200tdi to 300tdi conversion or recon 200tdi

I'm trying to get some suggestions on what to do with my 200tdi in my 110. I have spent the better part of two years chasing down all sorts of issues like major oil leaks, sluggish performance, heating and cooling problems. The most recent issue of intermittently belching coolant and/or burning coolant has me thinking maybe its best to start fresh and upgrade at the same time. With rehabbing an old house, a 4yr old, a 5 month old, a house still on the market I don't have a lot of time, but I also cant bank roll a full restoration.

I'm fairly certain I need a headgasket and top end rebuild and I'm struggling with putting more money into something where parts are harder to find and might need more work or bite the bullet upgrade to the 300 and start from a known position. Or give the headgasket a go and see what shakes out?

We just did a head refresh on a 200TDI for around $500 in parts and machine work not counting labor.
That is way cheaper than a 300TDI.
Add a set of reman injectors and glow plugs and you are not much over $1000.
The 200TDI is often a love hate relationship.

Thanks. I am definetley in the hate corner for now. I'm going to give it a go myself. Is it worth rebuilding the valves while I'm in there? That seems a little bit more involved than I was hoping for. Too bad the only reconned head available is from Urban.

A head gasket change is simple. Maybe a couple of hours. As a minimum, you would want to lap the valves and install new valve stem seals, both of which are pretty simple. If more work is "needed" on the head you won't know until it is open. If anything else is desired or needed, you should be able to get the head work done at any local engine shop. It is all straightforward and normal stuff.

Changing to a 300 is a large project as it will not just bolt right up. Custom work is involved.

It would be cheaper to pay Boston's premier repair shop to do the top end of your 200Tdi than you swapping in a 300Tdi yourself.

You can't swap in a 300 without modifying the chassis. That or buy the wonky conversion parts from Steve Parker Land Rover. Just fix what you have. Usually the bottom end is fine on these and you just need the head refreshed.

My local shop cleaned, inspected and skimmed my 200 head, then did a full valve job. Parts and labor was about $275 out the door iirc. Good injectors are key.

All this is moot though if the overall air and fuel systems are not balanced properly.

Sounds like I'm going to give the 200 another go. I've decided to try it myself, so we will see what the outcome is. There are some other bottom end issues with the camshaft oil feed, but not enough to cause damage.
