Rebuild Kit
Hello everyone,
Where could I find a rebuild kit for my 1983 300sd? I am looking to give it a good work over to relifen it. I know that replacement engines are cheap and I do have two engines that I could put in the car but I want the experience of rebuilding an engine. This is just a thought. The car runs fine but I am thinking of rebuilding an engine on one of my junkers and building it up. Thus, I could just take out the engine I have and throw the other one into my current driver. THanks, DK

What do you want to replace... Pistons are at least 1k for a set.. the oil pump is pretty spendy as well..

decide which motor you want to rebuild, then pull it apart. get the FSM and check the clearances on the cylinders and pistons. check the surfaces of the crank, and the cam. order a rebuild kit from the buy parts link at the top of the page. If you need pistons or cylinders, you will need to take the block to a shop and have the old liners removed, and new liners installed and honed. Pistons will need to be pressed onto the wristpins. everything else you should be able to do on your own to the block.
The Head should have all valve faces checked, and the guides checked and replaced, NOT KNURLED!!! if they are worn. then you can reassemble it. John I am getting ready to do just that to one of the many parts motors I have available to me.

So there isnt a set rebuild kit for the engine? What I mean is gaskets, o-rings, and the such. I will need to take apart the motor and see if I need to send out the head, check the valve clearences, and see how much the pistons are worn down. I just thought I would do the prior research before I get too far into the project.

Performance may have "kits".

Yes, Performance has kits, but I'm sure that Phil could put together the same package of parts and maybe for less money.
That said, buying an "engine rebulid kit" before disassembly is a mistake IMHO. You just absolutely never know what you're going to find when you tear apart an engine. Exploratory surgery is mandatory. It is highly likely that you will need pistons, rings and a rebore, or some here prefer to retain the original pistons and sleeve the block to standard size. I personally am not a fan of this approach due to the extremely stressful life that a diesel piston lives. I have rebuilt a few of these engines and have even reused the crankshaft and bearings when they are in good shape, by carefully marking the bearings and rods making sure that everything goes back in its original position. At the very least you will need to tend to the pistons/cylinders and do a valve jobe including new guides. It is HIGHLY unlikely that you will be able to simply rering without seeing to the cylinders/pistons. Good luck, |

Cheap replacement engines?
Cheap replacement engines? Where do I find one in Texas and how much is cheap? What kind of money are we talking about here?

They're talking about junkyard engines for about $500, or so. A good remanufactured long block is in the $5000 - 7000 range.

You say the engine ran fine? No oil/coolant consumption? No excess blow-by? Started up fine on a cold morning? If that's the case you may not even need to touch the bottom end. I'm finishing up a rebuild on a spare motor out of my first car that was wrecked and boy are these motors easy to work on. All I did was pull the head and send it to a machine shop. They told me all the valves were still within spec and just replaced the exhaust valve guides. I'm replacing the t-chain, its tensioners and guides, as well as the tensioner for the oil pump chain. Also I'm replacing every single gasket and I removed that stupid rear bolt on the ip for future timing adjustments.
