It’s still going strong. I am only looking to rebuild it as a precaution and because I am bored and don’t have a project at the moment!

Changed the oil pump and the pressure is good when cold - 55-60psi but drops to 8 psi when warm again. So I'm thinking cam or crank bearings and engine out time.

The question is do I rebuild the engine myself or buy a turners recon unit (expensive i know)? I've never stripped an engine but I'm pretty reasonable with mechanics now. Is it realistic to do myself? I read that the cam shaft needs reamed to the bearings, which I won't be able to do. Any idea on how long it would take to rebuild the block?

if you buy the correct cam bearings they are to size no reaming necessary, crank bearings are straight forward

If I can do it you can do it.
Mines a 300Tdi and I only changed the fron cam bearing shell. The cam shaft was a nice snug fit in to the new bearing. No reaming to be done. 200's might be different.

Do the two oil pump gears rely on a certain space to the housing? Could that be worn?

Even if I reuse my old camshaft?

That gives me a bit of confidence. It’s funny part of me is kinda glad I get to take the engine out and strip it down.

Have you tested the compression? You'll have to decide if you are just doing the crank and cam bearings or a full refurb.

payydg said:

That was going to be my next step. I’m tempted to do a full rebuild

I would balance the investment, in terms of time and money, against the condition of the vehicle and the length of time I intended keeping it. For me it was an easy choice because I'd done the galv chassis and bulkhead rebuild.

payydg said:

You raise a good point. I’ve done the galv chassis too. Bulkhead is ok plan on keeping it for as long as I can. The mrs has another car so we can do with out it. Mostly use it for camping on the westcoast

Sounds like it's going to be worth the effort then Mine was so smooth and quiet when I started it up for the first time, it was amazing. The Mrs and I just turned and looked at each other and both mouthed 'it's so quiet'! Pulls great too.
