Detroit Diesel Rebuild

[yachtsmanbill]

Most of the "experts" here will say that its around $4-5000.00 per cylinder. Parts these days typically run about + or - $300.00 per kit. Stay tuned as I am sure this thred will get bombarded with varying responses. Labor is what will kill you, depending on space etc. to perform the work in the boat or out.

I'm in shock,...did you say 4-5,000 per cylinder? that's $40,000 per engine, X2 engines, that equals $80,000 is that correct?

The engines are out of the boat and can be delivered to the shop for rebuild.

My 6V92 kits were around $300 each and the whole rebuild came to around 15K. Mine was a little cheaper than most because I had water ingestion on a 6 year old rebuild. No new hoses were needed as I already had new silicone hoses and constant torque clamps. I also had all new fuel lines so none of that was needed. 3-4K per hole should do a 71 or 92 series. an 8V53 may be a bit less depending on the cost of parts. My parts total was around 3K not including the turbo which I think was around $1500 for a rebuilt one. Everything else was done, blower, heads, new bearings all injectors sent out tested and rebuilt if needed, fresh and raw water pumps rebuilt etc.

Quotes on my 453 engines complete in frame 6-8k. I'm told the 53 series are easier due to the sleeves using Orings to center in the block making assembly easier. The heads on the other hand are 4 valve with very small valves that tend to need reginding if worked hard every 3000hrs with a major in frame every 6000 hrs. So that would work out to $2000 a hole. Heads run about $1100 with a core charge or $1700 with out. The qoutes were assuming replacing the heads.

Ya see? These are real world figures, not the numbers that the bookworms and sock puppets here dream about. You are way ahead of the game taking the blocks to a shop for the work. There is no doubt about the quality of the rebuild at that point. Hot tanking alone is worth the weight of the block.
As a new guy here, please feel free to chime in and ad yer $.02 worth. If you do as much as you can yourself, youll save a ton of dough and learn a lot in the process.
You will find a lot of experts here quote from other experts on how stuff should be done. BEWARE! And take a lot with a grain of salt. Youll figure out in short order who to thank and who will make you think (twice I hope!) Now go get yourself a BIG jug of Go-Joe hand cleaner and get to work! ws

Now yer talkin! I do this on a meager pension, so my motto is "I aint cheap, just frugal". Welcome aboard and please, enjoy your boat. So many seem not to be able to these days! ws

Pulled two 4-53t's out and away from anything labeled "marine". Had a diesel farm tractor shop recommended to me and found parts thru a engine machine shop rather that thru Detroit. Took them to the shop during the winter when he was hungry and saved a bunch. Total for rebuild incl kits, injectors, rebuilt turbos (less heads and cranks, they were OK) was under $7k. So had I gone w/ the "professionals" @ $4k/hole I'd be kicking myself.

I have overhauled my 6V53s twice over the years. The last time was was about 8 years ago. I recall that the parts about $5k per engine. I have no first hand information, but I have heard that some 8V53 parts like heads and exhaust manifolds are harder to come by than 6V53 parts. I bought new casting heads with rebuilt valves gear for under $900 each (with core) from DDC when I did my last overhaul. I don't know that new 8V53 heads are available at any price.
