    Ok Guys and Gals
    I have What I belive to be an OEM oil cooler, Well It broke yesterday And I have yet to find one like it. So in the mean time I removed the lines from the Adtapter that is between the filter and the block and I pluged them off Untill I can replace the cooler. What I would like to know will this work for the time being? Will the oil still get filterd right ? I do have oil press. What do you guys think?

    I am not the expert, but I think if it were me I would loop a small piece of hose between the inlet and outlet so the flow will remain the same ( without and cooling going on). I think if you plug the lines you MAY cause the flowpath of the oil to stop on either its way to the filter or the engine. Anyone else have a better feel for this please chime in......

    I beleive it might work for a temp get you home cuz chevy has a bypass in side the motor, what the oil filter srews on to on a normal 305/350. But I don't think it is a real fix. You can unsrew the adapter and put the filter on like a normal engine has it. Then that would be all right for a permanent temp fix. Look around for a new one BUT don't mess up the hydralic lines quoted them once for my old sub 2x4 and they were $150 each from GM.

    My opinion on engine coolers is that it's an extra two hoses vulnerabkle to damage and able to leak that could be eliminated with the removal of the opil filer adaptor.
    You can remove the oil filter adapter that has the outlet and inlet hose for the oil cooler with two bolts. Promptly discard it. Then, bolt on a standard oil filter adaptor, available new from your gm counter or used from any junkyared here to india. Then make sure your radiator is up to snuff, which is should be if it's a four core with a shroud.

    I had new lines made (with custom bend to go around ORD frame brace) for $100/pair.

    If I understand your setup correctly, You have two oil lines that come from the adapter and go to the oil cooler. If you remove the oil cooler from the picture, you'll need to join the two lines and allow oil to circulate through the lines. Otherwise you'll be circulating oil through the bypass and not filtering it. In a sense, the filter will be forced out of the picture.

    OK... here is my opinion;

    The oil stem (where the oil filter schrews too) as a place where the 2 lines come out. remove the 2 lines, and insert some plugs there.

    I have had the exact same problem that you are encountering.

    I ended up ordering a perma cool oil cooler from summit racing, but I couldn't find any fitting for any cooler except for factory that would bolt up. I ended up using a couple pieces of rubber house and house clamps, but I have not had any problem with that.

    I actually had one of my oil cooler lines burst, but it was in a different place. that part where the where the hose clamps and rubber line where held great.

    by the way the factory oil cooler is $300! [​IMG][​IMG] I would try to find a replacement out of a junk yard if you are going to replace it.

    on my other k5 I remember the stem, and put a stem in for a non-factory oil cooler. now it just bolts up with no oil cooler / oil cooler lines option (removed everything!)...

    I'd say your options are this; remove the oil cooler and lines completely. there are tons of 350's on the market, in trucks, that have had a very long live without an oil cooler. that would be most desirable, but not required.

    option number 2 is to find one in a junk yard.

    option number 3 would be to get a different aftermarket oil cooler from summit or someplace like that, and replace the oil stem and lines also so there to fit / accomodate the oil cooler and oil stem. if would be cheaper then the factory (although more work).

    the fittings for the GM, from what I understand, are not standard, and there are not adapters to make them accomodate normal sizes (reducers etc.). it would probably worth the extra effort to get a new oil stem, new oil cooler, and cooler lines (could go braided all the way) from summit or jegs or some place like that if you want to run a cooler.

    you get one out of a junk yard, and you never know how long it is going to last. if you go without one you probably are not going to have peace of mind. (if you can remove it, and have peace of mind then that is what I would do unless you do a lot of heavy towing with it)

    IMHO just get rid of it. Unless you are doing alot of heavy towing I think they are worthless. It is just more places to leak and more stuff in the way if you need to work on it from underneith. Mine will be gone when I do my next oil change.

    You just have to bend them a little.. I had no problem getting the brace in.

    Thanks Sparky
    I was afraid that the oil would not get filtered, I couldn't put my hoses together so what I'll do in the mean time is run to the junk yard and get the filter part untill after X-mas then I'll get a new one from Summit.
