intake manifold cleaning

I'm changing my oil cooler and just removed the intake manifold. Looking inside there's a lot of gunk.
Is there any value in cleaning it?
It there a recommended method?
Anything to beaware of?

I'm getting back on the truck, I'll check back in a few hours.
Thanks in advance.

When I brought my heads for machining, the guy told me to bring the intake manifold with me and he would hot tank/clean it at the same time as the heads. Not a very easy thing to clean for sure. Good luck.

Good advice, I'm going to look into it.
Oil cooler cover "looks" like it has cracks all over it. My buddy says they're just casting lines. One of the threaded posts is broken and was only held in by the helicoil. The cover is going to get replaced.

I'm in the middle of my oil cooler now. ought a can of Gunk Engine cleaner and followed directions on the can. I wasn't completely satisfied so I took the intake to my local car wash bay and used the engine cleaner feature with the high pressure warm rinse. Came out pretty good. I did however remove the air temp sensor, you don't want cleaners and solvents getting inside these sensors! When I got home I hit it again with Castrol Superclean a brass brush and I am happy with the extended effort I put in. Have fun...

How long would a new EGR last if you don't pull the intake manifolds to clean. Only 135,000 k on truck. Don't want to pay eight hours labor if there is another option.

I ran the parts washer through mine and used some stiff bottle type engine cleaning brushes in the passages. It got the worst of it out, at least anything that could clog anything up. The intake takes a beating from the soot in the exhaust gas combined with the oil coming in through the crankcase vent system. Black sludge is the order of the day. Re-routed CCV and no more EGR and it stays nice and clean.
