How can I bypass a oil cooler on a 1991 350 block? Can I take the lines off and plug them? THANKS MIKE

you would need to take the block off that the oil cooler lines go to. The one the filter screw on to, then get a regular adapter for the oil filter.

Where could I get the adapter? What would it be called?

looks like it.
I've never had a 350 with an engine oil cooler... but on a 6.2L diesel, the lines come straight off the side of the block. Remove the lines and install NPT plugs.
IMO oil coolers compromise reliability. A ruptured line really wrecks you day (and/or your engine
), leaky lines are high maintenance, and they retain nearly a quart of dirty oil each oil change.

Hmmm strange......... I have never had a problem with my oil cooler on my 350. The lines are hard steel and thick hydraulic lines to the cooler. They have never leaked, been grabbed by brush, hit by rocks, or caused any problem. The oil cooler drains completely at each oil change. If anything, it adds to the longevity of your engine.
If you need to bypass them. I suggest you either get the stock oil filter adapter or hook/loop them together. If you plug them your engine will be a little starved for oil and might make a little noise before it blows.

I am putting a 1991 motor in my 1979 blazer and my 79 does not have a cooler.ntsqd said:

My 89 Blazer has the NPT plugs screwed into the adapter. Apparently the cooler was leaking and the previous owner did not want to fix it the right way. I have owned it for two years now and no problems.

Just use the oil filter adapter that is on the engine in your 79 now.barneybasher1010 said:
I take it that you don't have the '91's cooler? I've no idea what was done in K5's, but my '79 3/4t Sub's SBC had the cooler.barneybasher1010 said:
I could see in cold country one being of little help, but since ~1/3 of the total heat produced by an engine is dumped into the oil I think a cooler is a good idea for anywhere else. There are two reasons for changing engine oil, gunk & fuel that it's picked up and the destruction done to it's chemical structure by that engine heat.

Then go buy a cooler . Its a great thing to have . It may keep your oil in better shape between changes , reduce engine wear , and give you something to brag about .
Just carry a piece of hose , and a couple plugs that fit the oil adapter ..... just in case .
Actually EVERYONE who owns an old truck needs to carry enough stuff to make it home
