ballpark estimate for an overhaul?

Question

i'm looking for a rough estimate on the cost to have a dodge slant 6 rebuilt.

Answer 1

That's going to depend on how much work the engine is going to need. Being it's a slant 6...... it's an older engine, and probably has quite a few miles on it. Those engines had a reputation for running forever. But, for a complete rebuild, the engine will be completely disassembled and cleaned inside and out. They will most likely check the cylinder walls, and depending on their condition, either hone or bore them. Honing will correct minor scratches and provide a new surface for the new rings to seat. If the cylinders are really gouged up or they have worn so that the cylinders are not perfectly round, they will have to bore the cylinders anywhere from 5-30 thousands of an inch. This will require new, oversized pistons and rings. They will also check the crankshaft for damage and polish the journals and install new bearings. New bearings will also be installed on the piston rods. A new oil pump should be installed also. New seals and new freeze plugs should be installed. The cylinder head will be gone through and worn valves and valve guides will be replaced and new seals installed. It will also be checked for warpage, and be milled flat to seal properly with the engine block. The engine will be completely re-assembled and, if possible, test run. The cost for this will vary on how much work has to be done to restore the engine back to running condition. It's been a while since I've had an engine rebuilt, so I'll guess that you'll spend about $1,000 or more, depending on how much has to be done. If matching numbers, or having the original motor is not a big concern for you, check the website below. For about $1200, you can have a rebuilt slant 6 with a warranty, and you can send them your old engine as a core.

A lot depends on what you mean by 'rebuild'. There are many ways to skimp. but i'll say 2-3 thousand.
