Thats a nice install, may go that way myself, Thanks for the info.

 

I agree nice clean install. How often do you change your oil? And also when you do change so you change both filters at once I would assume correct?

 

What does having the second filter and bypass get me besides lighter in the wallet, and a cluttered up engine compartment and a few more places for potential leaks? I'm not trying to be rude but on my 97 over 290k without the bypass are the 3rd gens failing because of unfiltered oil? Do you run in dusty conditions?

 

i change my oil every 20,000 miles. my oil analysis says i could go longer-but i change it then. i still change the stock oil filter every 5,000 miles and i change the bypass at 20,000 miles- amsoil says it is good for 25,000 miles

 

Three quick q's for ya rjm022...

Do you have to take the hoses somewhere to have the fittings crimped on like a hydraulic hose?
Now that you've had it on there for awhile, any heat issues ever in that position?
Did it drop the soot count in you oil analysis?

Nice setup by the way.

 

I have identical set up with rjm022 except for my pre-charger. I had all my hoses made by a hydraulic shop.

 

I have over 330k on my 04 and had 260k on my 96 never did I have the bypass filters installed, the main reason im interested in it is for extending my oil changes considering since I run hard and put on 3k miles in about 3-4 weeks it would save me both time and money and also heck if I can get even more miles out of my truck why not? I mean I never knew oil could be TOO clean

 

no- hoses and fittings came with the amsoil set up- very easy to install- no leaks in two years
no issues with heat- the only drawback some may see with my set up is- you have to use the smallest amsoil bypass filter (length wise) so it fits- but that filter still holds an extra quart of oil.
soot levels did come down after install- it has been 7 months since my last oil analysis-(can't find it at the moment to tell you the exact numbers) wife is famous for filing away my stuff and i can't find it!- will look of it this weekend!)

 

You've got an edge juice w attitude on your 4.5. The extra performance increases soot levels in your oil plus the new CJ-4 oils most people use nowadays tend to break down faster anyways so the cleaner the better the way I see it. I wouldn't run a truck with a programmer long term without a bypass. Now surely lots of people do and have no troubles but me personally I wouldn't. If you put a bypass on that 97 the oil would never turn black.

 

Just showing my bypass setup because it's a little different than most I've seen here. The filter is on the frame under the passenger door. I tapped the valve cover for the return line. There is a nice boss inside, so I tapped inside it for strength. I also added a gauge to the stock filter housing. It may not last long since there is a lot of pulsation in the oil galley.

 

Anyone know if Tri county mold and machine is still around? Don't see a website anymore? How does this mount to the exhaust manifold?

 

I'm going to chime in - I don't mean to stir things up or be a "Debby Downer" but the following are MY experiences:

I have an FS-2500 bypass and I like having extra filtration - it's a good thing and I don't think really they aren't that expensive. However, I made some mistakes in my beliefs and discovered a few things the hard way,

1. My oil was always black and has never changed to clear. Even with my newly rebuilt engine, the oil gets black.

2. In May of 2013 it was a braided stainless oil line supply coming off the filter housing that made contact with my alternator and started an engine fire. Bypass filters require extra plumbing - so be careful. Check them regularly, because even if the lines are routed well a loose fitting can dump a lot of oil fast. If you don't pay attention your engine is toast. This happened to a friend. Extra plumbing = extra vigilant.

3. When my engine was replaced my new Hamilton cam was found to have excessive wear - only 2 yrs old. The mechanic at DFC suspected it was because I was relying on my FS-2500 too much and should have been changing my oil at the regular intervals rather than extended periods. I always used Amsoil. So I will go back to regular interval changes with this new engine and my new Colt cam.

So for me, I still have my oil bypass on my truck, aiding to protect my engine (which sounds ironic after all the above). But that said, I have a very obvious oil pressure gauge installed, I've made sure all oil lines are very well routed away from electrical and heat, and I change my oil at regular intervals even though I'm told by FS ppl and Amsoil the oil can be changed less frequently.

An $8500 long block and $2000 for replacement is the alternative to making errors on such a simple upgrade.

 

Oh yes, with a modified truck you need to change the oil at least every 5,000 miles and no later. A modified truck creates more soot. The more fuel you put to it, the worse it get's. The bypass does help a good amount. Without it I would be doing 3,000 oil change intervals.

 

This is why I do NOT believe in extended oil change intervals...the extra filtration is great BUT nothing beats good clean oil at a regular interval you save money in the long run.

 

EdmontonCanada: how long were you going between drain intervals? Were you doing oil analysis, if so how often? Assuming something was causing the wear does not mean it was. As you are probably aware, particles that cause wear can come from multiple sources. Relying on a filter alone is not a good idea, backing it up with oil analysis could possibly tell you what the most likely culprit was, so you can fix it before it gets out of hand. My engine isn't modified like yours (one day I hope to do so), but there shouldn't be a reason why you can't run longer drain intervals. I have over 23K on my oil (over 70k on truck) with oil analysis done between 5K and 7500 miles. Each one has come back code 1 for continued use. I'll change it when I order the bypass setup from Amsoil.

Out of curiosity, why did you choose to go with the FS2500? While I like their products (they sent me a very informative packet a while back), what I didn't like was how the filter is serviced using an internal filter instead of a regular bypass filter like Amsoil offers. I think it makes it way too easy to unknowingly introduce contaminates that could cause excessive wear as well. I say before changing the oil again, send in a sample to Oil Analyzer's Inc or Blackstone Labs to see what they have to say. If anything at least you'll have a better idea of how your engine is performing even if you decide to continue with regular intervals.
