oil warmer part that the oil filter mounts to

[KeystonePowderCoating]

What is the technical term for this part?

I have what appears to be one from a very low mileage engine that has been buried way back on the shelf in my shop now for several years.

The main problem is that it is absolutely filthy with dust.

I used some carb cleaner and sprayed it out, but I can still see crud inside.

Here are the questions.

1. In warmer temperatures, keeping the oil cool seems to be a necessity for engine longevity. In colder temperatures (Pennsylvania winters) is this oil warmer necessary?

2. If it isn't necessary, can it be bypassed?

3. If it is necessary, is there any way to make 100% sure this oil warmer is thoroughly flushed out. Seeing how it appears to have been crimped together when manufactured, there doesn't seem to be any way to tear it apart.

4. Last, and I assume this is probably the correct answer to this thread, should I just toss the oil warmer and buy a brand new one from ford. The one on the engine that I'm having rebuilt appears to be corroded more than average. Does anyone know the going rate for this part or if there are any quality aftermarket ones being made?

More than likely, Ford discontinued them a few years ago and there are no aftermarket companies making them. Isn’t that how it goes in sho-land. LOL

Thanks in advance!

In the summer, you need it to keep oil temps down, and in the winter, you need it to get the oil viscous sooner. That said...

I have one for sale, and it's crudless. Shoot me a PM if you're interested.

It's actually an oil cooler. I had one that was completely trashed, but cleaned it in the parts washer and its as good as new. Don't forget to remove the small (inner) and larger (outer) seals out before you clean them. You can still buy the larger seal, but the smaller one is long since obsolete.

It's actually a heat exchanger. It *helps* heat the oil when it is cold and cools (or tries) the oil when it is warm. I just pulled mine in favor of a real front mounted oil cooler. With that said, I could get rid of mine for cheap and it is very clean.

The mounting stem of the V6 SHO oil coolers has a very neat mechanical viscosity bypass valve that allows cold, viscous oil to bypass the cooler. This allows the oil to warm more quickly from a cold start, and probably helps to keep cold oil pressure spikes from damaging the cooler. Once the oil warms and the viscosity drops, it will flow through the cooler.

Jason, are you only running your car during the summer months for the reason that you are removing this part altogether?

Some people are looking at it as an oil cooler for summer months and an oil warmer for winter months.

I'm more worried about if I remove it, is the oil not going to heat up as fast in the winter months causing premature engine wear.

Also, correct me if I'm wrong, but isn't water temperature always warmer than oil temperature, meaning that in actuality, the "part" never truly acts as an official oil cooler simply because the water being ran through it, is warmer than the oil even in the dead of summer.

So if what I said is correct (my luck probably not) in the paragraph above, AND if the part doesn't do much at all to help warm the oil, then technically I'd be better off just running without it. However, I'm sure if that was the case, the techies at Yamaha wouldn't have stuck it on there in the first place.

Also, if you did remove it, how does the oil filter mount to the block? Even if you are going with a remote oil filter, did you use AN fittings or something on those lines.

I'm just testing the waters to see what all options I have.

My biggest concern is if I remove this part, is it going to cause premature engine wear.

From what I've read so far, it seems as though we have some mixed ideas.

By the way, thanks to all who have replied.

No, the car is run in cooler weather too. As Gary mentioned above, when the oil is cool, it bypasses the exchanger all together.

As far as removing the piece, you have to have the threaded insert/****** cut and welded so that you can mount a filter straight to the block. With that, you can mount just about anything you want.

I used to have remote filters, but have removed them, as well as the Accusump.

I won't be running the cooler by itself. I'll be running a thermostat to control the oil temperature. Just like the stock piece, it will bypass this when the oil is cold.
