Head gasket on a dt 466e

Found a bus like mine cheap. How much or how hard is a head gasket?
Thanks in advance

Depends on who is doing the work, you or a shop.
What kind of bus did you find? Don't know what you drive either so if you don't have the tools , time, a place, know- how, it could be pretty expensive,
in the thousands. The gasket is probably reasonable.
Can't wait for others who have done this to report.

I'm Gonna check the liners. I can replace them of needed. I can turn it over.
Probably have to buy a lift.
It's the same process as any other head, right? ( he said hopefully, but knowing better...)

pretty much... with a diesel its a good idea to have the head worked.. make sure its not cracked or warped.. and planed if necessary.. 466E you just have to be careful as you remove injectors and such.. be mindful of the wiring and where it all goes.. I always recommend replacing the head bolts and runninfg a chaser in the holes (NOT a tap).. follow the torque specs from the book and all is good..



checking the liners.. drop the oil pan and pressurize the cooling system (making sure its full)... watch for where the water comes from.. if it comes from inside the cylinders.. - head gasket.. if it drips from around the outside.. - liners..



if replacing the liners - ya gotta put pistons in it too

All good advice. If you're surfacing the head, replacing liners and pistons, gotta wonder if a replacement engine wouldn't be cheaper / easier. Of course, with an AmTran, NOTHING is easy.

the beauty of a DT-466 is that you can in-frame it.. lifting the head out is a lot easier than lifting the full engine out. someone on here recently made a Jig for their front engine bus to essentially roll the head out into the bus on a "dolly".. cant remember the thread.



you can go as simple or as complex as you want.. if you truly just blew a head gasket then you can possibly pull it, clean up the block and head and put it back together.. and it may last a good while.. (an option if you are simply flipping the bus)..



I admit im the type the seizes a failure as an opportunity to update / upgrade / make better than it was..



the DT engines are designed that short of a catastrophic mechanical failure you can do a quality rebuild with the block still in the bus. replacing the liners, pistons, bearings, seals.. and getting another full life out of the engine.



injectors can be taken to a shop and inspected.. only replace if needed (they are pricey)..



the turbo you can inspect and rebuild if necessary.





for the V-8 diesels im more inclined to buy a reman Ready-to-Fly drop in engine just because to do a correct rebuild on one of them you need to pull the engine out and have the block machined and possibly Reman liners installed (if cylinder ridges are too deep).



if a Reman engine is the way you want to go, you can find various levels of rebuilds.. a short-block where you use your current head and all peripgerals, a long block where it has its head and you use your peripherals (injectors, turbo, etc). some long blocks come with a reman turbo. and a full Ready-to-Fly. has everything intake pipe to turbo. and you just drop it in, hook it up and go..



alot has to do with your comfort level, budget, tools, and time. hoisting around 1600 lb engines is no joke. for me personally, being a little dude, taking them apart piece by piece inside the bus is more feasible.
