Better spring than summer

Unfortantly I have been in your shoes. I was even to the point I was going to build a spare engine. I have every thing I need execpt a block to put all the parts in

From the school of hard nocks, remember to clean everything. You might not see the metal particals but they get every where. I thought my oil cooler looked clean after spinning a bearing. Well 10 hours later I blew another engine. Can never stress enough about cleaning everything.

Good luck.

Builder is removing cam bearings and flushing block to clean it out. I will run a fire hose through all cooler lines and cooler. I planned to flush with water/soap mixture and follow up with diesel fuel then oil. Any better plan of attack to flush cooler and line?

I had a spare 454 ready to run. It was stored at the Fire Department and it disappeared. Bummer..

I thought I had the oil cooler clean also. New engine lasted 10 hours A little short cut cost me thousands.

By advise of my machine shop, get new oil lines also. I went and had them custom made while I waited for $40.

I have heard of several people running oil cooler before filter even on brand new coolers, just incase some thing was in the cooler.

Don't forget lifters will contain particles also

I feel your pain. Did that done that last year around the same time. Unfortunately for me, something else when wrong last week . So instead of pissing my summer off like last year, I ordered a new 502 long block . Hopefully I will only be down a week and not like 3 months like last year . Like Jim said, "better spring then summer".

PS.....Just replace the oil cooler. not worth taking chances. I learned the hard way. I did not change my cooler after a spun bearing. New motor lasted less the 10 hrs.

I think I will start a new thread on best oil cooler for the buck. I have not inspected my cooler yet but I cannot see why it would not be possible to fully clean the oil cooler. Is there something in the construction that prohibits fully flushing it?

Tim, did you get a chance to run the boat after the blower rebuild? Any performance improvements?

Do a search you will find them on cleaning oil coolers.
#1 I don't think you could do it for a reasonable price for what they cost to replace.
After my learning experience I cut my open to see what it looked like. It was not loaded with metal but you could see it stuck in between the tubes. When you have thousands spent it is no place to cut corners.
