from the rear mechanical seal. There are two mechanical seals in this pump The OEM pump seal manufacturer has a 100% air test for each seal for 3 secs. Pressure (outside To inside) is 1.5 bars. Maximum allowable air leakage of 3.5 cm3/min. Test is carried out at max working length after dry running for 2 seconds at 300 rpm.

If you were too look at pump closely( not sure you can see in pic) in the area of seepage, there is a weep hole about half way from seepage point to pump body. If that is wet or there is indication of coolant leaking through that hole, then yes I would be concerned.

That is just my opinion and nothing more.

 

There is also a double lipped oil seal between the rear mechanical seal and the rear bearing of the pump. This bearing is exposed to oil. If the seal fails, then you would see oil coming from a separate weep hole located on the Waterpump body at the centerline of the shaft. This is approximately 1" above the coolant weep hole described above.

 

I had weep on my 07 spider with 12k miles. Mechanic says I can prob wait for a year or two since it weeps very slowly. Just keep an eye out every annual. How much you drive a year also matters..if you drive only 1-3k mile a year then you can prob keep an eye out between service. If you do 10k a year I would prob fix it sooner. The cost to rebuild the pump and labor runs about 3-5k.

 

I’m not the OP but putting up pictures of my pump before I replaced it. Below is a closer pictures of the weep hole that was referenced.

Question for you guys. Has anyone thought about or successfully installed leak detectors under their car? I was on the beautiful Waimea Beach this morning and ran across this new thread.

While I don't have any active leaks under my car, I'd sure like to know if one was to start.

I think they all weep at some point. It's a simple mechanical seal arrangement. Someone on here has put together a kit for circa $300 if you search.

 

In looking at some other posts, the question I have is, how much weeping is considered normal, if any? I've seen posts on here where replacement pumps seep again in 3,000 to 5,000 miles.

This post says some is normal: https://www.ferrarichat.com/forum/threads/f430-water-pump.414962/page-2

Just curious.

The oil/water pump on my F430 leaked and was replaced by the previous owner at 21K miles. It was not a cheap repair job.

I now have 30K miles and so far so good, no leak.

Drive it more often and the seals won't dry out and seep!

 

The waterpump mechanical seals cannot dry out.

 

Perhaps but absolutely everything rots without regular use. Mechanical parts need use or they go bad or mechanisms stick and rust. Fluids chemically reacts faster with environmental water and oxygen. Who knows what impact that's having on longevity? Oil seals shrink, injectors clog with dried up fuel, tires dry out, suspension bushes sag, it just goes on.

I'm saying regular usage where the engine is brought up to full operating temperature makes these cars just that much more reliable. Use them more and they will work better.

Been advised by a mechanic doing annual maintenance for the first time that water pump shows sign of leaking at weep holes. Suggesting replacement for around $2500 pump and $1100 labor. Does this picture look like the seepage is serious enough to replace?
Car is a 2006 430 F1 with 6600 miles. This is a one owner car that was driven sparingly for the past 13 years and has probably sat for long periods without driving and without annuals. It this seepage normal and with more frequent driving will this get better or worse? I noticed from the threads that there are rebuild kits available. Advice please.
Thanks

 

1100 labor is alittle extreme. More like $300-500. Last time I did it it took me (without a lift) 4 hours. I am a slow laborer to be sure.

and yea, its a little serious. I'd replace the seals.

 

Yes, it looks pretty bad. Price for part seems right.

 

Hi, if you are about can u e mail me re water pump kit. Ta

 

Not very many things in a car (any car) will heal themselves through driving more. In the US, the price you're quoting seems roughly correct. Whether you rebuild/reseal that pump or slam a new one in, there's a fixed amount of labor just to reach the darn thing. IMHO, get it taken care of properly and then enjoy the car worry-free when spring arrives.

 

If it ain't broke, don't fix it. If it is, do it right the first time.
Rebuilding the pump is never a sure thing.

 

Water pump seal failures on cars laid up for winter or after any long period of inactivity is very common, so much so I can tell by my calendar when I be rebuilding and replacing water pumps. Clients who use their cars year round almost never have water pump issues.
